Abstract

The purpose of this study was to develop a diagnostic test of students' difficulties in the matter of integer and fraction operations through the approach of strength and weakness profiles. The instrument was developed using test development procedures consisting of (1) preparing the test specification, (2), writing the test, (3) reviewing the test, (4) implementing the test trial, (5) analyzing the test items, (6) improving the test, (7) assembling the test, (8) implementing the test, and (9) interpreting the test. The subject of this research is 47 students of junior high school grade 7 in Tarakan City. The result showed that the developed diagnostic test fulfills the valid criteria based on Aiken index; it obtained 0.80 with a reliability coefficient of 0.749. From 13 items developed, there are 10 items that are feasible and valid to be used. Item discrimination index of items test developed is in the range of 0.30 to 0.5 and items difficulty index is in the range of 0.30 to 0.70. The result of the implementation indicates that the test is able to describe students' difficulties in the matter of integer and fraction operations.
