The Study On Learning Progressions About The Concept Of Physical Energy In Middle School

The new curriculum standard emphasizes the importance of "physical concept" in the core quality of subjects,it is pointed out that the key to the understanding of "physical concept" is to grasp the abstraction and sublimation of physical concepts and laws in the mind,and "Energy concept" is an important part of physical concept,In order to make students form the concept of energy better,we should improve the teaching of the concept of energy and lay a foundation for students to form the concept of physics.In view of this,based on the advanced learning theory,this paper explores the thinking path of middle school students in learning "energy concept",helps students sort out scattered physical concepts and make students meet the requirements of curriculum standards,so as to cultivate students' core discipline literacy.This paper mainly introduces the process of building an effective learning-progressions framework of "energy concept",and the process of exploring the advanced level of students in learning "energy concept".The purpose of this study is to explore whether the current progressions level of students in learning "energy concept" meets the requirements of curriculum standards,and try to put forward the teaching suggestions of "energy concept" based on learning-progressions research.The research methods adopted in this paper are literature analysis and questionnaire survey.The first part elaborates the research background and significance,the research status at home and abroad,research design and methods.The second part elaborates the identification of the concepts of learning-progressions and energy,and the relevant theoretical basis.The third part analyses the requirements that students should meet in learning "energy concept" from the curriculum standards,combs the "energy concept" in detail with the middle school textbooks,On the basis of this,we can ascertain the level of energy and establish the learning-progressions framework of "energy concept" in line with the development of students' thinking.The fourth part develops the testing standard of "energy concept learning" according to the established progressions framework.Through questionnaire survey,it measures two representative middle schools in Yan'an City.Statistical measurement data and two-dimensional analysis of its accuracy rate-concentration degree,to determine the current progressions level of students' understanding of "energy concept",and it is compared with the learning-progressions framework of "energy concept" to determine whether the students have reached the target level.The fifth part is the teaching suggestion of energy concept based on the learningprogressions.The sixth part is research summary and reflection.
