问题解决在线协作学习中的问题设计研究

Research on Problem Design in Collaborative Problem-solving Learning

问题设计是问题解决学习中知识建构的基础,是问题解决学习得以开展的前提条件。首先,研究分析了问题解决在线协作学习所针对的问题,在性质、组成信息等方面的基本特征,并针对上述特征,提出由意义信息、支持信息和知识线索组成的问题设计结构。其次,实证研究部分利用准实验研究的方法,验证了问题设计结构的有效性。实证研究的结论认为,问题设计结构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。最后,结合具体的设计经验,研究给出了问题设计的具体策略。

Problem design is both the basis of knowledge construction and the premise condition of problem-solving learning. Analyzing basic characteristics of the problems such as character,information structure,the study puts forward the problem designing structure which consists of meaning information,supporting information and knowledge clues.Empirical researches,with the means of experimental research,verify effectiveness of the problem designing structure.The results show that the problem designing structure can enhance the effect of problem solving and improve the learner＇s subjective perception of learning activities.Finally,the strategies of problem design on the basis of specific designing experience are put forward.
