Research On Creating The Teaching Situations Of Mechanics In High School Physics Based On Physical Concepts Accomplishment

Creating the teaching situations is to create and design situations with teaching and education functions.Creating the teaching situations with the goal of physical concepts is the requirement of key accomplishments.Mechanics is the beginning and foundation of learning physics in senior high school,so choosing to study how to create the teaching situations to improve students' physical concepts accomplishment level in the content of mechanics.Through literature research methods,the study elaborates the relevant concepts and the relation between creating situations and physical concepts accomplishment.Through situational teaching theory,situational learning theory and constructivism theory,the study analyses existing problems of creating the current teaching situations and the problems of creating situations in the three situational teaching modes from the perspective of cultivating the physical concepts accomplishment.After this,the principles of creating the teaching situations used in the new mechanics knowledge course and exercises course are put forward based on the theories and problems.Finally,the strategies and examples of creating situations based on physical concepts accomplishment are put forward according to these principles.The main results of this study are as follows: Firstly,the study examines four major problems in creating the teaching situations from the perspective of physical concepts through literature research methods,which is fussiness of expression,lack of continuity,rigor and emphasis on authenticity.Secondly,the study analyzed the problem of creating situations in PBL teaching mode,5E teaching mode and suggestive teaching mode,and found that:(1)creating situations in PBL teaching mode is too single,and requires students have certain knowledge and problem-solving ability,which is not conducive to the cultivating physical concepts accomplishment;(2)creating situation in 5E teaching mode is not applicable to all concepts,and it is difficult to distinguish and develop students in five stages;(3)It implies that creating situations in teaching mode requires too many teachers` abilitiesand emphasizes that the creation of artistic means which is limited by the characteristics of physics.Thirdly,combining these problems with the theories,the study puts forward the principles of similarity,generality,inquiry and stage for creating teaching situations in the new knowledge course of mechanics,and puts forward the principles of connection,continuity and innovation for creating the teaching situations in the exercise course of mechanics.Finally,under the guidance of these principles,proposing strategies of three stages of creating situations in new knowledge courses,as well as the strategies of creating continuous and progressive teaching situations in exercises classes and solving problems in complex situations by creating the simple teaching situations,and gives examples.
