Practice Research Of Improving Mathematics Teachers' Professional Basing On "Bi-Micro" Mode

The purpose of this study is to explore an effective and feasible teaching mode to help the pre-service teachers(primary school students)and the primary teachers to adapt to the front-line teaching and improve their professional skills.Therefore,this study uses a combination of literature research,action research,quantitative research of these three methods.In the course of literature research,the external features of "Micro-teaching" and "Micro-course" in the CNKI general library are first summarized by bibliometrics.Then we construct the co-word matrix to complete the analysis of the internal structure of micro-teaching and micro-course.Action research phase to complete the three tasks.First,using micro-Kingship Po equipment,Camtasia Studio video recording,editing software,IMindMap concept map software,to make micro-class video.Second,renamed this videos by using RenamePro8 batch,and then released those videos to Youku?YouTube,what's more,by using We-chat public number to push and micro-course content to collect production-related information.Thirdly,through the data statistics function of the media platform,the data indicators,such as the number of times the micro-screen,is displayed and the audience's comments are obtained.In the third step,Firstly,expert interviews and related literature,generally clear about the evaluation of high school micro-teaching direction and dimensions.Secondly,based on AHP,the weight of each evaluation index of high school mathematics micro course was established.Five secondary teachers were invited to use the fuzzy comprehensive evaluation of the production of 192 micro-video in the 10 samples of the evaluation score.Finally,compared the scores of teachers with the specific sample content of the interpretation of the lessons and learned from the relevant experience to make a conclusion.
