Introduction to the Mathematics Test Specifications and Blueprints

Introduction

The primary purpose of the Test Specifications and Blueprints is to provide the consistency necessary for the development and administration of the Oregon Assessment of Knowledge and Skills (OAKS). OAKS provides critical data for Oregon’s accountability system which meets Peer Review Requirements of the Elementary and Secondary Education Act. All students in grades 3 through 8 are required to take the reading and mathematics assessments. All students in grades 5 and 8 are required to take the science assessment. In high school, at grade 11, reading, writing, mathematics, and science are required assessments.

OAKS is also one way for students to demonstrate proficiency in the Essential Skills of reading, writing, and mathematics, which will be necessary for earning a high school diploma beginning with seniors graduating in 2011-2012.The requirement in mathematics to demonstrate proficiency in Applying Mathematics in a Variety of Settings will begin with the class of 2014. In addition, English Language Proficiency Assessment (ELPA) is required for non-English speaking students until they acquire sufficient skills in English to exit the program. Social Sciences is an optional assessment.

Test specifications provide guidelines for item writers, who are typically Oregon teachers, on what content may be tested and how items must be written. These specifications lead to test blueprints that outline test design and the number of questions to be tested in each score reporting category (SRC). The Test Specifications and Blueprints document is an important resource, not only for item writers and reviewers, but for educators administering OAKS and the general public who are interested in understanding the content and format of test items.

Background

The purposes of the Oregon Statewide Assessment Program are (1) to provide information on individual student achievement on performance standards set by the State Board of Education at grade and benchmark levels; (2) to provide information for federal Elementary and Secondary Education Act requirements and for policy decisions by the legislature, the governor, the State Board of Education, and local school districts; (3) to support instructional program improvement efforts; and (4) to inform the public about student achievement in Oregon schools.

The Oregon Statewide Assessment is different from national norm-referenced tests used in many districts and states. The Oregon Statewide Assessment is a criterion-referenced assessment based on the Oregon Content Standards. As a result, the types of scores produced from the Oregon Statewide Assessment are somewhat different from those produced by national norm-referenced tests.

Oregon educators contribute to the test development and alignment process by serving on advisory committees called Content and Assessment Panels. Stakeholders in these committees are involved in each phase of the development of these specifications to assure that they accurately and clearly explain the overall design of the test and describe the specific content that might appear on the test to measure the knowledge and skills described in the content standards.

The Oregon Assessment of Knowledge and Skills test questions use multiple-choice and computer-scored constructed response formats. Each multiple-choice item has only one correct answer while computer-scored constructed response items may have many correct answers. A computer electronically collects and scores responses which are scored against the answer key to produce a raw score. The raw score is

Mathematics, Grade 8

converted to a scale score called a Rasch unit or RIT score. Students receive a scale score based on the number of questions answered correctly compared to the total number of questions on the form—taking into account the difficulty of the questions. Students are not penalized for guessing.

The content of these specifications reflects the skill expectations outlined in the State of Oregon Mathematics Content Standards for Kindergarten through Grade 8, adopted in December 2007, and the Oregon High School Mathematics Content Standards, adopted in June 2009.These standards were developed, in part, to align to the 2006 Curriculum Focal Points for Pre-kindergarten through Grade 8 Mathematics: A Quest for Coherence, published by the National Council of Teachers of Mathematics. The high school standards were developed in the same vein as those for grades K-8, to allow students to be accountable for fewer topics, but to understand the concepts more deeply.

Statewide and Local Assessments Statewide assessments are multiple-choice and computer-scored constructed response tests of knowledge and skills that are developed and scored by the state. Local assessments include performance assessments that may be scored using statewide scoring guides that are administered and scored at the local level (see Appendix F). Local assessments are not included in state accountability reports, e.g. AYP reports.

Paper/Pencil Administration Paper/Pencil fixed form tests are no longer administered in Oregon. All tests are computer-adaptive, as of 2011-2012.

Electronic Administration For the mathematics OAKS online tests, two testing opportunities are offered each year for students in grades 3-8 to participate in fully-adaptive testing. Three opportunities are offered each year for high school students in grades 9-12 who have had the opportunity to learn the high school content. In this fully-adaptive format, the accuracy of the student’s

responses to questions determines the next item the student will see. Having the tests fully adaptive allows for more precision in measurement and less frustration for the students.

Beginning with 2011-2012, students who need to have the test read to them may access the text-to-speech function of OAKS Online. The OAKS Online test delivery system will also be available to students with visual impairments who use Braille, providing the same number of testing opportunities as the general student test. (Beginning with 2011-2012, the paper-based Braille assessments will no longer be available.)

Online practice tests of sample items for each grade are available for students who may need practice using a scrollbar, new item types, or other features of OAKS Online. The practice tests are also adaptive in order to simulate the actual OAKS test; you must use Mozilla Firefox to access the practice tests. Downloadable fixed-form sample tests are also available, with answer keys provided. Sample tests and OAKS Online Practice tests can be found at http://www.ode.state.or.us/search/page/?id=441.

Transition to Common Core State Standards and Smarter Balanced Common Assessment Beginning with the 2014-2015 school year, Oregon will be utilizing assessments based on the Common Core State Standards for English/Language Arts and Mathematics. The 2014-15 assessment for these subjects will comply with all criteria set forth by Smarter Balanced Common Assessment. Oregon is part of the collaborative consortium of states developing Smarter Balanced and will also use common achievement standards. This work is underway and will be in development until the transition is made in fall 2014.

See (www.ode.state.or.us/go/commoncore) for up-to-date information on the Common Core State Standards and http://www.smarterbalanced.org/ for information on the Smarter Balanced Common Assessment.

Mathematics, Grade 8

On the OAKS mathematics tests:

Students are strongly encouraged to use calculators. Rulers,

manipulatives, and other tools commonly available to all

students are also encouraged. No problems require the use of a

calculator and no more than a four-function calculator is

needed for any problem, although scientific calculators are

highly recommended for use at grades 8 and 10. On-screen

calculators are included in the OAKS Online tests, but students

are also allowed to use the calculators they regularly use for

class work. (See the Test Administration Manual for

guidelines.)

