Research On Teaching Strategy Of Physics Energy View In Senior Two Based On Advanced Learning

Physics Curriculum Standards for Ordinary Senior High Schools(2017 edition)puts forward the concept of physics as the first core accomplishment.Physics concept is the premise of implementing physics core literacy teaching,and energy concept is one of the important components of physics concept.The formation of energy is the refinement and sublimation of the complex and scattered knowledge in the human brain.Learning advancement is the advancement of students’ learning process and the process of guiding teaching to reach the final level step by step.The construction of quantity pays attention to the internal logic of knowledge itself and the formation process of knowledge,while advanced learning can integrate the concept of energy and deepen and systematize the complicated knowledge of energy.As a current research hotspot,the study of advanced learning is still relatively little in the view of physical energy.Therefore,this paper takes the energy view of senior two physics as the research object,tries to establish the advanced level of energy view of senior two physics by investigating the cognitive level of energy view of senior two students and analyzing the current teaching situation of energy view of teachers,and puts forward the corresponding teaching strategies,providing reference for the teaching practice of energy view.The main research is as follows:Firstly,theoretical research.Through literature research,the research status of energy concept and advanced learning is summarized,and the concepts and connotations of "energy concept" and "advanced learning" are determined.Then,sort out and analyze the energy knowledge in the curriculum standards and textbooks,and provide support for the specific energy knowledge needed for the preparation of the questionnaire questions.At the same time,the evaluation of students’ cognitive level of energy view needs specific theoretical basis and standards.Then,guided by the division of human cognitive level in Marzano’s taxonomy of educational objectives,the four dimensions of students’ energy view construction,namely,the four dimensions of energy form view,transfer and transformation view,conservation view and dissipation view,are respectively divided into four levels: extraction level,understanding level,analysis level and knowledge application level,that is,the determination of four dimensions and four levels.Then,investigate and study.Through the questionnaire survey,we know the cognitive level of senior two students’ energy view,and analyze the questionnaire data with SPSS data analysis software,and then get the following conclusions: the cognitive development level of students’ energy view is in the transition stage from understanding to analysis,and the cognitive development level of dissipative view is in the transition stage from extraction to understanding.Through the analysis of the teaching fragments of teachers’ new courses and exercises,it is concluded that the present situation of teachers’ energy view teaching is as follows: some teachers have advanced ideas in teaching,but they don’t deeply realize the gradual development of ideas,and they intend to wait for enough energy knowledge to accumulate before summarizing the energy conservation ideas,and they are not deep enough and multi-angle in explaining the energy knowledge and laws.Then,the principles of establishing and cultivating the advanced level of physical energy concept in Senior Two are carried out.Through the investigation of the current situation of students’ cognitive development level,the current level of students’ energy view is taken as the starting point of students’ advanced energy view,the ultimate goal of the concept-solving practical problems in life is taken as the advanced end point,and Marzano’s division of people’s cognitive development is taken as the advanced intermediate level,thus establishing the advanced level of energy view: understanding level,analysis level,knowledge application level and practical problem solving level.According to the establishment of advanced level,the following training principles are put forward:(1)the principle of gradual and orderly progress,(2)Life principle,(3)systematic principle.Finally,through the above research,the following teaching strategies are put forward:(1)Mining energy facts and perceiving energy knowledge;(2)Set up advanced questions and understand energy knowledge;(3)Solving practical problems and establishing the concept of energy;(4)Improve the concept of energy with the help of mind mapping.
