The Application Of Micro Class In High School Chemistry Stratified Teaching

The new round of basic education reform spread across the country,the core concept is: for the rejuvenation of the Chinese nation,for the development of each student.This determines our country basic education curriculum system to carry on the transformation.How to make every student to develop,from ancient times,is a topic of common concern for every educator at home and abroad.With the rapid development of information science and technology,all kinds of mobile terminal equipment come out of our life.the combination of curriculum and modern information technology makes it possible to teach students in accordance with their aptitude.The use of Micro-Course Online Video in the teaching of chemistry,for each level of the students to provide a suitable learning platform,improve the teaching efficiency,hierarchical homework,stratified assessment is more conducive to improve students’ learning interest and academic performance.This paper summarizes the domestic research status of Micro-Course Online Video and hierarchical teaching,analyzes the concept and characteristics of Micro-Course Online Video and hierarchical teaching,and proposes the application of Micro-Course Online Video in hierarchical teaching strategies,the whole link from the students’ learning situation,with micro video as the core,micro courseware into the teacher teaching design,micro-practice and students’ task,micro-reflection and integration into evaluation.The focus is on the design of Micro-Course Online Video in senior high school chemistry teaching in the application of teaching cases,and in the high chemistry teaching practice research.According to the monthly test scores,two classes with no significant difference were selected for the control experiment.The experimental class adopts the teaching method of Micro-Course Online Video combined with stratified teaching in theexperimental class,with the examination results as the important reference standard for students to stratification,learning objectives,exercises,classroom questioning,homework,evaluation and other teaching aspects of stratification,and design Micro-Course Online Video teaching practice,after the experiment,the experimental class is significantly better than the control class.Micro-Course Online Video is used in hierarchical teaching,which can cultivate students’ self-learning ability and improve the classroom teaching effect.Pre-class autonomous learning makes classroom learning easier and easier,and also can improve students’ initiative,so that students’ learning achievement,learning interest and learning initiative are improved.the combination of Micro-Course Online Video and stratification teaching mode in senior high school chemistry teaching is a practical teaching mode.