For each of the grades 3-8, this statement precedes all the core

standards: “It is essential that these standards be addressed in

contexts that promote problem solving, reasoning,

communication, making connections, and designing and

analyzing representations.” Therefore, any content standard

may be assessed using a context or a problem-solving situation.

Likewise for high school, “It is essential that the high school

mathematics content standards be addressed in instructional

contexts that promote problem solving, reasoning and proof,

communication, making connections, designing and analyzing

representations, and reflecting on solutions.” Similarly, any

content standard may be assessed using a context or a problem-

solving situation.

For all grades, every student should understand and be able to

apply all mathematical concepts and skills from previous grade

levels to the standards of their current grade.

Each OAKS mathematics test item will measure only one

Score Reporting Category (SRC). The Score Reporting

Categories are the three “core standards” for each grade. Each

core standard is associated with four to nine content standards.

Grades 3-8 each have approximately 20 content standards. The

high school standards include three disciplines of mathematics

– Algebra, Geometry, and Statistics. Within each discipline

“strand” there are two to three core standards. These core

standards provide the major concepts and processes for

teaching and learning across the grades. Beneath each of these

core standards are from three to eight content standards which

provide the details necessary for curriculum and assessment.

The score reporting categories are shown in the diagram on the

next page.

The new mathematics standards also frequently mention

“fluency” with skills and concepts. See the page following the

Score Reporting Categories chart for a complete statement as

to the intended meaning of “fluency” for OAKS Online.

The pages following the Fluency Statement contain a more detailed examination of the test content for mathematics.

Fluency Statement to Accompany Oregon Assessment of Knowledge and Skills

Test Specifications and Blueprints

What are the Main Messages of NCTM's Principles and Standards (2000) Regarding Computation?

Computational fluency is an essential goal for school mathematics (p. 152): Embedding Fluency in Conceptual Understanding

The methods that a student uses to compute should be grounded in understanding (pp. 152-55). Students can achieve computational fluency using a variety of methods and should, in fact, be comfortable with more

than one approach (p. 155). Students should have opportunities to invent strategies for computing using their knowledge of place value,

properties of numbers, and the operations (pp. 35 and 220). Students should investigate conventional algorithms for computing with whole numbers (pp. 35 and 155).

Goals of Fluency

Students should know the basic number combinations for addition and subtraction by the end of grade 2 and those for multiplication and division by the end of grade 4 (pp. 32, 84, and 153).

Students should be able to compute fluently with whole numbers by end of grade 5 (pp. 35, 152, and 155). Students should be encouraged to use computational methods and tools that are appropriate for the context and

purpose, including mental computation, estimations, calculators, and paper and pencil (pp. 36, 145, and 154).

What is Computational Fluency?

NCTM Principles and Standards of School Mathematics (2000) defines computational fluency as having efficient and accurate

methods for computing that are based on well understood properties and number relationships.

The National Math Panel Report cites the NCTM definition of computational fluency in its report when it uses this phrase. For

further clarity, on page 41 of chapter 3 of the Task Group Reports of the National Mathematics Advisory Panel, there is a discussion

of the critical foundations for the study of algebra: (1) fluency with whole numbers, (2) fluency with fractions, and (3) particular

aspects of geometry and measurement. The National Mathematics Advisory Panel Final Report (2008), page 17-20, reiterate three

clusters of concepts and skills – called Critical Foundations of Algebra – reflecting their judgment about the most essential

mathematics for students to learn thoroughly prior to algebra course work.

The excerpt from page 41 of chapter 3 (Report of the Task Group on Conceptual Knowledge and Skills) is below:

1. Fluency with whole numbers

By the end of the elementary grades, children should have a robust sense of number. This sense of number must include

understanding place value, and the ability to compose and decompose whole numbers. It must clearly include a grasp of the

meaning of the basic operations of addition, subtraction, multiplication, and division, including use of the commutative, associative,

and distributive properties; the ability to perform these operations efficiently; and the knowledge of how to apply the operations to

problem solving. Computational facility rests on the automatic recall of addition and related subtraction facts, and of multiplication

and related division facts. It requires fluency with the standard algorithms for addition, subtraction, multiplication, and division.

Fluent use of the algorithms not only depends on the automatic recall of number facts but also reinforces it. A strong sense of

number also includes the ability to estimate the results of computations and thereby to estimate orders of magnitude, e.g., how many

people fit into a stadium, or how many gallons of water are needed to fill a pool.

2. Fluency with Fractions

Before they begin algebra course work, middle school students should have a thorough understanding of positive as well as negative

fractions. They should be able to locate both positive and negative fractions on the number line; represent and compare fractions,

decimals, and related percents; and estimate their size. They need to know that sums, differences, products, and quotients (with

nonzero denominators) of fractions are fractions, and they need to be able to carry out these operations confidently and efficiently.

They should understand why and how (finite) decimal numbers are fractions and know the meaning of percentages. They should

encounter fractions in problems in the many contexts in which they arise naturally, for example, to describe rates, proportionality,

and probability. Beyond computational facility with specific numbers, the subject of fractions, when properly taught, introduces

students to the use of symbolic notation and the concept of generality, both being an integral part of Algebra (Wu, 2001).

3. Particular Aspects of Geometry and Measurement

Middle-grade experience with similar triangles is most directly relevant for the study of algebra: Sound treatments of the slope of a

straight line and of linear functions depend logically on the properties of similar triangles. Furthermore, students should be able to

analyze the properties of two- and three-dimensional shapes using formulas to determine perimeter, area, volume, and surface area.

They should also be able to find unknown lengths, angles, and areas.

Item Specifications

Oregon Assessment of Knowledge and Skills (OAKS) is a statewide assessment scored by the state. It is a required assessment that provides the

base for the accountability system. The OAKS also measures proficiency in the Essential Skills and is one way to determine student’s eligibility

for a high school diploma or modified diploma beginning with the graduating class of 2014.

Criteria for All OAKS Test Questions

Test items must:

be appropriate for students in terms of grade-level difficulty,

cognitive complexity, reading level, interests and

experience.

be free of age, gender, ethnic, religious, socioeconomic,

or disability stereotypes or bias.

provide clear and complete instructions to students.

