Experimental Study On The Learning Effect Of Different Ways To Emphasize The Learning Video's Key Points

Currently,under the influence of pluralistic modes of learning,multi-media learning shows itself in kinds of ways.'Instructional Video' is chosen by learners as the media of learning new things by its intuitiveness and vividness.However,the quality of videos may have an impact on result of learning.So it's an interesting and important study subject on how to make a high quality teaching video.Making an excellent teaching video by the method of documentary analysis should include rigorous design of script,scientific ways of showing a picture and the technique of talking.This paper mainly focus on how to emphasize the key points in the video to increase students' studying efficiency and to promote the result of studying.Targeting on undergraduates,it studies the cognitive load,learning quantity,quality,result of learners,and kind of figures of eye movement in the process by 'Eye Movement Test',which includes the cooperation of key points and mouse guiding,and the position of key points without mouse guiding.The conclusion of the paper includes:during the making of teaching video,adding the tips of key points is recommended to boost the ability of better understanding and application of knowledge;under the circumstances of tips of key points,it will help learners to use more time to focus on the tips without mouse guiding,and then aquire much more learning resources,and better understanding;it's better to add mouse guiding if there is no key point tips,because it can help to release the burden,help learners to focus on learning contents much more,but the influence on score is not obvious;tips of key points are better to be set on the right of the video picture,no matter there is mouse guiding or not,which can help learners notice tips more and more,increase the quantity of studing resources,and get a much better comprehension of as much as knowledge.The conclusion of the experiment could provide theoretical basis for the teaching video makers and teachers,making it have grounds to follow to emphasize the key points in the progress of making the video,so then,making the learning video more better to assistance teaching,increase students' learning efficiency.
