B-Geo Module is a module that has been developed using the brain-based teaching approach (BBTA) integrated with GeoGebra Software (B-Geo Module) is expected to help students’ problem-solving abilities of the topic of Differentiation. The BBTA is a strategy that uses brain-based learning techniques. It was created to be consistent with the individual brain's tendencies and ideal functions in order to ensure that pupils can learn efficiently. Therefore, the proposed of this study is to explore the possible effects of the B-Geo Module on problem-solving abilities for the Topic of Differentiation. A quasi-design of pre-test and post-test experiments was utilized in this study, which included 118 form 4 pupils from rural secondary schools. For school selection, the researchers employed cluster sampling approaches, and for sample selection, they used an intact group. The schools were separated into two groups: experimental and control. The experimental group used the B-Geo Module, while the control group used traditional ICT modules. The instrument used was the Problem-Solving Test of Differentiation. The results of the data analysis showed the effectiveness of the B-Geo Module in the problem-solving abilities in the topic of Differentiation among rural secondary school pupils. The multimedia such as GeoGebra can be the tools for BBTA to facilitate Additional Mathematics teachers in secondary schools to help students solve problem and improved their learning in the topic of Differentiation.

This study aims to explore the hidden mathematical concepts behind the rice farming activities of Pandanwangi Cianjur. The research method is qualitative research with an ethnographic approach. The research location is in Pandanwangi Cultural Village, Bunikasih Village, Warungkondang District, Cianjur Regency, West Java. Pandanwangi Cultural Village was deliberately built by the Cianjur Regency Government to further introduce pandanwangi rice, which is the superior local variety of Cianjur Regency. Pandawangi rice farmers' cultural activities contain mathematical concepts that arise when determining seed class, number of seeds, nursery preparation, final seed selection with salt solution, seeding in nurseries, nursery maintenance, preparation of planting land, planting, fertilization in planting areas, planting maintenance, harvest, and post-harvest. The findings of this study show that there are mathematical concepts in agricultural activities on geometric content, including determining points, lines, angles, the area of flat shapes, the similarity of flat shapes, and algebra, including comparisons, percentages, and social arithmetic. The results of the research can be used as a teaching module to facilitate learning for students in the school curriculum.

Understanding school stress is essential, given the significant time students spend in school and its impact on well-being. Acknowledging its importance, this study aimed to assess the level of school stress among Malaysian secondary school students. The respondents in this study consisted of 485 Malaysian secondary school students, selected through multistage sampling techniques to ensure national representativeness. Data were collected using a school-related stress questionnaire adapted from the shortened version of the adolescent stress questionnaire (ASQ-S). Data were analyzed using descriptive statistics, Rasch Wright mapping, independent samples t-tests for gender differences, and one-way ANOVA for grade and regional comparisons. The results indicated that, overall, Malaysian secondary school students experience low levels of school stress. Descriptively, female students reported higher levels of school stress than their male counterparts. Among different forms, Form 4 students reported the highest level of school stress, followed by Form 1 students. Regionally, students from the central and southern zones exhibited the highest levels of school stress. This study contributes to a better understanding of school stress among Malaysian secondary school students, providing insights for developing strategies to reduce stress in schools.

Background: Coaches’ transformational leadership plays an important role in shaping a positive psychological environment and enhancing athletes’ motivation in team sports. However, empirical studies examining this relationship among university team sport athletes remain limited, particularly in non-professional sports settings. Objectives: This study aimed to examine the influence of coaches’ transformational leadership on the motivation of university team sport athletes. Method: This study employed a quantitative correlational design with an ex post facto approach. The participants comprised 32 student-athletes from the Universitas Pendidikan Indonesia Hockey Club, selected through purposive sampling. Data were collected using the Differentiated Transformational Leadership Inventory (DTLI) and the Sport Motivation Scale II (SMS-II). Result: The findings revealed that coaches’ transformational leadership significantly influenced athletes' motivation (p < 0.05). The coefficient of determination (R²=0.488) indicated that transformational leadership explained 48.8% of the variance in athlete motivation. Conclusion: The study demonstrates that transformational leadership positively influences the motivation of university team-sport athletes. Coaches who provide inspiration, individualized support, and a clear vision may help strengthen athletes’ motivation and commitment within the team environment. These findings highlight the importance of applying transformational leadership approaches in university sports programs to support athlete development and performance.
