Solve The Problem Of High School Chemistry Openness

"Problem solving"is an important kind of human's cognitive activity. To develop the teaching research of "chemical problem solving" is a chemistry education for all-around development important aspect, also is the important question which the current our country chemistry curriculum reforms needs earnestly to discuss. The chemical open-ended question has strong inquisition into the natural, different from the traditional closed question. It has the specially vital role in raising the student's fine thought quality as well as the independent solution actual problem ability. Discussing the student's solution of chemical open-ended question is the chemistry education's urgent need.Under the directing of the basics in the Cognitive psychology and Information Processing psychology, joining open-ended question's basic type and the characteristic, the author designed the chemistry open-ended question investigation test for senior students and the open-ended chemistry question test material. With the motheds of questionnaire measurement and verbal protocol by group test and case study respectively, the author conducted the preliminary study on the solution to chemiscal open-ended question for high school students. The results show:First, many kinds of factors influence solution to chemical open-ended question for high school students. Among them, the complete knowledge structure is the important foundation and the fine thought quality is the essential factor for solving the chemical open-ended question, the higher information accomplishment and the migration ability is the important safeguard for effective addressing chemical open-ended question.Second, the high school students'strategy to solve chemical open-ended question is unitary. The pattern recognition strategy is they solves time the question commonly used strategy, when uses is often easy to cause the negative migration; The analysis recursion strategy is they solves the strange question effective strategy, when uses frequently the blind acquisition question space, consumes when are more.Third, in chemistry teaching in order to enhance the student to solve chemical open-ended question ability, may adopt the teaching strategy mainly has following three aspects:(1) to help students to construct the construction knowledge network;(2) to raise students'fine chemistry thought quality;(3) to pay attenion to strategical knowledge teaching.
