Feasibility Study On The Teaching Of Science Micro-teaching In The Lower Grades Of Elementary School Based On WeChat Public Platform

As mobile internet is coming forth,and following intelligent hardware such as tablet PCs and smart phones is widespread among the public,people consider ?life on palm? as more necessary part.Now,WeChat public platform,a new promotional vehicle for socializing,accepted by more and more people,plays a significant role in entertainment and information collection,which opens a new chapter for ?mobile learning?.Now,the public tend to learn in piece with the aid of WeChat platform,and micro-course,characterized as short,small,extract and flexible,is more beneficial for spreading mobile internet.According to the literature searching and theoretical studying,this dissertation,on the basis of science and technology teaching for lower elementary school students on the WeChat public platform,combines analysis of elementary school students? cognitive abilities,psychological characteristics and existing knowledge structure with the feature of the second grade?s science and technology.Accordingly this article sorts out the knowledge emphasis into diverse modules,and designs teaching contents and teaching objectives flexibly,aiming at helping students with mastering scientific knowledge and improving their interest in learning.Micro-courses designed by the matching idea will be pushed to the subscribers(including students and parents)by the mean of WeChat platform.At the end of a semester-duration micro-course,in order to examine the variation of studying effect among students,statistical analysis is developed on the pretest and posttest data of the experimental group and the control group.In addition,the information regarding instructors,parents and students is collected by means of questionnaire and interview survey.In this basis,the author thoroughly analyzes the possibility of micro-courses(science and technology)for the lower elementary school students.The study shows:(1)The method of micro-courses on the WeChat public platform inspires the interest,improves the learning achievement and enhances the motivation of learning science.(2)The implementation of the curriculum enhances the students' desire to explore the scientific phenomenon and enhances their curiosity about the surrounding scientific objects.(3)By learning the course,students could handle with WeChat public platform independently,and operating skills of information technology are apparently increased.(4)From the feedback of parents,learning interest and thirst for knowledge have been promoted,they commonly think the new learning method beneficial for mastering scientific knowledge.(5)The production and management of online micro-course consumes much time and energy,which impedes the front-line teachers? initiative of micro-course implement.Besides,this paper summarizes the advantages and disadvantages of the micro-courses(science and technology)for lower elementary school students,and in this new teaching mode,teachers,parents and students? role have been changed consequently.In the end,the article puts forward the direction of further research.
