The Exploration About The Design Of High School Biological Micro-lesson Which Based On Focusky

With the introduction of micro-lesson in China in 2010,micro-lesson has been attracted the attention of researchers with its short and pithy charm,and it get rapid development in our country.At the same time,in the process of micro-lesson development,some problems are gradually emerged: the current micro-lessons are mainly based on PPT recording screen and classroom recording,it seems more single,the level of quality uneven and so on.Therefore,it is urgent to change the single presentation mode and improve the level of micro-lesson's production.Focusing on the current research on the development of design,the author will use the Focusky software to explore the design method of deep zooming's micro-lesson which different from the PPT recording mode,in order to enrich the current micro-lesson types,and to improve the quality of micro-lesson.The study is divided into six parts.First of all,the author through CNKI,EBSCO and other databases to review the development of micro-lesson design and development,mastered the research background,analysised and understanded of the domestic and international research and the main design mode of micro-lesson;Secondly,the author analysised high school biology,student characteristics,Focusky software's advantages from the reality,under the guidance of the constructivist theory,cognitive load theory,Dell "experience tower" and other theories,the author put forward basic principles and A set of detailed system of micro-lesson design process: prerequisite analysis,topics,planning and design,material preparation,video integration,reflection perfect;Thirdly,in order to prove the feasibility of the design method,Cell structure "as an example,the author combined the specific content with the micro-lesson design and production,modifyed and improved it;Fourth,in order to understand the teaching effect of such micro-class,I will be finished to flip the classroom Form applied to the practice of teaching,and through unit testing,classroom performance observation,questionnaire,Teachers and students interviews and other ways to obtain the relevant evaluation and feedback information;Fifth,through the comprehensive results analysis,student performance and student evaluation,the author draws the depth of the micro-lesson can effectively enhance the interest in learning,improve student achievement,improve teaching effectiveness Finally,the author reviews the research process and makes a deep summary and reflection on the problems in the research.In a word,the author hopes that through this research,we can give full play to the advantage of the nonlinear display mode of Focusky deep zoom to break the linear single presentation mode,enrich the existing micro-class types and improve the quality of micro-lesson.And provide inspiration and help for the follow-up study of deep-scale micro-course design.
