Abstract

Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh model pembelajaran kooperatif tipe Teams Games Tournament (TGT) pada pembelajaran jarak jauh terhadap kemampuan penalaran matematis siswa SMP Negeri 7 Jakarta dan untuk mengetahui besar pengaruh signifikan dari penerapan model pembelajaran kooperatif tipe Teams Games Tournament (TGT) terhadap kemampuan penalaran matematis siswa di SMP Negeri 7 Jakarta. Metode penelitian yang digunakan adalah metode eksperimen semu. Instrumen penelitian yang digunakan adalah instrumen tes kemampuan penalaran matematis berupa 5 soal uraian yang telah dinyatakan valid dan reliabel. Populasi target penelitian adalah seluruh peserta didik SMP Negeri 7 Jakarta. Populasi terjangkau penelitian adalah siswa kelas VII SMP Negeri 7 Jakarta. Teknik pengambilan sampel menggunakan teknik simple random sampling untuk menentukan kelas eksperimen (model pembelajaran kooperatif tipe Teams Games Tournament) dan kelas kontrol (model pembelajaran konvensional). Berdasarkan uji prasyarat analisis data setelah perlakuan, data pada kedua kelas berdistribusi normal dan memiliki varians yang tidak homogen. Pengujian hipotesis statistik uji-t' pada taraf signifikansi a = 0,05, diperoleh thitung = 3,041 lebih tinggi dari nilai kritis = 1,686, maka H0 ditolak dan diperoleh kesimpulan bahwa rata-rata skor tes kemampuan penalaran matematis siswa kelas eksperimen lebih tinggi dari kelas kontrol. Besar pengaruh pada perhitungan Cohen’s Effect Size (ES), diperoleh ES = 0,684 dengan percent of Non Overlap sebesar 38,2% yang dikategorikan medium. Hal ini menunjukkan bahwa terdapat pengaruh signifikan dari penerapan model pembelajaran kooperatif tipe Teams Games Tournament (TGT) pada pembelajaran jarak jauh terhadap kemampuan penalaran matematis siswa SMP Negeri 7 Jakarta.

Abstract

This research aims to develop media of comic mathematics with realistic mathematics education Indonesia approach on social arithmetics for seventh-grade junior high school. This developmental research develops a comic of mathematics using the development model from Borg and Gall with five stages. The five stages are (1) Need analysis for teacher dan students; (2) planning and developing the product; (3) the validation from material and language experts and media experts; (4) small group test; (5) significant group test. The data were analyzed using qualitative and quantitative analysis techniques. The feasibility of the product was assessed by processing data from a questionnaire based on the validation results of media experts, validation of material and language experts, teachers, and students not only in a small group test but also in a significant group test. The result of this research is a comic of mathematics with a realistic mathematics education approach to social arithmetics. Based on this research, the percentage of the product feasibility was 86,40%, categorized as very feasible. Based on data, it can be implied that the media of comic mathematics with a realistic mathematics education approach to social arithmetics is feasible to use.

Abstract

This study aims to describe the effectiveness of a fraction textbook for slow‐learner students in elementary schools. The research design employed was a one-group pretest–posttest design. The sample consisted of slow‐learner students, and the learning material used in this study was fractions. Research data were obtained through pretests and posttests, and the pretest–posttest analysis was conducted using the N-Gain calculation. The results show that the learning outcomes of slow‐learner students (N-Gain) fall into the medium category. Based on these findings, the fraction textbook is effective in improving slow‐learner students’ conceptual understanding and implies that similar textbooks may serve as alternative learning resources to support fraction learning for slow‐learner students.
