The Research On Solving Adduction-Problem Of High School Students In Chemistry

Adduction-Problem is common problem. Some physical quality can be adducted, for example:quality and amount of substance,Some chemical equation can be dducted, Some chemical equation can not be dducted. But some physical can not be adducted, for example:density and volume. One of the major subjects of chemistry teaching in New Course Reformation is how to develop the students' ability of analyzing and solving problems, which depends on the information processing when students deal with the questions.The dissertation is based on the theory of Problem-Sloving. The writer designed and conducted three experiments in order to find how high school students solve adduction-problem in chemistry.Experimentâ… : What kind of relationship exist between original chemical knowledge and adduction problem? Design a test for the representation of inference questions of adduction-problem in chemistry to analyze the procession of students recognizing the diagrams, the meanings and the main point of the questions;Experimentâ…¡: Three kinds of students solve the adduct-problem exist differences. Communicate with students after the experiments and further study whether students verity their results.Experimentâ…¢: Communicate with students after the experiments and further study whether students verity their results.
