Abstract

The mathematical reasoning ability of each student is very important to be able to make them use reasoning in patterns and traits, and perform mathematical tricks to produce valid generalizations, proofs, and statements. The activity of generalizing, proving, and making valid statements requires self-confidence. Confidence is in the form of Self-Efficacy and becomes an internal factor related to mathematical reasoning abilities. describing mathematical reasoning abilities in terms of students' mathematical self-efficacy is the aim of this study using a descriptive qualitative approach. Data collection techniques were questionnaires to measure students' self-efficacy, written tests to measure students' mathematical reasoning abilities, and interviews. The research subjects were 30 students of class XII MAN 2 Pekanbaru. The results of the study found that: (1) 26.67% of students with high mathematical reasoning abilities were accompanied by high or moderate self-efficacy; (2) 56.67% of students with moderate mathematical reasoning abilities are accompanied by high, medium, or low self-efficacy; (3) 16.67% of students with low mathematical reasoning ability are accompanied by moderate or low self-efficacy; (4) 43.33% of students can perform calculations based on certain rules; (5) 76.67% of students can do direct proof; and (6) 75.83% of students can provide valid arguments. It can be concluded that the level of mathematical reasoning ability is not always on the same level as students' self-efficacy, but the best mathematical reasoning ability is always followed by good self-efficacy. So, students' self-efficacy needs to be increased to be able to apply better mathematical reasoning abilities.

Abstract

The ability to think higher order is one of the curriculum demands that can train students' ability to solve problems and improve their experience in doing HOTS questions.The purpose of this study was to analyze student mistake in solving HOTS-type limit function questions. This research is a qualitative descriptive study, and the subjects of this study consisted of 24 students in class XI consisting of students with high, medium, and low abilities at SMA N 2 Bangkinang Kota. Data collection techniques obtained from tests and documentationhe analysis technique carried out involves grouping students based on high, medium, and low abilities. Based on the results and discussion, this study shows that there are three types of student errors: comprehension errors, transformation errors, and skill errors. Factors of student error in solving HOTS questions In the function limit problem, students have not been able to absorb information well, they have not been able to understand the meaning of the questions given, and they are not careful and less thorough in the process.
