Abstract

This research aims to: (1) To determine the validity of the STEM e-module based on Project Based Learning (PjBL) on chemical equilibrium material. (2) To determine students' responses to STEM e-modules based on PjBL on chemical equilibrium material. The research background highlights the challenges of 21st century learning where learning is carried out by utilizing technology and using an independent curriculum where the learning process is student-centered. So the STEM-PjBL e-module is an alternative that students can use in the learning process with flexibility. Science, Technology, Engineering, and Mathematics (STEM) is an alternative learning solution for the 21st century. The development model used is the ADDIE Model which consists of five stages including Analysis, Design, Development, Implementation and Evaluation. The e-module assessment instrument is a validation instrument from material and design experts as well as a student response questionnaire in the form of a Likert scale. The research results show that (1) the validation of the STEM e-module based on PjBL on chemical equilibrium material is "very valid" with an average percentage of 88.30%; (2) students' responses to the application of project-based learning-based STEM e-modules on chemical equilibrium material show that the e-modules developed are categorized as "very practical" with an average percentage of 90.51%.Keywords: E-Module, STEM, Project, Chemical EquilibriumDOI: 10.23960/jppk.v13i3.32219

Abstract

This study aims to determine the Effect of the Problem Based Learning (PBL) Learning Model Assisted by Canva Media on the Motivation and Learning Outcomes of Class X SMA Students on Atomic Structure Material. This research was conducted in the even semester of the 2024/2025 academic year at SMA Negeri 1 Percut Sei Tuan. The population in this study were all class X SMA students. The class sampling technique used in this study was purposive sampling of around 36 students who were relatively homogeneous in status. The research design used was a Pretest-posttest control group design. The instrument used was a multiple-choice test instrument related to atomic structure material. Hypothesis testing was carried out using a two-tailed t-test. The results obtained in this study indicate that there is an effect of the problem based learning model assisted by Canva media on student learning outcomes on atomic structure material. The average pretest score in the experimental class was 30.55 and the posttest in the experimental class was 84.86. This proves that there is an effect of the problem based learning model assisted by Canva media on student learning outcomes.
