Abstract

This community service program was implemented to address the challenges faced by mathematics teachers in applying differentiated instruction. The program aimed to enhance teachers' competencies in implementing differentiated learning and integrating technology as a teaching aid in mathematics. The training focused on improving teachers' understanding of differentiated instruction, particularly in mathematics education, and equipping them with the skills to utilize technology in the classroom. The methods used included socialization, training, technology implementation, mentoring, and program sustainability. Results showed that 88.2 percent of teachers required technology training, and 80.64 percent expressed interest in participating. Training evaluations revealed an improvement in teachers’ ability to identify students' learning styles and develop technology-based learning media. Teachers reported that Kodular facilitated the creation of interactive and student-centered learning tools. The program successfully enhanced teaching effectiveness, student engagement, and teacher creativity, despite technical challenges such as internet connectivity issues. The TeknoMatika Training has the potential to serve as a model for teacher competency development in other regions, contributing significantly to technology-based educational innovation.

Abstract

The mathematics learning process in schools often faces challenges such as low student engagement, limited conceptual understanding, and the dominance of less interactive teaching approaches. These conditions hinder the development of higher-order thinking skills, particularly students’ mathematical reasoning ability. Therefore, innovative and technology-assisted learning models are required to improve the effectiveness of mathematics instruction. This study aims to examine the improvement of students’ mathematical reasoning ability through the implementation of the Joyful Learning model assisted by GeoGebra. The research employed an experimental method using a One Group Pretest–Posttest Design. The population consisted of all seventh-grade students of SMP 3 Al-Muhajirin, while the sample comprised 29 students from Class VII E selected using a simple random sampling technique. Data were collected using an essay-based test designed to measure mathematical reasoning ability and administered before and after the learning intervention. Statistical analysis was conducted using normality testing and the Wilcoxon signed-rank test with the support of IBM SPSS Statistics 24. The results indicate a statistically significant difference between pretest and posttest scores, showing an improvement in students’ mathematical reasoning ability after the implementation of the Joyful Learning model assisted by GeoGebra. This improvement reflects students’ enhanced ability to propose conjectures, identify patterns, apply mathematical manipulation, and draw logical conclusions. These findings suggest that the integration of the Joyful Learning model and GeoGebra is an effective instructional approach for fostering mathematical reasoning ability and creating a more engaging mathematics learning environment.
