Abstract

The purpose of this research is to find out the errors and factors that cause student errors during working on the SPLDV. This research uses a qualitative with a qualitative descriptive type of research. The research subjects were all students of class VIII A MTs Persiapan Negeri of Tagor Island Village, and selected 3 students as interview subjects. The research instrument consisted of a written test and an unstructured interview. The results of the analysis were found, 4 students getting predicate B made a few mistakes with a value range of 84-92 fulfilling the KKM, it was found that 8 students getting predicate C and D made a lot of mistakes with a value range of 75-83 and <75 scores below the KKM. The conclusion of the study was that there were 95.65% conceptual errors and 86.95% errors in principle and operation. Factors that cause errors are: not understanding the concept, only focusing on the examples given by the teacher. do not master algebraic operations. careless in answering questions.
