The Current Situation Investigation And Countermeasures Research Of Micro Course Of Chemistry In Middle School

Micro Course is a innovation that combines modern information technology and education,which is a micro video explanation for a particular knowledge point.It combines video with audio and its abundant visual and auditory effects can draw the attention and arouse the interesting of student.On the one hand,being in adolescence,the middle school students' attention is not easy to concentrate and vulnerable to outside interference.On the other hand,they show great enthusiasm and interest to new things.The introduction of micro learning resource provides a channel for the solution of this problem.Chemistry,with characteristics of abstract knowledge and plenty of experiments,is an experimental subject which studies the matter at the level of molecular and atomic.By introducing the micro learning resource to the chemistry teaching,it can display the micro world so that knowledge can be macroscopical and not abstract and help students to understand knowledge.At the same time,it is greatly useful to improve students' experiment skills according to show the operation process of experiment clearly and standardized,and then improve teaching efficiency.At present,more and more middle school chemistry teachers apply the micro course to the teaching practice,but the teaching effect needs to be further verified.This paper attempts to understand the present situation at home and abroad of micro learning resource by documentary research and defines the relevant concepts,meanwhile designs questionnaire for students and teachers to investigate “the current situation of application of micro course in middle school chemistry teaching”.It analyses the current situation of “application of micro course in middle school chemistry teaching” by means of questionnaire method and puts forward corresponding measures,which provides reference for micro course servering for chemistry teaching.Through the overall analysis of the questionnaire,it is found that existing problems about application of micro course in middle school chemistry teaching mainly reflected in:(1)Not only the teacher don't know enough about micro course platform,but also micro course on the relevant platform is poor and the classification of resources is confusing.So it is difficult for the teacher to find the required micro learning resource;(2)The atmosphere of application of micro course in school is bad and the teacher only apply micro course in public class and competition and seldom in daily teaching;(3)It is short of typical type of the application of micro course inmiddle school chemistry teaching for teachers to draw lessons from and study;(4)The teacher know little about micro course,the level of the design and production of micro class is low and can not apply the micro class flexibly in the teaching of Chemistry;(5)The characteristic of "fragmentation" of micro learning resource influences students' systematic learning of knowledge.For current existing problems,the author puts forward the following countermeasures :(1)Perfect micro learning resource network platform;(2)Optimize the application environment in school;(3)Construct typical micro learning resource application types of chemistry in middle school.(4)Improve the ability of teachers to use micro learning resource for teaching.
