设计语义图示工具促进深度理解的实证研究

An Empirical Study of Designing Semantic Diagram Tool to Promote Deep Understanding

基于认知负荷理论,本研究提出了在协作问题解决中整合语义图示工具促进学习者深度理解的学习技术干预思路,并设计了验证这一思路有效性的对比实验,即在实验组整合了语义图示工具,在控制组整合了常见的基于文本的协作学习工具。对比分析小组对话数据发现,语义图示工具能对协作问题解决的学习过程产生有效影响,即提升团体投入质量;对比分析学习者深度理解的前后测数据发现,语义图示工具能对协作问题解决的学习结果产生有效影响,即引发个体的深度理解。作者期待这些研究发现能为教师变革课堂教学提供实践性的改革思路。

The design of learning technology is one of the key research issues in the learning science field. Based on the cognition load theory,this study proposes a new approach to learning technology intervention that integrates semantic graphic tools into learners' deep understanding in collaborative problem solving. To verify the effectiveness of semantic diagram tool,a comparative study was designed. In the experiment group research context,semantic diagram tool was integrated into the collaborative problem solving project,while in the control group context,the web-based collaborative editing tool was integrated. compared to group dialogic data,it was found that semantic diagram tool that was integrated into collaborative problem solving process can improve the quality of group engagement. It can engage learners more into cognitive-related learning activity and less into social-related learning activity. After comparing the pre-and post-test data,it was found that semantic diagram tool integrated into collaborative problem solving process can promote student's deep understanding. The study can provide some insight of designing effective learning tool to promote collaborative problem solving.
