The development of android learning media becomes one of the alternatives in learning, especially in circle materials. The purpose of this research is to produce android-based learning media on valid and practical circle material. This type of research is development research with the ADDIE development model. The research subjects consisted of 17 students. This research data is obtained from questionnaires, interviews, and documentation. This research produces: (1) Learning media that are classified as valid based on validator comments and suggestions, (2) Learning media that are relatively practical based on the results of student comments and suggestions on questionnaires and interviews.

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.

E-Modules are a form of independent learning media designed to cover a specific topic or material. This study aims to develop Canva-based mathematics learning media on the material of flat-sided solid shapes with a guided discovery approach that has a level of validity, practicality, and potential effects on improving students' conceptual understanding. The type of research applied is design research with a development study type, using the Tessmer procedure which includes two main stages, namely the preliminary stage and the prototyping stage through a formative evaluation process, which consists of self-evaluation, one-to-one, expert reviews, small group, and field test. The material in the e-module is arranged based on guided discovery indicators, while the evaluation tool is developed referring to the conceptual understanding indicators. Data collection techniques include interviews, tests, validation sheets, and questionnaires. The research subjects are grade VIII junior high school students. The results of the study indicate that the developed learning media has met the valid criteria based on the results of expert validation, practicality according to the results of student response questionnaires, and has a potential effect in improving students' mathematical conceptual understanding abilities.

This research was motivated by the low achievement of Indonesian students in the assessment of PISA problems and the Islamic context that is familiar to students. The purpose of this research was to produce valid and practical PISA-like mathematics problems using Islamic context in junior high school and to find out the potential effect of the problem on mathematical literacy ability. The subjects of this study were students of the Ninth grade in one of Junior High School, in South Sumatera, Indonesia.Furthermore, the methodology used was design research with the type of development study. The validity was obtained based on the assessment of the validator (expert) regarding the content, construct, and language used and student work in the one-to-one phase. Meanwhile, the practicality can be seen from the work of students in the small group phase where students can understand the meaning or language of the questions. Furthermore, the potential effect can be seen from the strategy of students in working on the questions during the field test. In this case, the potential effects that arise were mathematical communication ability, mathematical representation ability, and ability of devising strategies for solving problems, as well as mathematization ability.

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.

Mathematical problem-solving ability is a core competency in mathematics education and a central focus of competency-based assessment. With the rapid advancement of digital technology, assessment websites have increasingly been utilized to measure and support students’ problem-solving skills. However, systematic studies that synthesize their characteristics, approaches, and contributions remain limited. This study aims to systematically review the literature on the use of assessment websites in enhancing students’ mathematical problem-solving abilities. A Systematic Literature Review (SLR) was conducted following PRISMA guidelines. Relevant articles were retrieved from Google Scholar and Scopus using keywords related to assessment websites and mathematical problem-solving. The inclusion criteria focused on websites that provide mathematical problems and allow students to access their results. The selected studies were analyzed thematically to identify assessment types, key website features, problem-solving frameworks, and their contributions. The findings indicate that assessment websites effectively support students’ problem-solving abilities, particularly through the provision of non-routine problems and immediate feedback on students’ work. The predominant framework identified is Polya’s problem-solving stages. These findings highlight the importance of developing digital assessment platforms that foster authentic and sustainable problem-solving skills in mathematics education.

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
