Critical thinking ability is a crucial ability in mathematics, both at the elementary, secondary, or college level. However, this critical thinking ability is still low. Therefore, the researchers want to study the problem at what level the students are doing in solving mathematical critical thinking problems. The research method used a qualitative method, with the implementation analyzing students who deal with mathematical critical thinking ability problems. The study was conducted at one of the State Junior High Schools in Kroya District, Indramayu, West Java. As a result of the study, information was obtained about students who could not solve the problems presented in mathematical critical thinking ability problems, so they did not understand which strategies should be used to solve problems that could be solved.

A mosque is a place of worship for Muslims worldwide. The shape of the mosque in each region is different. Along with the times, the mosque has also become one of the objects in cultural acculturation from one area to another, thus creating increasingly diverse shapes and designs in mosques. One of them is the Darussajidin Mosque in Bondan Barat Indramayu. This research aims to determine the ethnomathematics of the Darussajidin Indramayu mosque in designing mathematical activities and the ethnomathematics of the Darussajidin Indramayu mosque on the philosophical meaning of Islamic values. This research was conducted at the Darussajidin mosque, Indramayu, in Bondan Village, Sukagumiwang District, Indramayu Regency. The subjects in this study were DKM mosques, caretakers, community leaders, and cultural observers, while the object in this study was the Darussajidin Indramayu mosque. This research is qualitative research with an ethnographic approach. Observation, interviews, and documentation collected data. The instruments used are observation guidelines, interview guidelines, and documentation tools.

This research aims to analyze the increase in geometric thinking skills after using the Learning Cycle assisted by an interactive Geometry Book. The research design used is an experiment Design. In addition, the participants in this research were students in class VIII B at a private school in Indramayu Regency. Apart from that, the test instrument in this research is a test sheet in the form of a description. Next, the data obtained from the pre-test and post-test were analyzed statistically using the paired samples t-test. Based on the research results, it shows that the N-gain score shows an average value of 0.8903 or 89.03%, which is included in the high category. Furthermore, based on the normality test of the pre-test and post-test data, it shows that both data are normally distributed. Apart from that, based on the results of the paired samples test calculation, the Sig value is known. (2-tailed), namely 0.000 < 0.05, then Ho is rejected and Ha is accepted. Therefore, this study concludes that there is a difference in the average increase in students' geometric thinking abilities before and after using the interactive learning cycle assisted by interactive geometry books.

This research uses a realistic ethnographic design to examine the culture of mathematical thinking in determining the match between partners for marriage in the Losarang-Indonesian Dayak community. Data were collected through field notes, in-depth interviews, and observation. Ethnomathematics as a research genre reveals important universal elements of mathematical activity, while ethnomodelling reflects ideas and the practice of community mathematics through ethical, emic, and dialectical approaches. The findings of this research indicate that ethnomathematically, the Losarang-Indonesian Dayak community have used formal language on mathematical principles to develop a knowledge system capable of sorting, pairing, calculating, and comparing the suitability of partners based on birth. Ethnomodelling is a relevant mathematical idea and concept related to arithmetic operations, sets, relations, functions, and number comparisons. Furthermore, the implication of this research is to produce didactic situations to teach the concepts of arithmetic operations, sets, relations as well as functions, and number comparisons. The didactic situation of the customary patterns of the Losarang-Dayak community can also be presented in mathematics teaching materials based on local culture. Therefore, the successful conduction of this research can enrich the repertoire of developing school mathematics learning that focuses on local culture.

Teachers play a determining role in students' success in achieving learning goals. Therefore, Pedagogical Content Knowledge is an ability that teachers and prospective teachers must have. This research aims to describe the Pedagogical Content Knowledge profile of prospective mathematics teachers in collaborative online learning, especially in courses evaluating mathematics learning processes and outcomes. This research is descriptive qualitative research. Prospective mathematics teacher students who contracted courses in evaluating the process and results of mathematics learning from Wiralodra University and Nahdlatul Wathan University of Mataram, were the subjects of this research. The instruments used in this research were a test of understanding the concept of evaluating mathematics learning processes and outcomes, questionnaires, and learning documentation via the Phytagoras LMS. The data analysis techniques used include data reduction stages, data presentation, and drawing conclusions. Based on the research results, it was found that students in the mathematics learning process and outcome evaluation course whose lectures were held collaboratively online had a very good Pedagogical Content Knowledge profile and gave a positive response to the implementation of collaborative online learning.

Hambatan epistemologi muncul akibat keterbatasan pengetahuan siswa dalam konteks tertentu, meliputi hambatan konseptual, prosedural, dan teknik operasional, yang terkait dengan cara siswa memproses informasi dan gaya kognitifnya. Penelitian deskriptif kualitatif di SMA Negeri 2 Indramayu menggunakan angket MFFT, tes kontekstual, dan wawancara yang diikuti oleh 34 siswa dan akan dipilih dua subjek penelitian yang menunjukkan perbedaan signifikan antara siswa reflektif dan impulsif. Siswa reflektif (NL/RE1) mengalami 0% hambatan konseptual dan prosedural, serta 16,67% teknik operasional, sementara siswa impulsif menghadapi 22,22% konseptual, 55,55% prosedural, dan 50% teknik operasional. Secara keseluruhan, hambatan epistemologi siswa tergolong sedang/cukup tinggi, dengan siswa impulsif lebih rentan mengalami kendala dibandingkan siswa reflektif.

contextual relevance. This study aims to develop Calquemath, an Android-based calculus learning application that integrates architectural elements of the Kyai Syakir Mosque in Wotgalih, Indramayu, as an ethnomathematical context. The media development followed the 4D model, limited to the develop stage. The define stage involved needs analysis, exploration of local cultural potential, and literature review. The design stage included initial media design using Kodular, incorporating content on curved solid geometry (hemisphere, cone, and cylinder) connected to integral concepts. The develop stage consisted of prototype creation and expert validation by two mathematics education lecturers and one mathematics teacher. The validation instrument covered aspects of content feasibility, visual appearance, interactivity, and integration of ethnomathematical context. Validation results indicate that Calquemath falls into the “highly feasible” category as a learning medium, based on expert assessments of visual quality, readability, interactivity, and ease of navigation. Future research is recommended to proceed to the disseminate stage to measure the media’s effectiveness in enhancing students’ understanding of calculus concepts.
