The Development Research Of Micro-lesson Resources About "Amount Of Substance" Module

With the rapid development of science and technology,human society has entered the information age,which makes profound changes to people's life style,working style and learning style accordingly.Micro-Lesson with its characteristic of pithiness,not limited by time and space,to repeat the learning of a certain teaching content,and then to grasp the way of knowledge conforms to what the times request and in the field of education it attracts more and more people's attention.For a module to make a series of Micro-Lesson,give students an opportunity to build a serialized knowledge system and consolidate what they have learnt,in order to promote the students personalized autonomous learning so as to improve the quality of teaching.Although the Mongolian senior high school teaching condition is getting better and better but there is a shortage of teaching resources.So it is vital significant to develop the Micro-Lesson resources in Mongolian senior high school and apply it in practical teaching.This study summarized the achievements in research on Micro-Lesson at home and abroad,mainly based on learning theory and mastering learning theory and defined the related concepts about Micro-Lesson as well.The subjects for this survey were the students of science class and teachers of chemistry department in Tianshan No.2Middle School in Arhorqin,Chifeng.It adopted the means of questionnaire and interview and understand the present situation of Micro-Lesson in teaching From schools,teachers and students.It is proved that the application of Micro-Lesson in chemistry teaching is feasible,and the research prospect is very good.The survey selected “Amount of Substance” module in New Senior Chemistry for China Student Book 1 as the teaching content which included lecturing Micro-Lesson,problem solving Micro-Lesson and experimental Micro-Lesson.The lecturing Micro-Lesson included "amount of substance","molar volume of gas",and "the amount-of-substance concentration".The problem solving Micro-Lesson included "the Avogadro constant and inference","the conversion relation of amount of substance formula","the calculation of amount of substance concentration".The experimental Micro-Lesson included "the molar concentration of a solution".The application of Micro-Lesson in the actual teaching of a semester has gained a good teaching effect,which has satisfied the students' personalized learning through teaching practice.To promote the systematization and systematization of the students' knowledge structure,improved teachers' technical ability.Based on "Amount of Substance" content producted Micro-Lesson,enrich the Mongolian teaching high school chemistry curriculum resources,changed the way students learn chemistry,played a positive role in teaching,and for the future production and further in-depth study of Micro-Lesson provides a reference.
