Abstract

Problem solving skills is one of the most important skills students should achieve in mathematics. However, students' mathematical problem-solving skills still low. This research offers classpoint mathematics gamification in digital mathematics module based on problem-based learning. Thus, this research was conducted to develop a valid, practice, and effective mathematics digital module based on problem-based learning model with classpoint mathematics gamification (ChePomathGo) in improving students’ problem solving skills. This study used the Plomp development model, including the preliminary research, prototyping, and assessment phases. Preliminary research involving 32 students and 1 teacher and prototyping and assessment phase involving 9 students in seventh grade junior high school. Data analysis used are descriptive analysis. The result shows that the mathematics digital module based on problem-based learning model with ChePomathGo is valid with an average score of 3.67 (very valid category), practice based on students’ and teachers’ positive responses, and effective to improve students’ problem solving skills based on the results of the students' mathematical problem-solving skills test in small group evaluations with an average score of 75% (effective category). The implications of this research is the digital mathematical module developed can be a guidelines for researchers and teachers to improve students’ mathematical problem-solving skills.

Abstract

A tree graph is a connected graph and has no circuits. Tree graphs used in this study include: broom graph, centipede graph, and Banana Tree graph. Graph coloring is the process of giving color to graph elements with the rule that neighboring elements must not have the same color, and the number of colors used must be as minimal as possible. b-coloring of a graph G is a coloring of the vertices of G such that each color class has at least one vertex adjacent to all other color classes. The b-chromatic number of a graph G is denoted by φ(G), is the largest integer k such that G has a b-coloring with k colors. The limit of b-coloring of graph G with maximum degree ∆(G) is as follows, χ(G) ≤ φ(G) ≤ ∆(G) + 1.χ(G) is the chromatic number of a graph G where χ(G) is the minimum value of the color required for proper coloring of graph G. While ∆(G) is the maximum degree of the vertices in graph G. This study uses an exploratory research type with an axiomatic deductive method and a pattern detection method. Based on this study, the results of the b-coloring analysis on the tree graph family are known. The results of this study are expected to be used as study material and the development of scientific knowledge related to b-coloring analysis on other graphs.

Abstract

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.

Abstract

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.

Abstract

The growing availability of technology offers opportunities to enhance mathematics teaching and learning. For mathematics educators, technology can serve as a form of instructional innovation alongside other indicators of innovative practice, such as student-centered learning, the use of real-world contexts, active concept construction, problem-solving, interaction, and the promotion of students’ motivation and attitudes. This study aims to describe mathematics teachers’ skills in designing innovative technology-based mathematics learning. A descriptive–exploratory mixed-methods approach was employed involving 20 mathematics teachers enrolled in a Mathematics Education graduate program. Quantitative data were collected through questionnaires examining perceptions of the importance and use of technology in mathematics learning. Qualitative data were obtained from lesson plan design tasks and semi-structured interviews and analyzed using indicators of innovative mathematics learning. The results show that 93.8% of participants perceived technology as necessary in mathematics learning; however, 68.8% primarily used it to verify solutions after manual completion, and 25% believed that direct technology use might hinder conceptual understanding. Analysis of lesson plans revealed the use of GeoGebra, Scratch, YouTube, and online applications. Overall, participants demonstrated varying levels of skill, with strengths in basic technology use and student-centered approaches but limited evidence of transformative pedagogical integration.

Abstract

This community service program aimed to strengthen elementary school teachers’ capacity to integrate ICT-based deep learning pedagogy in improving students’ numeracy and computational thinking (CT) literacy. The program involved 30 teachers within a local Teacher Learning Community and was implemented through participatory workshops and structured mentoring using a one-group pre-test–post-test design to examine program impact. The intervention focused on enhancing teachers’ competence in designing ICT-integrated lesson plans, learning activities, and assessments aligned with numeracy and CT indicators. Data were collected through teacher self-assessment, classroom observation, and students’ pre- and post-tests and analyzed descriptively to determine mean improvement and percentage gain. The results demonstrated a 24% increase in teachers’ ICT pedagogical competence, indicating strengthened instructional capacity. As a follow-up impact of improved teaching practice, students’ numeracy achievement increased by 24%, and computational thinking performance improved by 20%. These findings confirm that empowering teachers through ICT-integrated deep learning contributes to measurable improvements in instructional quality and supports the development of higher-order literacy skills. Overall, the program achieved its objective by reinforcing teacher capacity as the primary outcome, with positive learning gains emerging as a direct pedagogical impact within elementary classrooms.
