Penerapan E-LKPD Interaktif Berbasis Problem Based Learning Berbantuan Liveworksheets untuk Meningkatkan Kemampuan Berpikir Kritis dan Hasil Belajar Fisika

The aim of this research is to determine the effectiveness of using Electronic Student Worksheets (E-LKS) assisted by liveworksheets based on the Problem Based Learning (PBL) model in improving critical thinking skills and learning outcomes. This research is Classroom Action Research with a One Groups Pretest-Posttest Design. The subjects of this research were all 36 students of class XI MIPA 1 SMA Negeri 1 Jember for the 2022/2023 academic year. Data collection for the critical thinking ability variable was obtained through a three-item essay test and for the learning outcome variable through a 15-item multiple choice test. The data obtained was analyzed using the N-Gain formula and the classical completeness formula. Based on the analysis, the N-Gain value for critical thinking skills was 0.531 (medium category) and learning outcomes increased with an N-Gain value of 0.26 (low category) in cycle I and 0.67 (medium category) in cycle II. Based on the results obtained, the use of multi-representation E-LKS assisted by live worksheets based on the PBL model has an effect on critical thinking skills and physics learning outcomes.
