Abstract

This study aims to describe the ability of social arithmetic problem solving in terms of self-confidence of seventh grade students of SMPN 20 Mataram in the 2022/2023 academic year. This type of research is qualitative and quantitative with 7 students as subjects. The instrumens used are self-confidence questionnaire, social arithmetic test, and interview guidelines. The data analysis techniques used are data reduction, data display, and conclusion drawing/verification. The stages of problem solving used are problem solving according to Polya, namely understanding the problem, developing a plan, implementing the plan, and checking again. The results showed that subjects with high self-confidence and high problem solving ability were able to carry out the four stages of problem solving according to Polya. Subjects with high self-confidence and moderate problem solving ability were able to carry out three stages of problem solving according to Polya. Subjects with high self-confidence and low problem solving ability were able to carry out two stages of problem solving according to Polya. Subjects with moderate self-confidence and high problem solving ability were able to carry out three stages of problem solving according to Polya. Subjects with moderate self-confidence and moderate problem solving ability were able to carry out three stages of problem solving according to Polya. Subjects with moderate self-confidence and low problem solving ability were unable to carry out all stages of problem solving according to Polya. Likewise, the subject with low self-confidence and low problem solving ability.

Abstract

This study aims to describe students' errors in solving number pattern word problems. Error analysis was done based on Newman error analysis and reviewed from reflective-impulsive cognitive style. The type of this research is descriptive qualitative. The subjects in this study were 8th grade students in one of the Junior High Schools in Mataram city selected by purposive sampling technique. The instruments used were the MFFT test, written test of word problems, and interview guidelines. Data analysis techniques are data reduction, data presentation, and conclusion drawing. The results showed: (1) Reflective students made errors with very low categories at the reading and comprehension stages of the problem, low categories at the problem transformation stage, medium categories at the process skills stage, and high categories at the encoding stage. The causes of errors made by reflective students are running out of time, focusing too much on one problem, and not mastering the material tested; (2) Impulsive students make mistakes with a low category at the reading and comprehension stage of the problem, a medium category at the problem transformation stage, a high category at the process skills stage, and a very high category at the encoding stage. The causes of errors made by impulsive students are rushing, lack of thoroughness, not thinking deeply, not checking the answers, and not checking the answers.
