Research On The Determination Of Difficulties And Breakthrough Strategies Of High School Physics Teaching Based On Core Accomplishment

In the context of core literacy,Chinese educators are committed to infiltrating core literacy into the education of various subjects.The new edition of the "general high school physics curriculum standards(2017 edition)" clearly points out the core accomplishment of physics that should be developed in high school physics.Physics is the most difficult subject for high school students and teachers because of its abstractness and wide range of contents.The reason why physics is difficult to learn is that there are many difficulties in physics teaching.The existence of these difficulties makes physics difficult for students to learn and difficult for teachers to teach.In order to cultivate students' core accomplishment,we must break through the difficult points in physics teaching and let students exqperience the fun of physics learning.Therefore,the author studies the determination and breakthrough strategies of difficult points in physics teaching,hoping to provide some references for the teaching work of high school physics teachers.In the process of writing this paper,the author mainly studied the following aspects:(1)Firstly,by analyzing the related concepts of core accomplishment at home and abroad and the related researches on difficult points in physics teaching in China,this paper summarizes the causes and breakthrough strategies of the previous researches on difficult points in physics teaching,and points out the reference significance of the previous researches and the contents to be further studied systematically.(2)Difficulties in physics teaching are defined and classified according to the characteristics of physics.The difficulties in physics teaching are divided into thinking difficulties,application difficulties and resource difficulties.Combined with the characteristics of the subject,the relationship between the teaching difficulties and the teaching emphasis is sorted out.(3)Combining with concrete examples,this paper summarizes the factors that should be considered in the difficult points of physics teaching,which are the main body of learning-student factor,learning content--teaching material factor,learning dominant--teacher factor,learning conditions--environment factor and learning evaluation--examination system.Based on the above analysis,this paper puts forward the basis for determining teaching difficulties,which are the influencing factors of teaching difficulties,the content requirements of curriculum standards and the core accomplishment of physics.(4)Combined with teaching practice and specific cases,this paper proposes some strategies to break through teaching difficulties,including setting up scenario method,using computer software to assist teaching method,introducing physics history method and changing evaluation strategy method.(5)Taking "flat toss" as an example,this paper analyzes the determination process of teaching difficulties based on core literacy and the breakthrough strategy of difficulties based on core literacy.Through the research,it is found that the teaching breakthrough program based on difficulties can not only improve the students' physical performance,but also the student-centered design program can improve the students' sense of effectiveness in class and cultivate their core qualities in physics.