Graphics Criteria

Graphics are used in OAKS to provide both necessary and

supplemental information. Some graphics contain information

that is necessary for answering the question, while other graphics

illustrate or support the context of the question.

Graphic displays, their corresponding items and answer

choices will appear on the same screen for online items.

Shading and color will be minimized. It will be used to

make a figure’s size, shape or dimensions clear, and not

solely for artistic effect.

When objects or regions of particular colors must be

identified from a graphic, the objects or regions will be

labeled as to their color.

Graphics used for computer scored constructed response

items are displayed within a grid space and allow students

to manipulate answer graphics and answer choices.

Item Style and Format Criteria for Multiple-Choice Items

Test items will be in the form of questions - or sentences

that require completion.

Each item will have three, four, or five answer choices.

Students will be told in the test directions to choose the

best answer from among the choices.

Answer choices will be arranged one of three ways

beneath the question: vertically, horizontally, or in two

columns (i.e., A and B in the left column, C and D in the

right column).

Neither “None of the above” nor “All of the above” will

be used as one of the answer choices. “There is not

enough information to tell” is an allowed answer choice.

Test items may be worded in the negative (“Which of

these is NOT …”), but this structure will be used only

when it offers substantial advantages for the item

construction.

Items should be free of absolute wording, such as

“always” and “never,” and may have qualifying words

(e.g., least, most, except) printed in CAPS for emphasis.

Masculine pronouns should NOT be used to refer to both

sexes. Plural forms should be used whenever possible to

avoid gender-specific pronouns (e.g., instead of “The

student will make changes so that he ….,” use “The

students will make changes so that they….”).

An equal balance of male and female names should be

used, including names representing different ethnic

groups.

29 Oregon Department of Education Office of Assessment and Information Services

Test items aligned to standards may contain

extraneous information.

Stacked English-Spanish test items are used on

electronic tests for the English-Spanish OAKS.

Each Score Reporting Category will have items with a

range of difficulty and complexity levels.

Each test item will measure only one Score

Reporting Category

Item Style and Format Criteria for Computer-Scored

Constructed Response Items

Test items will be in the form of questions that ask

for at least one object to be created or matched to

an existing picture,

Each item may have many discrete and correct

answer choices.

Test items may be worded so that not all answer

choices are used to construct the correct response.

An equal balance of male and female names should

be used including names representing different

ethnic groups.

Test items aligned to standards may contain

extraneous information but only to enhance the

students’ understanding of the question.

Side-by-side English-Spanish test items of this type

are under development.

Additional Criteria for Mathematics Test Questions

Except in translation items (name to numeral, numeral to

name), numbers will be expressed as numerals.

In general, numbers zero through nine should be

presented as words, and numbers 10 and above

should be presented as numerals. In the item stem,

any numbers needed to compute answers should be

presented as numerals.

Commas will be used in numbers with four or more

digits.

Decimal numbers less than one will be written with

leading zeros.

All fractions will be written with a horizontal bar

separating the numerator and denominator.

If the answer choices for an item are strictly

decimal numerals or integers, they should be

arranged in ascending or descending order, with the

place values of digits aligned. An exception would

be when this ordering of options might give a clue

as to the correct option. When the item requires the

identification of relative size or magnitude, choices

should be arranged as they are presented in the item

stem.

If the answer choices for an item are neither strictly

numerical nor denominate numbers, the choices

should be arranged by the logic presented in the

question or by length.

Answer choices will include units, as appropriate.

Computations required in test items will not be so

complicated that they take an inordinate amount of

time to complete, even with calculators. Instead,

reasoning within the context of the items is

emphasized.

Test items will be appropriate for students in the

assigned grade in terms of reading level, interests,

and experience. For mathematics test items, the

reading level should be approximately one grade

level below the grade level of the test, except for

specifically assessed mathematical terms or

concepts.

Standard units of measure should be spelled out,

except in graphics where an abbreviation may be

Mathematics, Grade 8

Mathematics Test Specifications and Test Blueprints

30 Oregon Department of Education Office of Assessment and Information Services

used (e.g., ft or yd). Abbreviations that also spell a

word must be punctuated to avoid confusion. For

example, to avoid confusion with the preposition

“in,” the abbreviation “in.” should be used for the

unit of measure “inches.” If an abbreviation is used

in a graphic, an explanation of the meaning of the

abbreviation should be included in the stem. Metric

units may be abbreviated.

In addition (See: Test Administration Manual at

http://www.ode.state.or.us/go/tam )

Students are strongly encouraged to use calculators –

either the on-screen calculator, their own, or one

provided by the school.

Rulers, manipulative and other tools commonly

available to all students are also encouraged. No

problems require the use of a calculator and no

more than a four-function calculator is needed for

any problem, although scientific calculators are

highly recommended for use at grades 8 and 10.

A reference sheet containing appropriate formulas

and conversions is provided to students. If formulas

not on the sheet are needed, they should be

included with the item.

Mathematics Test Blueprint

Introduction

The blueprints used to construct Knowledge and Skills Tests for

Mathematics prescribe the:

Score Reporting Categories (SRC) included on each

test,

The cognitive demand and difficulty level of items as

distributed on a test form,

the number and percentages of test items from

each SRC included on each test, and

the total number and percentages of operational and

field test items included for each test.

Teachers and other educators have historically played a vital role

in the development of these specifications and blueprints by

serving on Content and Assessment Panels and other review

groups. These groups have advised the Department as content

standards have been developed, and have helped establish

priorities on which standards to assess and the weighting of the

strands within each content area assessment.

Alignment of Test Items to Content Standards

Test items are carefully aligned to content standards at the

appropriate grade level through a rigorous process at two points in

the test item development process:

At item development workshops, item writers are provided

with adopted content standards and content standard

elements to which they must write test items; during a peer

review process, this alignment is verified by another grade

level item developer and the grade-level facilitator..

Alignment of items to the standards is further verified

during a review by members of a Content and Assessment

Panel, who ensure items not only match the standards, but

also verify overall quality and appropriateness. Reviewers

either accept items as a strong match to the targeted

standards, edit items to achieve a strong match, or reject

items which do not strongly match the standards.

