3~6歲幼兒浮力的前概念及其對幼兒科學(xué)教育的啟示
[Abstract]:Since the 20th century, more and more researchers have paid attention to children's original understanding of the surrounding world, and have constantly revealed that children's cognitive ability beyond people's imagination. Our kindergarten education also emphasizes that it should be based on the existing experience of young children. However, in real life, it is easy to unwittingly underestimate young children, and do not really find out the existing experience of young children. This study attempts to find out the present situation of children's pre-concept of "buoyancy", in order to make efforts to further understand children and reflect on the existing teaching. In this study, a total of 48 children in large, middle and small classes in a kindergarten in Chengdu were selected as the research objects, and the present situation of children's understanding of ups and downs and floatation was explored by situational interview, and the teachers' ideas about related teaching were obtained by interviews with kindergarten teachers. This study shows that 3 years old children tend to think that the weight, size and water quantity of the object are the main reasons for the "floating", "sinking" and "suspension" of the object in the water. According to the state of the object in the water (motion state, relative position, etc.), it is determined whether the object is subjected to the buoyancy and the direction and size of the buoyancy. The understanding of the relationship between object and water will also affect the judgment of the existence of buoyancy and the understanding of the three elements of buoyancy. It is generally believed that the content of children's science education should come from the children's life. In the teaching, children should take the initiative to explore, attach importance to the process of children's exploration, put the emotional attitude goal in the first place, and think that children do not need to learn the core scientific concepts. The role of science education in early childhood is to enable children to obtain a wealth of science-related experiences. The existing teaching of ups and downs does not involve related concepts. According to the findings of this study, the researchers make some thoughts on children's science education, such as whether teaching can involve "buoyancy" and the problems existing in the existing "ups and downs" teaching activities, and try to put forward some suggestions that "ups and downs" activities should carefully prepare materials and give sufficient time for children to fully experience them.
