Analysis of Learners' Errors in Working on Formative Tests on the Topic of Quadratic Equations and Functions
Abstrak
The purpose of this study was to determine and analyze the errors of students in working on formative tests on the topic of Equations and Quadratic Functions by completing the perfect square root method and the ABC formula. This type of research is descriptive research with a qualitative approach. In this study, the subjects were taken from 12 students of class XI IT SMKS Dar El Hikmah Pekanbaru, each of which consisted of 2 students from the upper, middle, and lower groups. In this study, data collection techniques based on observation, written formative test questions, and interviews were used to determine students' errors in solving the topic of Quadratic Equations and Functions. In this study, it can be concluded that students' errors in solving the topic of Quadratic Equations and Functions with the method of completing the perfect square root and the ABC formula are the lack of understanding of the concept of the method, the lack of assignment of the topic, and the lack of students' mathematics learning so that students make many mistakes in solving problems.
