Discussion On The Teaching Of Special Theory Of Relativity In The Compulsory Stage Of High School

"General High School Physics Curriculum Standards(2017 Edition)" has been condensed through more than ten years of general high school physics curriculum reform.Compared with the 2003 experimental curriculum standards,the2017 version of the curriculum standards is more instructive.The 2017 edition of the curriculum standards changed the special theory of relativity from high school physics elective content to compulsory content.In order to respond to the changes in the curriculum standards,this article conducts teaching exploration on the special relativity of high school physics under the compulsory situation.The first chapter of this article contains the content of the topic,the significance of the research,etc;the second chapter designs a questionnaire to understand the understanding of the first-line high school physics teachers on the special relativity teaching in the compulsory phase;Chapter 3 compares and analyzes the special theory of relativity in the 2017 version of the curriculum standard and the 2003 experimental version of the standard,recognizing the new requirements of the "core literacy" concept for teachers and students,and combining the principles of pedagogy to analyze the educational function of special relativity.At the same time,the current experimental version of the high school physics textbooks and foreign science books in the special theory of relativity are analyzed to extract teaching materials that meet the requirements of the 2017 version of the curriculum standards.Chapter 4 designs the teaching links of "preparation","teaching","learning" and "evaluation" of special theory of relativity in high school physics."Preparation" is reflected in the preparation of teaching hours,teaching objectives and teaching strategies.It has designed four core literacy teaching objectives,such as physical concepts,and has selected an ideal experiment model suitable for the compulsory stage of teaching,providing a compulsory teaching idea."Teaching " And "learn" focus on teacher activities and student activities in instructional design."evaluation" is mainly to refine the level ofachievement of the four dimensions of physics concepts in the teaching of special relativity,so as to teach students in accordance with their aptitudes and clarify the purpose of training.Through two instructional designs,the "teaching" and "learning" in the teaching link are explained in detail.The first instructional design combines the contents of the "two basic assumptions" and "mass-energy relationship" required by the college entrance examination syllabus to grasp the key points of the examination site.The second instructional design implements the 2017 version of the curriculum standard requirements of "Preliminary Understanding of the Theory of Relativity Time and Space",designs teaching activities with the theme of "time delay effect",and focuses on the use of "ideal experiments" to cultivate students' scientific inquiry ability and scientific thinking ability.
