Research On Core Concept Learning Progressions Of Middle School Physics Based On Deep Learning

Physical concept is the reflection of the common physical attributes and essential characteristics of the objective things in people's mind,is an abstraction of the objective things,and it is the core component of the content of physics in middle school.In middle school physics teaching,it has been an important goal and task for middle school physics teaching to make students form,understand and master physics concepts,and then develop the core quality of physics subject.At the same time,it has been a difficulty and weakness in middle school physics teaching.Based on the theory of deep learning,this paper selects three typical core concepts in middle school physics teaching.From the perspective of students' cognition,it adopts the way of advanced learning to explore the formation and development process of middle school students' physical concepts,so as to realize the understanding and mastery of physical concepts.The core of advanced learning research is to define and deconstruct the core concepts,to explore the cognitive structure of students' physical core concepts,and to presuppose the advancement of concepts.The theory of deep learning emphasizes the design of learning activities,the sustainable development of students and the depth and essence of knowledge,which can provide a way for the presupposition of concept level.This paper mainly consists of three parts.Firstly,summarizes the guiding ideology of the deep learning theory,constructs the advanced path of the physical concept in the framework of the advanced learning model,aiming at the formation process of the physical concept;Secondly,combs the curriculum requirements and the physical textbooks of the junior and senior high schools,determines the core concepts of the middle school physics based on certain selection criteria,and selects the core concepts of the middle school physics.Taking the concepts of work,acceleration and density as the research objects,the paper analyzes the important knowledge points of physical concepts,draws the mind map,investigates the thinking obstacles of students' cognitive concepts,analyzes students' factual experience and knowledge reserve,and presupposes to advance to the next level;Thirdly,develop the case teaching of the core concepts of physics in middle school.In view of the advancement of the core concepts of physics,we should create situations to unify the starting point of advancement,design student activities,setup problems,help students overcome thinking obstacles,break through difficulties,carry out teaching evaluation,and make “concept cognition evaluation volume” to evaluate the achievements of advancement.This paper studies and selects the typical core concepts of middle school physics,presupposes advanced level,unifies the starting point of advanced level,selects advanced path,designs teaching activities,develops case teaching,and makes assessment tools for advanced concept learning.It is hoped that it can provide reference for the teaching practice of physical concept of physics teachers in front-line middle schools,explore the cognitive structure of physical concept of students,help students to establish physical concept,develop thinking ability,promote the learning of physical subject,and then develop the core quality of physical subject.
