Case Study Of Physics Concept Teaching In Senior Middle School Under The Perspective Of Core

The promulgation of the new physics curriculum standard in 2017 provides a clear direction for teaching,and the educational goal is transformed from the original "three-dimensional goal" to "core quality".This change is based on the successful experience of foreign education reform and the basic national conditions of China at the present stage,aiming to cultivate a person who can adapt to new era of all-round development.Physics concept is the cornerstone of physics,physics concept runs through the whole process of physics learning,so this paper uses the method of lesson study to train students' core literacy in concept teaching.This paper adopts literature survey,questionnaire survey and interview method to provide a practical plan for cultivating students' core quality in concept teaching.This paper mainly consists of five parts:The first part is the introduction,which describes the background and present situation of the research,and clarifies the purpose and significance of the research.By combing the relevant literature,we understand the current situation of the study on the teaching of high school physics concept under the core literacy,and summarize the relevant research methods.The second part defines the concepts of core literacy,core literacy of physics discipline,concept teaching and curriculum study,and expounds constructivism theory,lifelong learning theory,curriculum standards of high school physics and related theories and curriculum standards of the subject,which lays a theoretical foundation for the curriculum study.In the third part,according to the requirements of the new curriculum standards and the results of literature research,the questionnaire of students and the interview outline of teachers are designed to understand the cultivation of core literacy in high school physics concept teaching.In the fourth part,"Acceleration" and "Elasticity" are selected to design the teaching design to cultivate the students' core quality of the subject,and carry out the teaching.According to the results of classroom teaching evaluation and exercise case analysis,the two lesson cases are optimized,and the concrete implementation steps and general methods of cultivating students' core quality of physics subject by using lesson case study in concept teaching are obtained.The fifth part is the research result,reflection and prospect.Through this research,the conclusions are as follows: first,it is possible to explore how to cultivate students' core literacy by means of lesson case study;Secondly,the cultivation of students' core qualities and the obstacles in the training process are clarified.Third,with the help of two conceptual classes,the general steps and methods of training students' core literacy of the subject are formed.At the same time,it reflects on the shortcomings of this study,and it is necessary to expand the scope of education investigation in the future research to understand the different needs of students of different levels.It is expected that the conclusions of this study can be applied to regular classes.The innovation and shining points of this paper are mainly reflected in the following aspects: the lesson case study provides a paradigm for promoting teachers' professional development and optimizing teaching,and this study takes it as a way to cultivate students' core literacy;Based on the questionnaire survey and interview,the paper summarizes the existing problems of cultivating students' core quality in teaching.The general steps and methods of cultivating students' core quality in concept teaching are determined by selecting two concept classes for in-depth study.
