| With the rapid development of Internet,mobile communication and other technologies,live online teaching,as a new way of learning,has gained more and more people’s favor.As a new form of online teaching,live online teaching provides new development and opportunities.Learners and teachers in various regions can be closely connected with each other relying on live online teaching to break through time and space restrictions.However,due to the different learning Spaces of teachers and learners,there are still many problems in this learning method,such as the lack of ideality of learning effect,lack of good interaction,one to the end,and so on.Therefore,strengthening interactive design in live teaching is an important way to improve learners’ sense of experience and participation.First of all,therefore,the research analysis and expound,including social telepresence,teaching interaction,related theory,the related literature live teaching mode is analyzed,explained based on the theory of activity under the guidance of the necessity of building a live online teaching mode,and work is introduced in this paper,we study the concrete method,content and way of thinking.Taking practical research as the starting point,this paper investigates the basic situation of online live broadcast learning in depth.Through logging in many relevant platforms,observing the actual situation,and adopting questionnaire survey,the problems existing in the implementation of online broadcast teaching are clarified,such as the need to improve the learning effect,the lack of effective interaction between teachers and students in teaching,students’ self-control ability and learning attitude,etc.,which still cannot meet the teaching requirements.Based on the basic status quo of the current implementation of online live broadcasting teaching and the theoretical framework of activities,the system structure of online live broadcasting teaching is studied and a hierarchical model related to it is built,which involves three levels,namely,operation,behavior and activity.A dynamic relationship model is built for the major elements of the online live teaching activity system,specifically involving the three core elements including learning community,learning subject and object,and the four non-core elements including communication rules and learning results.The construction process model for the design of online live teaching activities involves three stages,namely,preliminary analysis,activity design,and environment design supporting mobile learning activities.Based on the specific stage of classroom teaching,this research has constructed corresponding processes for online live broadcasting teaching respectively before,during and after the live broadcasting,and described the learning activities of online live broadcasting respectively from the perspectives of learners and teachers.From the perspectives of interactive teaching theory,sense of social existence,and learning community theory,and based on the teaching model of online live streaming,various optimization strategies that can make online live streaming teaching more effective and efficient in the teaching process are explored:(1)improve learners’ sense of cognitive existence through problem solving;(2)Promote the emotional communication of online live teaching community;(3)To improve learners’sense of social presence in online live teaching;(4)Cultivate metacognitive ability to correct attention distraction;(5)Give play to the role of teachers’ image behavior in online live teaching.Finally,from the perspective of the final conclusion of the study,the achievements and shortcomings of this study are summarized in the hope of providing corresponding reference for many workers in online broadcast education. |
