The Development And Application Of Micro Videos Based On CTCL

It is generally accepted that technology has the potential to improve learners' achievement.But how to turn this potential into reality is a question that needs to be answered through empirical research.In recent years,a new paradigm of educational technology research called CTCL is presented,which integrates technology,content,and learners from the perspective of social culture.The CTCL research paradigm provides us with a new perspective to answer this question.In classroom,technology is often presented in the form of learning resources.According to the design of learning resources,it could present a variety of techniques in learning resources,and provide a variety of possibilities for answering the question.In this study,we will conduct an empirical study by using the CTCL paradigm and making micro-video learning resources as containers of technology.Explore how to use technology to develop micro-video learning resources that can effectively improve learners' academic performance and try to provide a possible answer to the question.In this study,we take the learning of “Optical Phenomenon” unit in junior middle school as an example,study the following four aspects and try to solve the research question.First,what is the theory of micro-video learning resource development under the CTCL paradigm? How to construct the theory? Second,what is the structure and function of the model of micro-video learning resource design in junior high school of Optical Phenomenon.How to use the model? Third,what is the development path of high school physics optical phenomena micro-video learning resources? Is the development path operational? Fourth,can those micro-video learning resources which we have developed,improve students' performance?Around these four aspects,the study investigates and analyzes the students' preconceptions that are related to Optical Phenomenon.It found that visual limitations have a negative impact on the construction of scientific ideas.This study constructs the theory of compensation for visual limitations(CVL),which uses the mechanism of“ from physiology to psychology,from perception to cognition”to provide students with physical and psychological compensation by technology.In order to change learners' misconception from the source,this paper proposed a Micro-Video Resources Design Model Based on Compensation for Visual Limitations and designed the development path of CVL micro video learning resources.Using this model,this study developed a series of micro-video resources regarding Optical Phenomenon.A quasi experimental study wasconducted to test the model and the resources.The results confirmed significant improvements in the conceptual change of the experimental group compared to the control group.This article contains seven chapters:The first,second and third chapters mainly show the background of the research,the research questions,the research summary,and the research design.The fourth chapter is the core of this article.This part elaborates the origin of CVL theory,the connotation of CVL theory,the structure,function and application method of CVL micro-video learning resource design,the path of CVL micro-video learning resource development.The fifth chapter is based on CVL theory,model and development path,to develop micro-video learning resources for Optical Phenomenon.Chapter 6 introduces the design,the hypothesis test and the conclusion of the study of quasi-experimental research.Chapter 7 briefly presents the conclusions of the research,the innovation of the research,the lack of research and the prospect of the research.
