Research On The Design And Application Of Micro-lesson In Senior High Physics On The Basis Of Key Competencies

Under the background of new curriculum reform and IT in education and taking Kinematics as an example,this paper studies the design and application of micro-lesson in senior high physics on the basis of key competencies.In the design part of micro-lesson,this thesis shows three micro-lesson examples on the basis of key competencies.In the applied part of micro-lesson,by adopting the method of contrast experiment,studies the effect of micro-lesson on senior physics teaching.The experiment results show that the micro-lesson of mechanics can meet the individual learning needs of different students.Poor students can restudy physics to make up for the physical knowledge and methods they have not mastered in class.Excellent students can consolidate physics and build a physical knowledge structure system and improve their self-learning ability.It stimulates students' thirst for knowledge.Students can learn physics actively and become the master of learning.It deepens students' understanding of physical situation and improves their physical thinking ability.The process of physics teaching assisting with micro-lesson has become the process for students to improve the core quality of physics.This thesis includes the following five parts:The first chapter is the introduction.Firstly,this part introduces the background of the topic,then analyzes the status quo of micro-lesson and key competencies at home and abroad,and puts forward the credibility and necessity of combining micro-lesson and key competencies.The second chapter is a theoretical overview,which mainly describes the concepts and theoretical basis of micro-lesson and key competencies.The third chapter is the design part.This part analyses the curriculum objectives and curriculum content and learns situation analysis through the questionnaire survey.Basing on these analysis,this paper designs the micro-lesson by taking CS8 as a tool and shows three micro-lesson examples on the basis of key competencies,which are the micro-lesson of physical concept "overweight and weightlessness",the micro-lesson of physical law "conservation of mechanical energy" and the micro-lesson of physical experiment "explore the characteristics of flat throw motion"The fourth chapter is the application part.It conducts a comparative experiment in class 14 and class 18 in 2018 of Binhai middle school in Jiangsu province.Finally,the teaching effects are compared and analyzed by using the evaluation method of mechanical periodic test.The fifth chapter is the conclusion and prospect part.
