Practice Research On Micro Course In The Review Teaching Of Middle School Chemistry

With penetration of social informationization everywhere,micro teaching gradually enters our campus.Micro class mainly refers to teaching activities built around certain knowledge or a certain teaching link.They are under the request of new curriculum standard and teaching practice and on the carrier of 5-10 minutes of video.Micro teaching provides students with independent learning platform.Besides,it meets some students' different need of personalized learning.It is also an important supplement of classroom learning and development.But now studies of micro class's effect on the teaching are insufficient,so I apply it in the teaching of middle school chemistry review classes to study the effect of micro class on teaching.This thesis mainly includes two aspects,theory research and practice research part.In the theory part,it mainly discusses the following three aspects of content.1.Define the connotation of the micro class under the guidance of relevant theories,the micro courses,miniature and regular classes,based on micro class research status at home and abroad.2.According to the characteristics of the middle school chemistry overview of general principles of micro course design,I design patterns,and micro teaching way of recording and so on.Under the guidance of the concept,I design and construct chemistry practical recitation of micro teaching cases.Micro teaching content knowledge is centered teaching method,experimental demonstration and guidance in three aspects,for example,respectively by carding unit knowledge class recitation,laboratory gas producing special recitation,integrated to explore the topic of the thematic recitation,are detailed in this paper.3.Design chemistry review strategies in micro lesson teaching of junior high school based on the structure of classroom and the requirements of the school put forward "Jane classrooms".In practice research part,select the sample,the specific case in the form of small class teaching,and is used in the chemical recitation teaching practice,questionnaire survey and the result of the implementation of specific system evaluation,the conclusion:micro lesson in junior middle school chemistry review can be implemented in the teaching,not only improve the efficiency of review,also improves the ability of autonomous learning.The final papers prospect micro lessons for middle school chemistry development from the renew the idea,strengthen learning,strengthen cooperation and promote micro course resources development and the construction.
