The gap between the theory of plane geometry and real-life contexts occurs because the media often used only teach procedurally, resulting in weak conceptual understanding among students. Based on this, this research aims to develop a digital puzzle based on traditional houses that is suitable and practical for use as a virtual manipulative medium to bridge contextual understanding toward conceptual understanding. This research used a Research and Development (R&D) design and the 4-D model (define, design, develop, and disseminate) with interview guidelines and feasibility and practicality questionnaires as instruments, which were administered to 25 fourth-grade elementary school students. The results of validation by content and media experts indicate a very feasible category with feasibility percentages of 88% and 97.5%. This media is considered very practical to use, with a practicality percentage of 81.7%. These findings show that Digital Puzzle Media based on Traditional Houses is well-suited for teaching plane geometry in elementary school.

This research aims to develop Augmented Reality (AR) learning media integrated with the local culture of Kaliurang that is feasible and practical to use. This research approach uses a quantitative and qualitative approach, also known as a mixed method, with a research and development (R&D) design model 4-D consisting of four stages: define, design, develop, and disseminate. Data collection was conducted through interviews and questionnaires. The selection of subjects was carried out through random sampling with a population of sixth-grade students. The sample used in this study consisted of 25 sixth-grade students from SD Negeri Umbulharjo 2 over 2 months. The analysis of interview data was conducted descriptively, while the questionnaire data used descriptive statistical analysis. The analysis results found the need for the development of learning media, which was subsequently assessed for feasibility with an average score of 3.93 or 98.43%, categorized as "Very Feasible" by subject matter experts, and an average score of 4 or 100%, categorized as "Very Feasible" by media experts. The practicality test received an average score of 3.6 or 90%, classified as "Very Practical" by the students. The findings indicate that Augmented Reality (AR) integrated with the local culture of Kaliurang is well used as a learning medium for spatial geometry with the utilization of technology in the classroom at the elementary school level to support the understanding process of students. This research contributes to the development of innovative learning media integrated with the local culture of Kaliurang, which replicates the improvement of mathematics learning quality. Also, it provides a foundation for further research and practical application in the field of education.

21st-century learning demands integration between technology, pedagogy, content, and cultural context to make the learning process more meaningful, reflective, and inclusive. This research aims to analyze the needs of elementary school students and the readiness of teachers in implementing TPACK-CRT-based learning and to develop a conceptual design for TPACK-CRT learning as an integrative framework. The research employs a mixed-methods approach, combining quantitative and qualitative elements, involving 40 elementary school students and 3 teachers. Data was collected through questionnaires and the synthesis of TPACK and CRT theories, which were then analyzed using descriptive analysis and conceptual framework building. The results indicate that both student needs and teacher readiness fall into the high category; however, there are differences in orientation: students demand more contextual use of technology, while teachers demonstrate higher readiness in pedagogical and affective aspects. Based on the synthesis results, a conceptual design for TPACK-CRT learning was developed, comprising four main phases: contextual orientation, meaningful technology integration, cultural interaction and collaboration, and humanistic reflection and relevance. This research contributes to strengthening the theoretical framework of TPACK-CRT integration and provides practical guidance.
