The Quality Problem of Network-based Distance Instruction:A Perspective of Integration of Teaching and Learning Behaviors

In network-based distance education,a quasi-permanent separation between teacher and students,as well as students and students in time and space made a same quasi-permanent separation between teaching and learning.In order to ensure the quality of distance instruction,the separated teaching and learning must be artificially re-integrated.One of the most important ways of the re-integration is to establish online course forums for students to interact with teachers and with other students.Based on a qualitative and quantitative analysis of the content and number-of-students of interaction in the 20 samples of online course forums,this paper discovered that,in online interaction,the bystanders are in the majority,the academic interaction is not very high,and the non-academic interactions problematic.These phenomena demonstrate that,in the present network-based distance education,the effectiveness of teaching and learning integration allows of no optimism and many problems remain regarding to the quality of network-based distance instruction.
