Abstract

Penelitian ini bertujuan untuk mengembangkan media pembelajaran E-Comic berbasis Realistic Mathematics Education terhadap kemampuan pemecahan masalah pada materi Sistem persamaan linear tiga variabel. Penelitian ini merupakan penelitian Research and Development (R&D) dengan menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Teknik pengumpulan data berupa teknik komunikasi tidak langsung dan teknik pengukuran, dengan alat berupa lembar validasi ahli, angket kepraktisan, dan soal posttest. Sampel penelitian yaitu kelas X A yang terdiri dari 36 siswa. Teknik analisis data yang digunakan mencakup analisis kevalidan, kepraktisan, dan keefektifan. Hasil penelitian menunjukkan bahwa media E-Comic berbasis Realistic Mathematics Education yang dikembangkan mencapai kategori sangat valid dengan persentase kevalidan 89,23%, sangat praktis dengan persentase kepraktisan 90,44%, dan sangat efektif dengan persentase keefektifan sebesar 83,33%. Dengan demikian, media E-Comic berbasis Realistic Mathematics Education layak digunakan dalam proses pembelajaran matematika di sekolah.

Abstract

Students' problem-solving ability on integer arithmetic operations is still relatively low, one of the causes is the uniform learning and lack of attention to the differences in students' learning needs. This study aims to determine the effect of differentiated learning assisted by a number line board on the problem-solving ability of seventh-grade students on integer arithmetic operations at SMP Negeri 08 Satap Simpang Hulu. The study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. The research sample consisted of two classes, namely the experimental class and the control class. Data were collected through essay tests compiled based on Polya's problem-solving indicators. Data analysis was carried out through analysis prerequisite tests, independent t-tests, and effect size calculations. The results showed a significant difference between the problem-solving abilities of students in the experimental class and the control class with a significance value of 0.001 (<0.05). The average posttest score of the experimental class was higher than that of the control class. In addition, the effect size value of 0.915 indicated a large influence. These findings confirm that differentiated learning assisted by a number line board is effective and practically meaningful in improving students' problem-solving abilities.

Abstract

Pulau Lemukutan menghadapi peningkatan volume sampah akibat aktivitas pariwisata dan konsumsi masyarakat. Minimnya sarana pengelolaan sampah serta rendahnya kesadaran ekologis menyebabkan sebagian besar warga masih membuang sampah ke laut atau membakarnya di sekitar pemukiman. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesadaran dan kemampuan masyarakat Pulau Lemukutan, Kalimantan Barat, dalam mengelola sampah rumah tangga melalui pendekatan berbasis data dan penerapan konsep matematika sederhana. Metode yang digunakan adalah Participatory Action Research (PAR) yang melibatkan tiga tahap utama: perencanaan, tindakan, dan refleksi. Kegiatan dilaksanakan di Pulau Lemukutan, Kalimantan Barat dengan peserta sebanyak 22 orang. Hasil kegiatan menunjukkan pengukuran kemampuan awal (pre-test) hanya 27% peserta memahami cara mencatat volume sampah rumah tangga secara sistematis. Setelah pelaksanaan kegiatan, hasil post-test menunjukkan peningkatan hingga 86% peserta yang mampu melakukan pengukuran dan analisis data sederhana. Hal ini menunjukkan adanya peningkatan signifikan dalam kemampuan literasi numerasi peserta. Pendekatan ini terbukti efektif dalam memperkuat literasi numerasi dan kesadaran ekologis masyarakat.

Abstract

The mathematics learning process can be carried out by using and utilizing social phenomena, culture, and other aspects. In the past and currently, mathematics has developed in culture and society, even integrating culture with mathematics. Therefore, it is necessary to involve existing phenomena to overcome various existing problems, including mathematical problems. Therefore, it is necessary to teach mathematics in schools by depicting the context of the origin of mathematical ideas by utilizing culture so that it becomes meaningful learning for students, in this case called ethnomathematics. This short article tries to examine Ethnomathematics Design. In Statistical Analysis Content (Numeracy Literacy Development Study). The method used in this research is ethnography with a qualitative approach. The research results show that the development of ethnomathematics design can go through the definition stage to the initial development stage. From this development stage, an ethnomathematics design in statistical analysis content was produced. The design of ethnomathematics in statistical analysis content is a must-see for the philosophical value of ethnomathematics in its development.

Abstract

This study aims to analyze students' numeracy literacy skills in solving Minimum Competency Assessment (AKM) problems based on their cognitive styles, focusing on reflective and impulsive cognitive styles. The research employs a qualitative descriptive method, enabling an in-depth exploration of students' numeracy literacy abilities at MTs Negeri 01 Pontianak. Data collection techniques include AKM tests, the Matching Familiar Figure Test (MFFT), and interviews. The findings indicate that a reflective cognitive style significantly influences students' ability to solve AKM problems. Students with high numeracy literacy skills meet all numeracy literacy indicators. Meanwhile, students with moderate numeracy literacy skills fail to meet one indicator, namely interpreting. Students with low numeracy literacy skills can only fulfill one indicator, namely formulating. On the other hand, the impulsive cognitive style also affects how students approach AKM problems. Students with high numeracy literacy skills fulfill all numeracy literacy indicators. In contrast, students with moderate numeracy literacy skills meet only one indicator, namely applying. Students with low numeracy literacy skills fail to meet any of the indicators. This research highlights the importance of developing learning strategies that consider students' cognitive styles to enhance their numeracy literacy skills.
