Abstract

This study aims to develop an android-based learning class XI mathematics learning media to support the mathematics learning process both online and face-to-face. This research type was Research and Development (R&D). The steps of the development procedure including: the design stage, the production stage, and the evaluation stage. The subjects in this study were validated in the early stages by experts (design experts, media experts, and subject matter expert). Then proceed with individual-scale product trials, small group-scale trials and field trials. Data collection techniques in this study used a questionnaire. Questionnaires are used to obtain information and data to measure the feasibility of the resulting product. Based on the assessments made by experts, the average percentages were: design experts (79.17), media experts (80.09), subject matter experts (82.09). So, from the overall average value, it can be concluded that on the validation the experts get the eligibility criteria ”Good”. Based on the results of field trials, the percentages obtained are: individual scale (82.33) small scale (82.44), large scale (82.91). So, it can be concluded that the overall average value of the percentage of field trials on the respondents obtained the eligibility criteria of ”Very Good”. In other words, the media developed in this study was considered feasible and very good for use in learning mathematics.

Abstract

Twenty-first-century education emphasizes the importance of critical thinking skills, yet the utilization of teaching aids in elementary science education remains suboptimal. This study examined the effect of solar system teaching aids on sixth-grade students' critical thinking skills at SD Negeri 01 Tekorejo. A quasi-experimental one-group pretest-posttest design was employed with 30 students selected through total sampling. The instrument consisted of a five-item essay test developed based on critical thinking indicators: identifying problems, providing arguments, evaluating arguments, drawing conclusions, and formulating solutions. Data were analyzed using descriptive statistics and the Wilcoxon Signed-Rank Test due to non-normal data distribution. Results showed a significant increase in mean scores from 11.60 (pretest) to 16.00 (posttest), with a significance value of 0.013 (p < 0.05), indicating that teaching aids significantly enhanced students' critical thinking skills. The three-dimensional solar system models facilitated transformation of abstract astronomical concepts into concrete representations, enabling students to engage in hands-on exploration, collaborative discussion, and analytical reflection. These findings align with Piaget's cognitive development theory, demonstrating that concrete manipulatives effectively support elementary students at the concrete operational stage. This study contributes empirical evidence for the efficacy of physical teaching aids in developing higher-order thinking skills and recommends systematic integration of concrete instructional media to strengthen conceptual understanding and support twenty-first-century competencies in elementary science education.
