The Research And Practice Of Accommodation In Chemical Problem-solving

Guided by the Outline of Curriculum Reform in the Elementary Education, based on the theory of modern cognitive psychology, this thesis makes a deep study 'of accommodation in chemical problem-solving from the view of both theory and practice, aimed at present existing problems in chemical problem-solving teaching in high school.The whole thesis consists of four parts. In the first part I have analyzed the present situation and achievements on the research of psychology of chemical problem-solving, and have pointed out the reason why present chemical problem-solving teaching doesn't take in the achievements.The second part is on the theory plane. I have analyzed the meaning of accommodation in chemical problem-solving, the necessity and value of the study of accommodation in chemical problem-solving, the process of accommodation in chemical problem-solving (including five contacting links mutually: information-obtaining, crevice-perceiving, rule-bearing, problem-solving, process-anti thinking, and I think the rule- bearing is the vital link of the process of accommodation),the strategy of accommodation in chemical problem-solving (having strategy of subordination, strategy of conversion, strategy of fusion, strategy of induce etc).The third part is on the experiment plane. I have studied the process of student's problem-solving. Realizing the process of accommodation really exists in chemical problem-solving, while solving problem they really have to adopt the strategy of accommodation. The guidance from the teachers has an important effect on the students in adopting the rule-bearing path of solving problems.Finally, I have elaborated how to help students to gain the ability of chemical problem-solving in solving problem teaching. I have given some suggestions to chemical problem-solving teaching in high school. Chemical problem-solving teaching should guide the students to use the rule-bearing path of problem-solving often, should guide students to construct strategy of accommodation of chemical problem-solving, and then attain to the target of developing the students ability of analyzing problems and solving problems.
