Effectivity of Guided Discovery Learning Supported with Elemental Chemistry E-Module on Students Learning Outcomes

This study aims to analyze the effectiveness of the elemental chemistry e-module based on guided discovery learning in improving student learning outcomes. The research was conducted in class XII at SMAN 13 Padang with 36 students. The type of research used is quasi-experimental with a one-group pretest-posttest design. Data analysis used a t-test. Sampling was done using simple random sampling. The obtained n-gain value was 0.49 (medium category). In conclusion, the guided discovery learning-based e-chemistry module effectively improves student learning outcomes with high criteria.
