Abstract

The ability to solve contextual mathematical problems is a crucial skill that students need to possess. However, students often encounter difficulties in solving problems presented in real-life contexts. Understanding students' thought processes in solving contextual problems can provide valuable insights for teachers to design more effective learning strategies. This research aims to explore and gain a deep understanding of students' thinking processes when solving contextual mathematical problems, focusing on how students comprehend the problems, the strategies they employ in problem-solving, and the difficulties they encounter during the process. This study will employ a qualitative approach using a case study method, where data will be collected through observations, in-depth interviews, and analysis of students' work. The collected data will be thematically analyzed to identify patterns, strategies, and difficulties experienced by students, with data analysis conducted progressively and iteratively to ensure the depth and validity of findings. The research findings are expected to provide valuable insights into students' thinking processes in solving contextual mathematical problems, which can be utilized by teachers to design more effective learning strategies, assist students in developing problem-solving skills, and enhance students' ability to apply mathematics in everyday life.

Abstract

Di era globalisasi yang terus berkembang pesat, kemampuan berpikir logis, analitis, dan kritis menjadi semakin penting untuk dimiliki setiap individu. Pendidikan matematika memiliki peran sentral dalam mengasah kemampuan-kemampuan tersebut, sehingga generasi muda dapat dipersiapkan untuk menghadapi tantangan dan memanfaatkan peluang di masa depan dengan lebih baik. Mengingat perannya yang krusial, penelitian di bidang pendidikan matematika menjadi sangat penting untuk terus dilakukan guna meningkatkan kualitas proses pembelajaran dan hasil belajar siswa. Penelitian ini melakukan kajian sistematis terhadap 123 tesis S2 Pendidikan Matematika di Universitas Negeri Medan periode 2020-2023 dengan tujuan mengidentifikasi tren penelitian, mencakup analisis topik utama yang diteliti, perkembangan fokus dari tahun ke tahun, serta metode penelitian yang digunakan. Hasil penelitian mengungkapkan topik terbanyak adalah pengembangan model/metode pembelajaran matematika, diikuti analisis kemampuan/keterampilan siswa dalam matematika, dan pengembangan media/teknologi pembelajaran, dengan metode penelitian yang dominan adalah Research and Development (R&D) serta Eksperimentan Research. Teridentifikasi pula pergeseran fokus tahunan seperti peningkatan penelitian pengembangan model/metode pembelajaran pada 2022-2023, mencerminkan komitmen untuk berinovasi, memahami kemampuan siswa secara mendalam, serta mengintegrasikan teknologi di tengah perkembangan zaman dan tuntutan pasar kerja.

Abstract

This study investigated the effectiveness of Problem Based Learning (PBL) compared to the Traditional Learning Model in mathematics education, focusing on two key aspects: students' mathematical critical thinking skills and learning independence. The research examined whether PBL yielded better results than traditional methods in enhancing these capabilities, while also analyzing potential interactions between learning approaches and students' initial mathematical abilities. The study was conducted with a sample of 60 tenth-grade students from MAN 1 Medan, drawn from classes X-9 and X-6, who were divided into experimental and control groups. Using mathematical critical thinking skills assessments and a learning independence scale, data were analyzed through two-way ANOVA. The results demonstrated that the PBL model was significantly more effective than the Traditional Learning Model in improving both students' mathematical critical thinking skills and learning independence. However, no significant interactions were found between learning approaches and students' initial mathematical abilities in either the development of critical thinking skills or learning independence. These findings strongly suggest that Problem Based Learning should be considered as an effective instructional strategy for educators seeking to enhance their students' mathematical critical thinking skills and foster greater learning independence in the classroom.

Abstract

The objectives of this research were to determine: (1) the effect of the Problem Based Learning learning model is better than the Ordinary Learning Model on improving students' critical mathematical thinking skills; (2) the interaction between learning and students' initial mathematical abilities on improving students' critical mathematical thinking skills; (3) the effect of the Problem Based Learning learning model is better than the Ordinary Learning Model on improving students' learning independence; (4) the interaction between learning and students' initial mathematical abilities on improving students' learning independence. The population in this study consisted of all tenth-grade students at MAN 1 Medan, and the sample comprised 60 students from classes X-9 and X-6, divided into experimental and control groups. The instruments used included a mathematical critical thinking skills test and a learning independence scale. Data were analyzed using two-way ANOVA. Based on the analysis, the following results were obtained: (1) The Problem Based Learning learning model has a better effect than the ordinary learning model in improving students' critical mathematical thinking skills; (2) there is no interaction between learning and students' initial mathematical abilities on improving students' critical mathematical thinking skills; (3) The Problem Based Learning learning model has a better influence than the ordinary learning model in increasing students' learning independence; (4) there is no interaction between learning and students' initial mathematical abilities towards increasing students' learning independence. Based on the results of this study, it is suggested that learning with problem based learning be used as an alternative for teachers to increase students' critical mathematical thinking skills and learning independence.
