일차함수 개념의 이해에 관한 연구

Abstract

This study looks into what concept images second-year students in middle school have about functions and what their erroneous concepts are by examining how much they understand the concept of functions, and aims to improve the teaching-learning method to correct their wrong concepts. For this purpose, the following research questions were set up. 1. What do the students think about functions? 2. To what extent can a point given on a coordinate plane represent the pre-image of a function and its corresponding image? 3. How much do they understand linear functions, graphs, domains of definition and ranges?

To answer these research questions, the researcher randomly chose 4 classes (75 students) in two schools in Busan and carried out research.