The Appendix to this document includes additional evidence

describing procedures ensuring alignment during item,

development, including descriptions of Item Development and the

Life of an Item.

Content Coverage

Prior to item writing activities, item databases are reviewed to

determine the extent that the available items represent the

emphasis and content in the standards. If any content standards are

underrepresented in the item pool, they are identified and targeted

specifically for additional item development. This assures that the

item pools will have sufficient numbers of items aligned to the

each of the content standards to allow the test algorithm to deliver

tests which follow the blueprint for content, difficulty, and

cognitive complexity.

For electronic administration, all tests and the item pools from

which they are constructed follow the weighting of each score

reporting category as reflected in the chart titled “Weighting of

Mathematics Score Reporting Categories.” Items aligned to the

same SRC are selected to provide a range of difficulty so that the

progressive nature of the test is maintained as students of varied

Mathematics, Grade 8

Mathematics Test Specifications and Test Blueprints

32 Oregon Department of Education Office of Assessment and Information Services

ability levels are presented with items most appropriate to their

ability from that pool. Although a student may not see an item

addressing every one of the standards in a single test event, the

item pool contains multiple items for each content standard at a

variety of difficulty levels and cognitive complexity.

In addition, the adaptive algorithm specifically considers alignment

criteria when drawing test items. As a result, we accomplish the

dual purpose of creating a test form that is appropriately developed

for each student and it meets the criteria set forth for alignment

(e.g., balance of representation, depth of knowledge).

In order to report subscores, or scores for SRCs, no fewer than six

items will be used for each SRC. Online tests report total test

scores and scores for SRCs. (Subscores)

Additional Test Design Criteria

Each item assesses only one SRC at one grade.

Each item assesses only one content standard at one grade.

Online-adaptive test opportunities provide a range and breadth of

items within each SRC and content standard. Test pools attempt to

provide a minimum of one item at each difficulty level for each

content standard. Test pools range in size from 800 to 1500 items.

Key placement cannot be controlled for online-adaptive

assessments, so to ensure more random correct keys, item writers

are instructed to rotate the correct key for their items during item

authoring.

English test blueprints provide the criteria for all English-Spanish

tests. Test pools and are designed to match the English test

opportunities.

The chart below shows the score reporting categories for each of the grades and the percentage of questions on a test that assess each score

reporting category. For example, at grade 5, 35% of the items on a test assess Number and Operations and Data Analysis, which equals about 14

items on a 40-item test. The second chart, on the next page, is an expanded view of the criteria for test weighting.

Content Coverage and Weighting

*During an individual student testing session, the test algorithm selects items from each SRC, targeting the percentages indicated. Furthermore, items are selected to match the target item difficulty level, determined by the student’s performance on previous items, and also to match the Cognitive Demand Distribution Goals for the test. The numbers of items available in the item pool for each SRC are sufficient to allow three tests per student each year, without the student seeing any item more than once.

Target Cognitive Demand and Item Difficulty Distribution

The mathematics test pools are designed so that items having a

range of Cognitive Demand and a range of difficulty are

included for each student test opportunity. The target item

pool difficulty distribution for the Grade 8 test is outlined in

the chart. A target range of cognitive demand item delivery is

also included. (See Appendix B, Cognitive Demand and RIT

by Difficulty for all grades). The three Cognitive Demand

levels used to qualify Oregon’s test items are:

Recall: Item requires a student to recall a fact,

information or procedure.

Skill/Concept: Item requires a student to use skill or

concept, including thinking that requires two or more

steps.

Strategic Thinking: Item requires a student to use

reason, develop a plan or use a sequence of steps.

Online adaptive tests provide students with questions at the

beginning of the test at or about the mean RIT level and as the

student responds, the test item delivery system makes

adjustments by selecting appropriate items for each student

based upon their correct and incorrect responses.

Student scores on each test will vary due to performance and

the set of unique test items issued to the student. Generally,

students will earn scores between the maximum high and

minimum low range. The following are the possible high and

low RIT student scores for grade 8 tests, within one or two

points, based on a given year’s item pool.

tests in the various content areas. These may be used by educators to target instruction and inform parents and students of the

expectations for students to be considered proficient at a particular grade level.

The Achievement Level Descriptors are based on a sampling of a larger set of content outlined in the State of Oregon Content

Standards for Kindergarten through Grade 8 (2007) and the State of Oregon High School Mathematics Standards (2009). Results for

individual students are only one indicator of student ability as measured at the time of testing. These statements give a general

description of what most students know and can do within a particular band of achievement and are presented in the order of the way

they are reported rather than by importance or test emphasis.

Students who score at or within a particular level of achievement possess the bulk of the abilities described at that level and generally

have mastered the skills described in the preceding achievement levels.

Achievement Level Descriptors for each subject area were developed by groups of parents, educators, and business people who

worked with state officials to establish the minimum scores required for Exceeds, Meets, Nearly Meets and Does Not Yet Meet.

LOCAL ASSESSMENTS REQUIRED BY OAR 581-22-0615 ASSESSMENT OF ESSENTIAL SKILLS

Local Performance Assessments School districts and public charter schools that offer instruction at grades 3 through 8 or high school must administer annual local performance assessments for students in grades 3 through 8 and at least once in high school for the skill areas of writing, speaking, mathematics problem solving, and scientific inquiry. The purpose of the local performance assessment requirement is to ensure that students in grades 3 through high school are afforded opportunities to learn and to receive feedback regarding their progress toward meeting specific state standards throughout their years in public schools.

A local performance assessment is a standardized measure (e.g., activity, exercise, problem, or work sample scored using an official state scoring guide), embedded in the school district’s or public charter school’s curriculum that evaluates the application of students’ knowledge and skills. Local performance assessments must be designed to closely align with state standards and to promote independent, individual student work.

School districts and public charter schools may either use a work sample scored using an official state scoring guide or a comparable measure adopted by the school district or public charter school to satisfy the local performance assessment requirement. Appendix E – Work Samples and State Scoring Guides of the 2009-10 Test Administration Manual provides guidance for those school districts and public charter schools choosing to use a work sample to satisfy this requirement.

