Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis matematis siswa berdasarkan tingkat rasa ingin tahu. Fokus penelitian diarahkan pada ketercapaian indikator berpikir kritis matematis, yaitu Interpretation, Analysis, Evaluation, dan Inference, dengan memperhatikan tingkat rasa ingin tahu siswa kategori tinggi, sedang, dan rendah. Metode penelitian yang digunakan adalah kualitatif deskriptif dengan pendekatan eksplorasi. Subjek penelitian dipilih secara purposive sampling dari siswa kelas IX SMP Negeri 2 Tasikmalaya Tahun Ajaran 2025/2026. Instrumen yang digunakan meliputi tes kemampuan berpikir kritis matematis, angket rasa ingin tahu, dan wawancara tak berstruktur. Analisis data dilakukan melalui reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa subjek dengan rasa ingin tahu kategori tinggi mampu memenuhi seluruh indikator berpikir kritis matematis serta menunjukkan antusiasme dalam menyelesaikan soal. Subjek dengan rasa ingin tahu kategori sedang juga mampu memenuhi seluruh indikator, namun masih kurang percaya diri dalam memberikan jawaban. Sementara itu, subjek dengan rasa ingin tahu kategori rendah hanya mampu memenuhi indikator Interpretation dan Analysis. Temuan ini mengindikasikan bahwa tingkat rasa ingin tahu memiliki peran penting terhadap ketercapaian kemampuan berpikir kritis matematis. Penelitian ini memberikan gambaran bahwa pengembangan rasa ingin tahu siswa dapat dijadikan salah satu alternatif dalam upaya meningkatkan kemampuan berpikir kritis matematis.

Abstract

This study aimed to develop Minimum Competency Assessment (MCA)-based geometry instructional materials to support junior high school students’ mathematical literacy, particularly in the formulate–employ–interpret process. The research employed a Research and Development (RD) method using the ADDIE model, which consists of the stages of analysis, design, development, implementation, and evaluation. The analysis stage revealed learning gaps, including the dominance of procedural approaches, limited use of visual and contextual media, and students’ difficulties in interpreting contextual geometry problems. The instructional materials were developed with contextual introductions, concept visualizations, AKM-based tasks, reflection activities, and geometric nets. Product validity was assessed by a content expert and a media expert, covering content and objective quality, instructional quality, and technical quality, with an average score of 74.3% (valid category). Practicality testing involving 25 eighth-grade students showed percentages ranging from 77% to 79%, indicating that the instructional materials are feasible and practical for classroom use. Further studies are recommended to examine effectiveness through experimental designs and to expand the development of interactive media. Copyright © 2021University of Siliwangi. All rights reserved.

Abstract

This study aims to develop a mathematics learning device based on Case Based Learning (CBL) integrated with digital comics media for the topic of Systems of Linear Equations in Two Variables (SPLDV) for junior high school students. The method used is Research and Development (RD) with the ADDIE model, encompassing analysis, design, development, implementation, and evaluation stages. Validation involved subject matter experts, media experts, and limited trials with students. The results show that the developed learning device is highly feasible, with an average validation score of 89.2%. The use of digital comics media based on CBL significantly increases students' motivation and conceptual understanding of mathematics, as evidenced by a 24.2% increase in the average SPLDV conceptual understanding score. In conclusion, the integration of the CBL model and digital comics is effective in supporting contextual, innovative, and adaptive mathematics learning in the digital eraKeywords:    Case Based Learning; digital comics; conceptual understanding; mathematics education; instructional innovation.
