Experimental Study On Cultivating Chemical Thinking Method Based On Thinking Map In High School Exercises Teaching

Thinking Maps is a visual learning tool which is developed by David Hyerle in 1988 to visualize learners' implicit thinking.This new type of learning tools is often seen in foreign research,while it is rarely studied in domestic research.Thinking Maps covers eight subgraphs and each one represents a way of thinking.Reasonable choice of thinking Maps and flexible use can solve some of more comprehensive chemical problems.Thinking Maps is of great help for the students to master the way of chemical thinking.In view of the above opinions: First of all,reviewed the literature on the study of Thinking Maps at home and abroad,give the concept of both Thinking Maps and the chemical thinking method.At the same time,based on the analysis and collection of related literature,combing the theoretical basis of cultivating high school students' chemistry thinking method by using Thinking Maps in exercise teaching process and analyze its feasibility;Next,after combing the theoretical basis of cultivating high school students' chemical thinking in Thinking Maps.Students' learning activities with the help of the Thinking Maps can be divided into two aspects: constructing knowledge and analyzing exercises.Generate the corresponding using strategies of Thinking Maps for the two kinds of learning activities.Apply these two strategies to the teaching of exercises and conduct one semester of teaching practice.Show the teaching cases and analysis during the period;Finally,after teaching practice,check high school students' level of mastering chemical thinking method by using the Thinking Maps strategies through the experimental research method and the oral report method.And analyzes the students' thinking process from the report between the experimental class and the compared class.Conclusions:First: Thinking Maps strategies can help students take the initiative to build knowledge system.Students who use Thinking Maps strategies can actively look for logical links among chemical knowledge points and construct the chemical knowledge system effectively and actively,then deepening their understanding of the acquired knowledge.The structured knowledge system help students extract relevant information from cognitive structures efficiently when solving related chemical problems.Second: Thinking Maps strategies can help students take the initiative to build knowledge system.Eight graphs in Thinking Maps are based on eight thinking techniques which is used frequently.They represents eight different thinking method: Induction method,Deductive method,Classification method,Comparative method,Analogy method,Analytical method and so on.Combined with the strategies of chemistry,put the Thinking Maps into the teaching process of chemistry exercises and find out the link between the knowledge and the problem elements of the relationship in the form of graphics,in order to help students learn chemistry thinking method under the force of interest.Third: Thinking Maps strategies can be used as a tool for thinking migration.Thinking Maps can help improve students' ability to summarize,analogical migration,reasoning analysis and problem-solving skills.It can not only establish the connection between the chemical concepts in the cognitive structure of students,improve the efficiency and corrective rate of problem solving;but also can help students abstract the basis of the problem,so that students can take the initiative to sort out the idea of thinking,enhance students' self-confidence,and achieve efficient problem-solving ability.Therefore,Thinking Maps strategies have a certain value in the high school chemistry exercises teaching process of.It is expected that this paper will serve as the function of providing a footing stone for chemistry teacher in senior high school and apply Thinking Maps to actual teaching activities to for making high-effective classroom.
