다국어 초록 (Multilingual Abstract)

This study examined the effects of cooperative construction of portfolio on some biological concepts in elementary school. Children`s conceptions in classification of living organism, comparison, ecosystem, and adaptation to environment were explored. Cooperative activities in the construction of portfolio facilitated the acquisition of correct concepts. Especially, highly significant difference in the area of classification of living things appeared between the traditional and cooperative groups. When we compared the four concepts, the scores of cooperative group were higher than those of individualistic group. It was revealed that the individualistic construction limited the interactions among children, and children and teacher, while the activities of cooperative construction of portfolio activated reflective thinking of children. These results suggest the importance of active and various interactions when children learn science concepts. There were no significant differences between the individualistic and traditional groups. As the interaction among children-children and children-teacher activated, children corrected, modified, or complemented their portfolios and became more enthusiastic in such activities. Whole results implied that cooperative and interactive activities have positive influences on the acquisition of correct science concepts.
