Abstract

This research sought to explore how the Project-Based Learning (PjBL) model affects the learning interest and self-efficacy of eleventh-grade students in Senior High School. Employing a quantitative quasi-experimental design, the study utilized a sample of eleventh-grade students selected through simple random sampling. Data were gathered using questionnaires and observational methods and analyzed using a multivariate analysis of variance (MANOVA) test. The results underscored the notable influence of the PjBL model in enhancing learning interest and self-efficacy. The PjBL approach positively affected these variables in the experimental group of 28 students. The robustness of these results was confirmed by Pillai's Trace, Wilks' Lambda, Hotelling's Trace, and Roy's Largest Root tests, each demonstrating F-values with a significance level of 0.000, well below the threshold of 0.05. Moreover, the Coefficient of determination (R²) revealed that the PjBL model accounted for 73.5% of the variance in learning interest and 90.2% in self-efficacy, with the remaining variance being attributable to other factors not addressed in this study.

Abstract

Background: HTML5 Package media, equipped with features and displays, provides a clearer visual display in learning geometry compared to traditional lecture-based teaching. This approach facilitates students in observing and understanding geometry concepts, positively impacting their self-efficacy.Aim: The study aims to assess the impact of HTML5 packages on students' understanding of geometry concepts and their self-efficacy.Method: The research, a quasi-experimental study, used simple random sampling to select 63 students. Data were collected through tests and questionnaires, and the analysis was conducted using MANOVA.Result: The findings reveal a significant effect of the HTML5 Package on both concept understanding and self-efficacy. The experimental group scored higher than the conventional group, with significant values in Pilae Trace, Wilk Lambda, Hotelling Trace, and Roy's Largest Root analyses.Conclusion: The HTML5 Package media effectively enhances the understanding of geometry concepts and self-efficacy among students. While the effect size is modest, it is notably better than conventional learning methods. The study suggests broader application and research involving more students and diverse mathematical topics could yield more influential results.

Abstract

Background: Elementary school students in Aceh Tamiang often struggle with problem-solving which negatively impacts their confidence. To address this issue, a new teaching approach called PBL-Reathnomath was developed, combining problem-based learning with real-world math examples and cultural references.Aim: This study aimed to determine the effectiveness of the PBL-Reathnomath model at improving students' problem-solving skills and self-efficacy.Method: A study was conducted involving randomly selecting participants and dividing them into two groups. One group learned using the new PBL-Reathnomath model while the other group learned using traditional methods. Data were collected through tests and surveys and the results were analyzed using statistical methods.Results: The findings showed that the PBL-Reathnomath model significantly improved both the problem-solving abilities and self-efficacy of the students. The group that used this new model performed better on average than the group that used traditional methods. Further analysis confirmed that the PBL-Reathnomath model simultaneously affected problem-solving and self-efficacy, explaining a substantial portion of the variation in these outcomes.Conclusion: While the effect size was smaller compared to conventional learning, the study concluded that PBL-Reathnomath is a valuable and specialized approach for improving problem-solving skills and boosting self-confidence among elementary school students.
