Pemanfaatan media berbasis ICT menghadirkan pembelajaran kontekstual belum optimal oleh guru. Salah satu penyebabnya terbatasnya kemampuan mendesain konteks nyata sebagai objek. Guru menerapkan pembelajaran konvensional karena belum mampu menghadirkan pembelajaran kontekstual walaupun mereka mampu menggunakan alat komunikasi yang canggih. Observasi menunjukkan bahwa 100% guru SD kelas 1 di Kab Siak sudah menggunakan alat komunikasi canggih, namun hanya 13,6% yang mampu memanfaatkannya untuk mendesain media pembelajaran ICT. Rasional ini mendasari kami TIM PKM Prodi Pendidikan Matematika bekerjasama dengan Dinas Pendidikan dan Kebudayaan Kab.Siak menyelenggarakan workshop pemberdayaan guru SD kelas I mengembangkan media pembelajaran ICT. Data pengabdian adalah respon pelaksanaan PKM yang dikumpulkan melalui angket dan dianalisis secara deskriptif. Berdasarkan analisis data diperoleh: (1) sebanyak 80% peserta menyatakan materi workshop sesuai kebutuhan dalam pengembangan media ICT; (2) 76% menyatakan kegiatan workshop memberikan penguatan dan wawasan dalam pengembangkan media ICT; dan (3) 76% menyatakan kegiatan workshop memberikan pengalaman baru dalam pengembangan media ICT.

The learning process in the classroom can be a trigger for low Mathematical Literacy Ability (KLM) of students so that improving the learning process and increasing students' KLM through the application of the Problem Based Learning (PBL) model is the purpose of this study. The research conducted was Classroom Action Research with two cycles on 35 students of class VIII-3 SMP Negeri 5 Pekanbaru. Data acquisition through learning device instruments (teaching modules equipped with teaching materials, LKPD, Remedial and Enrichment) and data collection instruments (observation sheets and student KLM test devices). The CAR cycle process was carried out in two cycles, covering four stages (planning, action, observation, and reflection) showing an increase in the average score of students' KLM from 54.46 in cycle I to 74.06 in cycle II. These results indicate that through the application of PBL, it can improve the learning process and increase the KLM of students VIII-3 SMP Negeri 5 Pekanbaru.

Perubahan pelaksanaan kegiatan pembelajaran yang semula dilakukan secara tatap muka harus dilakukan secara daring akibat munculnya virus Covid-19. Pelaksanaan pembelajaran daring sampai saat ini masih memiliki kekurangan di beberapa hal, seperti pencapaian kemampuan berpikir kreatif matematis yang belum optimal akibat kurangnya keterlibatan mahasiswa dalam kegiatan belajar mengajar. Hal ini menyebabkan, mahasiswa memerlukan bahan ajar seperti e-LKM yang tidak hanya bisa meningkatkan aktivitas mahasiswa tetapi juga kemampuan berpikir kreatif matematis. Jenis penelitian yang dilakukan adalah penelitian kualitatif deskriptif dengan instrumen penelitian berupa es kemampuan berpikir kreatif matematis, kuesioner, pengamatan, analisis bahan ajar, dan wawancara. Hasil penelitian menunjukkan bahwa mahsiswa membutuhkan e-LKM yang memuat petunjuk, kegiatan, atau langkah kerja, dapat digunakan secara mandiri dimanapun dan kapanpun, serta dapat meningkatkan aktivitas mahasiswa dalam belajar sekaligus meningkatkan kemampuan berpikir kreatif matematis.

The limited availability of supplementary mathematics learning resources aligned with the 2013 Curriculum motivated this study. The objective was to develop learning tools comprising a syllabus, lesson plans, and student worksheets on the topics of quadrilaterals and triangles for seventh-grade SMP/MTs students, using an experiential learning approach to enhance their creative thinking abilities. This research employed the 4D development model, consisting of the define, design, develop, and disseminate phases. Data were collected through questionnaires, observations, and interviews. The research instruments included validation sheets and practicality questionnaires. Expert validation indicated high levels of validity, with average scores of 3.56 for the syllabus, 3.70 for the lesson plans, and 3.67 for the student worksheets. Student worksheets were also found to be highly practical, as reflected in student response scores of 3.48 in large group trials and 3.51 in small group trials. These findings confirm that the developed mathematics learning tools are both valid and practical for use by seventh-grade students in SMP/MTs.

Mathematical communication skills are essential in helping students express, interpret, and solve mathematical problems. However, these skills are often underdeveloped due to a lack of targeted test instruments aligned with relevant mathematical content. This study aims to develop a valid and reliable test instrument to measure mathematical communication skills in the context of three-variable linear equations and two-variable linear inequalities. Using a development research approach with preliminary and formative evaluation stages adapted from Tessmer's model, the instrument was systematically designed, validated, and tested. Data were collected through expert reviews, student responses, and field testing involving 30 participants. Internal validation results indicated a very high validity score (92.80%), while field testing showed that 12 of the 13 developed items were externally valid. The reliability coefficient was 0.80, categorized as very high. The final test set included one easy item, nine medium items, and two difficult items, with discriminating power ranging from sufficient to very good. These findings demonstrate that the developed test instrument is both valid and reliable, and it effectively assesses mathematical communication skills with an appropriate balance of difficulty and item discrimination.

This study aims to develop a Student Worksheet (LKPD) based on Project Based Learning (PBL) for the topic of Systems of Linear Equations in Two Variables (SPLDV) that facilitates the Mathematical Problem-Solving Ability (KPMM) of eighth-grade junior high school (SMP/MTs) students. The developed product is expected to meet the criteria of validity and practicality. The subjects of this study were six eighth-grade students from SMP Negeri 2 Sabak Auh during the even semester. This research employed the Research and Development (R&D) method, with data collection carried out using a practicality questionnaire. The product trial was conducted on a small scale involving six students. The validation results from two expert lecturers and one practitioner showed a validity level of 96.34%. Meanwhile, the practicality level—assessed based on aspects of appearance, language, learning material, problem-solving ability, and ease of use—reached 86.68%. It can thus be concluded that the PBL-based LKPD on the SPLDV topic developed in this study meets the criteria of being valid and practical for use in learning activities aimed at enhancing students’ Mathematical Problem-Solving Ability.

The low mathematical problem-solving abilities of Indonesian students can be seen from the PISA test results, which show that Indonesian students are ranked 72nd out of 78 countries, with an average score of 394 in 2018. Using Problem-Based Learning, this classroom action research seeks to improve the learning process and increase students' mathematical problem-solving abilities. This research was attended by 41 students with various skill levels from class VIII 3 of SMP Negeri 17 Pekanbaru. This research was divided into two cycles, each consisting of four stages: preparation, implementation, observation, and reflection. Research instruments include learning tools and instruments for collecting data. The KPMM test instruments and observation sheets are data collection instruments, while the syllabus, learning implementation plans, and student worksheets are learning tools. Data from observation sheets and mathematical problem-solving ability tests were examined using descriptive analysis techniques. From cycle I to cycle II, the learning process, according to observation data, experienced improvement. In cycle II, the average value of students' mathematical problem-solving abilities increased from 55.97 in cycle I to 81.09. By implementing Problem Based Learning in the learning process, the mathematical problem solving abilities of class VIII3 students at SMP Negeri 17 Pekanbaru have increased and improved their learning process. So researchers highly recommend this learning model in improving the learning process and increasing students' KPMM.
