Students Self-Efficacy in Solving Geometric Problems: Case Study in Private Junior High School in Malang City

Abstract

This research aims to describe junior high school students' self-efficacy in solving geometry problems. Instruments include the Self-Efficacy Questionnaire (SEQ) and the Geometry Problem Solving Test (GPST). The research instrument has been validated by three senior lecturers with doctoral degrees in mathematics education. The readability test was carried out by two mathematics teachers and two students from State Junior High School in Surabaya, purposively selected class 9 of Junior High School Muhammadiyah 4 Malang City, consisting of 6 male students and 3 female students who were divided into low subject, medium subject, and high subject groups. The research results showed that low subjects were only capable at the analysis stage, but not at the exploration, planning, implementation, and verification stages. Medium subject is capable at the analysis and exploration stage, but not at the implementation and verification stage. High subjects are capable of all problem-solving indicators. Each subject has different self-efficacy, as well as geometry abilities. It is recommended that future researchers develop and test other subjects according to the education level of junior high school students.
