Abstract

The study aims to improve student learning about flat triangle through the student team achievement division learning model. The application of STAD, the researcher used an experimental quantitative research with a quasi experimental design. Research sample is VII5 class (using STAD) dan VII6 class (using discovery learning) at SMP Negeri 15 Ambon, Baguala Distric, Ambon City. The instrument using it essay test dan the result is analizeby descriptive statistic and inferential statistic the resultof analize show that the average student learning from VII5 class is 68,67 and average student from VII6 class is 61,39 this means that student learning using STAD model have greatly improve when compared with student learning with discovey learning model

Abstract

STEM education (Science, Technology, Engineering, and Mathematics) in Indonesia, particularly in Maluku, faces the challenge of a skills gap that impacts economic growth. The goal of this training is to enhance teachers' competencies in integrating STEM and Deep Learning into the learning process. The training program is carried out by the Community Service Team from the Faculty of Teacher Training and Education at Pattimura University to improve teachers' understanding and ability to implement deep learning (DL) in STEM education. The results of the pre- and post-tests showed a significant increase in teachers' understanding and ability to adopt innovative educational approaches. The integration of STEM and DL has great potential to improve the quality of education. Teacher training and collaboration between educational institutions and the community are very important in enhancing the quality of education. Recommendations: (1) continuously improve teacher training, (2) develop curricula that support the integration of STEM and DL, and (3) enhance collaboration between universities and local schools to improve the quality of education and prepare students to face 21st-century challenges. Thus, it is expected to improve the quality of education and enhance students' ability to think critically and solve problems in the technological era.

Abstract

This study investigates students' mathematical problem-solving ability through Coastal Culture–Based Realistic Mathematics Education (RME). Problem-solving is a critical 21st-century competency and a central goal of mathematics education; however, conventional instruction often fails to connect mathematical concepts with students' real-life contexts. The objective of this study is to analyze the effect of RME on students' mathematical problem-solving abilities after they receive realistic learning based on coastal potential. A quasi-experimental design with a pretest–posttest control group was employed, involving 120 eighth-grade students from three junior high schools in West Seram Regency. The experimental group received coastal potential–based RME instruction, while the control group experienced conventional learning. Data were analyzed using descriptive statistics, normality and homogeneity tests, independent t-tests, and ANOVA. The results revealed a significant difference in improvement between the experimental and control groups (p 0.05), with the experimental group achieving a moderate and effective N-gain (67.8%), compared to the ineffective gain in the control group (20.8%). The findings conclude that coastal culture–based RME is more effective in enhancing students' problem-solving abilities than conventional methods. This study contributes to mathematics education by integrating local cultural context into RME, providing an innovative framework for contextualized learning in secondary education.

Abstract

This community service activity aims to improve the numeracy skills of teachers in South Buru Regency through Community-Based Research (CBR) training. This approach places teachers as partners who are actively involved in the entire activity process, from the planning stage, implementation, to program evaluation. The activity was attended by 80 teachers from elementary and junior high school levels. The training materials include understanding basic numeracy concepts, the difference between numeracy and calculation skills, strategies for integrating numeracy into learning, as well as the application of numeracy in various everyday life situations. The effectiveness of the activities was measured using pre-test and post-test instruments that covered six aspects of teachers' numeracy skills assessment. The training results showed a significant improvement in all measured aspects. The average pre-test scores ranged from 50–58, while the post-test results increased to 78–85. In addition to the improvement in evaluation results, observation results also showed an increase in participation, enthusiasm, confidence, and teachers' ability to discuss and simulate numeracy learning. Thus, this activity is effective in enhancing teachers' conceptual understanding and strengthening their ability to apply numeracy learning that is more contextual, innovative, and in accordance with the needs of students in the school environment.
