Implementation of PBL-Based E-Worksheets to Enhance Students’ Mathematical Representation

Abstract

This study aims to improve students' mathematical representation skills in work and energy by applying PBL-based E-LKPD. This study used a one group pretest posttest design involving 32 students of class XI-D SMAN 1 Nglames. The research instruments included a student response questionnaire and a pretest-posttest sheet. The results of this study indicate that students responded positively to the application of PBL-based E-LKPD with a percentage of 84.84% in the excellent category. The average pretest and posttest scores for mathematical representation were 40.31% and 76.25%, with an N-Gain percentage for mathematical representation skills in the moderate category of 0.575. The results of this study indicate that the application of PBL-based E-LKPD can improve students' mathematical representation skills in the subject of work and energy.
