다국어 초록 (Multilingual Abstract)

The aim of this research is to attempt to extend previous work in this field by devising a set of intervention activities which could be used by teachers to help children to develop towards the commonly accepted scientific understanding of sound from constructivist strategies, and to compare the children`s ideas about sound between pre- and post- Intervention. A set of structured activities was then provided which should allow children to explore sound phenomena. Full sets of data were collected from 43 children in total(n=11 for grade 1, n=15 for grade 3, n=17 for grade 5). These data related to everyday sound, string telephone, drum, funnel and rubber band activities were analysed by some categorical schemes. The major findings of this study are as follows: 1. There are significant changes in children`s ideas over the interventions. These changes are most conspicuous in connection with sound production and sound transmission, The age group which show most distinctive changes are the grade 3 and grade 5. The most effective activities in promoting change of sound production are drum and rubber band. 2. Examining the individual changes of schematic chart show that a large number of children have developed their ideas in a way which can help them to develop scientific thinking.
