During their past daily life and studies,junior high school students have formed lots of individual experience.Some of this can be the beginning of their knowledge,but much of their experience goes against the current scientific theoires.This can be called the pre-science concepts formed in students'brains in the past.Students never have any doubt about their pre-science concepts.While analyzing the situation that the students'pre-science concepts affect their study about physics in the current teaching in junior high school,the thesis puts forward some studying strategies,in which the"Positive Moving"is promoted using the positive side of the students'pre-science concepts and the"Negative Moving"is converted to strengthen their study of physics conceps.Physics teachers in junior high schools should pay enough attention to the students'former cognition experience during their teaching.To start with their pre-science concepts, students should be guided ingeniously to integrate their new concepts with their former ones closely.Their correct science concepts should be enriched and developed by assimilation to expand their own knowledge structure.At the same time their erroneous pre-science concepts should be converted by conformance.They should also get to understand the science concepts totally and all-sidely by converting the"Negative Moving"of the pre-science concepts and promoting the"Positive Moving"of it rationally to deepen the students'comprehension to the science concepts. |
