Learning Media PhET Laboratory to Improve Understanding of Mathematical Concepts: Classroom Action Research

Abstract

The use of technology in the context of education has become an urgent need to improve the effectiveness of learning in primary schools. The study aims to evaluate the impact of PhET (Physics Education Technology) media use on the understanding of mathematical concepts in the SDS YMI Tani Makmur District. This research method is class action research (PTK) with the aim of improving the understanding of mathematical concepts. The study was conducted in two cycles. In Cycle I, only 15 pupils understood the material, and the test results were 53.58%. For pupils who did not understand the material, there were 13 pupils with a percentage of 46.42%. In Cycle II, there were 26 pupils that did understand the materials, and the test results of the pupils were 92.85%, and for students who didn't understand the matter, there were 2 pupils and 7.1%. By using PhET, not only did it make the content of the fragment more interesting and real, but it also actively involved students in thinking creatively and producing learning conclusions on the fragmented material. The findings of this study suggest that the PhET medium can enhance the student's understanding of mathematical ideas by providing solutions to enhance understanding.
