| Summary: | 碩士 === 國立高雄師範大學 === 物理學系 === 89 === Abstract
The main purpose of this study is to investigate children''s concept and sub-concept developing of Newton’s Third law. A semi-structured interview was used to find out the factors that affected the thinking about it from 54 children.
The results were found:
1. In those sub-concepts of Newton’s Third Law 「action force」、「reaction force」、「direction of action and reaction force」、「magnitude of action and reaction force」and「synchronism of action and reaction force」, children’s thinking were sequential order different between dynamic and static situation.
2.The conceptual development of children on Newton’s Third Law positively related to their grades and their CMS level.
3. The conceptual development of children on Newton’s Third Law, which present in dynamic motion, is more acceptable than static motion.
Key words：Newton’s Third Law、concept、action force、reaction force、conceptual development.
