IMPLEMENTASI BAHAN AJAR KIMIA DASAR BERBASIS STEM PROBLEM BASED LEARNING PADA MATERI SISTEM PERIODIK UNSUR UNTUK MAHASISWA PROGRAM STUDI PENDIDIKAN KIMIA
This study aimed to determine the effectiveness of implementing STEM-Problem Based Learning (STEM-PBL)-based Basic Chemistry teaching materials on the Periodic Table topic for students of the Chemistry Education Study Program. This study employed a QUAN-QUAL mixed methods approach with a pre-experimental One Group Pretest-Posttest Design. The subjects consisted of 61 students of the Chemistry Education Study Program at Sriwijaya University. Data were collected through learning outcome tests and observations of learning implementation. The data were analyzed using the N-Gain test and descriptive analysis. The results showed that the average pretest score was 55.25 and the average posttest score was 80.66, with an N-Gain score of 0.58 categorized as moderate. The implementation of STEM-PBL-based learning achieved a percentage of 83.5% in the very good category. Based on the findings, the implementation of STEM-PBL-based Basic Chemistry teaching materials was effective in improving students’ learning outcomes on the Periodic Table topic. Keywords: STEM-PBL, learning outcomes, Periodic Table, teaching materials.
