Research On High School Chemistry Teaching Based On Micro-Course

With the development and popularization of interconnection technology and mobile terminal equipment,China has ushered in a new era.How to make education,the most important task of our country,benefit from this new era is inseparable from our constant exploration and research.In recent years,micro-blog,micro-message and micro-film have swept across the world.As a new type of educational resources,micro-lesson has been widely used in various fields.With the advent of "micro-lesson",our learning thinking has been changed subtly,and our learning methods have also been improved.Borrowing the wind power of "micro-era",the combination of micro-class teaching and high school chemistry teaching,with its novel teaching mode to stimulate students' interest in learning,its flexible use of ways to expand students' learning methods,has become the research direction of this topic.In the part of research review,the definition of the concept of micro-lesson is clarified,and its characteristics of short and concise,prominent theme and flexible use are elaborated.At the same time,it introduces the research status at home and abroad,and analyses the theoretical basis of the implementation of micro-course teaching.In the educational and teaching practice organized by the school,through long-term follow-up to the classroom,we understand the current situation of high school teaching mode;through reading a large number of reference books and literature,we grasp the characteristics of high school chemistry curriculum;through discussions and exchanges with front-line teachers and subject leaders,we clarify the key points,difficulties and test points of high school chemistry knowledge.The above preparatory research lays a certain foundation for the application of micro-course teaching in high school chemistry teaching.Under the call of the era of education informatization,based on school education and with the help of mixed teaching mode,this research integrates traditional teaching and Internet teaching,so that they can complement each other,and puts forward a new teaching mode of "classroom teaching + micro-teaching".Taking the topic knowledge of "organic compounds" in the third chapter of Chemistry 2 of senior high school as an example,this paper designs and constructs the micro-course teaching mode of senior high school chemistry.This paper puts forward the design principles of the teaching objectives and contents of micro-course,designs the framework of the subject knowledge of "organic compounds",provides the mode design for micro-course teaching videos,summarizes the development process of micro-course videos,and provides three kinds of micro-course teaching application modes for teachers according to different needs,including pre-class,in-class and after-class.According to the content characteristics of the subject knowledge of "organic compounds",the micro-course teaching videos are divided into four types: course introduction,knowledge explanation,experiment exploration and content expansion.Taking acetic acid as an example,which contains the above four types of module content,according to the micro-class teaching design mode and the microclass video development process,the micro-class video content design is carried out in detail,focusing on the preparation of micro-lesson plans and the writing of micro-scripts,in order to provide the first-line high school chemistry teachers with perceptual materials.
