Application Research Of Flipped Classroom Based On Micro-classes In The Teaching Of Chemical Elements And Their Compounds In Senior High Schools

The knowledge of "elements and their compounds" is not only the key but also the difficult point in high school chemistry learning.This research mainly adopts the methods of literature research,questionnaire survey,practice research and interview.Based on the theories of mixed learning,cognitive load,mastery of learning and ubiquitous learning,this paper puts forward the flip classroom teaching mode based on micro-lessons on the basis of previous studies.This paper expounds the general methods of making micro-class from the determination of recording mode,the choice of development tools,the making and synthesis of micro-classes,the testing and publishing of video,and designs the flipping classroom teaching activities based on micro-class from the three links of pre-class,in-class and after-class.Through experimental research,this paper explores the feasibility and validity of the flip classroom based on micro-class in the teaching of "elements and their compounds",and provides operational teaching suggestions for the teaching of "elements and their compounds" according to the experimental results.
