Aynı Özelliği Ölçmeye Yönelik Olarak Hazırlanan Çoktan Seçmeli ve Karma Testlerin Psikometrik Özelliklerinin Karşılaştırılması
Özet
This research was conducted in two forms: multiple choise test and mixed test. This study was carried out to determine whether there is a significant difference between the item difficulty indices, item discrimination indices, test averages, test reliabilities and response times obtained by applying the “8th Grade Mathematics Achievement Test” and “8th Grade Science Achievement Test" online in a computer environment. The data was collected from 173 eighth grade students. As a result of the research, a significant difference was determined in favor of form multiple choice test in both tests between the item difficulty indexes of multiple-choice test items and test items requiring multiple choice, true/false, matching and short answers with more than one correct answer and form multiple choice test was found to be easier. No significant difference was found for the item discrimination power indices obtained from the multiple choice test and mixed test forms of the mathematics and science achievement tests. While there was no significant difference between the forms of the mathematics achievement test in terms of test reliability, a significant difference was found at the p <.05 level in favor of form multiple choice test in the science achievement test. While there was no significant difference in the response times between the forms of the mathematics achievement test, a significant difference was found at the level of p <.01 in favor of form mixed test in the science achievement test.
