Research On The Teaching Design Of The Grouped Experimental Micro-classes For Students Based On The Primary Teaching Principles

With the popularization of information technology and the deepening of education reform,micro-lesson,a new thing with the characteristics of "short and Pithy",burst out with strong vitality,designing and making micro-lesson has become a necessary skill for teachers.At present,the research focus of microcourse has shifted from microcourse making technology to microcourse content design,and more attention is paid to the discipline concretization of microcourse design.The premise of making "good micro-course" is to design "good micro-course".Professor Merrill’s primary teaching principle provides a new idea for the design of micro-course.This research takes the teaching design of the experimental micro-course as the research direction,finds out the insufficiency of the experimental micro-course design through the summary of the previous research results,and systematically analyzes the guiding function of the primary teaching principle to the experimental micro-course.This paper analyzes the teaching design of group Experiment micro-course from the aspects of junior middle school students’ learning psychological characteristics,teaching contents,teaching objectives,teaching principles,etc.,forming the teaching design mode of grouping experiment micro-course based on the first teaching principle.Three typical cases are designed by this model,and the results of the study are reasonable and effective.The purpose of this study is to enrich the design theory of physics experiment micro-course and help the first-line teachers to design a good teaching effect of physics experiment micro-course.
