Study On Modeling Abilities Of Chemistry Problem Solving In High School Students

To improve high school students'Modeling Abilities of Chemistry Problem Solving is to put cultivating students'ability of solving factual problem of chemistry into effect. Putting modeling teaching into chemistry will not only help students know and understand chemical knowledge but also help them apply scientific method, improve Scientific Literacy.To cultivate high school students'Modeling Abilities of Chemistry Problem Solving effectively, on the basis of survey and procedural knowledge in modeling and applying, we conclude that high school students'Modeling Abilities of Chemistry Problem Solving includes the ability to construct model, the ability to assess model, the ability to apply model; According to the three elements, we prepare a questionnaire to test high school students'present Modeling Abilities of Chemistry Problem Solving and the factors, on which we put forward teaching tactics.Our researches get following results:First, the ability to construct model, the ability to assess model, the ability to apply model are the integral elements of high school students'Modeling Abilities of Chemistry Problem Solving.Second, at present most high school students have low Modeling Abilities of Chemistry Problem Solving and the development of each element of Modeling Abilities of Chemistry Problem Solving is not balanced, of which the ability of applying model is higher, and the ability of assessing model is lower.Third, there is no significant differences either total chemistry model abilities in problem solving or each element; students'chemistry record relates to their Modeling Abilities of Chemistry Problem Solving, chemistry model abilities in problem solving of excellent learning and students with learning difficulties exit significant differences especially the ability of assessing model. It accounts for that students'Modeling Abilities of Chemistry Problem Solving strong or weak directly affects efficiency and quality in students'study.Forth, There are many factors affect students'Modeling Abilities of Chemistry Problem Solving, in which students'chemical knowledge,students'Abstract thinking ability,students'problem representation ability,students'self-regulated ability of modeling in chemistry problem solving are the most important factors to improve their Modeling Abilities of Chemistry Problem Solving.Fifth, we can infiltrate modeling method in chemistry teaching:(1) integrate chemistry content to carry through modeling method education;(2) make use of history of chemistry to to carry through modeling method education;(3) using sample to carry through modeling method education.
