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.

Abstract

The collaborative model-based development of Student Worksheets (LKPD) for Mathematics using the Realistic Mathematics Education (RME) approach aims to improve teachers' ability to design LKPD that are contextual and meaningful, and encourage active student collaboration. This mentoring program is implemented through several stages: identifying teacher needs, training in developing RMR-based LKPD, mentoring in the design and testing process, and reflecting on implementation results. The methods used in this activity include workshops, group discussions, observations, and evaluation of teacher work. The mentoring program results indicate that teachers gained an increased understanding of PMR principles and improved their ability to develop LKPD that emphasize active student involvement in real-world problem-solving through group collaboration. Furthermore, the resulting LKPD were deemed valid and suitable for use based on expert assessment and positive student feedback. Thus, this mentoring program contributes to improving the quality of mathematics learning materials in schools and supports the implementation of more innovative, collaborative, and contextual learning.

Abstract

Strengthening students’ numeracy competence and higher-order thinking skills has become an important priority in contemporary mathematics education, particularly within curriculum reforms that emphasize analytical reasoning and meaningful problem solving. However, assessment practices in many mathematics classrooms still focus primarily on procedural knowledge and lower-order cognitive processes, limiting opportunities for students to demonstrate deeper mathematical understanding. This situation highlights the need for assessment instruments that integrate numeracy development with higher-order thinking skills (HOTS) in authentic learning contexts. This study aims to develop a HOTS-based formative numeracy assessment instrument for seventh-grade students on the topic of fractions and to evaluate the feasibility of the developed instrument for classroom use. The research employed a research and development approach using the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The study involved 64 students from classes VII A and VII B at SMP Negeri 2 Bajawa. Data were collected through interviews, classroom observations, expert validation sheets completed by mathematics teachers, and student response questionnaires. The findings indicate that the developed instrument meets the criteria of validity and practicality for mathematics learning, with expert validation reaching 82.85 percent, teacher responses 87.77 percent, and student responses 84.92 percent. The assessment tasks encourage contextual problem solving and analytical reasoning related to fraction concepts.

Abstract

This study aims to thoroughly analyze the role of ethnomathematical approaches in improving students' numeracy skills based on various published research results. This study uses the Systematic Literature Review (SLR) method by utilizing secondary data source in the from of scientific articles obtained from various academic data such as Google Scholar, Semantic Scholar, Crossref, SINTA, DOAJ with the supporting application Publish or Perish. The process of searching and selecting articles was carried out systematically through the stages of identification, screening, and quality evaluation according to the PRISMA procedure, so that 20 articles that met the inclusion criteria were obtained. Data from the selected articles were then analyzed qualitatively descriptively to identify consistent patterns of findings. The results of the study show that the integration of cultural elements in mathematics learning through an ethnomathematical approach makes a positive contribution to improving students' numeracy skills. Learning that relates mathematical concepts to the local cultural context has been proven to help students understand concepts in a more meaningful and contextual way. However, the implementation of this approach is still limited to specific cultural contexts and depends on teachers' creativity in developing relevant learning media and strategies
