Abstract

This research aims to assess the validity and effectiveness of an e-module based on Phenomenon-Based Learning (PBL) for teaching acid-base solutions, developed using the ADDIE model, which includes five stages: Analysis, Design, Development, Implementation, and Evaluation. The development method is well-suited for creating educational materials. In this study, the e-module was validated by experts in chemistry content and media design. The validation results indicated that the e-module was highly valid across various aspects, including content, presentation, language, graphics, PBL characteristics, appearance, and software utilization, with validity percentages of 96.00%, 96.66%, 100.00%, 92.00%, 96.36%, and 96.66%, respectively. Additionally, an e-module trial was conducted with feedback from two chemistry teachers and 20 students. The responses were overwhelmingly positive, with effectiveness ratings of 96.66% and 98.76%. Based on these findings, it can be concluded that the e-module developed with the Articulate Storyline application for acid-base solution materials is both valid and effective for use in the learning process.

Abstract

This study aims to identify the profile of students' misconceptions on chemical equilibrium and to determine the sources of these misconceptions. This study used a descriptive method with quantitative and qualitative approaches and was conducted at SMA Negeri 7 Pekanbaru. The research subjects involved 187 11th-grade students who had studied chemical equilibrium. Data collection was conducted using a five-level diagnostic test instrument consisting of 15 questions and structured interviews. The results showed that the average percentage of students experiencing misconceptions was relatively low, at 20.93%. Analysis of the sources of misconceptions showed that the main cause of misconceptions came from students' personal thoughts, with a percentage of 24.15%. Other contributing sources included friends (20.66%), teachers (18.78%), the internet (18.35%), and books (18.06%). These findings indicate that students' misconceptions are more influenced by independent constructions of understanding that do not align with scientific concepts than other external factors.
