Abstract

This study aims to enhance students' mathematical problem-solving skills through the implementation of the Problem-Based Learning (PBL) model in the topic of quadratic equations. The research was conducted using the Classroom Action Research (CAR) method based on the Kemmis and McTaggart spiral model, consisting of two cycles with the stages of planning, action, observation, and reflection. The participants were 18 eleventh-grade students from a vocational high school (SMK) in Sleman. The findings revealed a significant improvement in students' mathematical problem-solving abilities, with the average score increasing from 75 in Cycle I to 84.72 in Cycle II. The PBL model proved effective in enhancing problem-solving skills. Challenges encountered during Cycle I, such as students' difficulties in understanding problems and lack of participation in group activities, were successfully addressed in Cycle II through improvements, including clearer visualizations in the Student Worksheets and more heterogeneous group arrangements. This study concludes that PBL is an effective teaching model for fostering meaningful learning and improving students' learning outcomes in the topic of quadratic equations.

Abstract

Ethnomathematics represents a paradigm within mathematics education that centers on integrating and applying mathematical principles, concepts, and methodologies embedded within the cultural fabric of specific communities. Within the Indonesian cultural milieu, traditional games constitute a significant aspect. Hence, this study investigates the traditional game of Congklak, aiming to explicate its underlying modulo concept. Employing a qualitative research design grounded in ethnographic methodology, the investigation draws upon a multifaceted approach, including a literature review, documentation analysis, participant observation, and interviews with custodians of the Congklak tradition. Data validation is achieved through triangulation of sources and methods. Data analysis involves iterative data reduction, presentation, and inference drawing processes. Findings reveal the presence of a modulo concept within the traditional Congklak game, which governs the determination of the final seed distribution position. Furthermore, additional mathematical elements, notably addition operations, are identified. The identified modulo concept offers a compelling avenue for enriching mathematical pedagogy, particularly in the realm of modulo arithmetic operations, by providing an alternative cultural context for learning.
