Abstract

Mathematics education in the 21st century requires the integration of technology and interdisciplinary approaches to meet students’ diverse learning needs. However, conventional teaching materials often fail to engage students actively or connect mathematical concepts to real-world contexts. This research aims to develop interactive teaching materials based on the Science, Technology, Religion, Engineering, Arts, and Mathematics (STREAM) framework for the topic of ratio by utilizing the Lumio platform to enhance the learning experience. This research employed the ADDIE development model consisting of Analyze, Design, Develop, Implement, and Evaluate stages. The study involved 3 expert validators, 1 mathematics teacher, and 42 Grade VII students, including 10 students in the small-scale trial and 32 students in the large-scale trial. The instruments used in this study included expert validation sheets, practicality questionnaires, and systematic thinking skill tests. At the same time, the data were analyzed using percentage techniques based on validity, practicality, and effectiveness criteria. The results showed that the developed teaching materials achieved validity scores of 85%, 84%, and 92%, categorized as “very valid.” The practicality results reached 82% from students and 86% from the teacher in the small-scale trial, while the large-scale trial obtained a score of 80%, categorized as “practical” to “very practical.” Furthermore, the effectiveness test showed an increase in student learning outcomes, resulting in an effectiveness percentage of 73%, categorized as “effective.” These findings indicate that the STREAM-based teaching materials assisted by Lumio are valid, practical, and effective for teaching ratio topics.

Abstract

This study aims to analyze the relationship between students' self-confidence levels and their mathematical understanding of rows and series. The research was conducted using descriptive qualitative method on 30 grade X students in one of the high schools in Bandung Regency. The research data were collected through a mathematical comprehension ability test consisting of five essay questions and a self-confidence questionnaire with four main indicators: confidence in one’s own abilities, acting independently, self-respect, and enthusiasm in discussions. The results showed that students with low self-confidence had an average mathematical understanding score of 18.89, while students with moderate self-confidence had an average of 52.2, and students with high self-confidence had the highest average of 95. This shows that the higher students' self-confidence, the better their ability to understand and solve mathematical problems. This study concludes that self-confidence is one of the important aspects that support students' mathematical understanding ability.

Abstract

The purpose of this study is to evaluate the mathematical critical thinking ability of eleventh-grade students from an independence perspective; comparative and inverse value materials are used to assess this ability. This exploratory study uses a qualitative descriptive approach. This study involved 30 eleventh-grade students at a high school in Bandung City. With a focus on three subjects: high, medium, and low self-efficacy. The instruments used in this study are questionnaires on Mathematical Critical Thinking Ability (KBKM), interviews, and self-efficacy questionnaires. Check the data with time triangulation. The results of the study show that: (1) students with a high level of self-efficacy have excellent KBKM; (2) students with a medium level of self-efficacy have moderate KBKM; and (3) students with a low level of self-efficacy have poor KBKM. As a result, teachers must pay attention to the components of the student independence scale when training students' critical thinking skills in mathematics

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas model pembelajaran Gallery Walk dalam meningkatkan kemampuan komunikasi matematis dan self confidence siswa kelas VIII SMPN 2 Cileunyi. Metode penelitian yang digunakan adalah quasi-eksperimen dengan desain non-equivalent control group, melibatkan dua kelas yang terdiri atas 50 siswa, yaitu kelas eksperimen yang memperoleh pembelajaran Gallery Walk dan kelas kontrol yang memperoleh pembelajaran konvensional. Instrumen penelitian meliputi tes kemampuan komunikasi matematis (pretest-posttest), angket self confidence, dan lembar observasi keterlaksanaan pembelajaran. Hasil penelitian menunjukkan bahwa kemampuan komunikasi matematis siswa pada kelas eksperimen mengalami peningkatan dengan rata-rata  sebesar 0,511 (kategori sedang), lebih tinggi dibandingkan kelas kontrol sebesar 0,335. Selain itu, self confidence siswa juga mengalami peningkatan berdasarkan hasil angket. Hasil uji independent sample t-test menunjukkan adanya perbedaan yang signifikan antara kedua kelompok ( = 0,009 < 0,05), sehingga model pembelajaran Gallery Walk efektif dalam meningkatkan kemampuan komunikasi matematis dan self confidence siswa. Temuan ini menunjukkan bahwa model pembelajaran Gallery Walk dapat menjadi alternatif pembelajaran yang interaktif dan kolaboratif untuk meningkatkan kemampuan komunikasi matematis serta aspek afektif siswa.

Abstract

Penelitian ini bertujuan untuk mengkaji peningkatan kemampuan pemahaman konsep matematis peserta didik yang menggunakan game edukasi Math Tower Race berbasis Roblox dibandingkan dengan peserta didik yang menggunakan pembelajaran konvensional. Metode yang digunakan adalah metode kuasi eksperimen dengan desain nonequivalent control group design. Subjek penelitian adalah 60 peserta didik kelas VII di salah satu SMP Provinsi Jawa Barat, yang terbagi ke dalam kelas eksperimen (30 peserta didik) menggunakan Math Tower Race dengan model Game Based Learning, dan kelas kontrol (30 peserta didik) menggunakan pembelajaran konvensional. Pengumpulan data dilakukan melalui pretest dan posttest kemampuan pemahaman konsep matematis pada materi persamaan linear satu variabel. Analisis data menggunakan rumus dan uji Independent Sample t-Test. Hasil penelitian menunjukkan bahwa rata-rata kelas eksperimen sebesar 0,75 (kategori tinggi), lebih tinggi dibandingkan kelas kontrol dengan rata-rata sebesar 0,66 (kategori tinggi). Berdasarkan uji Independent Sample t-Test diperoleh nilai signifikansi dua arah sebesar 0,007 < 0,05, sehingga H₀ ditolak. Hal ini membuktikan bahwa terdapat perbedaan peningkatan kemampuan pemahaman konsep matematis yang signifikan antara peserta didik yang menggunakan game edukasi Math Tower Race dan peserta didik yang menggunakan pembelajaran konvensional.