Assessment of Proficiency in the Essential Skills As part of the new graduation requirements, high school students must demonstrate proficiency in a set of Essential Skills, which are defined as process skills that cross academic disciplines and are embedded in the content standards. Starting with the graduating class of 2012, high school students must demonstrate proficiency in the Essential Skills of Reading, Writing, Speaking, and Mathematics.

Students may demonstrate proficiency in these Essential Skills using any of the assessment options approved by the State Board of Education.

As of May 2009, the Oregon Assessment of Knowledge and Skills (OAKS) is one of the approved assessment options for the Essential Skills of Reading, Writing, and Mathematics. Another approved option for the Essential Skills of Writing, Speaking, and Mathematics is the completion of work samples scored locally using an official state scoring guide. Appendix D – Requirements for Assessment of Essential Skills of the 2009-10 Test Administration Manual provides guidance for those school districts and public charter schools choosing to use a work sample to satisfy this requirement.

The Assessment of Essential Skills Review Panel (AESRP), which consists of experts from school districts and post-secondary education institutions, reviews and recommends additions or changes to the list of approved assessment options. The AESRP bases its recommendations on evidence provided by the school districts, research organizations, and other experts that the proposed assessment option accurately measures the Essential Skill. The State Board of Education then makes the determination whether to adopt the AESRP’s recommendations. ODE anticipates that the State Board of Education will approve additional assessment options based on recommendations from the AERSP in the coming months. In addition, the AESRP is developing a set of criteria for approval by the State Board of Education that school districts and public charter schools may use in developing local assessment options.

Using Work Samples to Assess Essential Skills for the Oregon Diploma

Essential Skills graduation requirements are determined based on when a student is first enrolled in grade 9, which is referred to as the cohort year. These requirements are applied to students earning either the regular or modified diploma. Students who entered grade 9 in the 2008-2009 school year (most of whom will graduate in 2012) are required to demonstrate proficiency in the Essential Skill of Reading. The remaining implementation timeline is described in the table below. Work samples are one assessment option that high school students may use to demonstrate they are proficient in the Essential Skills. Regarding demonstration of proficiency in the Essential Skills, districts must:

provide students with instruction in and multiple assessment opportunities to demonstrate proficiency in the Essential Skills for the purpose of earning a high school or modified diploma.

allow students to use assessment options adopted in a student’s 9th through 12th grade years.

allow students to use achievement standards adopted in their 9th through 12th grade years that are equal to or lower than the achievement standards approved as of March 1 of the students’ 8th grade year.

At the high school level, students may use work samples to fulfill both the local performance assessment and the Essential Skills requirements. The table below describes the achievement standard for work samples scored for the purpose of demonstrating proficiency in the Essential Skills with regard to conferring a high school diploma.

Appendix B: Cognitive Demand and Item Difficulty Distribution Goals

Oregon recognizes the importance of Cognitive Demand (Depth of Knowledge) as part of test specification. To that end, we are implementing a

strategy to overtly incorporate a test design process that includes the three dimensions of content, difficulty, and depth of knowledge.

The first step in the process is convening our content panels to ask for their determination as to the appropriate allocation of Cognitive Demand

(Depth of Knowledge), given the content standards.

The second is analyzing the gap between the Cognitive Demand (Depth of Knowledge) available in our current item pools against the

recommendations of the content panels.

The third step involves engaging item writers to write items to fill in the critical gaps. These items would then be reviewed through our

standard processes.

We anticipate being able to include Cognitive Demand (Depth of Knowledge) as an explicit part of the test specifications in the near future. The three

Cognitive Demand (Depth of Knowledge) levels to be addressed in Mathematics are:

Recall: includes the recall of information such as a fact, definition, term, or implementing a simple procedure. In mathematics, a one-

step, well defined and straight-forward algorithmic procedure should be included at this lowest level.

Skill/Concept: includes the engagement of some mental processing beyond a habitual response. A Level 2 assessment item requires

students to make some decisions as to how to approach the problem or activity, whereas Level 1 requires students to demonstrate a rote

response, follow a set procedure, or perform a clearly defined series of steps.

Strategic Thinking: includes tasks which require reasoning, planning, using evidence, explaining their thinking or to making

conjectures, and a higher level of thinking than the previous two levels. The cognitive demands are complex and abstract. The

complexity does not result from the fact that there are multiple answers but because the task requires more demanding reasoning.

Cognitive Complexity/Depth of Knowledge Levels for Mathematics RECALL includes the recall of information such as a fact, definition, term, or implementing a simple procedure. In mathematics, a one-step,

well defined and straight-forward algorithmic procedure should be included at this lowest level. Other key works that signify Recall include

“identify,” “recall,” and “measure.” Verbs such as “describe” and “explain” could be classified at different levels, depending on what is to be

described and explained. Some examples that represent, but do not constitute all of, Recall performance, are:

Perform a simple algorithm.

Recall a fact, term, formula, or property.

Identify an example of a concept.

Calculate a sum, difference, product, or quotient.

Identify an equivalent representation.

Evaluate an expression in an equation or formula for a given

variable. (Here, evaluate is used in the context of substitution

and calculation with open expressions.)

Answer (Solve) a routine one-step word problem

Draw or measure simple geometric figures.

Read or select information from a graph, table, or figure.

SKILL/CONCEPT includes the engagement of some mental processing beyond a habitual response. A Skill/Concept assessment item requires

students to make some decisions as to how to approach the problem or activity, whereas Recall requires students to demonstrate a rote response,

follow a set procedure, or perform a clearly defined series of steps. Key words that generally distinguish a Skill/Concept item include “classify,”

“organize,” “estimate,” and “observe.” These actions imply more than one step. For example, to compare data requires first identifying

characteristics of objects or phenomena and then grouping or ordering the objects. Some action verbs, such as “explain,” “describe,” or “interpret,”

could be classified at different levels depending on the object of the action. For example, interpreting information from a simple graph or reading

information from the graph would be at Skill/Concept. Interpreting information from a complex graph that requires some decisions on what features

of the graph need to be considered and how information from the graph can be aggregated is at Strategic Thinking. Skill/Concept activities are not

limited only to number skills, but may involve visualization skills and probability skills. Some examples that represent, but do not constitute all of,

Skill/Concept performance, are:

Describe non-trivial patterns.

