The Design And Application Of Micro—lesson Of "information Technology Foundation" In High School

With the rapid development of the “micro-era”, more and more new things, new media are named after “micro era products”. As one of the micro era products in the field of education, micro-lesson is booming. Micro-lesson, as a new kind of digital learning resource, has had a huge influence on the processes of teachers′teaching and students′ learning, which changes the traditional teaching methods, teaching resources, teaching models and so on. In this study, a senior middle school is treated as an experimental school to discuss the design ideas,application mode and effect of micro-lesson used for teaching of high school "Information Technology Foundations" course, in order to promote the development of micro lesson of high school information technology teaching, make up for the shortage of teaching resources, and improve the high school teaching of information technology, and also provide reference for the application of micro-lesson in specific subjects in basic education.In this study, literature analysis, questionnaire investigation, observation and other methods are used. Research present status is organized and the concept of “micro-lesson” is defined in the literature review part. The object of the study includes 158 students from three classes of a high school senior grade one, who participate in "Information Technology" course, and they were asked to do a questionnaire, take the micro-lesson. Through the questionnaire, the author analyzed the current status of school IT teaching and existing problems. Through the analysis of the results of the survey, the author designed a micro-lesson and applied it to the teaching in order to solve the existing problems. The author also analyzed the application effect, and explored the design process and application prospect of micro-lesson for high school "information technology foundation" course.This paper is discussed from the following aspects in detail:The first part includes the research background, literature review and theoretical basis. The first chapter of introduction mainly describes the source of the problem, the research background, the significance, the research content, the research purpose and the research methods. In the second chapter, in terms of the definition of micro lessons by educational technology experts and scholars, the author came up with the definition and characteristics of micro-lesson which is recognized in this study. The author discussed the present situation of research at home and abroad on micro lesson, and took the time order to see the different stages of development and continuous improvements of the micro class. The theoretical basis of this study also has been discussed and explained.The second part is about the preliminary investigation analysis. In Chapter three, a questionnaire survey was conducted in three classes of the first grade students of an experimental school. 158 copies were distributed and 157 copies were recovered, excepting one useless copy. The questionnaire shows the feasibility of the current school information technology teaching status and the implementation of micro lesson. The statistical analysis of the survey data reveals three existing problems in the information technology teaching present situation, based on which, corresponding solutions to the problems are proposed.The third part is about the design and production. On the basis of survey analysis of chapter three, and after choosing the appropriate course content, materials, production tools, selecting twelve knowledge points, and combining with his own practical experience of participating in the construction of micro-lesson resources, the author personally designed about 10 micro-lesson videos. In the fourth chapter, according to the micro-lesson design flow chart, the author listed five cases of micro-lesson design scripts, to explain the material selection principles and production methods.The fifth chapter is the fourth part. In this chapter, a micro-lesson instructional design was made according to the author’s personally designed videos. This instructional design lists three other cases of micro lesson instructional designs from the aspects of teaching materials, teaching objectives, analysis of learning situation, the choices of media, the teaching process and the teaching reflection. After practical application, a second questionnaire survey was conducted among the same 158 students, in order to know the application effect of micro course resources and the attitudes and advices to subsequent micro-teaching promotion.The fifth part is about summary and outlook. In this part, the achievements, characteristics and innovation in this study are generalized and summarized. Besides, the existing shortcoming of this study is pointed out objectively in order to show the right direction for the further researches.
