语义图示工具影响课堂学习生态的研究

The Research of How Semantic Diagram Tool Transform Classroom Ecology

利用学习技术变革课堂学习生态,是学习科学研究领域的核心议题。从理论上看,作为可视化学习技术的典型代表,语义图示工具具备变革课堂学习生态的潜质。为了论证这一观点,通过设计并实施两个学习实验,分别探究了语义图示工具对学习过程中师生交互以及小组交互过程产生了何种影响。在对实验中课堂视频和小组对话的编码分析中,可以发现:在课堂中整合语义图示工具可以让教师从知识传授的角色中脱离出来,更大概率地发挥教学促进者的作用;还可以使小组学习者在有限的学习时间里,更大概率地投入到可以引发有效学习的学习活动中,从而实现课堂学习生态的转变。这对语义图示工具在教师专业发展、学习技术设计等方面的研究具有指导意义。

How to use learning technology transform the classroom ecology is one of the key issue in the research field of learning science. From the theoretical perspective,semantic diagram tool,acting as a typical visualization learning tool,has the high possibility to transform the classroom ecology. In order to testify the claim,two learning experiments were designed and implemented to investigate how semantic diagram tool mediated the teacher-student interaction and group interaction. After analyzing the classroom video and group discourse data,it is found that semantic diagram tool can make the classroom ecology changed in the two way. It not only can make the role of teacher change from knowledge transfer into knowledge promoter with a high possibility. It also can make group learners engaged into more cognitive-demanding learning activity with a high possibility. Based on the findings, the direction of future researches, such as teacher development, the design of learning technology, are discussed in the end.