Apply experimental procedures.

Observe and collect data.

Classify, organize and compare data.

Organize and display data in tables, graphs, and charts.

Represent a situation mathematically in more than one way.

Solve a word problem requiring multiple steps.

Compare figures or statements.

Interpret a visual representation.

Extend a pattern.

Use information from a graph, table, or figure to solve a

problem requiring multiple steps.

Formulate a routine problem, given data and conditions.

Interpret a simple argument.

STRATEGIC THINKING requires reasoning, planning, using evidence, and a higher level of thinking than the previous two levels. In most

instances, requiring students to explain their thinking is at Strategic Thinking. Activities that require students to make conjectures are also at this

level. The cognitive demands at Strategic Thinking are complex and abstract. The complexity does not result from the fact that there are multiple

answers but because the task requires more demanding reasoning. An activity that has more than one possible answer and requires students to justify

the response they give would most likely be at Strategic Thinking. Some examples that represent, but do not constitute all of, Strategic Thinking

performance, are:

Draw conclusions from observations.

Cite evidence and develop a logical argument for concepts.

Explain phenomena in terms of concepts.

Decide which concepts to apply in order to solve a complex

problem.

Describe how different representations can be used for different

purposes.

Perform or adapt a complex procedure having multiple steps

and multiple decision points.

Identify similarities and differences between procedures and

concepts.

Formulate an original problem, given a situation.

Solve a non-routine or novel problem.

Solve a problem in more than one way.

Explain and justify a solution to a problem.

Describe, compare, and contrast solution methods.

Formulate a mathematical model for a complex situation.

Appraise the assumptions made in a mathematical model.

Critique or develop a deductive argument.

Develop a mathematical justification.

EXTENDED THINKING involves high cognitive demands and complex reasoning, planning, developing and thinking, most likely over an

extended period of time. Extended thinking is not considered to be assessable through the OAKS multiple choice items, but could be assessed through

appropriate Work Sample or Local Performance Assessment tasks. The extended time period is not a distinguishing factor if the required work is only

repetitive and does not require apply significant conceptual understanding and higher-order thinking. For example, if a student has to take the water

temperature from a river each day for a month and then construct a graph, this would be classified as a Skill/Concept. However, if the student is to

conduct a river study that requires taking into consideration a number of variables, this would be at Extended Thinking. At Extended Thinking, the

cognitive demands of the task should be high and the work should be very complex. Students should be required to make several connections – relate

ideas within the content area or among content areas – and have to select one approach among many alternative on how the situation should be solved,

in order to be at his highest level. Some examples that represent, but do not constitute all of, Extended Thinking performance, are:

Design and conduct experiments and project

Develop and prove conjectures

Connect a finding to related concepts and phenomena

Synthesize ideas into a new concept.

Critique experimental designs

APPENDIX C: ITEM DEVELOPMENT PROCESS

Oregon’s item development process is consistent with industry

practice and takes approximately two years, including writing,

reviewing, and field-testing new items. Just as the development

of Oregon’s content and performance standards is an open,

consensus-driven process, the development of test items and

prompts to measure those constructs is grounded in a similar

philosophy.

Item Writing

For the Knowledge and Skills (multiple-choice) tests and the

Writing Performance Assessment, most item writing takes

place during either onsite, remote and/or online item writing

workshops, in which Oregon teachers across the five main

content areas write and review items. The process remains the

same regardless of workshop format.

Item writers are typically Oregon teachers who have received

training in item construction, are familiar with test

specifications, and have demonstrated skill in writing items

that pass content and sensitivity panel review. Item writers

receive professional development compensation for their time

and travel expenses. Among other security precautions, ODE

requires item writers to sign confidentiality forms assuring that

they will work with the items in a secure manner.

All items are written to measure specific subdomains of the

content standards at a variety of specified levels of cognitive

complexity. Cognitive complexity is represented by the

following classification, developed from Bloom’s (1956)

educational taxonomy:1

Recall: Recall, label, or locate information; define or

describe facts or processes.

Skill/Concept (Basic Application): Use information or

conceptual knowledge, often requiring two or more steps;

summarize, classify, or explain information or processes;

make predictions or generalizations; solve problems.

Strategic thinking: Analyze, critique, compare or

contrast; create new information; or organize presented

information.

Extended thinking: Make connections and extensions

(exclusively assessed in the Writing Performance

Assessment and local performance assessments).

During the item writing workshop, writers draft items,

document rationale of distracters, and conduct peer reviews of

each other’s items. Examples of items are provided, and

facilitators provide process guidance and additional review.

Writers and reviewers evaluate the strength and clarity of the

match between the drafted item and the standard it measures.

All issues are worked out or solved multiple times by multiple

reviewers who verify that distracters are plausible, that answers

are correct, and that each item has only a single correct answer.

Krathwohl, D. R. (1956). Taxonomy of educational objectives: Handbook I:

Cognitive domain. New York: David McKay.

Figure 1.

Sample Oregon Item Writing Form

Following item writing workshops, items are entered into the

Item Tracking System (ITS). Oregon’s original graphics are

initially entered into the ODE’s Comprehensive Item

Management System (CIMS) and then transferred to ITS.

Within ITS and CIMS, each item is given a unique item

identification number to facilitate the monitoring and tracking

of changes to and usage of the item throughout the review

process and each item’s history. ITS provides authorized users

with access to each item’s alignment and attributes, field-test

results and use, response rationales, and previous versions.

Although item writing workshops may still occur annually,

ODE has recently moved toward distributed item writing in

which consistently strong item writers author additional items

throughout the year. Items still go through the review process

previously described. Item writers are trained on the use of

secure item entry using ITS, and graphic drafts are scanned by

the item writers and securely transmitted to ODE.

Committee/Panel Review

ODE convenes a series of advisory groups to advise ODE both

on assessment-related policy and on item development. ODE

seeks to ensure that membership on these advisory groups

reflects the demographics of Oregon’s student population. Each

advisory group has approximately 15–35 members who serve

three-year terms with one-third of the members rotating out

each year and being replaced by new representatives. The

following table describes the structure of these groups.

