Learning from interactive learning environments enriched with multiple external representations (MERs) is often beneficial. The learning benefits of MERs highly rely on the development of Representational Competence. Representational Competence refers to an ability to translate and see relations between MERs. The relevant research findings have consistently reported learners' difficulty in relating and translating in MERs due to insufficient development of Representational Competence. Although dynamic linking is one of the strategies recommended to address this issue, it offers mixed results. This paper reports design of a new interaction feature that overcomes some of the limitations of traditional dynamically linked representations. We designed an additional interaction in dynamically linked MERs to support learners' cognitive demands; we refer to this as . The goal of this additional affordance was to strengthen learners' cross-representation cognitive linkage by promoting Representational Competence. The paper reports the study conducted to investigate effects of Reciprocative Dynamic Linking on students' Representational Competence. The said study was conducted in a course on Signals and Systems from Electrical Engineering program ( = 24). The subjects were assigned to two conditions: a Simulation and a Simulation with Reciprocative Dynamic Linking. The representation competence was assessed with an instrument for measuring Representational Competence within Signals and Systems domain. The effect of Reciprocative Dynamic Linking on learners' cognitive load was also investigated. The results confirmed that Reciprocative Dynamic Linking could lead to improvement in Representational Competence and thus, higher learning for "Apply and Analyze Procedural knowledge" categories of tasks. Reciprocative Dynamic Linking also promoted germane cognitive load of learners, as it could offer the required cognitive support to improve learners' Representational Competence. The findings from semi-structured interviews and screen capture analysis corroborated the results. This paper provides details of how to design Reciprocative Dynamic Linking in interactive learning environments and its effect on learners' Representational Competence. Apart from establishing learning effectiveness of Reciprocative Dynamic Linking, the study further contributes by confirming the role of cognitive processing of learners while learning from interactive learning environments. The findings from the study suggest designing strategies not for just creating highly interactive learning environments but equipping a given learning environment with conducive interaction features that foster learning.
从富含多种外部表征(MERs)的交互式学习环境中学习通常是有益的。MERs的学习益处高度依赖于表征能力的发展。表征能力指的是翻译和洞察MERs之间关系的能力。相关研究结果一直报告称,由于表征能力发展不足,学习者在关联和翻译MERs方面存在困难。尽管动态链接是推荐用于解决此问题的策略之一,但其效果参差不齐。本文报告了一种新交互功能的设计,该功能克服了传统动态链接表征的一些局限性。我们在动态链接的MERs中设计了一种额外的交互方式来支持学习者的认知需求;我们将其称为“往复动态链接”。这种额外功能的目标是通过提升表征能力来加强学习者的跨表征认知联系。本文报告了为研究往复动态链接对学生表征能力的影响而进行的研究。上述研究在电气工程专业的信号与系统课程中开展(n = 24)。受试者被分配到两种条件下:一种是模拟条件,另一种是带有往复动态链接的模拟条件。使用一种用于测量信号与系统领域表征能力的工具来评估表征能力。还研究了往复动态链接对学习者认知负荷的影响。结果证实,往复动态链接可导致表征能力的提升,从而在“应用和分析程序性知识”任务类别中实现更高水平的学习。往复动态链接还促进了学习者的相关认知负荷,因为它可以提供所需的认知支持来提高学习者的表征能力。半结构化访谈和屏幕截图分析的结果证实了这些结果。本文详细介绍了如何在交互式学习环境中设计往复动态链接及其对学习者表征能力的影响。除了确立往复动态链接的学习效果外,该研究还通过确认学习者在从交互式学习环境中学习时的认知加工作用做出了进一步贡献。该研究的结果表明,设计策略不应仅仅是创建高度交互式的学习环境,而是要为特定的学习环境配备有助于促进学习的交互功能。
