Teaching Video Analysis And Countermeasure Research On High School Physics Concept For Students Scientific Thinking Training

The Ministry of Education's "General High School Physics Curriculum Standards(2017 Edition)" clearly stated: "Physics core literacy" is an important manifestation of the value of physics education,and an important part of students' core literacy.Scientific thinking is one of the core elements of the core literacy of physics,and physics concepts are also one of the core contents of physics knowledge.The teaching process contains many elements of scientific thinking.Therefore,based on the "two cores",it is necessary to conduct research on the cultivation of students' scientific thinking in high school physics concept teaching.This paper analyzes the video of classroom teaching of high school physics concepts to find out the existing problems,and extracts the countermeasures for teaching high school physics concepts for students to cultivate their scientific thinking.Firstly,based on the "General High School Physics Curriculum Standards(2017 Edition)",analyze the connotation of the four elements of scientific thinking,and expound the relevant knowledge of physics concept teaching.Secondly,choose five high school physics concept teaching topics: "speed","acceleration","elasticity","friction" and "overweight and weightlessness" as observation examples,focusing on the four elements of scientific thinking and combining physics Educational teaching theory,it is constructed that a high school physics concept teaching course analysis analysis observation scale,and then using Nvivo11 software to teach high school physics concept teaching famous teachers and regular classes video and physics concept teaching regular classes of teachers of different ages.The statistical analysis is based on the time distribution ratio of the second-level indicators of scientific thinking.The study found that the average time distribution ratios for the training of "model construction","scientific reasoning","scientific reasoning" and "questioning innovation" in famous teachers' classrooms were 10.58%,48.58%,7.41% and6.69%,respectively,while in regular classes The average time distribution ratios in the schools are 4.31%,40.27%,6.21%,and 2.54%,respectively,indicating that the famous teacher courses in the teaching of high school physics concepts pay more attention to the cultivation of students' scientific thinking;both the famous teacher courses and the regular classes pay more attention to the cultivation of students' scientific reasoning Ability;In addition,in the regular class,teachers are lacking in model construction,scientific argumentation,and questioning innovation;in addition,it is found that older teachers will pay more attention to the cultivation of students' scientific thinking.Finally,based on the analysis of high school physics concept teaching videos,the teaching countermeasures for each teaching stage of high school physics concept teaching oriented to students' scientific thinking cultivation are extracted.Cultivate at the introduction stage of concepts,introduce new concepts by reviewing,create situations using students' familiar daily life phenomena,create situationswith real experimental phenomena,introduce concepts using the history of physics or historical stories,introduce new concepts by analogy And other teaching strategies to cultivate students' scientific thinking.In the stage of concept formation,teaching strategies such as emphasizing students 'experience and active participation,experiencing the process of constructing concepts,carefully designing students' experimental exploration activities,and carefully organizing students' exchange and discussion activities can be adopted to cultivate students' scientific thinking.In the concept understanding stage,you can adopt basic contents such as the definition of the concept,grasp the keyword sentences that reveal the essential attributes of the concept,pay attention to the in-depth analysis between the concepts,use teaching strategies such as mind maps and self-evaluation,and cultivate student science thinking.In the stage of applying and deepening concepts,we can adopt teaching strategies such as basic practice and summary reflection,creating real situations and experimental application concepts,setting open research or technology production,using modern science and technology or examples of life,to cultivate students' scientific thinking.These teaching strategies for each teaching stage of high school physics concept teaching for students' scientific thinking training will help to improve students' scientific thinking literacy in high school physics concept teaching,and provide teachers with high school physics concept classroom teaching for students' scientific thinking ability training.Provide guidance for design and implementation.
