Abstract

The aims of this research are to know about mathematical problem-solving ability student of senior high school towards trigonometry material, mathematical reasoning ability student of senior high school towards the statistical material, and self-efficacy ability in mathematics learning students of a senior high school. The research used descriptive qualitative research, and the research object is XI IPA of senior high school. The chosen students are students who have learned about trigonometry and statistic. The chosen students who become sample are 30 students. In this research, the technic used tests, with the instruments used are question and questionnaire. The test consists of 5 question about mathematics problem-solving, 5 question of mathematical reasoning, and 40 questionnaires of self-efficacy ability. According to the results of our research, it can be concluded that the students' ability in problem-solving and reasoning mathematics is low, while students' ability in self-efficacy is good. It can be seen that the students have good self-efficacy ability along with the problem-solving ability and reasoning ability that are still low.

Abstract

This study aims to determine the reasoning abilities of high school students and describe the types of student errors in solving trigonometry problems. The form of research used is descriptive qualitative research, with the object of research being students of class X Language at SMA Albidayah. The selected students are students who have studied trigonometric material. The students who were sampled were 24 students. With the selected sample is a sample that has high, moderate and low mathematical abilities seen from academic achievement. In this study, students were given tests with instruments in the form of questions consisting of 4 items based on students' mathematical reasoning. Based on the results of this study, it can be concluded that the results of the test analysis of students' mathematical reasoning abilities in trigonometry material are said to be sufficient, namely by the percentage of 43.739%. The type of error based on the Watson category is carried out by students with high, medium, and low ability, namely incorrect data / incorrect data, improper procedures, incorrect data, and other than seven errors / others.
