Research On The Application Of Microlecture In Junior Middle School Students' Ability Of Information Acquisition

One study showed:the knowledge update cycle was sharp reduced to 2-3 years in the 21st century.This not only comes into violent collision with the traditional view of knowledge,but also a profound impact on people's learning concept, giving birth to the times change of a lifelong learning.The social demand for talents has changed dramatically,the society calls for talents who are good at learning and have good information literacy. Fast and accurate access to information is a kind of identification of information acquisition ability, and as an important index of information literacy, it becomes more and more important.The first secondary school of Central Normal University is the experimental school.This paper investigates the status of information acquisition ability of junior high school students, and the micro-class is applied to teaching practice. Meanwhile, in order to promote the development of the junior middle school information technology curriculum and provide some reference for the application of micro-class in basic education, the paper explores the design ideas, and application models which using micro - class to enhance the ability of information acquisition.This study uses literature analysis, questionnaire survey, experimental research methods and other methods. To understand the status quo of information acquisition ability, I have read some domestic and foreign literature. This paper analyzes the current information technology subject status in high school and the existing problems through the questionnaire survey. Studying and analyzing the results of the survey to design and develop the micro-class for the existing problems, and eventually the micro-class is applied to teaching practice. Finally, analyzing the application effect, exploring the information acquisition ability to improve micro-class design process and application prospects in course teaching. This study mainly from the following aspects of a detailed discussion:First part: research background, literature review and research content, methods and significance.Second part: theoretical basis. This research is based on the theory of constructivism and multimedia learning, and expounds the realistic basis of the teaching design of information acquisition.Third part: investigation and analysis of information acquisition ability. In the third chapter, a questionnaire survey was conducted among the four classes of the first year of the experimental school, and 207 were distributed, and 207 valid questionnaires were retrieved.Fourth part: micro-class design. On the basis of investigation and analysis in the third chapter, selecting the appropriate teaching contents, materials, production tools, and eventually producing a micro-class video.Fifth part: teaching practice. Combine with the micro-class which the author designed to design teaching.Sixth part: research conclusions and deficiency. Summarize the conclusions and shortcomings of this paper for others to learn from.
