Abstract

This research aims to determine the perceptions of 2024 geography education students regarding the use of virtual rock microscope learning media in the general geology course based on 6 indicators of student perceptions towards the use of virtual rock microscope. This research is a descriptive quantitative study conducted in the city of Padang with a research sample consisting of 2 classes from the 2024 batch of the Geography Education Study Program, totaling 41 students. The sampling technique in this study used the purposive sampling method. The research results show that 1) the use of a virtual rock microscope in general geology learning meets the good criteria at 86%, 2) the media used clarifies students' understanding of the material presented at 84% good criteria, 3) it provides feedback that is meaningful for students and lecturers during the learning process through the virtual rock microscope at 85% good criteria, 4) it identifies the effectiveness of access and the use of features available in the virtual rock microscope at 85% good criteria, 5) difficulties when using the virtual rock microscope meet the good/no difficulty criteria at 81%, 6) obstacles when using the virtual rock microscope meet the good/no obstacles criteria at 81%. The conclusion of students' perceptions regarding the use of virtual rock microscopes as a learning medium for rock material in the general geology course overall falls into the good or positive category.

Abstract

Critical thinking skills are essential in Geography learning, requiring analysis of spatial and regional phenomena. However, many students find it difficult to develop these skills due to teaching methods that do not actively engage them. This study aims to analyze the effect of the Discovery Learning model based on Liveworksheets on the critical thinking skills of 10th-grade students in Phase E at SMA Negeri 7 Padang. The method used is quantitative with a quasi-experimental design and a sampling technique of purposive sampling, involving 72 students divided into experimental and control groups. The instrument used consists of 10 essay questions based on Ennis' indicators. The pretest results showed low initial abilities in both classes. The average pretest score for the experimental class was 20.86, and for the control class, it was 19.08. After the treatment, the average posttest score for the experimental class increased to 24.67, while for the control class, it was 19.42. The t-test showed a significance value of 0.000 (< 0.05), indicating a significant difference between the two groups. The N-Gain value for the experimental class was 0.1305 and for the control class was 0.0865, both of which fall into the low category. Nevertheless, the Liveworksheets-based Discovery Learning model proved more effective in improving students' critical thinking skills compared to conventional learning.
