The Application Of Micro-lesson In Junior High School Physical Experiment

In recent years,the development of the informational education in China is rapidly,to merge information technology and education is the direction of informational education development.With the widely popularization of intelligent mobile phone and the rapid development of communication technology,and micro-lesson,has become a new type of learning resources,because of its features of small and micro targeted,has received wide attention and application in society,and affect the future development of education in junior middle schools.Despite the rapid development of micro-lesson in various fields,there are still some problems in practical application in the educational field of primary and secondary schools education,especially for physical experiment course,the highly practical curriculum is.The micro-lesson has a long-term significance on the research and development of physical experiment teaching.In order to study on the effectiveness of design and application of micro-lectures in the junior middle school physics experiment course,this article selected physics teachers and students those in Grade 2 and Grade 3 of junior middle school in Xiangtan as the research object,and chosen questionnaires,semi-structured interviews and participant observation as the mainly research method.This whole paper consisted of four main parts.The first part is collecting and studying on literature,analyzing and summarizing the development of education informatization,the trends of micro-class and researches on it in recent years at home and abroad.Then make the research contents,research objectives,research methods and research objects more clearly.The second part is about finding many problems such as lacking of teaching equipment and teaching time,classroom's disorder and other issues in physical experiment course,with the investigation and study on junior middle school students and teachers.Through analyzing the characteristics of the students and functions of micro class that include simple production,vivid presentation,easy to spread,repeatability and so on,making sure the demand and feasibility of micro-lesson aids teaching of physical experiment course.Part three is about micro-lesson design with the clear principles of teaching and the excellent cases of domestic and foreign related micro-lesson studies.Selecting a class hour of physical experiment course of grade 2 in junior middle school as the research carrier,combine with author 's knowledge,content of courses,and teaching demand,analyzing the teaching target and the compose of physical experiment,design application of micro-lesson and implementation of micro teaching,record its performance to providing real case for micro-lesson using in physical experiment course.The content of part four includes senting out and collecting questionnaire,doing post-course interviews,gathering and analysing the learning estimates of the micro-lesson of physics experiment course between junior high school students and teachers.And then,finding the use of micro-lesson in physical experiment course not only can effectively alleviate the teaching contradiction in class,but also help students build on experimental knowledge,promote classroom interaction by saving teachers' time and energy,promote educational equity throngh maintaining class in order,cultivate students' habits of self-study,enhance the application effect of lifelong learning ability.
