It is generally accepted that children develop their own ideas about what is happening in their world through what they see with their own eyes. Children often hold ideas that are quite different from acceptable science because they construct alternative meanings from their own individual experiences. The role of the teacher is much more complicated than telling a child that their idea is wrong and asking them to accept what the teacher says, especially if it conflicts with what they have seen with their own eyes. In this article, the authors share their work on models and how a DVD they created can help teachers include games, models, and analogies in one's teaching. The main purpose of a game, model, or analogy is to help children understand difficult ideas that cannot be explained easily or demonstrated practically. (Contains 2 figures.)
