Given the critical importance of undergraduate STEM education to prepare the next generation workforce, universities must continuously research and implement enhancements to the undergraduate STEM curriculum and pedagogy to meet technological and societal needs and to help faculty educate and motivate their students. This project brings together experts from different spheres to meld innovative research in wireless communications, visual analytics, and game-based learning (also known as "gamification") for authentic, transformative STEM learning. The project builds on a foundation of knowledge related to visualization, gamification, and virtual and remote laboratory experiences, and their use in achieving instructional outcomes. The project will merge the ideas of radio resources and dynamic spectrum management with cutting edge visualization tools to transform the students' engagement in the learning process. The implementation will enable students in Electrical and Computer Engineering to visualize and understand radio frequency environments and behavior of spectrum managers, human operators and autonomous radios. For example, students will be able to discover from first-hand experience the existence of the Nash equilibrium in certain scenarios involving the coexistence of multiple self-interested autonomous radios. The project will take advantage of Virginia Tech's Cognitive Radio and Network (CORNET) testbed that allows students to operate radios in a safe environment to provide a strong sense of realism, combined with space to experiment and fail. The project will contribute to the research literature on effectiveness of visualization and gamification techniques for enabling deep understanding of abstract and not normally perceptible STEM concepts and phenomena. Student learning will be assessed using both in-class measures administered by the instructors and external, qualitative evaluation using surveys, reflective essays, and focus groups. In addition, access to a novel hands-on experimental tool will make concepts in Electrical and Computer Engineering accessible to more students.

鉴于本科 STEM 教育对于培养下一代劳动力至关重要，大学必须不断研究和改进本科 STEM 课程和教学法，以满足技术和社会需求，并帮助教师教育和激励学生。该项目汇集了来自不同领域的专家，融合无线通信、视觉分析和基于游戏的学习（也称为“游戏化”）方面的创新研究，以实现真实、变革性的 STEM 学习。该项目建立在与可视化、游戏化、虚拟和远程实验室体验及其在实现教学成果中的应用相关的知识基础上。该项目将无线电资源和动态频谱管理的理念与尖端的可视化工具相结合，以改变学生对学习过程的参与。该实施将使电气和计算机工程专业的学生能够可视化并理解射频环境以及频谱管理者、操作员和自主无线电的行为。 例如，学生将能够从第一手经验中发现在涉及多个自利自主无线电共存的某些场景中纳什均衡的存在。该项目将利用弗吉尼亚理工大学的认知无线电和网络（CORNET）测试平台，让学生在安全的环境中操作无线电，提供强烈的现实感，并提供实验和失败的空间。该项目将为有关可视化和游戏化技术有效性的研究文献做出贡献，以帮助深入理解抽象且通常不可感知的 STEM 概念和现象。学生的学习将通过教师管理的课堂测量和通过调查、反思性文章和焦点小组进行的外部定性评估进行评估。 此外，获得新颖的实践实验工具将使更多学生能够接触到电气和计算机工程的概念。
