This study aims to conduct a systematic literature review related to geometric transformation learning using the Indonesian Realistic Mathematics Education (PMRI) approach. The research method employed was a Systematic Literature Review (SLR). The research data consisted of journal articles discussing PMRI-based geometric transformation learning. The article selection criteria included relevance to the research topic, publication in reputable journals, and alignment with PMRI principles. The results indicate that PMRI-based learning can improve students’ understanding of geometric transformation concepts through the use of realistic contexts. Therefore, PMRI can be considered an effective approach for teaching geometric transformation.

This study aims to develop exploration activities for flat shapes (triangles and quadrilaterals) using GeoGebra Classroom, designed to improve conceptual understanding among seventh-grade students. This research is motivated by the low understanding of mathematical concepts, where students often rely on procedural memorization. The study uses the Research and Development (R&D) approach with the 4D model (Define, Design, Develop, Disseminate), focusing on the Develop phase. Data collection instruments include expert validation sheets (content and media), field observation guidelines, and conceptual understanding tests. Data analysis is conducted using both qualitative and quantitative descriptive methods to assess the feasibility of the product. These exploration activities were intentionally designed without the instant presentation of formulas to encourage students to independently construct geometric properties through GeoGebra's dragging feature. The expected outcome of this research is the creation of a valid and practical learning tool that helps students visualize and understand geometric concepts meaningfully

: This study aims to produce e-module teaching materials based on PMRI on polyhedron material for class VIII SMP using the context of the Muara Enim traditional house using the Canva application, as well as to find out whether this e-module is valid, practical, and has a potential effect on problem-solving abilities in students. Learners. The research method used is R&D using Tessmer. The research process consists of two stages: the first preliminary stage, which includes the preparation and design stages, and the second assessment, which is a formative flow that provides for self-evaluation, expert review, one-to-one, small groups, and field tests. Compiled with the PMRI approach and linked to the context of the Muara Enim traditional house, the stages of testing the presentation of e-module teaching materials. The e-module learning materials were given to class VIII students of Junior High School. At this time, it shows that using e-modules in making teaching materials is valid and practical with qualitative analysis. The validity of teaching materials is carried out at the expert review stage using the validator's comments and suggestions—validity aspects in terms of the E-module's content, construction, and language. Practicality is done in the one-to-one, small group, and field test stages by looking at student comments and suggestions. The potential effect is the result of student evaluation tests used in field tests. The developed e-module teaching materials have a possible effect with an accuracy rate of 72.6%, so the e-module is potentially impacting mathematical problems. The researcher suggests that future researchers make the questions in the e-module more varied. Questions vary by providing questions from cognitive levels from C1 to C6.

Tuntutan kurikulum yang mengharuskan siswa memiliki kemampuan kritis dan bernalar yang baik dalam menyelesaikan masalah matematik, mengharuskan guru memiliki kemampuan mendesain pembelajaran, dalam penelitian ini memadukan teknologi dalam lembar kerja peserta didik menjadikan E-LKPD sebagai Solusi yang dapat digunakan dalam proses pembelajaran. Penelitian ini bertujuan menghasilkan E-LKPD materi kubus dan balok menggunakan Pendekatan CTL dengan Konteks Melayu yang valid dan praktis serta memiliki efek potensial terhadap kemampuan matematis siswa. Hasil penelitian memberikan gambaran bahwa ada capaian 61,1 % atau ada 22 siswa kemampuan matematis siswa kategori sangat baik, 19,4 % atau ada 7 siswa kategori Baik, 11,1% atau ada 4 siswa kategori cukup, dan 8,3% atau ada 3 siswa kategori kurang. Sehingga efektivitas E-LKPD berbasis pendekatan Contextual Teaching and Learning (CTL) yang dikembangkan dalam meningkatkan kemampuan pemahaman matematis siswa dapat disimpulkan memberikan efek potensial yang baik terhadap kemampuan pemahaman matematis siswa. Curriculum requirements that require students to have good critical and reasoning skills in solving mathematical problems require teachers to have the ability to design learning. In this study, integrating technology into student worksheets makes E-LKPD a solution that can be used in the learning process. This study aims to produce E-LKPD materials on cubes and blocks using the CTL approach with a valid and practical Malay context that has a potential effect on students' mathematical abilities. The results of the study show that 61,1% or 22 students achieved a very good level of mathematical ability, 19,4% or 7 students achieved a good level, 11,1% or 4 students achieved an adequate level, and 8,3% or 3 students achieved a poor level. Therefore, the effectiveness of E-LKPD based on the Contextual Teaching and Learning (CTL) approach developed to improve students' mathematical comprehension skills can be concluded to have a potentially positive effect on students' mathematical comprehension skills.

This study aims to develop E-LKPD based on the Contextual Teaching and Learning (CTL) Approach on the material of circles with a woven context for grade VIII junior high school students. This development research uses the Tessmer model consisting of a preliminary stage including analysis of students, curriculum, and teaching material needs, while the prototyping stage includes design, validation, and trial of E-LKPD. Data collection was carried out using interview methods, observations, questionnaires, and concept understanding tests. Based on the analysis results, it was found that students still experience obstacles in understanding the concept of circles due to limited context-based teaching materials and the unavailability of a curriculum that supports the integration of local wisdom, such as the use of woven rope. The developed E-LKPD is considered to have met the validity criteria (average score of 89.7%), practical (average score of 84%), and had a potential effect (average score of 88.8%). The CTL approach with a woven context increased students' motivation, involvement, and appreciation of local culture. This study produced an E-LKPD that was suitable for use as an interactive mathematics learning media that was relevant to students' daily lives.
