| The concept of teaching is one of the basic and core task of physics teaching.The students’ mastery of physical concepts and decided to use his understanding of the laws of physics,so we must pay attention to the concept of teaching.The core concept is the main subject in knowledge center,has the important role to other concepts,according to the definition of data access arrangement the establishment of the core concept,the core concept is that establishing backbone knowledge structure of discipline necessary,are important concepts of interpretation and extension of function,principle and theory.There are more and more researches in recent years on the core concept,the core concept becomes a hot topic in today’s education.The high school physics curriculum is an important part of high school science education,plays an important role in cultivating students’ scientific literacy,the electrical part of the concept of more and are more abstract,before the students lack of knowledge of perceptual knowledge accumulation,lack of the concept makes it difficult for the students to learn,so the study of electrical core concept part of the senior middle school physics and teaching strategies is of great significance for the high school physics teaching.This research mainly conducts the research from the following four aspects: first,the high school physics curriculum standard,analysis of senior high school physics textbooks in the field of knowledge,through the analysis of the specific teaching content,determine the core concept of electricity.Second,the selected electrical knowledge is compiled into a teacher questionnaire and through the questionnaire to the teachers,make teachers according to their own understanding of the importance of the concept of judgment,as an important basis to determine the core concept of electricity.Third,analysis of nearly three years of college entrance examination of physics in electrical part of the test,find the concept of knowledge college entrance examination focuses on the three part of the above analysis and discussion,and ultimately determine the electrical part of the core concepts of physics in senior high school.Fourth,put forward the core concept of teaching suggestions,in the hope of the core concept of high school physics teaching has certain inspired.Through the above research,this paper obtained the following conclusions: first,through combing teaching and research,and ultimately determine the core concepts for electrical physics of electrostatic field,electric field strength,electric field force,electromotive force,electromagnetic induction,electric potential,Ampere force,alternating current and closed circuit.Second,put forward three suggestions about the core concept of teaching that is,to establish the core concept of teaching ideas;creating situations to introduce the core concept of teaching;focus on the core concept of teaching content. |
