The Effectiveness of Online Learning Assisted by Google Classroom on Students' Learning Outcomes about Energy

Abstract The study aims to determine the effectiveness of google classroom in online learning towards students’ learning outcomes on Energy topic at SMAN 1 Nanga Mahap. The design of this study was pre-experimental with one group pre-test post-test design. The data collection technique used was asessment, which were carried out by collecting test results before and after treatment. Data analysis was carried out using the g factor formula (N-gain), recapitulation percentage, and effect size. The results showed that: (1) Students' learning outcomes were in the medium category, showed by the N-gain value obtained 0.40142. Learning outcomes increased by 8,625, from 71,625 (pre-test) to 80.25 (post-test). (2) The percentage of students’ learning outcomes increased by 8% from 72% (high category) to 80% (high category) after treatment. (3) The use of google classroom in online learning effectively improves students’ learning outcomes at SMAN 1 Nanga Mahap. The standard deviation was 18.31, and the effect size (ES) value was 0.470 in the medium category. Based on the results, it is hoped that schools and teachers can consider it in choosing effective online learning media to improve students’ learning outcomes. Keywords: Energy, Google Classroom, Learning Outcomes, Online Learning, Pre-Experimental
