Analysis of higher order thinking skills instrument test for pre-service biology teachers based on marine ecology toward sustainable development

Abstract

This research used quantitative descriptive approach. It aims to analysis the quality of instruments test include validity, reliability, difficulty level and index of determinant to develop tests of critical thinking skills and creative thinking skills of prospective pre-service biology teachers on marine ecology theory. The test used instrument consisted of 2 type namely question descriptions and two tier multiple choice. There were two test of validation, namely content validation and empirical validation. The results of content validation concluded the question tests that feasible to be used with improvements. The results of empirical validation show that the ten items are valid question descriptions category and two invalid categorized questions. Where as instrument test twenty-three of two tier multiple choice valid in categories and four invalid categorical questions. Question descriptions instrument test used reliability analysis using Cronbach Alpha r11 = 0.73 (high). Instrument test two tier multiple choice used KR-20 r11 = 0.83 (very high), therefore the instruments test made are suitable for implementation in marine ecology. The average value of high order thinking skills for the question descriptions instrument test achieved by students was 26, while the two tier multiple choices instrument test 28. The highest value of the description questions instrument test achieved by students is 56 and the lowest score is 3. The highest value of two tier multiple choice questions instrument test achieved by students is 56 and the lowest score is 11. It shows that the ability of high order thinking skills of students is still lacking.
