Rendahnya capaian literasi matematika siswa Indonesia pada asesmen nasional maupun internasional menunjukkan perlunya peningkatan kompetensi guru dalam menyusun soal yang menuntut penalaran tingkat tinggi dan berbasis konteks nyata. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kemampuan guru matematika SMP di Desa Meranjat dalam mengembangkan soal tipe PISA dan Tes Kompetensi Akademik (TKA) berbasis kearifan lokal. Metode pengabdian ini dirancang berdasarkan pendekatan kegiatan PkM berbasis pelatihan dan pendampingan (training and mentoring model), yang menekankan alur sistematis mulai dari sosialisasi, pelatihan, produksi, digitalisasi, hingga implementasi untuk memastikan terbangunnya kompetensi guru secara berkelanjutan.. Sebanyak 33 guru mengikuti kegiatan, dengan analisis pre-test dan post-test digunakan untuk mengukur peningkatan kompetensi. Hasil menunjukkan adanya peningkatan signifikan pada pemahaman guru, dengan kenaikan rata-rata nilai dari 71,62 menjadi 91,17. Selain itu, guru mampu menghasilkan draf soal yang lebih berkualitas, memanfaatkan konteks budaya lokal seperti songket, pertanian, dan kuliner Meranjat, serta mempublikasikannya melalui platform digital, yakni Instagram. Temuan ini menegaskan bahwa pelatihan terarah dan pendampingan berkelanjutan efektif meningkatkan kapasitas guru dalam menyusun asesmen kontekstual, sekaligus mendukung penguatan literasi numerasi siswa di wilayah perdesaan.

This study aims to support students proportional reasoning in comparison problems using Palembang culture as context and PMRI approached. Six students of 7th grade were participated. We used design research as research approach, a Hypothetical Learning Trajectory (HLT) was develop and a set of activities using Palembang culture as context, such as ketek fare, empek-empek price, lempok price. Theoretical development is driven by an iterative process of designing instructional activities, performing teaching experiments and conducting retrospective analysis in order to contribute to Local Instruction Theory (LIT) to support students proportional reasoning in comparison problem. Data collected by making video recording about actual teaching and learning in classroom, collecting students worksheet, giving pretest and posttest, interviewing students. The designed HLT compared Actual Learning Trajectory (ALT) during pilot experiment to analyze whether the students learned or did not learn from what we had designed in the instructional sequence. Retrospective analysis of pilot experiment showed that by using Palembang culture as context can support students proportional reasoning in middle school to solve comparison problems.

This study aims to describe elementary students’ procedural fluency in solving fraction addition problems using the built-in definition fraction media. Fraction operations are often challenging for students, particularly when determining common denominators and applying calculation procedures accurately. These difficulties are commonly associated with weak procedural understanding and limited opportunities to use concrete learning media. This descriptive study involved 30 fourth-grade students from SDN 204 Palembang who had previously learned basic fraction concepts. Data were collected through a written test consisting of three levels of procedural fluency tasks and supported by interviews to explore students’ reasoning processes. The results show that 47% of students were able to solve fraction addition problems with denominators (Level 1), 33% managed tasks involving adjustment of one denominator (Level 2), and only 13% successfully solved problems requiring the determination of the least common multiple of denominators (Level 3). These findings indicate that students’ procedural fluency development is not linear but constrained at transition points from concrete visual manipulation to abstract procedural reasoning. While the built-in definition fraction media effectively supported early procedural stages by strengthening visual–procedural connections, it was less effective in facilitating higher-level abstraction required for complex fraction operations. The study contributes to procedural fluency literature by identifying specific procedural transition points where students begin to experience difficulties.

The 2022 PISA results show that the mathematical literacy performance of Indonesian students remains low. This study aims to describe the mathematical literacy abilities of ninth-grade students through the implementation of Problem Based Learning (PBL) supported by Nearpod in the topic of Systems of Linear Equations in Two Variables (SPLDV). The research subjects consisted of 29 students from MTs Negeri 1 Ogan Ilir. Data were collected through written tests in the form of open-ended questions, as well as interviews. The PBL learning supported by Nearpod was carried out in one meeting prior to the administration of the test. The data were analyzed using triangulation to obtain a comprehensive description of students’ mathematical literacy abilities. The findings indicate that the implementation of PBL supported by Nearpod can enhance students’ mathematical literacy, particularly in the aspect of formulating problems. However, students still encounter difficulties in mathematizing contextual information into mathematical models and performing basic calculations accurately. These findings contribute to efforts to improve the quality of mathematics learning through the integration of problem-based learning and interactive technological tools.

Pembelajaran konsep distribusi Bernoulli masih dirasakan abstrak oleh mahasiswa sehingga diperlukan media konkret yang dapat menjembatani pemahaman antara teori dan pengalaman empiris. Penelitian ini bertujuan mengembangkan media Bernoulli Box berbantuan LKPD untuk mengenalkan konsep dasar Distribusi Bernoulli serta mengetahui validitas dan kepraktisan produk yang dikembangkan. Metode penelitian menggunakan Design Research tipe Development Studies yang meliputi preliminary phase dan prototyping phase melalui self-evaluation, expert review, one-to-one, dan small group. Subjek penelitian yaitu sembilan mahasiswa semester 1 Program Studi Pendidikan Matematika Universitas Sriwijaya yang dipilih secara purposive. Data dikumpulkan melalui walkthrough, lembar validasi, observasi, tes dalam LKPD, wawancara, dan angket kepraktisan, kemudian dianalisis secara deskriptif. Hasil validasi ahli menunjukkan bahwa Bernoulli Box dan LKPD memiliki validitas isi, konstruk, dan bahasa yang baik. Uji one-to-one dan small group menunjukkan bahwa mahasiswa mampu mengikuti aktivitas dalam LKPD secara mandiri dan memahami dua kemungkinan hasil percobaan Bernoulli dengan benar. Hasil angket kepraktisan memperoleh persentase 98,08% yang termasuk kategori sangat praktis. Dengan demikian, media dan LKPD yang dikembangkan layak digunakan sebagai alternatif pembelajaran untuk memperkuat pemahaman konsep Distribusi Bernoulli.
