Abstract

The development of learning media enhances students' critical thinking skills, especially in elementary mathematics. This research produced an interactive E-Comic focusing on addition material for fourth-grade students, following the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Validation by media experts, material experts, language experts, and education practitioners showed high feasibility with an average score of 92%. Small group trials with 6 students yielded 92%, while larger group testing with 32 students achieved 97%. Pre-test and post-test results demonstrated significant improvement, increasing from 44.06% to 83.98%. These findings prove the E-Comic's effectiveness in improving learning outcomes and fostering critical thinking skills. The engaging visuals and interactive presentation motivate students, making mathematics learning more enjoyable and meaningful. Therefore, the E-Comic proves to be an effective learning medium for enhancing both students' critical thinking abilities and achievement in addition material. The ADDIE model ensured systematic development and proper validation standards were maintained throughout the research process, resulting in a highly effective educational tool.

Abstract

This research was motivated by students’ difficulties in describing and visualizing mathematical concepts, particularly in plane figure material. Students also struggled to relate these concepts to real-life situations, limiting their ability to apply mathematics in everyday contexts. The research aimed to examine whether the use of the Qreatif Application Media could enhance students’ mathematical representation abilities. A quantitative approach was used with a quasi-experimental design, specifically a nonequivalent group posttest-only control design. Data were collected through tests administered to both the experimental and control classes. Data analysis involved an independent sample t-test and an effect size test. The results showed that the experimental class achieved an average score of 89.61 in mathematical representation ability, while the control class averaged 77.19. The t-test yielded a significance value of 0.000 < 0.05, indicating a significant difference between the two groups. Therefore, it can be concluded that the use of the Qreatif Application Media had a positive impact on students’ mathematical representation abilities in plane figure material compared to conventional teaching methods.
