Instrument design of remedy test assisted by multiple representations using computer-based test model on redox materials

Abstract

This study discusses the mastery of students' learning outcomes who join the remedy program using the test instruments based on multiple representations arranged in Computer-based Test (CBT) model.CBT used in this study using the Beesmart application. The multiple representations studied include three levels of representation, namely macroscopic, microscopic, and symbolic on redox learning. Research subjects are 100 students of X grade of natural science class in MAN 2 Semarang (Islamic senior high school 2 Semarang). The test instrument was validated by 3 instrument experts with a mean score of 38.7 from a maximum score of 44, and 2 media experts obtained a mean score of 24.5 with a maximum score of 32 with a decent category tested. The level of completeness of student learning outcomes who join the remedy program is calculated using the percentage of mastery. The results showed that the level of ability of students' learning outcomes that followed remedy was 83%.
