Research On The Cultivation And Practice Of Students' Physics Concept In High School Physics Teaching

With the development of the times,the social requirements for talents are also constantly developing in the 21 st century,the educational reform of all countries has begun to focus on the core quality,and China has also explicitly put forward this requirement in the curriculum standards.Physics as a basic subject,the cultivation of the core quality of physics plays an irreplaceable role in the growth of students and directly affects their whole life.The curriculum standards of high school physics issued in 2017 clearly pointed out training requirements of core physics literacy.The physics concept is an important part of the core quality of physics.so how to implement in the process of teaching to cultivate students' physics concept is also the physics teachers need to pay attention to the problem.Physics concept is based on the high generalization of physics concept's and laws,which is formed in the minds of students after deepening and can guide students' social life and work.Many scholars have discussed the theoretical research of physics concepts,but there are no practical cases.Therefore this paper tries to find a teaching model that can effectively construct physics concept based on practice.Based on the content of physics concept,this study defines the concept of physics concept on the basis of the research of relevant literature at home and abroad.At the same time,based on the theory of constructivism and cognitive learning theory as well as the theoretical research of related scholars,this paper puts forward a four-step teaching model of“factual experience--physical laws--core concepts physical--concepts”,and explores the teaching strategies under the background of this teaching model.In order to prove the feasibility of the teaching model,an experimental study was conducted in this study.Through experiment and comparison,the experimental class was carried out in this teaching mode,and the teaching practice was carried out for the part of“Law of Conservation of Mechanical Energy”.Finally,based on the SOLO Evaluation system,combined with the level division of physics concept in the high school physics curriculum standard,the level of students' energy concept is divided and tested.The practice results show that the four-step teaching model is feasible to construct the students' physics concept,and the students in this teaching mode show a higher level of energy concept.This study found that,based on this teaching model and combined with certain teaching strategies,to some extent,it can help students' better grasp the laws behind physical phenomena,further integrate and form core concepts,and finally form physics concepts during the transfer.
