construction for <The Learning of Science and Technologies>，< Knowledge Management and Learning Organization> of educational technology. And this study constructs the teaching design pattern of micro-lesson. Then it selects four micro-lessons as cases of study，and analyses its process of creation. Finally，it refines the six processes and the five principles of creation on micro-lesson. At the same time，it integrates and summarizes several kinds of supplementary teaching resources.

Subsequently，taking the micro-lesson of <How to Conceive the Micro-lesson> and <The Golden Rule of Changing Habits> for examples，this study designs and implements the teaching activities of

“Application of micro-lesson in the classroom”and “Application of micro-lesson before the classroom”，and analyses the applied effect of micro-lesson and micro-curriculum from the five aspects. From the process of creation on micro-lesson and received awards，achievements and social repercussions，this study can draw two conclusions.

This study still has some shortcomings and areas for improvement，therefore，it summarizes the conclusions of research in the finally，and proposes the features of research，at the same time，it points out the lack of study and the subsequent direction on research.
