Abstract

Research on the ontogenic and didactical obstacles vocational high school students face in solving counting rule problems has been limited. Ontogenic obstacles involve students' readiness, while didactical obstacles concern the sequence and presentation of instructional materials. Therefore, teachers must consider both when developing effective materials. This research aims to describe the ontogenic and didactical obstacles experienced by vocational high school students in solving counting rule problems. The participants of this study were 24 grade XII students from a public vocational high school in Cirebon. Using a Didactical Design Research (DDR) approach, this qualitative study focuses on the prospective analysis stage, examining these obstacles. The research instrument included five diagnostic essay questions and interview guidelines. The results revealed that students encountered instrumental-type ontogenic obstacles, particularly in understanding factorial operations. Additionally, didactical obstacles arose from incomplete teaching materials and improper notation, which led to learning barriers. This research offers valuable insights for teachers and researchers in designing instructional materials, especially for counting rules in vocational schools.

Abstract

This study employs a hermeneutic phenomenological approach to explore students' epistemological obstacles in solving permutation and combination problems, with the goal of supporting the development of more effective teaching materials. The research involved 24 12th-grade high school students (14 males and 10 females) and used qualitative methods. Data were collected through five diagnostic essay questions and semi-structured interviews to identify epistemological obstacles in combinatorics. Students’ written responses and interview transcripts were analyzed and interpreted to uncover the underlying obstacles. The findings revealed several epistemological obstacles: (1) students were unable to identify all possible answers from a given problem; (2) students could not differentiate between problems requiring the concept of permutation and those requiring the concept of combination; (3) students struggled to solve problems that differed from the example problems provided; and (4) challenges in formulating a complete solution when faced with multiple conditions, despite being able to calculate partial results. These insights suggest that teachers and future researchers should consider students' epistemological obstacles when designing instructional materials, particularly for topics in combinatorics such as permutations and combinations. Developing learning resources based on these findings may enhance conceptual understanding and problem-solving skills among students.

Abstract

Purpose - This study aims to identify effective media, instructional strategies, or teaching models that can bridge conceptual understanding and mathematical representation in mathematics education. It was motivated by the persistent gap observed between students' conceptual grasp and their ability to translate concepts into mathematical forms, which hinders problem-solving competence. Methodology - A Systematic Literature Review (SLR) was conducted following the PRISMA 2020 guidelines. Literature was sourced from Google Scholar and DOAJ databases, focusing on publications from 2015 to 2025. The review process resulted in seven articles meeting the inclusion criteria. Data analysis involved thematic synthesis of instructional approaches and their reported effectiveness in bridging conceptual and representational understanding. Findings - The review found that the relationship between conceptual understanding and mathematical representation is closely linked but not automatic, depending significantly on the instructional strategies employed. Effective approaches identified include the Concrete–Pictorial–Abstract (CPA) model, GeoGebra media, SAVI strategy, Joyful Problem-Based Learning (JPBL), and Role-Playing Game (RPG)-based learning, which enhance engagement and facilitate conceptual-visual connections. These findings imply the need for intentional instructional designs that integrate conceptual and representational aspects in mathematics learning. Novelty - This study contributes by systematically mapping and synthesising diverse strategies and media specifically targeting the integration of conceptual understanding with mathematical representation, an area underexplored in prior reviews. Significance - The results are valuable for mathematics educators, curriculum developers, instructional designers, and educational policymakers seeking evidence-based practices to improve mathematics teaching and learning outcomes.

Abstract

In the era of modernisation, conceptual understanding and mathematical representation are key components of education. However, many students still encounter difficulties in understanding and accurately representing rectangular prisms. This study addresses the need for innovative learning by examining students' experiences in understanding and representing rectangular prisms through a Role-Playing Game-based educational game and module. This study employed a qualitative method to understand the experiences of 17 eighth-grade junior high school students in learning rectangular prisms through an RPG game and a supplementary module. Data were collected through observation, module analysis, and documentation and then analysed thematically. The findings revealed that while some students found it easier to grasp concepts through visual exploration, others struggled to apply these concepts flexibly beyond the game. Students who actively engaged in gameplay demonstrated a deeper understanding and were better able to make meaningful conceptual connections. Although verbal representation improved significantly, symbolic representation remained challenging for some students. This study emphasises the importance of designing educational games that support conceptual understanding and representation skills. The implications of this study highlight the need for the development of interactive learning media that can facilitate students' conceptual connections and foster their mathematical representation skills.

Abstract

This research is motivated by the low interest and learning outcomes of fifth grade students of SDN Wanacala on Cultural Heritage material in the Natural and Social Sciences (IPAS) subject. Learning that is still dominated by conventional methods tends to be less able to attract students' attention, resulting in decreased motivation and enthusiasm in participating in the learning process. To overcome these problems, this study aims to develop Mystery Box media on Cultural Heritage material for fifth grade elementary school students and evaluate its effectiveness in improving students' cognitive learning outcomes. The research employed the Research and Development (R&D) method with the ADDIE development model, encompassing Analysis, Design, Development, Implementation, and Evaluation stages. The subjects were fifth-grade students at SDN Wanacala. Data collection instruments included media and material expert validation sheets, student and teacher response questionnaires, and learning outcome tests. The results indicated that the developed Mystery Box media was categorized as highly feasible, with validation scores of 95.4% from media experts and 91.4% from material experts. Positive responses were also shown by teachers and students, with percentages of 93.8% and 88.8%, respectively. Paired Sample T-Test analysis yielded a significance value of 0.000, indicating a significant difference between pretest and posttest scores. N-Gain calculations showed an improvement in learning outcomes within the medium category, specifically 0.688 for large scale. Therefore, the Mystery Box media is effective and suitable for use in teaching the Cultural Heritage material in IPAS to enhance the cognitive learning outcomes of fifth-grade students at SDN Wanacala.
