The development of test instruments to support students’ ability on mathematical learning evaluation course

Abstract

The purpose of this study was to develop mathematics test instruments for secondary school students that is valid, reliable, a good discrimination, and a good level of difficulty. This research was a research and development using the stages of instrument development, namely: (1) compiling test instrument specifications, (2) writing test instruments, (3) examining test instruments, (4) conducting test, (5) analyzing items, (6) fixing the test. The instruments used in this study consisted of expert validation sheets with index Aiken analyze and student response sheets. The subject in this study was thirty secondary students of the Mathematics Education Study Program, Faculty of Education, University of Bengkulu who took mathematical learning evaluation course. The results of the research showed that in developing of the instruments obtained were 160 items of multiple choice test for seventh and eighth grade. The results of the analysis showed that all test instruments were reliable with a high category, good discrimination, and easy to medium difficulty level. The results of student responses in preparing test instruments showed high criteria with an average score 49.70.
