How Does Problem-solving Method Affect Students’ Self-confidence and Mathematical Understanding?

Abstract

This study aimed to determine the effects of problem-solving method on students’ self-confidence and mathematical understanding in learning. This study used quantitative and qualitative methods. The research followed the process of quantitative calculation from instruments about mathematical understanding and described students’ self-confidence, analyzed using Rasch with the WinSteps application. This research was conducted at SMPN 30 Jakarta with class VIII students as the research population. Based on this population, 34 students were selected as the sample with a cluster random sampling technique. Based on the data obtained, it was known that there is a significant effect of problem-solving methods on mathematical understanding. Meanwhile, Rasch data analysis showed a high category for the relationship between understanding and self-confidence of students by 60%. This proved that the effect of the problem-solving method on self-confidence and mathematical understanding is directly proportional.

The Influence of Guided Discovery Learning Assisted by Fractional Wheels and Learning Motivation on Improving The Critical Thinking Skills of Grade V Students at SD Negeri 1 Dagan Purbalingga

“…The purpose of learning mathematics is for students to have logical, critical, analytical, meticulous and meticulous abilities, responsible. Related to critical thinking skills according to (Rahayuningdewi & Faradillah, 2020) mathematics and critical thinking skills are two things that cannot be separated, because mathematics is understood through critical thinking and critical thinking is trained through mathematics. If students have good critical thinking skills, they will be able to solve problems well so that students can solve problems in the real world and are able to face global competition in the 21st century.…”
