Published: June 2021

Abstract
This study aimed to describe the students’ problem-solving ability in solving Geometry problems. This research was a qualitative descriptive study with 6 students as research subjects at SMP Negeri 1 Piyungan Bantul. The data collection methods used in this research were tests and interviews. This research used the triangulation method to determine the validity of data which was obtained by the researcher. The results showed that the percentage score for the indicator of understanding the problem was 31.48%, planning strategies to solve problems was 57.41%, implementing strategies to solve problems was 55.56%, and concluding by 31.48%. At the level of problem-solving ability, there is one high category student, 3 medium category students, and 2 low category students. This is because students lack self-confidence, lack of understanding of problems, weakness in understanding concepts, principles, and mathematical formulas of geometric material, and lack of skills in calculations. Therefore, it is necessary to provide more and more complex questions so that students are familiar with various kinds of non-routine questions. Also, it is necessary to have an understanding of mathematical concepts, principles, and formulas so that they do not have a negative impact on students in solving advanced material geometry problems.

AbstractThis qualitative research purpose to analyze the mathematical representation ability of students in solving problems viewed from the level of self-efficacy. This research was conducted on 6E grade of mathematics education students at the University of Singapore Karawang. This research is focused on the ability of visual representation, equations representation or mathematical expressions, and words representations or written texts as seen from the level of student self-efficacy. The dimensions of self-efficacy include magnitude, strength, and generality. This study uses a qualitative approach with data collection techniques such as tests, questionnaires and interviews. The results showed that the ability of mathematical representation is very important and needed by students in understanding material and solving problems, if the ability of mathematical representation is lacking then it causes a lack of student understanding of the material given so that students have difficulty in working on given problems. A good mathematical representation ability is supported by good student self-efficacy, with optimism and never give up in working on any given problem by thinking of strategies for solving the solution.
