Abstract

Mathematics learning, particularly at the junior secondary level, is often perceived as abstract and difficult, which can reduce students’ motivation and engagement. One instructional strategy that has the potential to address this issue is the use of YouTube-based instructional video media. This study aims to describe teachers’ and students’ interpretations of the use of video media in mathematics learning at SMP Negeri Satap 1 Bajawa, as well as to identify the challenges encountered during its implementation. The study employed a qualitative descriptive approach. Data were collected through classroom observations, interviews with mathematics teachers and students, and documentation of learning activities. The data were analyzed using an interactive model consisting of data reduction, data display, and conclusion drawing. The findings indicate that the use of YouTube-based video media positively influences the learning process by increasing students’ motivation, focus, and conceptual understanding of mathematical material. Students perceived video-based learning as more interesting and enjoyable compared to conventional instruction, and they appreciated the ability to replay learning content independently. Teachers reported that video media supported clearer explanations of abstract concepts and improved student engagement. However, several challenges were identified, including limited availability of supporting facilities and the pace of explanations in some videos, which were considered too fast for certain students. Overall, the study concludes that YouTube-based instructional video media have strong potential to support more meaningful and contextual mathematics learning, particularly in schools with limited resources, provided that the content and implementation are adapted to students’ learning needs..

Abstract

Purpose: This study aims to analyze the instructional needs and perceived usefulness of ethnomathematics-based learning modules in senior high school mathematics. The focus is placed on curriculum alignment, integration of local cultural contexts, and the potential of these modules to support contextual and meaningful learning experiences for both teachers and students. Method: A descriptive mixed-methods design was employed, combining quantitative and qualitative approaches. The participants consisted of four mathematics teachers and twenty students drawn from four senior high schools in the Golewa region. Data were collected using closed-ended questionnaires based on a four point Likert scale to capture perceptions related to instructional needs, relevance, and usefulness of ethnomathematics based modules. To enrich and validate the quantitative data, semi-structured interviews were conducted with selected participants. Quantitative data were analyzed using percentage-based Likert index calculations, while qualitative data were analyzed descriptively to support interpretation of the findings. Findings: The results indicate that the availability of ethnomathematics-based teaching modules in senior high school mathematics remains limited. From the teachers’ perspective, the average needs score reached 85.5%, highlighting strong demands for contextual learning resources aligned with the curriculum and local culture. From the students’ perspective, the perceived usefulness score averaged 82%, indicating positive responses toward increased engagement, improved conceptual understanding, and stronger connections between mathematics and everyday life. Significance: The findings demonstrate that ethnomathematics-based learning modules represent a valuable instructional innovation with the potential to enhance the quality of mathematics learning. This study provides empirical evidence to inform the development of culturally responsive and context-based learning resources that support meaningful mathematics education.
