1 28 Student Progress Monitoring & Data-Based Instruction in Special Education Graphing and Interpreting CBM Scores An overview (Sample presentation to present to students) How to Graph Scores Graphing student scores is vital. Graphs provide teachers with a straightforward way to: Review a student s progress. Monitor the appropriateness of student goals. Judge the adequacy of student progress. Compare and contrast successful and unsuccessful instructional aspects of a student s program. 2 1

2 How to Graph Scores Teachers can use computer graphing programs. Teachers can create their own graphs. A template can be created for student graphs. The same template can be used for every student in the classroom. Vertical axis shows the range of student scores. Horizontal axis shows the number of weeks. 3 How to Graph Scores 4 2

3 How to Graph Scores Student scores are plotted on the graph, and a line is drawn between the scores. 2 Digits Correct in 3 Minutes Weeks of Instruction How to Graph Scores How to create graphs in Microsoft Excel Ashley Ben Carter

Three options for making performance goals: End-of-year benchmarking Intra-individual framework National norms 8 4

5 How to Set Ambitious Goals End-of-year benchmarking: For typically developing students, a table of benchmarks can be used to find the CBM end-of-year performance goal. 9 How to Set Ambitious Goals Reading Grade Kindergarten First Second Third Fourth Fifth Sixth Benchmark 4 letter sounds per minute (CBM LSF) 6 words correct per minute (CBM WIF) words correct per minute (CBM PRF) 7 words correct per minute (CBM PRF) 1 words correct per minute (CBM PRF) 2 correct replacements per 2. minutes (CBM Maze 2 correct replacements per 2. minutes (CBM Maze 3 correct replacements per 2. minutes (CBM Maze) 1

Baseline rate is multiplied by 1.. Product is multiplied by the number of weeks until the end of the school year. Product is added to the student s baseline rate to produce end-of-year performance goal. 12 6

Multiply by weeks left: = 6.9.

A goal line is drawn between the median of the student s scores and the. 17 How to Set Ambitious Goals Drawing a goal-line: A goal-line is the desired path of measured behavior to reach the performance goal over time. Digits Correct in Minutes The is the end-of-the-year performance goal. A line is drawn from the median of the first three scores to the performance goal Weeks of Instruction 18 9

10 How to Set Ambitious Goals After drawing the goal-line, teachers continually monitor student graphs. After seven or eight CBM scores, teachers draw a trend-line to represent actual student progress. A trend-line is a line drawn in the data path to indicate the direction (trend) of the observed behavior. The goal-line and trend-line are compared. The trend-line is drawn using the Tukey method. 19 How to Set Ambitious Goals Tukey Method Graphed scores are divided into three fairly equal groups. Two vertical lines are drawn between the groups. In the first and third groups: Find the median data point. Mark with an on the median instructional week. Draw a line between the first group and third group. This line is the trend-line. 2 1

Programs create graphs and aid teachers with performance goals and instructional decisions. Various types are available for varying fees. Programs are listed in CBM manuals

13 How to Apply Decision Rules to Graphed Scores to Know When to Revise Programs and Increase Goals After trend-lines have been drawn, teachers use graphs to evaluate student progress and formulate instructional decisions. Standard decision rules help with this process. 2 How to Apply Decision Rules to Graphed Scores to Know When to Revise Programs and Increase Goals If at least 3 weeks of instruction have occurred and at least six data points have been collected, examine the four most recent consecutive points: If all four most recent scores fall above the goal-line, then the end-of-year performance goal needs to be increased. If all four most recent scores fall below the goal-line, then the student's instructional program needs to be revised. If the four most recent scores fall both above and below the goal-line, then continue collecting data (until the four-point rule can be used or a trend-line can be drawn)

If the trend-line is flatter than the goal line, then the student s instructional program needs to be revised. If the trend-line and goal-line are fairly equal, then no changes need to be made. 29 How to Apply Decision Rules to Graphed Scores to Know When to Revise Programs and Increase Goals 3 Digits Correct in 7 Minutes Trend-line Goal-line Weeks of Instruction 3 1

Schools must determine measure(s) for AYP evaluation and the criterion for deeming an individual student proficient. CBM can be used to fulfill the AYP evaluation in mathematics

18 How to Use Curriculum-Based Measurement Data to Accomplish Teacher and School Accountability for Formulating Policy Directed at Improving School Outcomes Using mathematics CBM: Schools can assess students to identify the number of initial students who meet benchmarks (initial proficiency). The discrepancy between initial proficiency and universal proficiency is calculated. 3 How to Use Curriculum-Based Measurement Data to Accomplish Teacher and School Accountability for Formulating Policy Directed at Improving School Outcomes Using mathematics CBM (continued): The discrepancy is divided by the number of years before the deadline. This calculation provides the number of additional students who must meet benchmarks each year

19 How to Use Curriculum-Based Measurement Data to Accomplish Teacher and School Accountability for Formulating Policy Directed at Improving School Outcomes Advantages of using CBM for AYP: Measures are simple and easy to administer. Training is quick and reliable. Entire student body can be measured efficiently and frequently. Routine testing allows schools to track progress during school year. 37 How to Use Curriculum-Based Measurement Data to Accomplish Teacher and School Accountability for Formulating Policy Directed at Improving School Outcomes Across-Year School Progress Number of Students Meeting CBM Benchmarks (27) End of School Year (498) 38 19

24 How to Use Progress Monitoring to Identify Non- Responders Within a Response-to-Intervention Framework to Identify Disability Traditional assessment for identifying students with learning disabilities relies on intelligence and achievement tests. Alternative framework is conceptualized as nonresponsiveness to otherwise effective instruction. Dual-discrepancy: Student performs below level of classmates. Student s learning rate is below that of his or her classmates. 47 How to Use Progress Monitoring to Identify Non- Responders Within a Response-to-Intervention Framework to Identify Disability All students do not achieve the same degree of mathematics competence. Just because mathematics growth is low, the student doesn t automatically receive special education services. If the learning rate is similar to that of the other students, then the student is profiting from the regular education environment

25 How to Use Progress Monitoring to Identify Non- Responders Within a Response-to-Intervention Framework to Identify Disability If a low-performing student is not demonstrating growth where other students are thriving, then special intervention should be considered. Alternative instructional methods must be tested to address the mismatch between the student s learning requirements and the requirements in a conventional instructional program. 49 Case Study: Alexis 3 2 Digits Correct in 2 Minutes Alexis s trend-line Alexis s goal-line Weeks of Instruction 2
