Abstract

This study aims to analyze student’s difficulties in solving problems related to relation and function. The research employed a descriptive method with a qualitive approach in the form of a case study. The subjects of this study were 35 ninth-grade students of SMP Negeri 14 Pontianak. Data were collected through essay tests and interviews, then analyzed descriptively to identify the types and causes of students’ learning difficulties. The result showed that students experienced three main types of difficulties. First, conceptual difficulties (40%), indicated by a lack of understanding of the definition of functions, relations, and mathematical symbols. Second, difficulties in applying principles (67%), including errors in determining function formulas, performing calculation, and lack of accurary in solving problems. Third, difficulties in soving verbal problems (40%), reflected in students’ inability to draw function graphs, determine coordinate axes, and understand problem-solving procedures. These difficulties were caused by a lack of conceptual understanding, weak computational skills, and low accuracy in reading and solving problems. Therefore, It is necessary to implement learning strategies that emphasize conceptual undertanding, continuous practice, and improvement of students’ accuracy.

AbstractLearning difficulty is a condition where students cannot study well. The purpose of this study was to analyze students' difficulties in solving mathematical problems in probability theory courses. This is qualitative descriptive research. The subjects in this study were the sixth-semester students of the 2020-2021 academic year in the mathematics education study program who took the opportunity theory course at IKIP PGRI Pontianak. The research instruments used were tests and interviews with data collection techniques using measurement techniques and direct communication. The data analysis technique used is data reduction, data presentation, and conclusion. The results showed that students with a high ability (M1) experienced a little difficulty in learning, namely in solving mathematical understanding questions on instrumental indicators. Furthermore, students in the moderate category (M2) lack understanding of the concept of opportunity and its instrumental understanding, while relational understanding is good. It was found that students in the low category (M3) did not understand the concept of probability, especially regarding the writing of sample space members and events, could not calculate the probability value, and did not understand the integral concept so they were wrong in determining the final expected value, and did not understand the concept of the probability density function.

Abstract

Penelitian ini menganalisis kesalahan siswa kelas VII A SMP Negeri 2 Mandor dalam memecahkan masalah berpikir kritis pada materi bilangan pecahan menggunakan pendekatan Newman. Kemampuan berpikir kritis sangat penting untuk pengembangan keterampilan tingkat tinggi siswa, namun kenyataannya kemampuan ini masih rendah di kalangan siswa, yang berdampak pada kesulitan pemecahan masalah. Pendekatan Newman digunakan untuk mengidentifikasi dan mengklasifikasikan kesalahan siswa pada lima tahapan: membaca, memahami, transformasi, keterampilan proses, dan menyimpulkan jawaban. Metode penelitian ini adalah kualitatif deskriptif dengan studi kasus. Data dikumpulkan melalui tes tertulis dan wawancara dari 26 siswa yang dikategorikan berdasarkan tingkat kemampuan berpikir kritis (tinggi, sedang, rendah). Hasil analisis menunjukkan bahwa kesalahan terjadi di semua tahapan pendekatan Newman, terutama pada pemahaman, transformasi, keterampilan proses, dan penarikan kesimpulan. Faktor-faktor penyebab kesalahan meliputi pemahaman konseptual yang lemah, keterbatasan keterampilan berpikir kritis, metode pembelajaran yang kurang tepat, serta faktor metakognitif dan kecemasan siswa. Kesimpulan utama adalah siswa menunjukkan pola kesalahan yang signifikan, yang perlu diatasi melalui perbaikan metode pembelajaran dan penekanan pada pengembangan kemampuan berpikir kritis.
