| Popis: | 87 The main purpose of this study is to investigate children’s understanding about the content of Newton’s Third Law, and to describe children’s conceptual development on Newton’s ‘Third Law. Semi- structured interviews was adopted with small samples to find out the factors which affected children’s thinking about Newton’s Third Law. Based on the findings of interviews, an instrument with DLPT examining technique was developed and was administered to a big-scale sample of 2734 grades three to eight students. They were randomly drawn between grade three and grade eight. The data were collected and analyzed by means of children’s written responses. The results revealed: 1.The concept development of children on Newton’s Third Law followed the sequential order of from “recognition of action force”, to “recognition of action-reaction forces”, to “awareness of the strengths of action-reaction forces”. 2.The concept development of children on action-reaction forces positively related to their grades and to their CMS levels, However, children’s cognition on the strengths of action-reaction forces did not follow along with the growth of neither grades nor CMS levels. 3.Sex made significant difference on children’s recognition of reaction force. 4.The concept development of rural children on Newton’s Third Law was slower than the development of children of other areas. |
