SL-CN: Project LENS: Leveraging Expertise in Neurotechnologies to Study Individual Differences in Multimedia Learning

在STEM教育中使用多媒体正在经历显着的增长。这种增长是如此之快，以至于它远远超过了研究能力，以跟上其应用。 透镜项目旨在建立一个学习科学合作网络（SL-CN），由佛罗里达大学的教育神经科学实验室和情绪与注意力研究中心、马萨诸塞州波士顿大学的视觉学习实验室和华盛顿州立大学的教育神经心理学实验室组成。该网络汇集了来自以下学科的学者：STEM教育，认知和发展心理学，神经科学，教育技术，计算机科学和教育测量。来自透镜项目网络的专家将采用新的方法和神经成像技术来研究多媒体学习，以解决该领域知识发展的差距。这个合作网络的目的是利用每个节点的优势，利用认知神经技术（脑电图，功能性近红外光谱和眼动跟踪）的专业知识，以实现严格的跨学科研究生态系统。透镜项目将通过综合神经认知、概念和经验方法推进关于学习的基础研究。这个跨学科的研究团队将从以下几个方面推动学习科学的发展：1）现有的多媒体学习研究大多集中在认知负荷和学习上，而没有太多地考虑学习者的个体特征，这些研究者提出了一个范式转变，将学习者的多样性和他们的个体差异置于多媒体学习研究的中心; 2）虽然现有的少数使用个体差异范式的研究主要集中在工作记忆容量的作用上，但该项目采取了更广泛的方法，在更精确的水平上研究个体差异，探索注意力和认知变量的作用，例如视觉注意广度，抑制控制等。3）本项目所采用的综合性、跨学科的研究方法将减少教育研究者？在注意力、认知和学习的研究中依赖自我报告，并促进使用相关的认知神经科学框架和工具来改进学习科学; 4）关于个体差异的累积数据将为构建可用于个性化和适应多媒体学习的综合计算模型奠定重要基础。除了推进设计多媒体学习的理解，网络的网络研讨会，嘉宾演讲和研究生的复合辅导将提高学习，教学和学生的成就内和跨我们的网络节点。该项目将通过关注具有广泛人口统计学，注意力和认知差异的多样化社区大学生群体，以及通过从目前在STEM中代表性不足的群体中招募研究助理来扩大代表性不足的群体的参与。透镜项目的目的是加强研究和教育的基础设施，这将通过建立学习科学方面的合作和伙伴关系来实现。 透镜项目至少涉及三项国家倡议：a）BRAIN倡议（2014年），B）美国毕业倡议（2015年）和c）美国众议院关于阅读障碍的决议（第113届国会第456号决议）。

The use of multimedia in STEM education is undergoing a remarkable growth. Such growth has been so rapid that it has far outstripped the abilities of research to keep pace with its application. Project LENS is designed to establish a Science of Learning Collaborative Network (SL-CN) consisting of the Educational Neuroscience Laboratory and Center for the Study of Emotion and Attention at the University of Florida, the Laboratory for Visual Learning at the University of Massachusetts Boston, and the Educational Neuropsychology Laboratory at Washington State University. The network brings together scholars from the following disciplines: STEM Education, Cognitive and Developmental Psychology, Neuroscience, Educational Technology, Computer Science, and Educational Measurement. Experts from the Project LENS network will employ novel methods and neuroimaging technologies to investigate multimedia learning in order to address the gap in knowledge developing in this field. The purpose of this collaborative network is to capitalize on the strengths of each node leveraging expertise in cognitive neurotechnologies (Electroencephalography, functional Near Infrared Spectroscopy, and eye tracking) to enable a rigorous interdisciplinary research ecosystem. Project LENS will advance fundamental research about learning through integrative neurocognitive conceptual and empirical approaches. This interdisciplinary team will advance the science of learning in several ways, including: 1) While most existing multimedia learning research focuses on cognitive load and learning without much consideration of individual learner characteristics, these investigators propose a paradigm shift to put the diversity of learners and their individual differences in the center of multimedia learning research; 2) While the few existing studies that use the individual differences paradigm focus primarily on the role of working memory capacity, this project takes a broader approach and study individual differences at a more precise level, exploring the role of such attentional and cognitive variables as visual attention span, inhibitory control etc. 3) The integrative and interdisciplinary research approaches used in this project will reduce educational researchers? reliance on self-reports in the study of attention, cognition and learning and promote the use of relevant cognitive neuroscience frameworks and tools to improve the science of learning; and 4) the accumulated data on individual differences will lay important groundwork for the construction of comprehensive computational models that can be used to personalize and adapt multimedia learning. In addition to advancing the understanding of designing multimedia learning, the network's webinars, guest presentations, and composite mentorship of graduate students will enhance learning, teaching, and student advisement within and across our network nodes. The project will broaden participation of underrepresented groups by focusing on the diverse community college student population with a wide range of demographic, attentional, and cognitive differences, and by recruiting research assistants from groups that are currently underrepresented in STEM. The purpose of Project LENS is to enhance infrastructure for research and education, which would be accomplished by establishing collaborations and partnerships in the science of learning. Project LENS addresses at least three national initiatives: a) the BRAIN initiative (2014), b) American Graduation Initiative (2015), and c) US House Resolution on Dyslexia (#456, 113th Congress).
