Research On Core Concept Of Electromagnetic And Instructional Design In Senior High School Physics Teaching

With the international community on the core concept of universal concern,the core concept of teaching has become a trend.The physical core concept refers to the physical knowledge which can be widely applied,including the concept,the law and the principle.The physical core concept always leads each physical principle and the establishment of the law,is the key to learn physics.Based on the theoretical basis of the core concept and the standard of Chinese and American curriculum,this paper analyzes the concept of high school physics electromagnetic core by analyzing the content analysis method,the questionnaire survey method and the action research method,and analyzes and studies the teaching of the core concepts at home and abroad,Try to build a core concept as the center of the instructional design framework,the preparation of teaching cases and applied to practice,for the first-line physics teachers to provide practical operational methods.This topic is divided into six chapters,the main contents are as follows:The first chapter is the introduction.This paper mainly discusses the background of the research on the core concept,the definition of related concepts,the research history and current situation of core concepts and instructional design both at home and abroad,as well as the main contents,significance and methods of this research.The second chapter is the theoretical basis of the study.On the basis of the three theories of constructivism teaching theory,meaningful learning theory and Gagne’s instructional design theory,this paper expounds the main contents of the theoretical basis and the enlightenment of the theoretical foundation on the core design.The third chapter is the definition of the core concept of electromagnetic physics in senior high school.First of all,from the American science curriculum standards and national standards of ordinary high school physics curriculum,to determine the screening standard of core concept of our high school physics electromagnetic;and then comb about the electromagnetic concept of each chapter version under the high school physics teaching material,to tease out the 82 electromagnetic concepts,comparison with the high school physics curriculum standards and the core concept of screening standards,after refining the final focus on the concept of 28: Finally,through the teacher questionnaire survey,the final high school physical electromagnetic core concept a total of five,respectively: closed circuit Ohm’s law,Faraday’s law of electromagnetic induction,electric field intensity,Lenz’s law,magnetic induction intensity.The fourth chapter is the core concept as the center of the instructional design.The core design of the core concept is based on the analysis of the contents of the teaching materials,to determine the core concept,through the arrangement of teaching process,select the teaching strategy to build the core concept to evaluate the learning results to continuously improve the instructional design process.Through the research on the instructional design model of experts and scholars,this paper puts forward a framework of instructional design to the core concept as the center,including screening the core concept,analyzing the teaching content,determining the teaching goal,arranging the teaching process,selecting the teaching strategy,evaluating the learning result,constructing the core concept,and discusses the contents of each link,finally according to the core concept of instructional design framework design "electric field intensity" instructional design case.The fifth chapter is based on the core concept of instructional design practice.The preparation of a good "electric field intensity" instructional design case applied to practice,through monthly exam papers and analysis of exercises,the results show that the core concept of teaching can promote the students to understand and grasp the concept,teachers should strengthen the core concept of the importance of teaching.The sixth chapter is conclusion and reflection.Sum up the conclusions and shortcomings of this topic,hope that the future researchers can continue to study in this area in-depth,put forward a more complete core concept as the center of the instructional design framework.
