ObjectivesObjectives

•Overview of Curriculum-Based Measurement (CBM)

•Review CBM measures in: math, spelling, and writing (including writing IEP goals and objectives)

•Cover criteria for progress monitoring in math and spelling

•Provide information on where to obtain measures for math, spelling, and writing

3

CBM ResearchCBM Research

•CBM research has been conducted over the past 25+ years

•Research has demonstrated that when teachers use CBM for instructional decision making: Students learn more Teacher decision making improves Students are more aware of their

performance

Different Types of CBADifferent Types of CBA

Salient Features ofSalient Features ofMastery MeasurementMastery Measurement

• Curriculum is broken down into specific subskills or short-term instructional objectives

• Assess specific skill that is being taughtExample Multidigit addition, with regrouping

• Skills usually assessed using teacher-made tests or tests in curriculum

6

Fourth Grade Math Computation Curriculum

1. Multidigit addition with regrouping

2. Multidigit subtraction with regrouping

3. Multiplication facts, factors to 9

4. Multiply 2-digit numbers by a 1-digit number


6. Division facts, divisors to 9

7. Divide 2-digit numbers by a 1-digit number


9. Add/subtract simple fractions, like denominators

10.Add/subtract whole number and mixed number

Downsides to Downsides to Mastery MeasurementMastery Measurement

• Skill Hierarchies

• Teacher-Made Tests Reliability & Validity are unknown

• Retention & generalization of skills are not usually measured

• Measurement of Short-Term Instructional Objectives

• Measurement shifts occur making it difficult to monitor overall progress because:

1. different skills are measured at different points in time

2. different skills are not of equal difficulty and do not represent equal curriculum units

Most Forms of Classroom Most Forms of Classroom Assessment Are MasteryAssessment Are Mastery

MeasurementMeasurementCBM is NOT

Mastery Measurement

CBM is a General Outcome Measure

Salient Features of Salient Features of General Outcome MeasurementGeneral Outcome Measurement

•General domains, not subskills Keeps global curriculum outcomes

intact and uses long-term goals

•Makes no assumptions about instructional hierarchy for determining measurement (i.e., CBM fits with any instructional approach) No measurement shifts

19

Salient Features of Salient Features of General Outcome Measurement (cont)General Outcome Measurement (cont)

•Incorporates automatic tests of retention and generalization Measurement of Long-Term Curricular

performance on the long-term goal Reliability & validity can be determined

20

Downsides to Downsides to General Outcome MeasurementGeneral Outcome Measurement

•Often lacks information on specific subskills If interested in identifying specific

skills to teach, GOM not appropriate Need to use a diagnostic measure

•Fidelity of implementation is important

• Student(s) are given a sheet of math problems and pencil

• Student(s) complete as many math problems as they can in 2 minutes

• At the end of 2 minutes the number of correctly written digits is counted

Math scoring criteriaMath scoring criteria• If the answer is correct, the student

earns the score equivalent to the number of correct digits written using the “longest method” taught to solve the problem, even if the work is not shown

• If a problem has been crossed out, credit is given for the correct digits written

• If the problem has not been completed, credit is earned for any correct digits written

Total Words Written (TWW)Total Words Written (TWW)

•The total number of words written regardless of spelling or context.

•Abbreviations: Commonly used abbreviations are counted as words

•Hyphenated Words: Each morpheme separated by a hyphen(s) is counted

as an individual word if it can stand alone.

•Story Titles Words written in the title are counted as words written

51

Words Spelled CorrectlyWords Spelled Correctly

•A word is spelled correctly if it can

stand alone in the English language

•Contextual clarity is not an issue

53

Correct Writing Sequences Correct Writing Sequences (CWS)(CWS)

•Two adjacent writing units (word/word

or word/punctuation) that are

acceptable within the context of what is
