A Study On The Teaching Practice Of Micro-class Applied To Junior Middle School Chemistry

With the coming of the Internet era,having a mobile terminal is normal.The way of learning by watching the microcourse becomes more and more popular.Teaching of chemistry is very tight and the teaching task is so heavy.Especially the concept of the chemistry is various and abstract.In order to teach more efficiently and break through the problems on teaching content.We must use micro teaching,which is terse and forceful.And make it combine with other teaching methods to optimize the classroom teaching.What’s more,micro teaching can make learners get teaching aims directly and improve their learning efficiently.Based on the theory of constructivism,mixed learning,autonomous learning and so on,this study comes to solve the teaching problems of jonior high through micro-traching.The method is literature review.First,I do some questionnaire survey on the local middle school students to fix the feasibility of the study and identify the problems in chemistry.Then,for each problem,do and develop each related micro-teaching and teaching design.And put them into practice before class,in class and after class.In the end,by questionnaire survey,interview and the comparation of final examination results,I make the conclusion that micro-class can be used to solve problems in junior high’s chemistry teaching.After one-semester practice,it was confirmed that micro teaching in middle school chemistry teaching is enforceable when it applies to knotty problems on middle school chemistry.On the one hand,it provides practical experience support for researchers who continue to research.On the other hand,the research can produce a great deal of high qualified syber source about middle school chemistry.In the further teaching,people can put it into practical teachings and it will be improved and perfected continually.
