| With the advent of the "micro era",the word "micro lesson" arises at the historic moment.Now,as a new online teaching resource,video micro lesson not only changes the traditional teaching method,but also leads the trend of video micro lesson in "impart knowledge,impart knowledge and explain doubts",so that teachers’ teaching process and students’ independent learning have been improved.However,the single interactivity of video micro-class makes it difficult for students to take initiative in micro-class,which greatly reduces learners’ interest in learning,affects learning efficiency,and further reduces the teaching quality of video micro-class.The loss of interaction limits the brain’s ability to learn and store knowledge,not passively,but in a responsive and interactive environment.Therefore,it is the focus of current research to discuss the interactivity of video micro lecture.The purpose of this study is to explore the synchronous interaction mode of video micro-class,classify the synchronous interaction mode of video micro-class,further elaborate the design ideas and implementation methods of each kind of synchronous interaction mode,and select one or two of them for development.To meet the interactive needs of learners for video micro-lesson and improve the teaching quality of video micro-lesson.In this paper,the design and development of the interactive mode of video micro lecture are divided into four parts.(1)this paper defines micro-lessons and related concepts,discusses the classification and characteristics of synchronous interaction of video micro-lessons,and discusses the relevant theoretical basis of video micro-lessons.(2)this paper expounds the concept of synchronous interactive video micro-lesson,and obtains the interactive demand for synchronous interactive video micro-lesson through the form of questionnaire survey,and then designs the interactive mode of synchronous interactive video micro-lesson through the interactive demand.(3)taking the knowledge points in the section of "preliminary knowledge of flash" in the course of flash project tutorial as the case object of synchronous interactive video micro-course,the design of synchronous interactive video micro-course was carried out.(4)the development ofsynchronous interactive video micro-class is divided into two development.The preliminary development uses Adobe Premiere video editing software to develop and design characters in video micro-class.Further development is based on the development of We Chat small program interaction node,the realization of a specific time node for synchronous interaction.Through the research,it is found that improving the interactivity of video micro-lesson is beneficial to students’ learning initiative and their interest in video micro-lesson.To the teacher can strengthen the teacher’s teaching behavior;As for video micro-course itself,it can effectively improve the teaching quality of video micro-course and make video micro-course more interesting,learnability,lively and participatory. |
