MEASURING STUDENTS’ PROBLEM-SOLVING SKILLS ON DIRECT CURRENT CIRCUITS WITH MULTIPLE REPRESENTATIONS

Abstract

Purpose of study: This study aims to measure the level of students' problem-solving skills, using assessment instruments in the form of multiple-choice tests based on the multiple representation approach on DC electrical circuits.
 Methodology: This research is a quantitative descriptive involving 46 students of physics education. Students are asked to solve the problem of DC electrical circuits on 12 multiple choice questions with open reasons, involving verbal, mathematical, and picture representations. Data were analyzed by determining means and standard deviations.
 Main findings: The results of the study showed that there were 3 levels of students' problem-solving skills, namely 7 (15%) students in the high category, 22 (48%) students in the medium category and 17 (37%) students in the low category.
 Applications of this study: The implication of this research is to continuously develop assessment instruments based on multiple representations in the form of various types of tests, to help students improve their conceptual understanding, so students can solve physics problems correctly.
 The novelty of this study: Researchers explain the right way to solve physics problems, 1) students are trained to focus on identifying problems, 2) students are accustomed to planning solutions using a clear approach, to build an understanding of concepts, 3) students are directed to solve problems accordingly with understanding the concepts they have built.
