Investigation of critical mathematical thinking ability, visual thinking and self-efficacy students' in trigonometry

Abstract

This study aims to investigate how students' the ability of critical mathematical thinking ability, visual thinking and self-efficacy in the current trigonometry. Data were collected through the students' answers, self-efficacy questionnaire and interview. The results obtained are then analyzed to see the students' ability level in trigonometry. The result showed the students do not yet have the critical thinking ability are good but have good visual thinking ability in trigonometry. This is because students do not have the concept of underlying problem solving well. Furthermore, students feel less confident in their mathematical ability. This is evidenced of the analysis self-efficacy questionnaire. The results of this study encourage us as prospective teachers to find teaching methods that can help students understand the concepts of trigonometry well so that students love and eager to solve the problem of trigonometry.
