Micro-lecture Categories Development Strategy Based On Knowledge

Micro-lecture is widely loved by learners, it attracted the close attention of educational experts, scholars and teachers, because of its distinctive theme,functional diversity, ease of learning and so on.The study found that, in 2013 and before, the study of micro-lecture mainly limited in discussion of its concepts, definitions, characteristics and forms.Nearly two years, the studies of micro-lecture have transited to applied design of specific subjects and applied study of specific scenarios, however, the theoretical guidance for the development study of micro-lecture is relatively few.First, based on content analysis, this paper studied the theory of knowledge classification, analysis cognitive structure and property characteristics of different types of knowledge, whereby micro-lecture is divided into five types, namely: type of theme-lecturing, problem-solving,experimental operation, phenomenon reflection as well as the course of metacognitive knowledge.Secondly, researching in five types of micro-lecture development strategy.According to the emphases of knowledge, we proposed different types of its development strategy, and gave specific design ideas and presented information processing methods and precautions.Thirdly, guided by micro-lecture characteristics, this paper proposed the design process of its development strategy, which has the characteristics of knowledge classification theory, providing a flow chart of the development and design, illustrating the need analysis, content selection, media information selection, writing methods of scripts and other many aspects of micro-lecture.Finally, selecting the course, "Computer Application Foundation", as the applied practice object of research results, using screen recording software,Camstansia Studio, develops and designs curriculum cases. The finished micro-lecture were used in the real classroom teaching, according to the implementation, utility analysis is found that micro-lecture of categories development strategy compared to the general micro curriculum, has a better presentation in rich media screen, strong attractiveness, relatively better on operability, good teaching effects.
