Abstract

This study aims to determine whether there is a difference in mathematical problem-solving ability between students who learn using the Problem Based Learning learning model and students who learn with direct learning when viewed from student self-efficacy. The design used is a factorial experimental design. The sampling technique is Cluster Random Sampling. Data collection techniques used are tests, questionnaires and observations. The population in this study were all students of class VIII of SMP Negeri 1 Putussibau. The data collection instruments used were pretest and posttest questions on mathematical problem-solving ability, self-efficacy questionnaires, and teacher and student observation sheets. The analysis used was a two-way ANOVA test with the same cells. Based on the results of the data analysis, it can be concluded that: there is a difference in mathematical problem-solving ability between students who learn using the Problem Based Learning learning model and direct learning, high, medium and low self-efficacy have different mathematical problem-solving abilities, there is no interaction between learning methods and self-efficacy on mathematical problem-solving abilities, meaning that self-efficacy does not depend on learning methods.

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.
