Interactive rule and control in Blended Collaborative Learning

Interactive control is an important part of Blended Collaborative Learning\´s (BCL) guidance and control. This paper, which is based on the continuous iterative practice in five years, discusses the interactive types of BCL, and summarizes 6 rules of BCL interactive: alternative rule of interactive way; common rule of interactive region; selection rule of interactive content, media, and object; three-elements rule of BCL groups effective interaction; interface impedance rule of interactive operation; implicit reconstruction rule of self-reflections interaction. Meanwhile, this paper establishes a 10-dimension state-space model of BCL interactive variables, analyses the interference factors and interference effects in BCL interaction, puts forward the design principles of BCL interactive control, and specifically describes "multivariate guide control method", which can help control the BCL interactive adaptation period.
