Concept Map In The "Amount Of Substance" Problem Solving Application Research

"The amount of substance" problem solving level according to concept itself mutual connection degree division, a single, solitary concept for the low level of cognitive, namely the first level; Multiple concepts associated with each other for the medium level of cognition, namely the second level; In the complex situation through quantitative measurement connections for the concept of together high level of cognitive, namely the third level.According to the analysis, the student knowledge background in amount of substance's study, in the knowledge of three level problem solving difficulties are often. The introduction of the concept maps for a variety of disciplines offer a convenient, the teaching of chemistry discipline has also been trying to carry concept map used in chemistry teachingThis research mainly inspects content for;(1) concept map and "amount of substance" single, isolated concept cognitive and problem solving related degree.(2) concept map and "amount of substance" multiple concept interconnected together problem solving related degree.(3) concept map and "amount of substance" complex situation through quantitative measurement connections together problem solving related degree.Strive to references as a base, using investigation method and experimental verification exploration. Explore concept map and "amount of substance" problem solving related degree, combining with the middle school teaching actual situation, study design a practical stronger "amount of substance" concept system, aiming at improving the students' teaching strategies for effective learning "amount of substance" concept system efficiency.