Source: http://www.ode.state.or.us/teachlearn/testing/dev/panels/structurecapanels.doc

Panel members commit up to 6 school days of service with an

additional 3 or 4 days during the summer. However, panels will

be convened remotely rather than in person as secure

technology improvements allow distributed work. Although

committee members on district contracts are not compensated

for their service, they do receive travel reimbursem*nt for

committee travel of more than 70 miles, and substitute teachers

are provided for service during the school year. When

classroom teacher members work for ODE during non-contract

time, they are compensated at an hourly wage as temporary

employees

The Assessment Policy Advisory Committee consists of

representatives from Oregon school districts, schools, and

ESDs who are knowledgeable about assessment-related issues.

The purpose of the Committee is to advise ODE on both the

procedural and policy implications of Oregon’s assessment

system, as well as the feasibility of proposed improvements to

Oregon’s assessment system. Committee members provide

input regarding the various elements of the state assessment

system such as educational technology, electronic reporting,

operational assessment issues, and test administration.

In addition to seeking advice on assessment-related policy,

ODE requires that all items generated for use on Oregon

statewide assessments must pass a series of rigorous reviews

before they can be used in field and operational tests. All items

go through both a content and a sensitivity review as part of the

Appendix C Mathematics, Grade 8

Mathematics Test Specifications and Test Blueprints

C-3 Oregon Department of Education Office of Assessment and Information Services

item development process; only those items that measure the

grade-level expectations and meet both overall quality and

sensitivity criteria are carried forward to the field-test stage.

ODE Content and Assessment Panels exist for each of the

content areas for which statewide tests are given:

English/Language Arts (this panel reviews Writing and

Reading/Literature assessment items), Mathematics, Science,

Social Sciences, and English Language Proficiency.

Most members of these panels are classroom teachers, with

some representation from higher education, district curriculum

and assessment personnel, and related businesses. Criteria for

panel selection include the following:

Knowledge of Oregon’s content standards and

expertise in the subject area and its eligible content

Teaching experience at the grade level or benchmark

to which the individual will be assigned

Geographical location to ensure that all regions of

Oregon are represented

Gender and ethnic diversity to ensure that the panel

represents the diversity of Oregon’s student population

Current item writers are not allowed to serve on item review

committees. However, in some cases, content and assessment

panel experts may be utilized as item writing facilitators.

Items are accepted, rejected, or modified by the Content and

Assessment Panel to make sure they represent the constructs

embodied in grade-specific content standards and test

specifications. In addition to judgments of content relevance,

the panels appraise the technical quality of items, looking for

items that are free from such flaws as (a) inappropriate

readability level, (b) ambiguity, (c) incorrectly keyed answers

and distracters, (d) unclear instructions, and (e) factual

inaccuracy. The panels for each content area use the following

review process:

1. Three content panel members review each item

independently and complete an Item Review Form

(IRF) (figure 1) using a pre-assigned reviewer ID.

2. Then, the three content panel members review the item

collectively, and item reviewers make a

recommendation for each item on the IRF to either (a)

accept the item as written, (b) accept the item with

revisions, or (c) reject the item (sometimes an alternate

question is offered that entails a simple revision).

3. When all three reviewers agree that an item should be

accepted or rejected, no further discussion is needed. If

one or more of the reviewers feel that an item should be

revised, then they attempt to reach a consensus and

produce a “master copy” of their recommendation. The

same is true if one or two of the reviewers reject an

item that another reviewer finds acceptable with or

without revisions.

4. In most cases, recommendations are followed and

revisions are made, or items are eliminated. The ODE

assessment specialist can override the recommendation,

but this occurs rarely and only for compelling reasons.

Appendix C Mathematics, Grade 8

Figure 2.

Sample Oregon Content and Assessment Panel Item

Review Form

The content panels perform specific checks on items to confirm

that:

the SRC and subcategory match.

the key is correct.

alternate valid interpretations making the distracters

correct do not exist.

the item is grade-level appropriate in content and reading

levels.

the item is of overall high quality (wording and

grammar, graphic quality, curricular importance, etc).

the identified level of difficulty (i.e., easy, medium,

hard) is correct.

Reading/Literature passages are appropriate in content

and reading levels. Science and Social Sciences stimuli

align to appropriate content and reading skills.

the level of cognitive complexity (i.e., recall,

skill/concept or strategic thinking) is appropriate to the

item and correctly identified.

Following review by the content panel, and according to panel

feedback, ODE assessment specialists edit and revise items in ITS

in preparation for review by the Sensitivity Panel.

All items that pass review by the content specialist are next

presented to the sensitivity panel. The sensitivity panel reviews

convenes day-long meetings, four to six times a year. The panel

reviews items from all grade levels and content areas for bias,

controversial content, and overly emotional issues.

Appendix C Mathematics, Grade 8

Mathematics Test Specifications and Test Blueprints

C-5 Oregon Department of Education Office of Assessment and Information Services

In general, the sensitivity panel ensures that items:

present racial, ethnic, and cultural groups in a positive

light.

do not contain controversial, offensive, or potentially

upsetting content.

avoid content familiar only to specific groups of

students because of race or ethnicity, class, or

geographic location.

aid in the elimination of stereotypes.

avoid words or phrases that have multiple meanings.

Following the sensitivity panels and according to panel

feedback, ODE assessment specialists edit and revise items in

the ITS system.

EXPERT REVIEW

Next, ODE assessment specialists submit the new items for

review by experts that have experience in the roles of item

writer and content and assessment panel member. Expert

reviewers add an additional quality control check for the online

assessments. Experts have received extensive professional

development in ITS to review items in a web-preview format

providing the exact rendering provided in the online

assessments. Experts review each item and confirm that:

the key is correct.

alternate valid interpretations making the distracters

correct do not exist.

the item is grade-level appropriate in content and

reading levels.

the item is of overall high quality (wording and grammar,

graphic quality, curricular importance, etc).

Following the expert review in most cases, recommendations are

followed and revisions are made, or items are eliminated. The

ODE assessment specialist can override the recommendation, but

this occurs rarely and only for compelling reasons.

FIELD TESTING

Once the items have been reviewed by the content and assessment

panel, the sensitivity panel, and an expert reviewer, all

Mathematics, Reading/Literature, Science, and Social Sciences test

items are field tested. Field test items identified by the ODE

assessment specialists are embedded in the operational tests by

content area. As students take the operational tests, they also

respond to approximately 5-8 field test items embedded in the test.

