Abstract

This research is motivated by the limited use of mathematics teaching materials in schools. This research aims to develop teaching materials based on Case-Based Learning on Junior High School statistics in Grade VIII. This teaching material has systematically arranged using Case-Based Learning steps. The Teaching Materials were developed to consist of 3 learning activities: 1)  Data Analysis, 2) Mean, Median, Mode, and 3) Range and Quartile. The research method used is the research and development method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. Teaching materials go through the validation and limited trial stage on five aspects: content feasibility, language, presentation, graphics, and Case-Based Learning. The results showed that the teaching materials developed have Very Valid criteria based on the Validator's assessment. It is getting a V Aiken coefficient of 0.8890, while the students' responses resulted in 82.33% on very feasible criteria. So we can conclude that the Case-Based Learning teaching materials on Statistics material are suitable to be used as a support for learning mathematics in schools.

Abstract

Pengabdian kepada masyarakat merupakan salah satu tridharma perguruan tinggi. Prodi pendidikan matematika UIN Syarif Hidayatullah Jakarta melak­sanakan pengabdian Tahun 2022 di Desa Pulosari Kabupaten Pandeglang Banten dengan tujuan: (1) memberikan pendampingan kepada guru-guru MI tentang pendekatan pembelajaran matematika yang mendukung pada kurikulum merdeka belajar (2) memberikan pelatihan tentang literasi matematika bagi guru MI, (3) memberikan pendampingan kepada siswa dalam belajar matematika yang mudah dan menyenangkan. Metode yang digunakan yaitu pendekatan partisipatif, dimana dosen dan mahasiswa ter­libat langsung dalam memberikan layanan masyarakat. Pengabdian dilaksa­nakan pada bulan Agustus tahun 2022 dengan melibatkan 60 mahasiswa, 9 dosen, 57 guru MI yang berasal dari 19 MI dan siswa-siswi sebanyak 22 kelas. Hasil pengabdian menunjukkan bahwa 1) Mahasiswa memiliki pengalaman langsung dalam mengimplementasikan strategi pembelajaran di kelas; 2) Siswa merasa terbantu dalam belajar matematika, mereka lebih interaktif belajar, siswa juga merasakan bahwa matematika itu tidak sulit; 3) Sebagian besar guru MI di kecamatan Pulosari belum memahami tentang implementasi pendekatan problem based learning dan project based learning; 4) Sebagian besar guru MI di kecamatan Pulosari masih mengalami kesulitan dalam membuat soal HOTS, 5) sebagian guru tidak dapat menyelesaikan soal literasi; dan 5) guru memberikan respon positif terhadap pelaksanaan kegiatan pengabdian.

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

Penelitian ini bertujuan mengembangkan e-modul interaktif pada materi garis dan sudut untuk siswa SMP, menguji kelayakan produk, mendeskripsikan respon siswa, dan melihat capaian hasil belajar setelah penggunaan produk. Pengembangan dilakukan karena materi garis dan sudut memiliki karakter visual-spasial yang sering dianggap abstrak, sementara bahan ajar digital yang tersedia belum sepenuhnya memberi pengalaman belajar interaktif dan mandiri. Penelitian menggunakan metode Research and Development dengan model ADDIE yang mencakup analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek uji lapangan adalah 34 siswa kelas VII-A pada salah satu SMP negeri di Kabupaten Bogor. Instrumen penelitian meliputi lembar validasi ahli, angket praktisi, angket respon siswa, dan tes hasil belajar. Produk dikembangkan menggunakan Canva, Lumi Education, dan Heyzine dengan tema Misi Detektif Geometri. Hasil penelitian menunjukkan bahwa validasi ahli memperoleh rata-rata 94,05% dengan kategori sangat layak, uji praktisi memperoleh 91,67% dengan kategori sangat layak, respon siswa uji terbatas memperoleh 87,85% dan respon uji lapangan memperoleh 89,52% dengan kategori sangat baik. Nilai rata-rata post-test siswa adalah 83,75 dengan skewness -0,572. Dengan demikian, e-modul interaktif yang dikembangkan layak digunakan sebagai media pembelajaran matematika pada materi garis dan sudut.

Abstract

Today's technology is increasingly dominating all aspects of life, including the use of technology in education, one of which is education at RA level. This research is integrated with community service activities which aim to train RA teachers to 1) utilize interactive projector-based ICT learning media in learning, 2) develop interactive projector-based ICT media for early childhood, 3) provide an overview of RA student activities in learning using interactive projector-based ICT media. Method The R&D method is used in developing interactive projector-based ICT applications and media to improve RA students' learning activities in the classroom. Interactive projector based ICT media trials were conducted in two RAs, namely RA Al-Hidayah students and RA Al-Husaeni students. Pandeglang district, Banten Province. The results showed that 1) arranged interactive learning applications for early childhood using interactive projector-based ICT media, 2) The thematic learning process in RA using interactive projector-based ICT media was very enjoyable, this was shown by the enthusiasm of students in participating in lessons and there is also an increase in the learning activities of RA students in Pandeglang Regency. 3) The teacher gives a positive response to the use of interactive projectors in thematic learning in class RA

Abstract

Abstract Junior high school students’ mathematical Higher Order Thinking Skills (HOTS) in Indonesia remain relatively low, while studies applying machine learning to identify the factors influencing HOTS are still limited. This study aims to develop a predictive model of students’ mathematical HOTS, identify its key predictors, and determine the best-performing algorithm. A descriptive quantitative approach was employed with 391 seventh- and eighth-grade students from a state Islamic junior high school (MTs) in South Jakarta. Data were collected through a questionnaire measuring internal and external learning factors and a HOTS-based essay test, then analyzed using Chi-Square feature selection and seven supervised machine learning algorithms in Orange Data Mining. The results identified physiological condition, fatigue, and intelligence as the strongest predictors of HOTS, whereas school environment and learning motivation contributed minimally. Among the algorithms, Naïve Bayes achieved the most consistent predictive performance. These findings provide data-driven evidence for designing instructional strategies that support students’ mathematical HOTS.  Abstrak Kemampuan Higher Order Thinking Skills (HOTS) matematis siswa SMP di Indonesia masih relatif rendah, sementara penelitian yang memanfaatkan machine learning untuk mengidentifikasi faktor-faktor yang memengaruhinya masih terbatas. Penelitian ini bertujuan mengembangkan model prediksi HOTS matematis siswa, mengidentifikasi faktor-faktor dominan yang memengaruhinya, serta menentukan algoritma dengan kinerja terbaik. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 391 siswa kelas VII dan VIII di salah satu MTs Negeri di Jakarta Selatan. Data dikumpulkan melalui angket faktor internal dan eksternal serta tes uraian berbasis HOTS, kemudian dianalisis menggunakan seleksi fitur Chi-Square dan tujuh algoritma supervised machine learning pada Orange Data Mining. Hasil menunjukkan bahwa kondisi fisiologis, kelelahan, dan inteligensi merupakan prediktor utama HOTS matematis, sedangkan lingkungan sekolah dan motivasi belajar memberikan kontribusi yang minimal. Di antara seluruh algoritma, Naïve Bayes menunjukkan kinerja prediksi yang paling konsisten. Temuan ini memberikan dasar berbasis data untuk merancang strategi pembelajaran yang mendukung pengembangan HOTS matematis siswa.
