Abstract

Effective mathematical communication plays a crucial role in the resolution of mathematical problems. Despite efforts to enhance mathematical communication, the success rate among students remains relatively low, a situation that is closely associated with their levels of self-efficacy. The purpose of the study was to describe students' mathematical communication skills based on self-efficacy. The research adopts a descriptive qualitative method. The subjects of this study consisted of seventh-grade students who had studied the material on flat shapes. According to the outcomes of the self-efficacy questionnaire, students are classified into three categories: high, medium, and low. Each category was taken by one student as a respondent with the purposive sampling technique. Data collection techniques include tests, questionnaires, and interviews. Data analysis techniques include data reduction, data presentation, and conclusion. The analysis indicated that students exhibiting higher levels of self-efficacy displayed enhanced mathematical communication skills when compared to their peers who possessed lower levels of self-efficacy. This study revealed a significant relationship between mathematical communication and self-efficacy. Students with elevated levels of self-efficacy display enhanced proficiency in mathematical communication skills in comparison to their peers who possess medium and low levels of self-efficacy.

Abstract

Fuzzy thinking means the thinking process with confusion between understanding and not understanding. This research was conducted to find out the students' experiences of fuzzy thinking in mathematics communication in SMP Negeri 2 Banyumas. This was a descriptive qualitative research and the subjects were taken from the students of class 8 C using snowball technique and T.O.L (Think Out Loud) that fulfilled the criteria of fuzzy thinking either the correct one or the incorrect one. From the results, there were 2 students with correct fuzzy thinking and 4 students with incorrect fuzzy thinking. The data were collected using tests, interviews, and documentation then analyzed using Miles and Huberman model consisting of data reduction, data display, and conclusion. The results showed that: 1) the thinking process of the respondents with incorrect fuzzy thinking experienced a change. At first they were able to think correctly, but after the reflection, they were not able to explain correctly, so the answers did not reflect their understanding absolutely; 2)the thinking process of the respondents with correct fuzzy thinking experienced a change. At first they were not able to do the test correctly, but after the reflection, they were able to finish it correctly.
