The Study Of Micro-lecture Guidance Review Of Teaching In High School Chemistry Experiment

Chemistry is a branch of natural science based on experiments.In the teaching of chemistry in middle school,experiment teaching plays a very important role.A new round of elementary education reform sets its goal of improving students' scientific literacy,and promotes students' independent and active learning.In terms of chemistry as a discipline,chemical experiment,which reflects students' comprehensive quality in a best way,poses a very important position in chemistry teaching.Chemistry experiment constitutes not only a vital part in middle school chemistry,but also a significant means of the implementation of chemistry curriculum reform.Course review in high school is of great importance,with limited time and heavy task;therefore the efficiency means a lot.In previous review classes,teachers impart knowledge,and assign homework to students after class.With this mode of review,both teachers and students will easily get tired and the learning efficiency is not high.As a matter of fact,students do not lack knowledge;the problem lies in the fact that they can neither organize all the learned knowledge reasonably nor form their own knowledge structure,so as to improve the ability of solving chemical problems.In the review classes of chemistry experiments,it is difficult for teachers to represent the practical experiment.That traditional mode of review cannot give students sensory impact,thus students' learning is lacking of initiative.The teaching mode of micro-lecture tutorship is different from the traditional teaching strategy of chemistry experiments.it is formed against the context of education informationization advocated by the government and also on the basis of gradual updating of technology.The current studies of micro-lecture are mainly about the exploitation of micro-lecture and its application.However,it is only in the teaching practice that the real value of the combination of micro-lecture and specific subject teaching reveals.This paper put forward a teaching mode of combining micro-lecture with guide class,which is based on the exploitation of micro-lecture resources,and the current research on the application of guiding classes.With this teaching mode,students may actively learn by themselves with the help of micro-lecture and guiding class,andthen their problems and doubts may be revealed and be exchanged or discussed in class.With the help of homework,the former problems and doubts will be deepened and extended,in order to achieve higher learning efficiency.The teaching mode of micro-lecture guiding class remedies the regret of review class of chemistry experiments.Micro-lecture video blends sound,animation,images,text content in such a reasonable way,and to make use of guiding class can improve students' learning autonomy,and promote students to carry on the construction of knowledge.Students can choose to review independently,which may yields twice the result with half the effort.
