Excellent Microlecture Analysis From The Perspective Of Multimedia Learning Cognitive Theory

With the rapid development of information and communication technology and the extensive and in-depth practice of technology in education,education technology innovation application represented by microlecture has attracted great attention in the industry.From meyer multimedia learning theory,this study collected for the current outstanding award elementary school mathematics lesson micro case analysis,evaluating whether it conforms to the principle of multimedia learning,analyze the present situation of its design Suggestions are given,then apply micro elementary school mathematics course design framework is put forward.The work of the institute is as follows:First of all,through the literature research to comb at home and abroad about the microlecture,multimedia learning cognitive theory study and the paper books,gradually determined in this paper to study the problems and the direction,and to the class and multimedia,the essay discusses the concept and research status of learning theory.Then elaborated the theoretical basis of this thesis,the multimedia learning cognitive theory,meyer's multimedia learning principle and the primary school mathematics discipline characteristic,for the paper's subsequent research lay the theoretical foundation.Secondly,it analyzes and studies the outstanding microlecture cases of elementary school mathematics.This study USES meyer's multimedia principles to conduct content analysis of the microlecture cases currently collected.The analysis is divided into three steps: first round coding analysis,second round coding analysis and in-depth analysis.The purpose of the first round of analysis is whether the preliminary micro class reflects meyer's multimedia principles,and then analyzes the two aspects of the overall score distribution and the proportion of microlectures that reflect each principle.The second round of analysis is to select the multimedia principles to reflect the better microlecture,and analyze the degree of its manifestation in each multimedia principle;Finally,the representative microlecture cases are selected for in-depth analysis.Finally,analyzed the status quo of elementary school mathematics class,and puts forward some Suggestions: clear micro class definition,grasp mathematics discipline combining site,determine the elementary school mathematics lesson micro resources the development and application direction.And according to the analysis results,follow the principle of mayer of multimedia learning,every principle for micro elementary school mathematics course resources in the targeted,specific and operable design method.The study found that the current primary school mathematics good microlecture in multimedia principle,space close,close to the time,the principle of channel,conversational principles,the principle of sound the six principles embodied better;The four principles of consistency principle,emphasizing principle,dividing principle and pretraining principle are lacking;The redundancy principle is poor.The study also found that the requirements of the principles of segmentation and pre-training can be reduced in the design of elementary school mathematics microlecture.In the end,this paper combines meyer's multimedia learning theory and the analysis of excellent microlecture cases of elementary mathematics,and puts forward the design framework of elementary school mathematics microlecture resources.
