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

Conventional learning methods tend to be monotonous, often making junior high school students less interested and difficult to understand the material, especially in statistics. Therefore, it is necessary to develop more interactive and interesting teaching materials to increase students' interest in learning and understanding. This research aims to develop of statistics e-modul valid and practical teaching using the flipbook on junior high school. This study is classified as Research & Development using Thiagarajan's 4D model. The 4D stages of Thiagarajan include Define, Design, Develop, and Disseminate. The data collected using the instruments employed in this study include a validation questionnaire consisting of subject matter experts and media experts, a readability test questionnaire, and student response questionnaires, as well as teacher response questionnaires used to measure the practicality of the developed e-module. The results of the the development of e-modul using the flipbook application falls under the criteria of validity and practicality. The level of validity can be seen from the validity scores of 74% for content validation and 78% for media validation, which fall within the valid category, as well as practicality scores were obtained from the student response questionnaire with a score of 85% and the teacher response questionnaire with a score of 98%. It can be concluded that the development of e-modules using the flipbook application for statistics material for eighth grade, as produced by this research, is valid and practical, and therefore considered suitable for use in learning.

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.
