Instructional Uses of Test Results Interpreting Item-Level Reports
Iowa Assessments Provide Teacher with Important information to use in your instructional decision-making Information that is intended to supplement your observations and classroom assessment data Information to help teachers plan to accommodate classroom and individual student needs
Todays Session Procedures for the review of test booklets Class Item Response Record Class Item Analysis
Review of Test Booklets Provided for: – Review of item-level reports – Support of data analysis and interpretation Supported by: – Assurances language for proper and ethical test administration and use (Iowa Department of Education) – Iowa Testing Programs Online Tools
Class Item Response Record Assists teachers in the diagnosis of learning difficulties within a test area Used to identify students who are not completing a test Used by teachers to identify areas where a large part of the class is having difficulty with the same concept – Common misconception – Scope and sequence issue
Class Item Response Record In the body of the chart – Numbers are Percent Correct – Letters are the incorrect response marked by that student – Blanks are correct responses
Average Percent Correct scores for the nation, system, and class can be used to compare: Class to Nation System to Nation Class to System Students to the whole Class Average percent correct scores for the entire Reading test. The class did as well as the system and the nation Average percent correct scores for Reading subtests. In general, the class performed similarly to the system and slightly below the nation
This report can be used to help detect strengths and weaknesses of Individual students The class as a whole These students answered All Central ideas & their support items incorrectly The same on Synthesizing/summarizing items Correctly on all Connecting/extending ideas items This group of students may need more help grasping the first two concepts than the third.
Students either answered this item correctly or they chose incorrect option C. Further information about the item would allow the teacher to decide the best way to remedy this shared misunderstanding.
This student appears to be struggling with the Reading content in general. However, He answered only one Understand stated information item incorrectly. He answered all Connecting/extending ideas items correctly. This information is useful because it shows which areas he is more successful in, allowing the teacher to decide how to best address the other areas he is struggling with. This student appears to be performing well on the Reading content in general. His incorrect answers to Authors Craft items seem to be similar to other students incorrect responses. Perhaps these patterns indicate a misunderstanding shared among students. More information about the content covered by these items could help the teacher decide how to address such confusion.
Class Item Analysis Provides a deeper diagnostic review of performance The items that are most difficult for a class can be identified Analysis of the most difficult items may be beneficial in understanding why test performance was low
This report allows for comparisons between the Class Building System Nation This can be useful for identifying skills that need extra attention or improvement, as well as skill areas that are being understood well. These show the difference between the class average and the national average for each skill. A + or – indicates the difference is larger than 20 points. These graphs are useful to see stronger and weaker skill areas at a glance.
On average, the class performed lower than the nation on items covering Central ideas and their support. However, in general, the class performed similarly to the building and the system. On items 9 and 12, the class did better than the building and system. The graphs illustrate that this class performed similarly or much better than the nation on Understand stated information items.
