Research On The Teaching Practice Of Mind Mapping Teaching Method In The General Review Stage Of Electric Field

Students' ability to solve physics problems is an important embodiment of students' ability to understand and apply knowledge,and is also an important ability goal to cultivate in the general review stage of senior high school.In the face of the situation of physics problems,whether the students have established a stable cognitive structure and standardized and orderly problem-solving operations in their minds is just the external manifestation of the corresponding physical problem-solving ability.At present,senior high school students lack the ability to construct a systematic cognitive structure of electric field,especially the ability to effectively connect relevant knowledge and form problem-solving ideas according to the situation and state of the problem,and the ability to solve electric field problems is insufficient.Investigate its reason is historical field total review stage of the teaching mode and the high school stage,there is no essential difference between teachers not according to the characteristics of the electric field complex content abstract and logical sums up the general methods,unable to reach a basic stable electric field to help students build the cognitive structure of the teaching effect,as a direct result of the students' memory storage to fragmentation,widespread knowledge between hard knowledge mastery,thus the electric field in the process of problem solving,can not correctly identified,combing knowledge and application of electric field to establish logical answer the following questions thinking clear,related electric field problem solving ability is insufficient.The author through the literature review,under the guidance of relevant education,learning psychology,combining with the characteristics of mind map teaching techniques,to cultivate students' ability to build basic stable electric field cognitive structure and developing students' ability to solve field problem,put forward with "electric mind map teaching method" to guide students in specification steps for problem solving.This teaching method first guides students to construct the electric field mind map,then requires students to solve problems according to the orderly problem-solving steps of the mind map constructed by application,and insists on the implementation of the teaching links such as the integration of exercise resources,demonstration teaching,assignment,homework correction and revision.The aim is to encourage students to experience the process of constructing electric field cognitive structure,from being asked to solve problems in an orderly way by teachers,to accepting the steps of solving problems in an orderly way so as to form habits,and finally to internalize the autonomous consciousness and learning behavior of using physical knowledge rules to solve problems in an orderly way,and finally to achieve mastery among knowledge points.Two classes of the same level taught by the author are taken as the research objects to carry out educational experiments.By comparing the results of three academic measurements and analyzing the questionnaire results,the following conclusions are drawn:1.The teaching method of electric field mind mapping can teach students a general method to solve electric field problems,which is a specific and orderly operation mode to solve physical problems.This teaching method can effectively improve students' efficiency in solving electric field problems and build up their confidence in solving problems,significantly improve students' academic performance and obtain high recognition.2.This teaching method can effectively develop students' ability of using electric field cognitive structure to solve problems in an orderly manner.Through continuous experience,reflection and comprehension in the process of problem solving,the logical relationship between each cognitive node is clarified,and the students are encouraged to realize mastery among knowledge points.
