Abstract

The investigation on learners' misconception on the area of geometry -In middle school- Jeon Min-jeong Advisor : Prof. Han Seung-gook Ph.D. Major in Mathematics Education Graduate School of Education, Chosun University

The purpose of this study is to find the errors in geometry of students who have completed their second year in middle school For this purpose, I established two research problems. (1) What forms of errors exist in problem-solving in geometry? (2) What is the adequate teaching methodology in response to these problem-solving errors? For a closer analysis of the research I set as a research pool 65 students in two second grade classes of Yeo-do middle school, located in Yeo-su of the Chonnam province. The test material used to examine the students’ errors in geometry and the survey sheets regarding students’ interest in mathematics were created authentically by the researcher ?C I. As a result of analyzing the results of the test material, the errors could be categorized into the following four categories: ↘: Lack of core knowledge, ♭: wrong application of operators, ♩: unanticipated wrong answers, ♪: ambivalent error. The following results were sought from this study. First, students tend to misunderstand or poorly understand the definitions, theorems and new symbols, consequently failing to use them properly Secondly, they tend to absentmindedly confront word problems or fail to adequately understand them and consequently fail to produce the right answer Thirdly, instead of thinking in many ways, they tend to attempt to solve problems quickly and easily with only their instincts and estimations.
