Abstract

Schools play a critical role in enabling students to discover, develop, and express their creative potential. However, instructional practices that explicitly promote students’ creative thinking skills in mathematics learning remain limited. Therefore, this study aims to examine and describe the creative thinking processes of junior high school students in solving mathematical reasoning problems. This study employed a qualitative case study design involving 35 eighth-grade students. A mathematical reasoning test was administered to identify students’ levels of creative thinking. Based on the results, four students representing different categories of creative thinking (imitative, routine, creative, and very creative) were purposively selected as research subjects. Data were collected through students’ written work, in-depth interviews, and document analysis. The findings indicate that each category demonstrates distinctive characteristics in terms of problem-solving strategies, flexibility of ideas, and originality in constructing solutions. Students in the higher creative categories tended to generate multiple strategies and more original solution processes. These findings emphasize the importance of designing mathematics learning activities that encourage exploration of diverse strategies, idea generation, and reflective thinking.

Abstract

Mathematical argumentation is important for developing students’ reasoning abilities. This study aims to analyze junior high school students’ written and oral argumentation abilities when solving reasoning tasks. This research employed a descriptive qualitative approach, involving 31 ninth-grade students from SMP Negeri 7 Muaro Jambi. The study was conducted in the odd semester of the 2024/2025 academic year. The research instruments consisted of a mathematical reasoning test, interview protocols, and documentation. The mathematical reasoning test included three questions. The results of the tests and interviews were analyzed using the main components of Toulmin’s argumentation model, which consist of claims, data, warrants, backing, qualifiers, and rebuttals. Based on the test and interview results, students’ argumentation abilities were categorized into five levels, from Level 1 to Level 5. The findings show that 31 students (100%) reached Level 1, 15 (48.38%) reached Level 2, and 9 (29.03%) reached Level 3. No students reached Level 4 or Level 5. These findings indicate that students can construct claims, data, and warrants when solving mathematical reasoning tasks. However, students still need to be trained to develop backing, qualifiers, and rebuttals in order to complete the argumentation process appropriately in both written and oral forms.

Abstract

Kemampuan representasi matematis berperan penting dalam proses pemecahan masalah, khususnya pada soal open-ended yang menuntut fleksibilitas berpikir siswa. Penelitian ini bertujuan untuk menganalisis kemampuan representasi matematis siswa dalam menyelesaikan masalah open-ended pada materi Teorema Pythagoras. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Subjek penelitian dipilih berdasarkan kategori kemampuan representasi matematis tinggi, sedang, dan rendah. Data dikumpulkan melalui tes tertulis berbentuk soal open-ended serta wawancara semi-terstruktur. Hasil penelitian menunjukkan bahwa terdapat perbedaan karakteristik representasi matematis pada setiap kategori kemampuan. Siswa dengan kemampuan tinggi mampu mengintegrasikan representasi verbal, visual, dan simbolik secara tepat dan fleksibel. Siswa kategori sedang mampu menggunakan representasi verbal dengan cukup baik, namun masih mengalami kesulitan dalam konsistensi representasi visual dan simbolik. Sementara itu, siswa kategori rendah belum mampu mengonstruksi representasi matematis secara sistematis dan mengalami kesulitan dalam mentransformasikan permasalahan ke dalam model matematika. Temuan ini menunjukkan bahwa tingkat kemampuan dasar siswa memengaruhi kualitas dan kelengkapan representasi matematis yang digunakan dalam pemecahan masalah open-ended pada materi Teorema Pythagoras.

Abstract

Kemampuan argumentasi matematis merupakan salah satu kompetensi penting yang harus dimiliki siswa dalam pembelajaran matematika, khususnya dalam menyelesaikan soal open-ended yang menuntut penalaran, justifikasi, dan komunikasi matematis. Namun, pada kenyataannya, banyak siswa masih mengalami kesulitan dalam menyusun argumentasi matematis yang logis, sistematis, dan lengkap, terutama pada materi bilangan berpangkat. Kondisi ini menunjukkan pentingnya dilakukan analisis mendalam terhadap kemampuan argumentasi matematis siswa. Penelitian ini bertujuan untuk menganalisis kemampuan argumentasi matematis siswa dalam menyelesaikan soal open-ended pada materi bilangan berpangkat. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan melibatkan siswa kelas VIII SMP sebagai subjek penelitian. Data dikumpulkan melalui tes soal open-ended dan wawancara semi terstruktur, kemudian dianalisis menggunakan kerangka argumentasi Toulmin yang meliputi claim, data, warrant, backing, qualifier, dan rebuttal. Hasil penelitian menunjukkan bahwa kemampuan argumentasi matematis siswa berada pada kategori yang bervariasi, dimana sebagian siswa mampu menyampaikan claim dan data dengan baik, namun masih mengalami kesulitan dalam menyusun warrant, backing, qualifier, dan rebuttal secara lengkap. Kesulitan tersebut disebabkan oleh kurangnya pemahaman konsep dan kurangnya pengalaman dalam menyelesaikan soal open-ended. Oleh karena itu, diperlukan strategi pembelajaran yang dapat mendukung pengembangan kemampuan argumentasi matematis siswa secara optimal.
