Abstract

Banyak siswa yang belum mampu menalar dan memahami masalah. Untuk menentukan solusi suatu masalah diperlukan penalaran dan pemahaman yang dapat membantu siswa menyelesaikan masalah kehidupan sehari-hari. Penelitian ini bertujuan untuk mendeskripsikan proses penalaran dan pemahaman matematis siswa SMP melalui masalah kehidupan sehari-hari. Penelitian ini termasuk dalam penelitian deskriptif kualitatif. Pemilihan subjek penelitian ini menggunakan purposive sampling dan subjek yang dipilih adalah 2 siswa yang memiliki kemampuan penalaran dengan pemahaman relasional dan instrumental. Instrumen penelitian ini adalah tes pemahaman Phytagoras, tes soal AKM Literasi Matematika dan pedoman wawancara. Hasil penelitian didapatkan bahwa S1 menyajikan data terlebih dahulu berdasarkan pemahaman dan petunjuk, kemudian membuat dugaan berdasarkan pemikirannya dengan menghubungkan pola dari ide-ide yang berkembang, lalu membuktikan kesahihan suatu argumen dengan memeriksa kembali jawaban dan memilih prosedur penyelesaian yang tepat dan dijabarkan secara rinci. Sedangkan S2 menyajikan data terlebih dahulu berdasarkan petunjuk, kemudian langsung membuat dugaan, pada pembuktian suatu argumen, S2 belum menjelaskan secara rinci prosedur penyelesaian yang digunakan dan hanya berpaku pada hafalan. Berdasarkan hasil penelitian, S1 termasuk dalam kemampuan penalaran dengan pemahaman relasional dan S2 termasuk dalam penalaran dengan pemahaman instrumental.

Abstract

Students often have difficulty in solving problems, this is due to lack of confidence and students' critical thinking skills are still low. Critical thinking skills are needed to make decisions in solving problems on problems. In order for students to make decisions, students must have confidence in practicing critical thinking skills. This study aims to describe students' critical thinking skills in solving story problems in junior high school students who have confidence. This research method is descriptive research with a qualitative approach, in the form of the results of the work of non-test students, written tests and in-depth interviews. This study included 2 subjects who had the ability to think critically with confidence. The results of this study show that students can meet all criteria such as (1) students are able to understand problems, write down problem information from known, namely Tini bought 2 pens and bought 1 writing book, while Aisyah bought more pens than Tini equivalent to the price of books, then what was asked was the price of 2 pens and 3 writing books, respectively, (2) students are able to analyze and create mathematical models, able to consider assumptions and determine the results of completion, namely solving mathematical models on the material of a system of two-variable linear equations (SPLDV). And (3) students are able to draw conclusions from the problem, namely being able to conclude from the results of the final solution correctly. So that students are able to understand, model and solve problems appropriately.

Abstract

Many students have difficulty solving the word geometry problem because it requires representation. This study analyzes the construction of representation of class XII students in solving three dimensional word problem. Research with descriptive methods to determine the representation construction that students use when given the task of solving three dimensional word problem. The results showed two constructs of representation, namely: pictorial representation and schematic representation. Students who construct pictorial representations produce correct answers while students who construct schematic representations produce correct answers in solving three-dimensional word problems.