ODE then receives data files of the student responses, which ODE

analyzes to determine whether the field test items are behaving as

expected. The ODE assessment specialists eliminate those items

which the data analysis indicate performed weakly. ODE

assessment staff calibrate the difficulty level for those items that

performed successfully in preparation for using the item

operationally.

TRANSLATION OF ITEMS TO SPANISH

Concurrent with the field testing of items in English, all

Mathematics, Science, and Social Sciences test items are

translated into Spanish. All required grade-level and benchmark-

level statewide tests for Mathematics and Science are offered in

English-Spanish tests. English-Spanish tests are also available for

Social Sciences. Stacked English-Spanish items are used on

electronic tests. Side-by-side English-Spanish and English-

Russian Paper/Pencil assessments are available in Mathematics

and Science.

Following translation by ODE’s translation vendor, the translated

items are reviewed by ODE’s Spanish- and Russian-speaking

experts to ensure that each item accurately conveys the intent of

the English text. While the procedure described below specifically

addresses Spanish translation, ODE follows a similar procedure

for translation of Paper/Pencil items into Russian.

The following linguistic guidelines are used by ODE’s translation

vendor and Spanish-speaking experts:

Students are expected to have subject knowledge and use

proper terminology/vocabulary for that subject. In other

words, what is expected from English-speaking students is

also expected from Spanish-speaking students.

ODE uses formal Spanish (usted, not tú) for test items and

includes proper verb conjugation.

ODE strives to use Global Spanish language that will be

interpreted and understood by all Spanish speakers from

anywhere in the world. Global Spanish language includes

words used worldwide by most Spanish speakers.

After the ODE Spanish reviewers complete a review of the

newly translated items, extensive research is conducted by a

small group of reviewers on any word that has not met group

consensus. Every attempt is made to choose the most correct

translation based upon grade level and cultural relevance. A variety

of resources are used for selecting the proper translated words

including: dictionaries from Mexico, South America and Spain

(e.g. Diccionario Hispanoamericano de Dudas, Diccionario de

Matemáticas), and ODE’s list of translated terms for Science at

http://www.ode.state.or.us/search/page/?id=517

and for Mathematics at

http://www.ode.state.or.us/search/page/?id=500 .

ADDITIONAL EXPERT REVIEW OF ITEMS

On an annual basis, ODE assessment specialists review items from

the field test pool for inclusion within the operational test. This

level of review acts as an additional quality control for the online

assessments. In addition, whenever ODE transitions to a different

test delivery system, ODE submits all of its Reading/Literature,

Mathematics, Science, and Social Sciences items for an additional

level of expert review to ensure that all items appear consistently

from year to year when presented to students.

ITEM USE AND RELEASE

Approximately every three years, ODE releases one sample test for

each content area and grade-level and benchmark-level comprised

of items used on previous test forms. These items are no longer

secure and are taken out of the pool of eligible test items.

Released items are provided in the form of practice tests. Practice

tests for Reading/Literature, Mathematics, Social Sciences, and

Science are available on ODE’s Website at

http://www.ode.state.or.us/search/page/?id=1222 .

Mathematics Problem Solving Official Scoring Guide

(http://www.ode.state.or.us/search/page/?=32)

The Mathematics Problem Solving Official Scoring Guide was adopted by the State Board of Education in May 2011 for scoring work

samples beginning with the 2011-2012 school year. This scoring guide reflects significant efforts of Oregon educators working to capture

the essentials of problem solving, based on the following:

Over-arching statement in the Mathematics Content Standards for Kindergarten through Grade 8 and High School that it is essential

that these standards be addressed in instructional contexts that promote problem solving, reasoning, communication, making

connections, designing and analyzing representations, and reflecting on solutions.

(http://www.ode.state.or.us/teachlearn/real/standards/sbd.aspx)

Essential Skill Apply Mathematics in a Variety of Settings

This skill includes all of the following:

o Interpret a situation and apply workable mathematical concepts and strategies, using appropriate technologies where applicable.

o Produce evidence, such as graphs, data, or mathematical models, to obtain and verify a solution.

o Communicate and defend the verified process and solution, using pictures, symbols, models, narrative or other methods.

(http://www.ode.state.or.us/teachlearn/certificates/diploma/essential-skills-definitions.pdf)

Standards for Mathematical Practice, from the Common Core State Standards (2010)

(http://www.corestandards.org/the-standards/mathematics/introduction/standards-for-mathematical-practice)

This scoring guide reflects input by the Oregon Council of Teachers of Mathematics (OCTM), Oregon Mathematics Specialists, and

ODE’s mathematics content panel during 2009-10, and at the 2010 Oregon Math Leaders Conference.

The most recent version of the Mathematics Problem Solving Official Scoring Guide and other support documents may be accessed at

http://www.ode.state.or.us/search/page/?=2667.

Sample anchor papers, student versions, and other support materials are under development. Professional development on the new

scoring guide is was piloted in training sessions during the 2010-11 school year by the OCTM Professional Development Cadre and

extensive training opportunities are planned for the 2011-2012 school year. Refer to the Work Sample Resources web page for

Use of Formula and Conversion Sheets

The Formula and Conversion Sheets have been revised to reflect the content in the 2007 Grades 3-8 and 2009 High School Standards.

They are reorganized to be used in Grade 3-5, Grades 6-8, and in High School. While all students may have access to any of the

sheets, these show the information appropriate to the grade levels. Note that grade 3 standards do not necessitate any formulas or

conversion factors, based on the standards. Also, variables are not introduced until grade 6, so the formulas for grades 4-6 are stated

in words. Grade 6 standards do not necessitate any formulas other than those needed for grades 4 and 5, since grade 6 has no new

geometry content, however, in grade 6, students may be using variables, so students in grade 6 may prefer either the formula sheet for

grades 3-5 or the one for grades 6-8.

All Formula and Conversion Sheets in English and Spanish are available at http://www.ode.state.or.us/search/page/?=2346

The Formula and Conversion Sheets may be used during classroom instruction at any time.
