The Study Of The Unit Teaching Design Based On Micro-lesson

With the continuous advancement of curriculum reform in China,the school has put forward higher requirements for the teaching of teachers.According to this kind of situation,this paper takes the electrostatic field of the teaching material of high school physics 3-1 as the unit teaching design topic,carries on systematic teaching design,and uses the screen recording software and the master of colorful animation making the micro-lecture of the teaching design.The author used the internship opportunity in the school to apply micro-lectures in teaching,so as to study the application effect of micro-lecture in practical teaching.By studying the relevant literatures,The author find that the micro-lecture is mainly carried by video,and expand around a small knowledge point or teaching link,It has the characteristics of short time and concise content.The main types of micro-lecture are lecturing type,solution type and experimental type.This paper studies the design forms of micro-lecture in depth,and designs two kinds of micro-lectures: one is to use the screen recording software,PPT and the recording software;the other is made by the master of colorful animation and the recording software.This paper introduces the manufacture method of making the two micro-lectures above in detail,after comparing the characteristics of these two kinds of production methods,has concluded that the method using the screen recording software operating is more simple,more suitable for making micro-lecture of the simple conceptual knowledge;Although the production of the micro-lesson by the master of colorful animation is slightly complicated,the micro-lecture produced is more effective,which is more suitable for the making of the micro-lecture of the difficult knowledge.During the teaching design of electrostatic field,combined with the characteristics of the micro-lecture,the author made in-depth analysis about the key points and difficulties in the teaching material content.Through the analysis,the author found that the emphasis in the electrostatic field is the electric field intensity,electric field lines,electric potential difference,equipotential surface and so on;The difficulty is the relationship between electric field force’s work and potential energy as well as the movement of charged particles in an electric field.Therefore,the micro-lecture inserted in teaching design mainly involves the key points and difficulties in electrostatic field.The author applies the unit teaching design containing micro-lecture in high school physics teaching,through the experiment and the interview knowing that micro-lecture was applied to the teaching of the electrostatic field,on the one hand,it’s good to improve the learning interest of students,and to change the plight of teachers’ teaching difficult;On the other hand,teachers’ ability and time have also became the factors that influence micro-lecture teaching.In a word,both students and teachers have great expectations for micro-lecture,and hope to develop more suitable micro-lectures for teaching in the future.
