Practical Research On The Teaching Of High School Physics Model Under The New Curriculum Standard

Since the promulgation of the General Senior High School Physics Curriculum Standards in 2017,the discussion based on the physics core literacy of the disciplines is in full swing.The physics core literacy of the disciplines is not only the shift of the focus of phys-ics teac hing from "heavy knowledge" to "heavy ability",but also a new test for the majority of fron tline teachers:how to implement physics core literacy in teaching,which makes some physic s teaching theories naturally flock to the core literacy vane.From the content of the new cur riculum standards,in addition to "the core literacy",the "model" is the most talked about in the standard,This is enough to illustrate the importance of physical models in the new curric ulum standards.From the perspective of the history of physics,physical models have contribu ted to the advancement of scientific research.In view of the current teaching,the ability of s tudents to construct models is insufficient,resulting in poor students' ability to solve practical problems.Therefore,in view of the above considerations,in order to implement the core lit eracy of the physics discipline and improve students' ability to analyze and solve problems,I n middle school physics teaching,it is extremely necessary to carry out physical model teachi ng.This article is based on relevant literature,discussed the classification of physical models for the convenience of practical teaching,The objectives and principles of physical model tea ching under the perspective of core literacy and How to understand the meaning of student p hysical modeling within the scope of high school physics knowledge.Combine some related r esearch,According to the requirements of "model construction" in the new physics curriculum standards,combined with the classification of Bloom's educational goals,Developed a student's physical modeling ability level performance table.Based on this table,Conduct a survey on the physical modeling ability of high school stu-dents.After analyzing the causes ofthe inves tigation,Put forward the strategy of carrying out model teaching in the three aspects of "new class teaching","workbook teaching" and "student practice".Especially in the teaching stag e of the problem class,Referring to Professor Liao Boqin's physics representation level,Combi nethe advantages of the physical model itself,Proposed a hierarchy of physicalproblem represe ntations of "characterrepresentation-modelrepresentation-modelintegration-mathematical representat ion".Improve students' ability to comprehensively use physical models.Finally,the teaching practice is guided by the physical model teaching strategy.The res ults show that physical model teaching can help improve students' ability to score,analyze an d solve problems.
