영문 초록

The purpose of this study was to analyze the middle school students conceptual structure change and misconception about vegetative organ of plant. The subjects were 131 middle school students. To make a statistical analysis of their conceptual structure, x 2 -test was selected, and another concept maps they drew after the experiment were analyzed to see if they had any misconceptions. The findings were as follows: The students investigated had a conceptual structure of their own about the vegetative organ of plant. They had the best conception of photosynthesis (70.2%), followed by fibrous root (54.2%) and movement channel/conveyance (46.6%) before the experiment. The most dominant conceptions that appeared in their concept maps were about the absorption of roots, the conveying action of trunk and the photosynthesis of leaves. After the expository instruction, 80.9 percent showed a change in conceptual structure, and their change was statistically significant (p<.05). In terms of the vegetative organ of plant, there were seven typical misconceptions. The students mistook the roles of vessel and sieve tube for absorption.
