Analysis of three representations in problem solving on additional relativistic velocities

Abstract

In this study is an analysis of three representations in problem-solving on additional relativistic velocities. This research method is descriptive quantitative. Purposive sampling is a technique to get sampling in this research. The sample in this study are students who have studied relativistic speed on three different islands, namely Java Island, Kalimantan, and Papua. The students can be problem-solving in three forms of representation: Verbal (V), Diagrams (D), and Mathematics (M). Three representation skills take some description about representation skills student of physics education. It found that students had difficulty 73% in problem-solving in the form of representation V, 86% difficulties in problem-solving in the form of representation D, and 7% difficulty in problem-solving in the form of representation M. This study should also be implemented on different materials and colleges.
