Abstract

Until nowadays, national exams are still held every year. Based on the result of National Exam in 2015, one of the national exam questions which is difficult is the question of congruence. This study aims to find out the kinds of difficulties and factors causing the difficulty of class IX students of SMP 2 Pundong in completing the national exam questions about congruency. Difficulties that want to be known to berelated to concepts and principles in equality. The research method used is descriptive qualitative. The research subject was selected based on the students’ errors in completing the similarity diagnostic test given to them. Qualitative data is collected from the documentation and interview results . Data analysis was carried out qualitatively. The results of the analysis show that student difficulties include: difficulty interpreting information in the problem, difficulty understanding concepts and principles in congruence, and error operating. The difficulty of students in solving problems of congruence concerns the weakness of understanding concepts and principles in congruency. Factors that cause student difficulties, namely a lack of variation in the exercise of congruency problems that link all concepts taught to students.
