Abstract

The primary issue encountered by the partner in this community service program is the lack digital learning media in mathematics instruction. At the junior high school level, particularly in Grade VII, students are undergoing a transition from concrete to abstract mathematical thinking, which necessitates the use of technology to help them visualize algebraic forms through graphs and various geometric representations of mathematical concepts. This community service program aims to enhance the quality of mathematics learning through the use of digital-based instructional media. The implementation consisted of several stages, namely school needs assessment, training on the use of digital applications, classroom mentoring by facilitators, and evaluation through questionnaires and interactive quizzes. The results of the program indicate that 161 students responded positively to digital-based mathematics learning. This is evidenced by the following findings: 93,16% of students reported enjoying the learning activities; 96,89% expressed interest in using GeoGebra, Desmos, and Symbolab; 93,16% stated that they understood how to use these applications; 83.85% agreed that the material presented was aligned with their learning needs at school; and 85,71% noted that the applications were easy to access. Thus, nearly all students experienced lessons that were engaging, enjoyable, and easy to understand. Keywords: digital learning, mathematics, Geogebra, Desmos, Symbolab

Abstract

This comparative study investigates the Technological Knowledge (TK) readiness of mathematics pre-service teachers in Indonesia and the Philippines. Using a structured online survey, data were collected from 136 participants in Indonesia and 93 in the Philippines. TK readiness was categorized into three levels: Ready, Moderately Ready, and Not Ready, with demographic factors such as age, sex, and school type examined as potential influences. The results indicate that Indonesian pre-service teachers demonstrate higher TK readiness compared to their Filipino counterparts. No statistically significant associations were found between TK readiness and demographic variables in either country. The findings suggest a need for targeted interventions in teacher education programs to enhance TK competencies and ensure effective technology integration in mathematics classrooms. Implications for curriculum design and future research are discussed.

Abstract

The rapid adoption of artificial intelligence (AI) in higher education has transformed students' learning practices, particularly in completing academic assignments and projects. However, the extent to which AI use influences academic performance remains inconclusive. This study investigated the effects of overall AI usage, the percentage of AI use in course projects, and mathematical disposition on undergraduate students' Grade Point Average (GPA). A quantitative correlational design was employed involving 39 undergraduate students. Data were collected using a validated AI usage questionnaire, a mathematical disposition questionnaire, self-reported percentage of AI use in course projects, and students' GPA. Multiple linear regression analysis was conducted after verifying the assumptions of normality, multicollinearity, and independence of residuals. The regression model was statistically significant (F = 6.247, p = .002) and explained 34.9% of the variance in GPA (R² = .349). Among the predictors, only the percentage of AI use in course projects significantly predicted GPA (β = −0.614, p < .001), whereas overall AI usage (p = .651) and mathematical disposition (p = .695) were not significant predictors. These findings indicate that AI use itself is not associated with lower academic performance. Instead, students' reliance on AI in completing course projects appears to be associated with GPA. Excessive dependence on AI-generated outputs without critical evaluation, revision, verification using credible academic sources, and integration of students' own reasoning may reduce the quality of academic work. Therefore, AI should be utilized as a learning assistant that supports critical thinking, creativity, and problem-solving rather than replacing students' independent intellectual engagement. The findings highlight the importance of promoting AI literacy and responsible AI use in higher education.

Abstract

When studying polyhedron, learning sources that are predominantly verbalistic can lead to difficulties in understanding the concept. Learners have diverse learning preferences for absorbing and processing information, known as learning styles. Therefore, learning media is required to accommodate features oriented towards the learning needs of the students encompass text, audio, video, animations, images, and augmented reality. This research aims to develop a valid and suitable e-module on polyhedron for maximizes students’ learning styles. This research is included in the limited research type that only focus-es on the development and validation stages without involving testing. The model supporting this level of this research is proposed by Richey and Klein, wherein the research phase is limited to evaluation. Throughout the research and development phases, the e-module is validated by content and media ex-perts. During the evaluation stage, every element produced in the e-module for flat-sided of three-dimensional shapes is found to be valid and highly suitable for accommodating students learning style. The result allows the identification of how each feature in the e-module supports visual, auditory, and kinesthetic learning styles.

Abstract

The program aimed to implement a learning aid that facilitates collaborative and enjoyable mathematics learning for seventh-grade students at State Junior High School 80 Jakarta. A total of 64 students participated in the program. This initiative was a collaborative effort between the Department of Mechanical Engineering and the Mathematics Education Program of Universitas Kristen Indonesia. The program consisted of three main stages: (1) a preliminary needs assessment through school observations and discussions with the principal and mathematics teachers, (2) the design and development of the Math Thinker instructional media and its accompanying learning module, and (3) the implementation of the instructional media in mathematics classroom activities. The implementation results overall mean score of 3,28 out of 4, indicated that students demonstrated positive responses toward the use of the Math Thinker instructional media. The learning activities successfully promoted collaborative group learning and created an engaging and enjoyable classroom environment. Furthermore, the instructional media optimized the mathematics learning process by encouraging active student participation and enhancing students' enjoyment of learning mathematics.
