The Research Of Design And Application Of Micro-lecture In Junior Middle School Information Technology Teaching

Information society, information technology will play an important role in many areas. Information technology curriculum as the main way of basic information technology education in our country,we should pay attention to it.However the teaching situation of current our country information technology is not optimistic,teaching resources in the form of a single, rigid teaching methods, lack of effective teaching time, students demand can not be effectively meet and so on, information technology teaching need to find a way to reform.Micro lesson as a digital learning resources, adapted to the needs of learning in the information age, its rise, provides a new method to improve information technology teaching.This study put micro lesson into information technology teaching,by educational practice to explore.Specifically, this study carried out as follows: through literature review, learn about the micro lesson evolution and its application status; through the questionnaire survey, learn about the present situation of information technology teaching, learn about the needs of teachers and students of new learning resources and teaching methods; with the micro lesson design, put forward the scientific, practical, system,targeted, art five principles, and to develop a micro lesson design table; combined with the existing research and teaching practice, construct the teaching strategy,pointed out that the micro class application need to adhere to the principle of auxiliary,combined with the actual teaching and flexibility, and as “using text create an envelope box "and" using Excel making sales report "to cases; through the questionnaire survey, classroom observation, performance evaluation, interviews and other forms, analysis the effect, the experimental data shows that micro lesson in the information technology teaching has positive effects on micro lesson to stimulate students interest in learning, enhance confidence in learning, promote academic performance,changing teacher-student relationship,optimizing classroom management etc. In the end,in view of the limitations of the study, put forward the problem which need to pay attention,solution method and explore the future focus.
