问题解决在线协作学习中的角色设计研究

The Research of Role Design in Problem-solving Collaborative Learning

角色规定了CSCL中学习者所承担的权限和任务，是CSCL研究关注的核心要素。本研究将角色引入问题解决协作学习中，从协作任务和问题解决认知加工两个维度构建了角色设计框架。研究将角色设计框架应用于具体问题解决协作学习中，部分验证了框架包含角色的有效性。研究结论认为，问题解决协作学习活动所采用的三类角色能够增强学习者在线问题解决学习的效果，并提升学习者对学习的主观感知。

The role defines the learners ’permissions and tasks assumed in CSCL. It is core element of the CSCL. This study constructs role design framework which consist of cognition process of problem-solving and collaborative task. This research verifies effectiveness of the three kinds of roles in role design framework. It concludes that three kinds of roles could enhance the effect of problem solving and improve the learner ’s subjective perception of learning activities.
