The Experimental Research On That How The Presentation Of Teacher Role Affect The Learning Effect In Micro Course

Micro course has become the key point of educational information construction and the hot issue for many of the researchers because of its features of being concise and clear.However,the amount of research of the psychological problems is still not very large,which makes the micro course could not achieve its goal of benefiting for most of the learners and is a waste of educational resources.This article includes three aspects which are subjective feeling of learners,cognitive processing and learning effects.In the article,the author will analyze the effects of the learners which are caused by different types of way of teacher' s presentation,and will pay attention to the learning experiences of the learners in order to provide some guidance for the overall design and edit of the micro course.The author determines the main issue of study by giving an analysis to the video of the micro course and then summarizing the features of the micro course presentation.After that,under the instruction of multimedia images linguistics research and theories of psychology,the author makes a research of Syntactic learning.And the author also has a research about semantics which means that the research is about multimedia elements and the types of learning resources.The author also discusses the learning effect of the different way of presentation and the teachers'impact in micro lesson.Using eye-tracking technology to carry out the empirical research,the author analyzes the influences on learning processing and recognizing processing caused by teacher's different position.The main content of this study are as follows:understand the learners'recognition and design preferences of micro lesson through the questionnaire survey,design two eye-tracking surveys to present the influence on learning processing and recognizing processing caused by teacher's different position which are based on the research of the knowledge type of the materials itself and the teachers' position in presentations.The conclusions are as follows:(1)Different types of knowledge require different presentation,different learning effect and eye movement processing.As for the declarative knowledge,the teachers'images influence the learners' cognitive processes and then affect the study effect.The study effect of micro course will be better using the method of teachers' presentation.For procedural knowledge,the effect of teachers' presentation for learning is smaller.Therefore,the micro course should be designed according to the different types of knowledge in order to optimize the learning process and learning effect.(2)The present position of the teachers affects the effect of learning.Because of the different locations of the teacher in the video scene,the learner's learning effect and the allocation proportion of the cognitive resources during the learning process positively related.If the proportion of cognitive resources is higher,the study results are better.The experimental results show that when the teacher is at the upper right of the video scene,the learners' learning results are better.(3)The teachers' presentation in the learning materials has no significant influence to the cognitive load of learning process.Although teachers' image has nothing to do with the knowledge,the experiment results show that the extra cognitive load influenced by the teachers' image is not significant.
