Abstract

This study aims to examine the application of mathematics learning using a multimedia-assisted analogy approach in developing mathematical representation. The sample used was grade 7 students of two classes, totaling 44 students. The research method used was a quasi-experimental design with randomized posttest only. Two classes were randomly selected as samples, namely class VII-1 as the experimental class and class VII-3 as the control class. The analysis was performed using the t-test at α = 5%, obtained t-count = 4.205> t-table = 2.018. The results indicate that the mathematical representation ability of students whose learning uses the analogy approach is significantly higher than students whose learning uses a conventional approach or in other words, the multimedia-assisted analogy approach can be used as alternative learning in developing student representation abilities especially in algebraic material.

Abstract

This study investigates high school students’ visual-spatial thinking ability in the context of transformation geometry using a descriptive quantitative design. A total of 241 students from public and Islamic high schools in Jakarta participated in the study, responding to a validated 40-item multiple-choice test assessing four key indicators: imagining, problem-solving, pattern seeking, and conceptualising. Results reveal that students generally performed at a medium level across all indicators, with the highest scores in imagining (M=62.97) and the lowest in conceptualising (M=47.05). These findings suggest that while students demonstrate some spatial reasoning capability, their conceptual understanding remains limited. The study highlights the importance of incorporating visualisation-focused strategies in geometry instruction to strengthen spatial reasoning and deeper comprehension of transformation concepts. Future research should explore the longitudinal impact of visual-spatial training and its role in developing higher-order geometrical thinking.

Abstract

The Ministry of Higher Education's Regulation No. 3, 2020, issued the MBKM curriculum as a foundation for learning development at the University. Since 2021, the mathematics education study program at UIN Syarif Hidayatullah Jakarta has been carrying out off-campus activities to support the MKBM curriculum. After 4 years of MBKM activities, the study program needs to survey to determine the effectiveness and usefulness of implementing the MBKM program. The purpose of this study is to describe the MBKM program and to find out the undergraduate students’ responses related to this. The research method is qualitative research with a survey method. The population was 288 undergraduate students in the mathematics study program, and the sample was 150. The instrument is a questionnaire to determine the effectiveness of the socialization of the MBKM program, the extent of understanding and perception of the MBKM curriculum, and its implementation. The results showed: 1) 27% of undergraduate students got information from the study program, 2) 78% of undergraduate students understood about the MBKM curriculum, and 3) more than 50% of undergraduate students agreed that outside-campus activities can improve teaching skills, mathematical content, and technology mastery. It was concluded that MBKM activities outside-campus positively impacted undergraduate students and need to continue. Recommendation: study programs need to conduct intense socialization about MBKM, and continue the outside-campus program, to train undergraduate students' pedagogical skills, content knowledge, and technology skills. Abstrak: Permen Ristek Dikti nomor 3 tahun 2020 menerbitkan kurikulum MBKM sebagai landasan pengembangan pembelajaran di Perguruan Tinggi. Program studi pendidikan matematika UIN Syarif Hidayatullah Jakarta telah melaksanakan kegiatan di luar kampus sejak tahun 2021 untuk mendukung kurikulum MKBM. Setelah 4 tahun kegiatan MBKM berlangsung, program studi perlu melakukan survei untuk mengetahui efektifitas dan kebermanfaatan program MBKM. Tujuan dari penelitian ini yaitu mendeskripsikan kegiatan pada program MBKM dan mengetahui respon mahasiswa terkait dengan kegiatan MBKM yang telah dilaksanakan. Metode penelitian yang digunakan adalah penelitian kualitatif dengan metode survei. Populasinya sebanyak 288 mahasiswa aktif pada Program Studi Pendidikan Matematika,  sampel penelitian sebanyak 150. Instrumen yang digunakan dalam penelitian ini adalah angket. Angket digunakan untuk mengetahui efektivitas sosialisasi program MBKM, tingkat pemahaman mahasiswa terhadap kurikulum MBKM dan persepsi  terhadap implementasinya. Hasil penelitian menunjukkan bahwa 1) 27% mahasiswa mendapatkan informasi  tentang  kurikulum MBKM dari program studi, 2) 78% mahasiswa memahami tentang kurikulum MBKM, dan 3) lebih dari 50% mahasiswa memahami menyatakan setuju bahwa kegiatan di luar kampus dapat meningkatkan keterampilan mengajar, kemampuan konten matematika, dan meningkatkan penguasaan teknologi. Berdasarkan hasil penelitian disimpulkan  bahwa kegiatan MBKM di luar kampus memberikan dampak positif bagi mahasiswa dan tetap dilaksanakan. Rekomendasi: program studi perlu melakukan sosialisasi tentang MBKM secara intens, dan tetap melanjutkan program MBKM di luar kampus, untuk melatih kemampuan pedagogis, pengetahuan konten matematika, dan kemampuan memanfaatkan teknologi mahasiswa.

Abstract

Bruner's theory is particularly notable for its application in mathematics, as it outlines three steps in the teaching process: enactive, iconic, and symbolic. This research aims to implement Bruner's theory in teaching Angles on circles to improve problem-solving skills. The research method is a quasi-experiment with a posttest-only control group design. Using cluster random sampling, two classes from one of the junior high schools in Jakarta were selected as samples: the first as an experimental class of 30 students, who learned using Bruner's theory, and the second as a control class of 31 students, who learned with a conventional approach. The instrument is a mathematical problem-solving test in the form of an essay test of four questions. The questions are given at the end of the lesson, and the instruments have been validated through content validity and empirical validity. The results show that, through t-test analyses, it was found that students’ problem-solving skills, who learn using Bruner's theory, are higher than those of students who learn using conventional methods. It demonstrates that teaching using Bruner’s theory is effective in improving students’ problem-solving skills, particularly in the Area of Angles on circles.

Abstract

AbstractEthnomathematics is defined as the integration between a specific culture and mathematics. This research aims to develop teaching materials as a learning module on geometry building space integrated with Betawi culture. The research method is R&D with the Plomp model, which consists of five phases: preliminary investigation; design; construction/ realization; test, evaluation, and revision; also implementation. The subjects in this study consisted of three Lecturers of Mathematics Education at UIN Syarif Hidayatullah Jakarta, one junior high school teacher, and two high school teachers in the North Jakarta area. In addition, in this study, four junior high school students and four high school students were also involved as respondents in assessing the readability of the modules made.The results of assessments from experts show that the modules made are very feasible. The results of the students' responses to the learning module are included in the perfect category. So, it was concluded that the module could be used as additional material for teachers in teaching the geometry of flat buildings and building spaces using Betawi culture. Abstrak Etnomatematika merupakan integrasi antara budaya tertentu dengan matematika.
