Development of Chemistry Electronic Student Worksheets Problem Based Learning Model to Improve Student’s Learning Outcome in Grade X Senior High School on Stoichiometry Topic

Abstract

This study aims to improve student learning outcomes of class X high school after using the Chemistry electronic student worksheets Problem Based Learning Model's which was developed with website. This is a research and development that uses the ADDIE Model. The data analysis technique used is quantitative and qualitative descriptive. Analysis stage obtained students need interactive teaching materials. In design, electronic student worksheets was designed using web. In development, product was validated by material and media experts. The result showed that product was feasible to be used in chemistry learning. In implementation, students used product in Stoichiometry topic. In evaluation, students had post-test. With One Sample T-Test was obtained learning outcomes of students were higher than the minimum completeness criteria where the sig. 0.000 < 0.05 and tcount > ttable (10.289 > 1.690). it can be concluded that the use of electronic student worksheets problem based learning model can improve student learning outcomes on Stoichiometry topic.
