Construction Of Microlesson Resources For Physical Optics Section In Junior High School Based On Learning Progression

In recent years,with the development of information technology and the continuous renewal of educational ideas,micro class has become a combination of traditional education mode and new education mode,which has attracted more and more people’s attention.With its short and vigorous learning mode,the micro class is very popular among teachers and students.Therefore,more and more micro class platforms and micro class resources appear like bamboo shoots.Most of the teachers in the production of micro lessons in the text of the chapters as a single section of the content,also with the key points of the subject for the content of the framework,and more in the form of exercises to explain the form.Learning progression is a description of the way of thinking in which students learn and explore a topic in a span of time.As a new concept of scientific education,learning progression has been applied in many aspects and fields.In the course of designing some science courses in our country,we also use learning progression to plan the development of core literacy.At present,the teaching content of middle school physics is mostly in the form of one module,and because of the limitation of the characteristics of the micro class,many micro class resources are too fragmented.Many students can only find a small lesson about a point of knowledge or difficult problems when they use micro class resources,and the content of our middle school physics teaching is a whole and coherent system.This way can not give full play to the characteristics of the micro class.This paper attempts to build a systematic and effective micro class resource based on the two chapters of junior middle school optics,which can facilitate the study of the students’ system or review the physical optics part of the whole junior middle school.
