Developing Test Instruments for Measurement of Students' High-Order Thinking Skill on Mathematics in Junior High School in Makassar

Abstract

This study aims to determine the procedure and to assess the quality of test instrument development to measure students' high-order thinking skill on mathematics in Junior High School in Makassar. The type of this research is a Research and Development with formative research model through 4 phases: preliminary, self-evaluation, prototyping and field test. The research subjects were the students of class VIII Junior High School in Makassar. The results of the instrument validity test was valid because in CVI (Content Validity Index) and CVR (Content Validity Ratio) the total average score was 1 with category very appropriate or at the interval 0.68 - 1.00. The result of student response test is 68.5% on positive category because more than 50% students responded positively. The reliability test indicated that the total average score was 0.923 with very high category (reliable) because it was at the interval 0.80 < (x) total score ≤60. Therefore, it is concluded that the students' high-order thinking skill at Junior High School in Makassar Makassar was in sufficient category.
