Research On Instructional Design In The Elaborative Processing Stage Of Physical Concepts And Laws ——Based On The Perspective Of Cognitive Psychology

The concept of physics is gradually formed on the basis of students' real understanding and application of physical concepts and laws.To truly understand physical concepts and laws,we should not only remember the formula rules of concepts and laws,but also have an in-depth understanding of the connotation of concepts and laws.Therefore,in the teaching of physical concepts and laws,teachers should not only help students master the application rules,but also help students deeply understand the meaning and nature.In order to realize the understanding of the connotation of physical concepts and laws,students need to have a deep understanding of the connotation of the concepts and laws they have learned.Cognitive psychology can analyze the internal mechanism of learning and provide theoretical basis and support for the design and development of teaching activities in line with students' learning mechanism.Therefore,cognitive psychology can provide a certain direction for "the teaching and research of the elaborative processing of physical concepts and laws".The works are as follows:1.According to Bloom's taxonomy of educational objectives,analyze students' internal psychological process and external behavior when understanding the connotation of physical concepts and laws.2.Analyze and determine the learning results of the connotation of physical concepts and laws.3.According to the elaborative processing theory and the current teaching situation,this paper studies the essence of the profound teaching of the connotation of physics concepts and laws,and puts forward the corresponding design mode of the elaborative processing teaching.4.Develop specific teaching plans according to the elaborative processing teaching design mode,and conduct teaching implementation and effect research.The research methods are: questionnaire survey,literature research and experiment.The conclusions are as follows:1.When students understand physical concepts and laws,the internal representation form is concept and law schema,which can show the behavior of explanation,example,distinction,generalization,explanation,inference and comparison;When students can apply physical concepts and laws,their internal representation is production and production system,and they can show "execution" and "implementation" behavior externally.2.The learning result of the connotation of physical concepts and laws is the connotation schema of physical concepts and laws,including physical meaning and physical properties.Physical properties include expression rules,physical quantity size,relationship between directions,sub concepts,etc.3.The essence of elaborative processing teaching of physical concepts and laws is: after students have a preliminary understanding of the rules and properties of physical concepts and laws,let students understand the significance and properties of physical concepts and laws from the object,process and the relationship between physical quantities through multiple situations.4.Based on the theoretical and practical results,the teaching scheme of physics concepts and laws at the intensive stage is feasible,and can effectively promote students' understanding of the connotation of physics concepts and laws.
