Abstract

Abstract

This study aims to determine the mathematical self-efficacy of students by giving feedback on the graphs of trigonometric function material. This study records aspects of the magnitude, aspects of strength, and general aspects. This study uses a description method and uses a survey research form. The research sample was class X which consisted of 31 students and was chosen based on the recommendations of the mathematics teacher. Data processing techniques used are indirect communication techniques and direct communication techniques. The thing in this study is a mathematical self-efficacy questionnaire and interview guidelines. The results showed that students' mathematical self-efficacy by giving low feedback with a high category percentage of 54.83%. Merging data shows that mathematical self-efficacy in each aspect, namely the aspect of magnitude, aspects of strength, and general aspects in the medium category. While the number of medium categories for the aspect is as much as 55%, the power aspect is 68%, and the general aspect is 48%.
