Study on the models of the collaborative learning systems and proposal to the standardization activities

As a new learning method in global age, the collaborative learning gathers many interests. In collaborative learning, through the discussion among the learners about shared problems, they acquire the skills such as problem finding skills, problem solving skills, self-regulate skills and communication skills. In collaborative learning, the interactions between learners play an important role. To make it easier to design a learning environment where desirable interactions occur, it is necessary to have a description system to express the learning process explicitly. We describe that the description system enables us to develop the tools to design the learning process involving the interactions between learners, and to develop the tools that execute the designed process symbolically to show the feasibility of the process. Finally, we describe that the description system can be used as the basis of the collaborative activity record format standard that is currently being progressed in the collaborative learning technology WG in ISO/IEC JTC1/SC36.
