The Application Research On Broadcast Mode Of Screen Broadcasting In Operation Course Of Information Technology

With the development of the information age in the 21st century,the teachers'teaching methods have been greatly enriched.Both college and high school,teachers are accustomed to using multimedia teaching to improve students' learning efficiency.In order to give full play to the advantage of multimedia teaching in computer room,screen broadcasting systems have been widely used in the teaching of computer courses.In many computer rooms of primary and secondary schools,various screen broadcast systems are installed.And these different screen broadcast systems have the same functions:screen broadcast,class management,student presentations,remote control,File management,screen lock and so on.In class,teachers usually use the screen broadcast function to explain knowledge and demonstrate the steps to students.this research is based on two different screen broadcast methods in the cloud classroom screen broadcast system to study the learning outcomes of students.And the two different screen broadcast methods is full screen broadcast and window broadcast.This thesis consists of six chapters,the specific structure as follows:The first chapter is the introduction,mainly expounding the background of the research of this topic,and then combing the status quo of using screen broadcasting systems in computer classes at home and abroad,and then explain the research significance of this research and topic.Contents and methods are explained.Finally,the theoretical basis of the supporting practice process is systematically elaborated.The second chapter mainly defines some related concepts in this study and elaborates the theoretical foundation of the teaching practice process in this study in detail.The third chapter analyzes and designs the teaching objectives,learning conditions and teaching strategies of this education practice,and designs the teaching process based on the cloud classroom screen broadcasting.Finally,it collects and organizes the teaching materials.The fourth chapter designs the object,the process and the methods of experiment,and completes the teaching experiment in flash animation lesson on sophomore students.The fifth chapter analyzes the data collected in the experiment and draws the experimental conclusion.The sixth chapter is the summary and prospect.It summarizes the contents and innovation of this study.At the same time,the author also looks into the follow-up research future and the study direction.
