Research On The Optimization Strategy Of Physics Cognitive Structure Of High School Students

Physical cognitive structure reflects the storage state of physical knowledge in students' minds and the information processing mode of physical knowledge.This study makes a deep analysis of the physical cognitive structure of senior high school students,and measures the cognitive structure of key class students and ordinary class students respectively,and puts forward the teaching strategies of optimizing the cognitive structure for students of different class types.This study completed the following work:1.By looking up relevant theories at home and abroad,it is clear that cognitive structure can be divided into static cognitive structure and dynamic cognitive structure,in which static cognitive structure includes declarative knowledge,procedural knowledge and modal knowledge.Dynamic cognitive structure includes cognitive mapping,cognitive manipulation and cognitive monitoring.The characteristics of good physical cognitive structure are defined.The measuring methods of cognitive structure are sorted out.2.Through a qualitative analysis of the physical cognitive structure of senior high school students by means of questionnaires,it is found that there are significant differences between the cognitive structure of key class students and that of ordinary class students,and there is no significant difference between the cognitive structure of students of different genders.The cognitive structure of students is quantitatively analyzed by using the state attribute hierarchical graph.It is found that the static cognitive structure of students in ordinary classes is defective,and the degree of systematization is not high.It is manifested by the incomplete mastery of declarative knowledge and procedural knowledge,and the scattered dynamic cognitive structure.The students in key classes have strong static cognitive ability and perfect knowledge representation,but they lack cognitive operation and cognitive monitoring ability,which shows that they have not established a complete knowledge system for knowledge.3.According to the cognitive structure defects of students of different classes,specific teaching strategies are put forward.Ordinary classes should lay stress on consolidating the foundation and structuring declarative knowledge,teaching procedural knowledge and promoting the formalization of knowledge,grasping thecharacteristics of physics and cultivating students' cognitive mapping ability.Key classes should cultivate students' knowledge transfer ability,promote the construction of model knowledge,divert students' thinking,pay attention to the cultivation of cognitive operation ability,and promote the improvement of cognitive monitoring ability.4.Based on the proposed teaching strategy,the teaching design based on the optimization of students' cognitive structure is designed,and the practical research is carried out.It is found that the strategies based on the optimization of students' cognitive structure can effectively improve the students' academic performance.5.The conclusion,deficiency and prospect of this research are expounded.
