A Preliminary Practical Study On Micro Class Of High School Physics

With the characteristics of "short","small","fine" and "lively",micro-class has quickly become a hot spot of education.Students can learn micro-lessons flexibly and freely according to their own time.The original intention of micro course application in teaching is not to lay emphasis on students’ mechanical mastery of knowledge,but to promote students to build a model of independent learning.At present,many provinces and cities are holding micro class competitions in full swing,and there are many micro classes about high school physics on the Internet.The author will carry out practical research on this problem.The research object of this paper is the second year students of two model high schools in guilin and liuzhou,guangxi.Students learn micro-lessons made by the author on We Chat platform.The content of micro-lessons is topic explanation and knowledge topic.Through the teaching practice of two demonstrative high schools,this paper studies the students’ independent learning by using micro-class,analyzes the reasons of the students’ lack of enthusiasm for independent learning by using micro-class,and USES the combination of sensor and magnetic field knowledge to improve the micro-class.The research methods are questionnaire survey,educational experiment and literature review.The research conclusions are as follows: students are not motivated enough to use micro-lessons for independent learning;Teachers’ authority will affect students’ independent learning through micro-lessons;"Rain classroom" is more suitable as a micro-course platform;The length of micro class should not exceed 5 minutes;At the end of the semester,students are more interested in the micro class that explains the topic type.When the learning atmosphere is relatively relaxed,the content of the micro class should be as interesting and novel as possible.
