Abstract

The advancement of educational technology has driven the need for innovative learning media, particularly in abstract subjects such as mathematics, including statistics. However, teaching at SMP Negeri 1 Tilango is still predominantly lecture-based and relies on static media, which results in low student engagement and understanding. The purpose of this study is to develop interactive learning media based on Interacty for the statistics material taught to eighth-grade students. This study is a type of research and development (R&D) using the Plomp development model, which consists of five phases: initial investigation, design, realization/construction, test-evaluation-revision, and implementation. The subjects of this study were eighth-grade students at SMP Negeri 1 Tilango. Validation was conducted by media and content experts, resulting in feasibility percentages of 83.3% (highly feasible) and 80% (feasible), respectively. The limited product trial also showed very positive responses from both teachers (93.75%) and students (86.59%). These results indicate that the interactive learning media based on Interacty meets the criteria of practicality and feasibility in terms of both content and media. Therefore, the developed media is considered suitable for use in the mathematics learning process, particularly in statistics, as it can increase student engagement and help them understand concepts in a more enjoyable and interactive way.

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.

Abstract

Education today emphasizes the importance of numeracy literacy as part of the basic competencies in the Merdeka Curriculum. Numeracy literacy is an essential skill for students to understand and use mathematics in real-life contexts. This study aims to examine the influence of the Reading to Learn learning model on students' mathematical numeracy literacy skills in statistical material. This study uses a quantitative approach with a post-test-only control group design. Two eighth-grade classes at SMP Negeri 2 Suwawa were randomly selected as the sample. The experimental class was taught using the Reading to Learn model, while the control class received conventional instruction. The research instrument is an essay test that has been validated to measure mathematical numeracy literacy. Data analysis shows that the distribution is normal and the variance is homogeneous. The independent samples t-test revealed a significant difference between the post-test scores of the two groups, with the experimental class achieving a higher average. The effect size, calculated using Cohen's d, is 3.53, indicating a strong effect. These results indicate that the Reading to Learn model significantly improves students' mathematical numeracy literacy. This model helps students understand concepts contextually, think critically, and actively participate in learning.
