Identify student mathematical understanding ability through direct learning model

Abstract

The ability of mathematical understanding is an important basic skill possessed by students. The purpose of this study is to identify the ability of the students mathematical understanding through direct learning model. The type of research is descriptive qualitative research. The subjects were 6 students divided into 3 criteria: students who have good, medium, and low mathematics skills. The learning process is done by using direct learning model. All students were given diagnostic questions and the results were corrected for analysis. The classification of misconceptions made by students uses four errors, namely: (1) Basic error that is the basic concept mistake or misunderstanding of the problem; (2) Appropriate error of understanding some concepts; (3) Missing information that is not able to answer completely the problem given; (4) Partial insight error caused by miscalculation or carelessness. Based on the result of the research, it is found that in solving basic mathematics problems, students make mistakes of mathematical understanding on basic error type, missing information, and partial insight. After being given direct learning, misunderstanding of students decreased.
