Construction And Application Of Wechat Platform For Chemical Resources In The Teaching Of Science In Elementary Schools

In February 2017,the "primary Science Curriculum Standards"promulgated by the Ministry of Education requires that the "Science"curriculum be set up from the first grade.The new curriculum says that the use and development of scientific learning can promote the network of resources.In practice,the lack of systematic teaching resources for chemistry,especially in chemical experiments and elaborating the chemical principles.Taking advantage of the convenience of the Internet era,this study has built a chemical resource WeChat platform,which is synchronized with the The new curriculum and "Science" textbooks.The platform develops teaching resources related to chemistry,and strives to provide first-line teachers with a library of free chemistry teaching resources.This article focuses on the construction and application of the WeChat platform for chemical resources in primary school "science"teaching.The text focuses on the construction and application of the WeChat platform,including the construction of the platform framework and resource content,and the application of teaching practice.The platform framework includes the registration and maintenance of the WeChat public number;The content of the platform includes the topics,contents and forms of chemical resources;the application of the WeChat platform includes the resources download application and teaching practice.Through the analysis of the document literature,the status quo of the development and utilization of chemical resources and the concept of international science education are studied to determine the research direction of this article.Through the content analysis method,the texts such as "Elementary Science Curriculum Standards" and "Science"textbooks are analyzed,and five themes related to chemistry were selected for the primary school,including chemistry and life,material change,energy and environment,fascinating materials,air and water.The status quo of the development and application of scientific chemistry teaching resources in elementary schools was investigated through questionnaires,and the results of previous content analysis confirmed the chemistry theme,content and form of the resource,and choose to upload the developed resource to the WeChat public number platform for scientific teachers to download and apply.This article studies the case of applying the four forms of resources such as scientific drama,popular science video,hand-made,and chemical experiment in teaching.It combines the results of questionnaire surveys of platform users to analyze the effect of the resources developed in teaching and the utilization of resources.Draw the improvement strategy of platform construction and application.The survey found that the WeChat platform for chemical resources constructed in this article has provided the front-line science teachers with teaching aids in chemical experiment design and simplified chemical principles,and solved some practical problems in chemistry teaching.The WeChat platform provides free and practical teaching resources.These teaching resources can attract the attention of primary school students in teaching practice,stimulate students' interest in learning science,expand their horizons,and are well received by most science teachers.
