Abstract

Purpose of the study: This study aims to develop a didactical design based on Research and Development to improve junior high school students’ conceptual understanding of cones and cylinders by addressing their learning obstacles through structured instructional materials. Methodology: This study employed a Research and Development approach adapted from Borg and Gall and Sugiyono models. The research involved eighth-grade students, using interviews, observation sheets, validation instruments, and questionnaires. Data were analyzed using descriptive qualitative and quantitative methods with Likert scale scoring. Expert validation involved mathematics education lecturers and teachers. Small-scale and large-scale trials were conducted to evaluate the developed module’s feasibility and effectiveness in mathematics learning on cones and cylinders. Main Findings: The developed didactical design module showed significant improvement after expert validation and revision. The results indicated very good criteria in content quality, language clarity, and media design. Student responses in small-scale and large-scale trials reached 90–94%, categorized as very good. The module effectively reduced learning obstacles and improved students’ conceptual understanding of cones and cylinders. The findings confirm that the instructional material is valid, practical, and effective for classroom implementation. Novelty/Originality of this study: This study develops a didactical design module integrating learning obstacle analysis specifically for cones and cylinders using an R&D approach. The innovation lies in its structured adaptation of students’ cognitive difficulties into instructional design. It contributes a context-specific mathematics learning module that enhances conceptual understanding and provides a practical model for developing geometry-based teaching materials.

Abstract

Purpose of the study: This study aims to explore students’ mathematical problem-solving ability based on the Wankat and Oreovocz theory by identifying how students perform across each stage of the problem-solving process in order to provide a comprehensive description of their abilities. Methodology: This study employed a qualitative descriptive approach using purposive sampling, involving six students from class VII E at SMP Negeri 19 Bandar Lampung. Data were systematically collected through observation, written essay tests, and semi-structured interviews, and analyzed using data reduction, data display, and conclusion drawing with triangulation techniques for validation purposes. Main Findings: The results show that most students achieved high problem-solving ability, with 59.26% in the excellent category and 25.93% in the good category. Students performed best at the motivation stage (“I Can”) but showed lower performance in planning, evaluation, and generalization stages. High-performing students completed all stages systematically, while lower-performing students experienced difficulties beyond initial stages, especially in selecting appropriate strategies and verifying solutions. Novelty/Originality of this study: This study offers a detailed stage-based analysis of students’ mathematical problem-solving ability using the Wankat and Oreovocz framework, focusing on students’ actual performance rather than instructional strategies. It provides new insights into specific difficulties at each stage, particularly in planning, and contributes to advancing knowledge on how structured problem-solving frameworks can be applied to analyze students’ cognitive processes.
