Research On The Design Of High School Biology Interactive Micro-lesson Based On UMU

With the continuous development of information technology,the teaching method of combining subject teaching and information technology is widely used,and "Internet education" comes into being.As a new type of teaching resource,micro-class has the advantages of short and tough,autonomous learning and so on.With the wide application of micro-lessons in teaching,some problems are also exposed: the number of micro-lessons is many,but the quality is mixed;most micro-lessons are only micro-video,lack of relevant auxiliary resources,and poor interactive function.hence,this study explores the design of interactive micro-class on biology in senior high school based on UMU interactive learning platform.First of all,this study uses literature research to understand the research background and current situation of micro-lessons at home and abroad,as well as the application of UMU interactive learning platform at home and abroad,pointing out the current problems existing in micro-lessons research in China and the current situation that UMU interactive learning platform has not been widely concerned.and then guided by constructivist learning theory,cognitive load theory and learning pyramid theory,the process of making interactive micro-lessons based on UMU interactive learning platform is explored by educational experiment method.During this process,the functions of the UMU interactive learning platform are introduced in detail,and the advantages of the platform to do interactive micro-lessons are excavated.People teach high school biology compulsory one "into the fine Cell "," cell basic structure "," cell material input and output " three chapters as an example of the use of the platform for micro-lesson production,summed up the platform-based high school biology interactive micro-lesson design principles.Finally,the author applied the micro-lesson to the actual teaching,using the questionnaire method,interview method and combined with the students' unit test results to obtain the effect ofmicro-lesson application.Experimental results: the average scores of the experimental classes in the two parallel classes were higher than those in the control class,but the difference between the scores of one group and the other group was not significant.Data prove that micro-lessons based on UMU interactive learning platform are useful in improving students' learning interest and autonomous learning ability has a certain positive effect.At the same time,it also shows obvious advantages in improving academic performance.Because of the limitation of the implementation conditions,although the micro-class has achieved good teaching on the whole,the effect intensity is different in different cases.I hope that through this research,we can give full play to UMU interactive learning platform to quickly generate micro-lessons,as well as teachers,students and students can interact with each other to improve the quality of micro-lessons,broaden the channels of micro-lessons production,and achieve a variety of micro-lessons;at the same time,we hope that this exploration can bring inspiration and help to the design and research of subsequent interactive micro-lessons.
