Abstract

This research aims to determine the results of the validity and practicality of developing interactive e-modules assisted by Canva and Flip PDF Professional on Opportunity material for class X SMA. The type of research used is Research and Development (R&D) with the ADDIE development model which includes five stages: analysis, design, development, implementation, and evaluation. The research results show that the e-module product developed is included in the "very valid" and "very practical" categories. Validation was carried out by four validators, with percentage validity results: material expert (83%), lecturer media expert 1 (95%), lecturer media expert 2 (95%), and practitioner expert (90%), resulting in an average validity of 90 .75%. The implementation of a trial limited to 10 students showed a practicality level of 87.05%. Evaluation is carried out based on validator suggestions, resulting in improvements to media and material aspects. Thus, the interactive e-module developed is valid and practical for use in mathematics learning, facilitating students to learn independently and increasing active involvement in the learning process.

Abstract

This study aims to determine the effectiveness of using the GeoGebra application in enhancing the critical thinking skills of junior high school students on the topic of three-dimensional shapes. The background of this research is based on the importance of critical thinking in mathematics learning and the need for interactive and contextual learning media. The method used is a pre-experimental design with a One Group Pretest-Posttest model. This study involved a sample of 35 students from class VIII G at SMP Negeri 1 Gurah, Kediri Regency. The research instrument consisted of tests that measured indicators of critical thinking skills, administered before and after learning using the GeoGebra application. The data analysis results showed that most students experienced an improvement in their critical thinking abilities. The pretest score was 60.71, which increased to 81.88 in the posttest. Based on the N-Gain classification, 85.75% of students were in the medium to high category. This improvement indicates that GeoGebra is effective in supporting the mathematics learning process, particularly in assisting visual understanding of concepts and increasing student engagement. Therefore, the use of the GeoGebra application can be an alternative learning media to improve students’ critical thinking skills. The researcher extends sincere gratitude to all parties involved, especially to SMP Negeri 1 Gurah, Kediri Regency.
