Abstract

Penelitian ini dimaksudkan untuk mengidentifikasi hambatan belajar yang dihadapi oleh siswa pada materi bangun ruang sisi datar. Data dipenelitian ini diperoleh melalui tes dan wawancara. Metode penelitian yang digunakan adalah metode kualitatif dengan pendekatan studi kasus. Penelitian ini melibatkan 28 siswa kelas VIII di salah satu SMPN di Kabupaten Deli Serdang, Sumatera Utara. Hambatan belajar yang ditemukan dalam penelitian ini bersifat ontogenik dan epistemologis. Hambatan ontogenik merupakan hambatan belajar yang muncul terkait dengan perkembangan kemampuan berpikir siswa. Hambatan belajar ini bisa diakibatkan oleh ketidaksesuaian pembelajaran atau pengetahuan yang hendak dikonstruksikan oleh siswa dengan kemampuan berpikirnya. Sedangkan hambatan epistemologis merupakan hambatan yang terjadi akibat keterbatasan pemahaman konsep yang dimiliki oleh siswa. Siswa hanya memahami konsep secara parsial, sehingga siswa mengalami kesulitan saat dihadapkan pada konteks yang berbeda.

Abstract

This research aims to identify the learning obstacles faced by students in the topic of quadratic equations. The data for this study were obtained through tests and interviews. A qualitative research method with a hermeneutic phenomenology design was employed. The study involved 30 ninth-grade students from a junior high school in Banjar Regency, South Kalimantan. Several learning obstacles were experienced by students in the concept of quadratic equations, namely: 1) ontogenic obstacles occur due to students' inability to grasp the concept of quadratic equations. This is caused by a mismatch between the learning or knowledge intended to be constructed by students and their thinking abilities; 2) Didactical obstacles arise from the lack of coherence in the material, both in terms of the interconnectedness of quadratic equation concepts and the continuity of the thinking process, as well as the presentation of less-detailed materials; 3) Epistemological obstacles occur because students' knowledge related to quadratic equations is limited to specific contexts only.

Abstract

This research aims to describe students' errors in solving story problems related to quadratic functions and identify the underlying factors causing these errors. The research conducted is qualitative. The study took place in one of the junior high schools in South Kalimantan, involving 5 subjects from Grade IX. The research instrument used was three descriptive story problems—data collection techniques involved analyzing the answers to the descriptive test and conducting interviews. Based on the analysis, the types of errors made by the subject are as follows: 1) Misread-direction errors (30%): Students failed to read the instructions properly due to rushing or being unfamiliar with reading question instructions. 2) Careless errors (40%): Students made calculation mistakes due to lack of attention to detail. 3) Concept errors (20%): Students lacked understanding of quadratic function concepts due to insufficient study. 4) Application errors (33.33%): Students could not apply concepts and formulas effectively in solving problems due to a lack of comprehension of the subject matter. 5) Test-taking errors (66.67%): Students failed to restate information from the problem because of being in a hurry and unfamiliar with solving story problems.
