The Practice And Research On Micro Lessons In Chemistry Teaching Of Rural Junior Middle Schools

In the micro information era of the rapid development,"Micro learning" is slowly into our study lives.In recent years,the rise of "micro lessons" in education has promoted the development of micro lessons in various specific subject areas.The discipline of junior middle school chemistry will inevitably be swept by the tide.Chemistry is a new discipline for students to enter the third year of junior middle school.It is an enlightenment stage for students to study chemistry and also an important part of junior middle school teaching.Students' initial contact with chemistry is full of curiosity and interest,but the knowledge of junior middle school chemistry is fragmentary and,and the teaching form of the rural junior middle school is traditional and single,and there is also the existence of the pursuit of scores to speed up the teaching progress,which leads to the decline of students' interest,the decrease of enthusiasm,and the teaching effect is not ideal.Therefore,how to carry out effective and efficient chemistry teaching in rural junior middle school,directly related to the growth and the development of students.As a new teaching mode born in the new curriculum reform,micro lessons has been widely used in classroom teaching.This paper studies the practical teaching of micro lessons in rural junior middle school chemistry teaching.Through the literature,we've reviewed the development of micro lessons at home and abroad.,and through a questionnaire survey,we know the current situation of chemistry teaching and students' chemistry learning in three rural junior middle schools in Lianyuan.On this basis,in combination with the characteristics of rural junior middle schools and rural students,micro lessons should be given full play in its advantages of short and timid,strong pertinence,perfect knowledge system,etc.In addition,the results are reflected from three aspects,such as score comparison,questionnaire survey and teachers' interview.The study found that:(1)micro lessons teaching has improved the academic performance;(2)micro lessons teaching increases the interests of learning chemistry;(3)micro lessons teaching can be accepted but not the favorite;(4)the popularization of micro lessons teaching in rural junior middle schools is feasible but still subject to the objective conditions.Finally,in combination with the conclusions of this study,the suggestions are given for the teaching practice of micro lessons in chemistry teaching in three rural junior middle schools in Lianyuan,and the practical experience is provided in the application and popularization of micro lessons teaching in rural area.
