Abstract

This study aims to find out clearly and in detail as well as in-depth answers to the results of problem solving analysis of high school students on the subject matter of algebraic derivatives in terms of self-confidence. The method in this study used a qualitative descriptive method. The population in this study were all students of class XI SMA Yayasan Atikan Sunda Bandung in the academic year 2021/2022. The sample used was purposive sampling based on the criteria of high, medium, and low self-confidence as many as 4 students. Data collection techniques in this study used mathematical problem solving tests, non-confidence tests and interviews. Data analysis used is triangulation technique. The results of this study indicate that in analyzing the material derived from algebraic functions, the following things are obtained: 1) Students who have low self-confidence can meet the criteria according to the problem-solving ability indicators according to Polya^s theory, which are quite able to understand problems, can plan, implement problem-solving plan and can see the answers back. 2) Students who have moderate self-confidence can meet the criteria according to the problem-solving ability indicators according to Polya, namely being able to understand problems, be able to make plans, carry out problem-solving plans, and can review the truth of all answers, and 3) Students who have self-confidence High school students have difficulty understanding the problem, are unable to plan, but can carry out the settlement plan and can see all the answers. From these learning outcomes, it can be said that if students have high self-confidence, students may not necessarily be able to master mathematical solutions, and vice versa.
