Abstract

This study addresses the deficiencies in students' mathematical thinking skills. A preliminary assessment of 69 students yielded a mean score of 21.32. The study examined enhancing students' mathematical thinking skills through the Realistic Mathematics Education (RME) model, supported by the ethnomathematics mobile module. This quantitative research employs a quasi-experimental design. The researchers collected data using a mathematical thinking skills test and analyzed it through an independent sample t-test and N-gain test. The findings indicate a significant improvement in the experimental group's posttest mean score, which increased to 80.72, surpassing the control group's posttest mean score of 69.49. The results confirm a significant difference in mathematical thinking skills between students taught using the RME approach with the ethnomathematics mobile module and those instructed through traditional lectures. The pretest-posttest data for the experimental group yielded an N-gain score of 0.59, classified as moderate. The study concludes  that implementing the RME model with the ethnomathematics mobile module effectively enhances seventh-grade students' mathematical thinking skills in data presentation. The findings suggest that the ethnomathematics mobile module should be incorporated into other mathematical topics to support students' learning further.      Keywords: ethnomathematics mobile module, mathematics thinking skills, RME.

Abstract

This research aims to analyze the mathematical reasoning abilities of grade V students at SDN 5 Mejobo on ratio and diagram material. The method used in this research is a descriptive method with a qualitative approach. The subjects of this research were grade V students. Data was collected through mathematical reasoning tests, interviews and observations. The research results show that students' mathematical reasoning abilities in understanding the concept of ratios and diagrams are still at a medium level. Some students are able to apply the concept of ratios in various problem contexts, but most students have difficulty interpreting and making diagrams correctly. Things that influence this reasoning ability include a lack of understanding of basic concepts, a lack of practice on varied questions, and a lack of use of learning media that supports understanding the concepts of ratios and diagrams. Based on this research, it is recommended that teachers increase the use of interactive learning media and provide more varied practice questions to improve students' mathematical reasoning abilities.

Abstract

Background: Meskipun guru memiliki akses ke teknologi modern, guru sering kali tidak memanfaatkannya untuk membuat media karena keterbatasan kemampuan penguasaan teknologi, rendahnya pemahaman konsep desain, dan sibuknya jadwal mengajar. Guru-guru di SD 3 Klaling membutuhkan pelatihan tentang inovasi media presentasi melalui pemanfaatan artificial integelence salah satunya yaitu Gamma App. Tujuan dari pengabdian kepada masyarakat (PkM) ini yaitu untuk mentransfer pengetahuan kepada guru SD 3 Klaling melalui pemanfaatan Gamma App untuk membuat media presentasi. Metode: PkM ini dilaksanakan di SD 3 Klaling Kabupaten Kudus dengan peserta 11 orang guru. Metode PkM ini yaitu pelatihan interaktif dan advokasi (pendampingan). Tahapan pelaksanaan PkM yaitu: perencanaan, pelaksanaan, follow up, dan evaluasi. Sebelum dan setelah pelatihan diberikan tes untuk menganalisis peningkatan pengetahuan dan keterampilan guru. Hasil tes kemudian diolah untuk memperoleh nilai N-Gain dan kriteria peningkatannya. Hasil: Kegiatan PkM berdampak pada peningkatan pengetahuan dan keterampilan guru dalam pembuatan media presentasi dengan memanfaatkan Gamma App. Adapun skor N-Gain 68,52 dengan kriteria sedang. Kesimpulan: Kegiatan PKM ini mampu meningkatkan pengetahuan dan keterampilan guru SD 3 Klaling mengenai pemanfaatan Gamma App dalam penyusunan media presentasi. Gamma App dapat membantu guru dalam menyusun media presentasi yang dapat dimanfaatkan oleh guru sebagai media pembelajaran di kelas.

Abstract

Math majors must be excellent problem solvers because problem-solving is the foundation of teaching mathematics. Their problem-solving skills will help them create service initiatives as math teachers. This research investigated how well the APOS-based PBL model enhances students' skills in solving mathematical problems. This quasi-experimental design used a non-equivalent post-test-only control group, which is quantitative. Students at a university in Central Java, Indonesia, participated in the study. Tests of problem-solving skills were useful to collect the data. The results of the study showed that (1) students' problem-solving skills lead to learning completion (71); (2) students taught using a modified PBL model based on APOS theory have a different proportion of learning completeness than students taught using an average class using a direct learning model; (3) students' average problem-solving skills taught using the modified PBL model based on APOS theory are superior to those taught in the average class using a direct learning model; (4) increasing students' problem-solving skills taught using a modified PBL model based on APOS theory is preferable to improving students' skills taught using a direct learning model. This study offers insightful insights into the PBL model's implementation, incorporating APOS theory at every stage. These results suggest that to maximize students' problem-solving skills, consideration of the theory of thinking processes must be given when putting the learning model into practice      Keywords: APOS, mathematics, PBL, problem-solving skills.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1577-1592
