Abstract

The Education plays a crucial role in developing cognitive skills, including critical thinking and problem-solving, which are essential for student learning and future competitiveness. However, many students in Indonesia face difficulties in understanding mathematics, particularly on topics such as ratios, due to the limited use of interactive learning media. This study aims to develop an interactive learning media using Visual Basic Application (VBA) for PowerPoint and to evaluate its validity and practicality. The development followed the ADDIE model, which includes five stages: analysis, design, development, implementation, and evaluation. Validation was conducted to assess both media and content quality, while practicality was measured through responses from students and teachers. Data were collected using validation sheets, questionnaires, and scoring rubrics, and analyzed quantitatively to determine validity and practicality categories. The results showed that the learning media obtained an average score of 3.09 for media validity and 3.47 for content validity, both categorized as “very valid.” Student responses reached a score of 740 out of 800, while teacher responses achieved a perfect score of 40 out of 40, indicating that the media is highly practical. Based on these findings, it can be concluded that VBA-based PowerPoint learning media is valid, practical, and effective in enhancing cognitive engagement and supporting mathematics learning, particularly on the topic of ratios.

Abstract

Education plays an important role in developing students’ potential, especially critical and creative thinking. Mathematics, as a core subject, supports students’ problem-solving ability, which involves understanding, procedure selection, and application in new contexts. One factor that may influence this ability is self-confidence, as confident students are more persistent and independent in solving problems. This study aimed to examine the effect of self-confidence on students’ mathematical problem-solving ability. The research employed a quantitative correlational design with a purposive sample of 60 seventh-grade students at SMP Negeri 8 Kota Gorontalo. Instruments consisted of a mathematical problem-solving test and a self-confidence questionnaire. Data were collected through tests and questionnaires, then analyzed using simple linear regression and correlation coefficient tests. The findings revealed that self-confidence significantly affects students’ mathematical problem-solving ability. Students with higher self-confidence tended to achieve better outcomes. The correlation coefficient was 0.6923 (strong positive), with a coefficient of determination (R²) of 47.22%, indicating that self-confidence contributed nearly half of the variation in problem-solving ability. The remaining 52.78% was influenced by other factors not examined in this study, such as math anxiety, learning habits, and environmental support. In conclusion, self-confidence has a positive and significant effect on mathematical problem-solving ability, suggesting the importance of fostering students’ confidence alongside academic skills.
