수학적 오개념 발생에 관한 일 고찰 - 극한 개념을 중심으로 -

The purpose of this study is to investigate the mechanism of the conflict between concept image and concept definition in the learning of limit concept. Several investigations which examine the limit concept image of students demons - trate individual concept image differing from the formal theory and containing factors which cause cognitive conflicts.

The mathematical limit concept is the final product of limiting process which extends knowledges of functions. And then it provides infinity concept which makes possible to under - stand other concept onthe basis of limit.

Even though limit concept is a theoretical basis for high- school mathematics and college mathematics, many students do not understand on its basic concept or do have misconception on it.

The conclusion of this study is that most of high school students did not understand the concept of limit correctly. Therefore, teachers and textbooks need to emphasize the definition and the concept of limit and to present examples during the instruction of mathematical limit concept.
