Abstract

The purpose of this research was to know the thinking processes of climber, camper, and quitter high school students in solving mathematical problems. This research used a qualitative descriptive method. Subjects were determined by purposive sampling. The technique of collecting data was done by task-based interviews. Based on the results of data analysis it can be concluded that: (1) the profiles of climber’s thinking processes are: (a) assimilation and abstraction  in understanding problems, (b) assimilation, accommodation, and abstraction in planning problem solving (c) assimilation, accommodation, and abstraction in implementing the plan of problem solving, and  (d) accommodation in checking the solution; (2) the profiles of camper’s thinking processes are: (a) assimilation in understanding mathematical problems, (b) assimilation, accommodation, and abstraction in planning problem solving, (c) abstraction in implementing the plan of problem solving, and (d) assimilation in checking the solution; (3) the profiles of quitter’s thinking processes are: (a) assimilation and abstraction in understanding problems, (b) assimilation, accommodation, and abstraction in planning problem solving, (c) assimilation, accommodation, and abstraction in implementing the plan of problem solving, and (d) assimilation in checking the solution.

Abstract

Berpikir kritis merupakan salah satu keterampilan utama yang dibutuhkan dalam berkarir di era digital. Meskipun berpikir kritis telah dipelajari, pemikiran kritis siswa belum begitu ditekankan dalam matematika sekolah. Namun, penting untuk memberikan kehidupan siswa di masyarakat di masa depan, terutama ketika mereka menghadapi situasi yang tidak dikenal. Penelitian ini bertujuan untuk mendukung penalaran matematis siswa pada materi barisan dan deret dengan menggunakan pembelajaran berbasis masalah. Langkah-langkah pembelajaran mengintegrasikan masalah kontekstual pada lembar kerja di setiap episode. Penelitian ini merupakan penelitian tindakan kelas. Pengumpulan data menggunakan dokumentasi dan tes tertulis untuk menggali kemampuan berpikir kritis siswa. Analisis data paket pembelajaran dilakukan secara kualitatif, sedangkan kemampuan berpikir kritis siswa diolah dengan analisis deskriptif kuantitatif. Penelitian ini menyajikan deskripsi episode pembelajaran yang difokuskan untuk mengatasi pemikiran kritis siswa tentang masalah barisan dan deret. Analisis data menekankan pada lembar kerja masalah kontekstual pada pembelajaran berbasis masalah. Selain itu, kemampuan berpikir kritis siswa dijelaskan dengan metode kualitatif. Berpikir kritis siswa ditingkatkan dengan mendapatkan pembelajaran berbasis masalah dengan LKS kontekstual, meskipun keterampilan pada indikator penilaian dan inferensi belum optimal.
