The Study On Solving Problems Of Chemistry Bond In High School

In this paper, on the basis of theoretical overview with cognitive psychology theories and views, using the sample test for guidance, thinking aloud method and interview method, knowledge mastering of chemistry bond of the high students, the solutions and process of the relevant problems and the thinking process were studied. According to the actual situation of the grade, the researchers summarized the knowledge system of chemistry bond and made up a testing paper. Then according the score of the students, three categories were made among those students, which were efficient students, mid-efficient students and inefficient students. Though testing the students, investing their thinking process, the researcher analyzed the test data and finally came to three conclusions:First, the level of mastering knowledge of chemistry bond was different among the three categories students. Efficient students were mainly in the applied and understanding level; mid-efficient students were in the understood and memory levels; inefficient students were in the memory and understanding level.Second, there were differences among the three categories of students in solving problems of chemistry bond and the thinking processes were different. In the process of resolving problem, efficient students could analyze and solve the problems by themselves or could solve the problems only a little guidance. Mid-efficient students also could solve after hinted. Inefficient students could not solve the tough question which they thought it was tough after hinting a lot. There were three reasons of the differences.Third, through this research, the researcher drew some inspirations for the teaching of chemistry bond and research prospects for the future.
