Implementation of Matrix Determinant Teaching Module in Two-Loop Closed Electrical Circuit to Improve High School Students' Physics Learning Outcomes

Abstract

The closed two-loop electrical circuit teaching module in schools is incomplete, the language is difficult to understand, the display is not attractive, and uses substitution-elimination with long stages. This study aims to improve the physics learning outcomes of high school students, as well as to determine the responses of teachers and students through a teaching module containing the matrix determinant method. This experimental research is in the form of a quantitative descriptive approach and a One Group Pretest-Posttest design. The research sample was 36 students of XII MIPA 4 and 3 physics teachers of SMAN 2 Jember. Data analysis used the N-Gain test (score) and response (percentage). The results showed that the implementation of the teaching module improved student learning outcomes with an N-Gain score of 0.82 in the high category. The teaching module received a positive response with a percentage of 93.06% from teachers and 88.39% from students in the very positive category. Thus, the implementation of the matrix determinant teaching module in a closed two-loop electrical circuit can improve the physics learning outcomes of high school students and receive a very positive response from physics teachers and students.
