Investigasi Kesalahan Siswa Menyelesaikan Soal Rangkaian Listrik 2-Loop dengan Aturan Cramer Berbantuan Metode Sarrus

Abstract

The 21st century signifies significant changes in education through the integration of technology and the enhancement of students' skills through various learning activities. Physics education, as a subject applying technology, particularly in the domain of electricity, poses challenges, especially in the topic of closed 2-loop electric circuits. This research aims to investigate student errors in solving problems related to these circuits. This study adopts a quantitative descriptive research design. The research findings discussed in this study present descriptive data on student errors categorized into four types: conceptual errors, data usage errors, strategy errors, and calculation errors. The conclusion drawn from this research highlights students' errors in solving simple 2-loop DC electric circuit problems using Cramer's rule assisted by the Sarrus method. The study, conducted descriptively following an assessment rubric, categorizes student errors into four types: conceptual errors 24%, data usage errors 5.33%, strategy errors 21.33%, and calculation errors 22.66%.
