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

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 systematically examine how and under what conditions ethnomathematical approaches contribute to the development of students’ numeracy skills in mathematics education. Although ethnomathematics has been widely studied, there remains a lack of systematic synthesis focusing specifically on its impact on numeracy outcomes within diverse instructional contexts. This study adopts a Systematic Literature Review (SLR) approach guided by the PRISMA 2020 framework to ensure methodological transparency and rigor. Relevant studies were identified from multiple academic databases, including Google Scholar, Semantic Scholar, Crossref, SINTA, and DOAJ, supported by the Publish or Perish tool. Through a structured selection  process involving identification, screening, eligibility assessment, and inclusion, 20 peer-reviewed articles were analyzed based on predefined criteria. The findings reveal that ethnomathematical approaches can enhance students’ numeracy by embedding mathematical concepts within culturally meaningful contexts, thereby strengthening conceptual understanding and problem-solving abilities. However, the effectiveness of this approach is not uniform and is strongly influenced by instructional design, the authenticity of cultural integration, and teacher pedagogical competence. This study contributes to the field by clarifying the conditions under which ethnomathematics supports numeracy development and by offering a more nuanced understanding beyond general effectiveness claims. The findings provide a foundation for developing culturally responsive numeracy instruction and suggest directions for future research, particularly in terms of experimental validation and cross-contextual analysis.

Abstract

The persistent challenge of developing students’ mathematical problem-solving ability highlights the need for instructional approaches that move beyond procedural learning toward meaningful and contextually grounded understanding. This study investigates the effectiveness of integrating ethnomathematics within a Problem-Based Learning (PBL) framework to enhance students’ mathematical problem-solving ability. A quasi-experimental design with a nonequivalent control group was employed involving 64 ninth-grade students at SMP Negeri 1 Bajawa, Indonesia. The experimental group was taught using ethnomathematics-based PBL, while the control group received conventional instruction. Data were collected through validated essay-based tests and analyzed using descriptive statistics and an independent samples t-test. The findings reveal that the experimental group achieved a substantially higher mean posttest score (84.06) compared to the control group (72.44), with the difference proven to be statistically significant (p < 0.05). Furthermore, the large effect size indicates that the intervention produced not only statistical significance but also meaningful educational impact. These results suggest that the integration of cultural context within a structured problem-based learning environment facilitates deeper cognitive engagement, enabling students to interpret, represent, and solve mathematical problems more effectively. The study advances existing literature by demonstrating that ethnomathematics functions as a cognitive catalyst when embedded within inquiry-driven pedagogy, rather than as a supplementary contextual element. In conclusion, ethnomathematics-based PBL offers a robust and contextually responsive instructional model that supports the development of higher-order thinking skills and provides a viable pathway for improving the quality of mathematics education.
