【摘要】：如何设计、利用信息技术提高学习绩效一直是数字化学习研究的焦点。本团队从学习科学视角入手,以"语义图示"为技术着力点,试图通过对图示方式的探索以及图示技术的设计与开发,增强信息技术支持的学习方式并提高数字化学习效果。理论上,在认知任务更为复杂的计算机支持的协作学习中,语义图示有潜力缓解认知负担从而为协作任务提供支持。本文试图探查作为可视化技术的图示方式与工具在远程协作学习中的使用成效,以了解图示工具在协作学习过程中的使用特点,深入挖掘图示方式与工具在协作学习中的潜力。论文通过文献与理论研究提出假设,采用干预自然教学情境的设计研究方法,将图示工具与方法应用于协作任务设计中,通过观察与访谈收集数据,并对数据进行质性分析以说明问题。研究结果表明:在协作任务中,图示方式与工具可以直观明了地呈现内容,并能辅助沟通,缓解学习者认知负荷。其具体表现形式和功用与学习任务、环境与条件有关。初步结论是:图示方式与工具可以通过平衡工作记忆、聚焦思考,促进理解与认知并辅助表达;在协作沟通中,图示工具的使用扩展了沟通方式,有助于提高沟通效果。
[Abstract]:How to design and use information technology to improve learning performance has been the focus of digital learning research. From the perspective of learning science, the team tries to enhance the learning mode supported by information technology and improve the effect of digital learning by exploring the graphic mode and designing and developing the graphic technology. In theory, in computer-supported collaborative learning with more complex cognitive tasks, semantic diagrams have the potential to ease the cognitive burden and provide support for collaborative tasks. This paper attempts to explore the effectiveness of the graphical method and tool used in distance collaborative learning as a visualization technique in order to understand the characteristics of the use of graphical tools in the process of collaborative learning and to explore the potential of the graphical methods and tools in collaborative learning. Through literature and theoretical research, this paper puts forward the hypothesis, adopts the design and research method of intervening natural teaching situation, applies the graphic tools and methods to the collaborative task design, collects the data through observation and interview. And the qualitative analysis of the data to explain the problem. The results show that in the collaborative task, the graphical method and the tools can present the content intuitively and clearly, and can help to communicate and relieve the learners' cognitive load. Its concrete manifestation and function are related to learning task, environment and condition. The preliminary conclusion is that the graphical method and tools can balance working memory, focus on thinking, promote understanding and cognition, and assist expression. In cooperative communication, the use of graphical tools expands the communication mode and helps to improve the communication effect.
