DETERMINING MATHEMATICAL ITEM CHARACTERISTICS CORRESPONDING WITH ITEM RESPONSE THEORY ITEM INFORMATION CURVES
Page: 80
Tests in underergduate mathematics courses are generally high stakes, and yet have low reliability The current study aims to increase the reliability of such exams by studying the qualities of test items that determine the ability of the item to contribute, to the information of the test. Using q three parameter item response theory model, 695 items contained in'25 different tesis for 5 different first-year undergraduate mathematics courses have been gnalyzed to determine the abjlity of each item 10 contribute to the test's reliability. During the conference presentation, the speakers with m the participants regarding the types of qualities of thesé items that 'may contribiyfe to their information inex. These qualities may include cognitiv mathematical content, linguistic, or other descriptions.
