Evaluation Of The Application Of Video Elements In Micro Class

With the rapid development of modern media technology,more and more new media technologies are applied to teaching,which enriches teaching.With the development of social fragmentation learning,people prefer to read and learn less meals.With the increasing popularity of Khan college,"micro lesson" has gradually entered our field of vision.Since 2015,the Ministry of education,the Ministry of education,the education management information center,the Central Audio-Visual Education Hall,and the electric education and other departments have jointly carried out the micro class competition.The micro lesson competition in China has been carried out in full swing with the theme of micro lesson system in full swing in China,and it has been carried out in2017 for third sessions,and has received extensive attention from the educational circles.Taking the winning works of the second national Mini class competition as an example,this paper evaluates 190 award-winning micro class works.This study mainly adopts the evaluation research method,combined with case analysis and content analysis,expert interviews and other methods for comprehensive research.The main contents are: first,using the content analysis method and expert interview method to determine the evaluation gauge of the video elements.The evaluation gauge is divided into three angles from three aspects.The video elements are divided into three angles of vision,hearing and audio-visual sense,and each of them has their respective two and three evaluation indexes under three angles.The second part is the evaluation of the selected micro class samples by the evaluation research method.In the evaluation,the author invited the biological and information technology two students to evaluate the samples in the reading study,completed the evaluation of the samples for three and a half months,and got the data;third was using the case analysis method.The evaluation data are combed and the conclusion isdrawn.The main conclusions of this study are from the three aspects of visual element,visual sense,audio-visual sense,and the application strategies in the micro lesson.The application strategy of visual elements is detailed in five aspects: words,images,colors,light and shadow,and composition.The strategies for the application of auditory elements are concentrated in three aspects: commentaries,background music and sound effects;the application strategies of audio-visual elements are concentrated in two aspects of sound and painting synchronization and motion picture.Based on visual expression,the paper takes the video element as the starting point to do micro class evaluation research.The conclusion obtained in this paper combines the advantages and disadvantages of the design and production of typical microcourses in China.It has a certain research significance for the development and application of digital resources with micro class as an example.However,the conclusions obtained in the study have some limitations.The writing of this paper is a very good beginning,and the author will be in the future study.We should invest more energy in further research in order to draw more objective and scientific conclusions.
