Analysis of Student Errors in Solving Quadratic Equation Problems at SMAN 1 Polombangkeng Selatan Takalar Regency

Abstract

This research is descriptive qualitative research. The subject of the study was students of class X3 SMA Negeri 1 Polombangkeng Selatan, Takalar Regency, which consisted of 30 students. A total of men were 15, and a total of women were 15. The data collection technique used in this study is in the form of an achievement test with the subject matter of quadratic equations and an interview test in connection with the obstacles faced in solving problems. Based on the learning outcomes test, data on mistakes made by students were obtained, namely, the concept level (A1) of 47.66%, which was categorized as moderate; the principle errors (A2) of 49.44%, classified as moderate; algorithm errors (A3) of 68.89 % categorized as high, and the language interpretation error (A4) of 44.44% which can be categorized into the moderate level. Therefore, the mistakes made by students in solving problems are caused by a lack of mastery of the prerequisite materials, a lack of interest in mathematics subjects, and a lack of doing the various exercises.
