The study aimed to produce PISA-like mathematics problems with the Islamic ethnomathematics approach that were valid and practical. A development study with formative evaluation was used as the method in this study with 32 9th-grade students as the subjects at one of the junior high schools in Palembang, South Sumatra province, Indonesia. There are five phases: self-evaluation, expert review, one-to-one, small group, and field test. Interviews, questionnaires, and tests were used in this study as the instruments to collect the data. The results showed that three experts from the expert review phase assess that 77.78% agree that six PISA-like mathematics problems meet the validity criteria. For the practicality criteria, three students from the one-to-one step set about 77,78% agree, three students from the small group phase assessed about 61,11% strongly agree, and 26 students from the field test phase considered 61,33% agree. This result is supported by the average test result that was classified as a low category. This showed that the results obtained are not optimal because students still did not understand the problems and had difficulty solving them.

The aim of this study was to investigate the effect caused in learning of finite integral when a lecturer give a problem about finding area below a graph of the function with two partitions which the scale on Cartesian coordinate of x-axis different with y-axis. This research type was descriptively qualitative. The subject of this study was 32 undergraduate students majoring in mathematics education that attend integral calculus class at one universities in Palembang. In this study, the 32 students was formed become 6 groups. Instrument in this study was two problems that discussed by them in group. The data was collected by documentation of students’ worksheet, observation, and interview. The result showed the effect on students, that is, they seen try to construct their mathematics knowledge by themselves first, communicate unexpected ideas before, and can think critically on the given problem. The positive effects showed up because the given problem to them related with some concepts.

Realistics Mathematics Education (RME) is an instructional approach that emphasizes the use of real-world problems and situations in mathematics teaching. This method is believed to significantly enhance students' mathematical literacy, which is crucial for their academic and everyday problem-solving skills. This systematic literature review aims to investigate the impact of RME on students' mathematical literacy by synthesizing existing research findings. A systematic review design was employed, focusing on studies that explore the relationship between RME and mathematical literacy. The Scopus database was utilized for bibliometric analysis, with the search term "mathematical literacy" restricted to article titles. Data extracted included author names, citation counts, titles, publication years, sources, publishers, and document types. The analysis revealed approximately total of 200 publications related to mathematical literacy were found with a total of 10,817 citations, resulting in an average of 54.1 citations per article, indicating a substantial body of research on this topic. Notable trends included the integration of computer-mediated learning and various pedagogical models. The findings suggest that RME is an effective pedagogical approach that promotes students' mathematical literacy through authentic and contextualized learning experiences. This review highlights the necessity of developing educational materials and teaching strategies that prioritize mathematical literacy, thereby enhancing students' proficiency in mathematics and preparing them for real-world applications.

Data hasil penelitian kadang ditemukan berdistribusi tidak normal. Ketika hal itu terjadi, suatu penelitian yang akan menguji dua faktor dapat menggunakan uji ANOVA dua arah tetapi data tidak dapat langsung diolah, karena tidak memenuhi uji asumsi sebagai prasyarat. Oleh karena itu, tujuan pengabdian kepada masyarakat ini adalah untuk memberikan pelatihan dan keterampilan kepada para dosen dalam mengolah data yang berdistribusi tidak normal pada uji ANOVA dua arah dengan interaksi menggunakan software ARTool dan SPSS. Kegiatan pelatihan ini dilaksanakan di UIN Raden Fatah dengan mengundang dosen-dosen FKIP dari empat Universitas yang berada di kota Palembang Metode pelatihan bersifat tutorial. Sebagai bahan evaluasi, angket digunakan untuk mengumpulkan data mengenai alasan peserta mengikuti pelatihan dan tanggapan mereka setelah mengikuti pelatihan. Hasil kegiatan dari pelatihan ini menunjukkan bahwa antusias peserta mengikuti pelatihan dikategorikan tinggi dan respon peserta setelah mengolah data berdistribusi tidak normal pada uji ANOVA dua arah dengan interaksi menggunakan ARTool dan SPSS sebagian besar menyatakan cukup mudah.

Penelitian ini dirancang untuk menghasilkan instrumen evaluasi berbasis kemampuan berpikir tingkat tinggi (HOTS) dalam format soal Two-Tier Multiple Choice pada materi bilangan untuk peserta didik SMP kelas VIII, serta untuk mengetahui tingkat kevalidan instrumen yang dikembangkan. Latar belakang penelitian ini adalah rendahnya capaian nilai TKA matematika di tingkat nasional maupun regional, yang mengindikasikan masih banyak siswa yang belum mampu memahami konsep secara mendalam maupun menyelesaikan soal bertipe HOTS. Penelitian dilaksanakan di SMP Negeri 1 Pemulutan Barat dengan subjek 10 siswa. Pendekatan yang digunakan adalah Research and Development (R&D) dengan model ADDIE yang melewati lima tahapan: Analysis, Design, Development, Implementation, dan Evaluation. Pengumpulan data dilakukan melalui lembar validasi ahli, hasil pengerjaan soal oleh siswa, serta dokumentasi. Data dianalisis secara kualitatif berdasarkan masukan validator dan secara kuantitatif melalui analisis deskriptif persentase. Pengujian validitas butir soal menggunakan korelasi Pearson product-moment pada SPSS Statistics 16. Instrumen mencapai persentase validasi 82% (sangat valid). Hasil uji validitas menunjukkan bahwa seluruh butir soal dinyatakan valid dan uji reliabilitas memperoleh nilai 0,986 yang menunjukkan instrumen memiliki reliabilitas sangat tinggi. Dengan demikian, instrumen layak digunakan untuk mengukur kemampuan berpikir kritis siswa pada materi bilangan.
