Item Analysis Appropriate for Domain-Referenced Classroom Testing. (Project Technical Report Number 1)
REPORT

Abstract

Item analysis procedures appropriate for domain-referenced classroom testing are described. A conceptual framework within which item statistics can be considered and promising statistics in light of this framework are presented. The sampling fluctuations of the more promising item statistics for sample sizes comparable to the typical classroom size are described. Several statistical indices are recommended for use in an item analysis package programmed for an Apple II Plus microcomputer. The primary purposes of an item analysis of classroom tests are to inform the teacher about strengths and weaknesses of the class in relation to skills measured by test items, as well as to determine which items need to be replaced or revised. A secondary purpose of item analysis is selection of items from an item bank to improve the utility of a test for specific purposes. Several statistical indices are reviewed and classified as basic, recommended, or not recommended. (DWH)
