EDU: Collaborative: When Cyber Security Meets Physical World: A Multimedia-based Virtual Classroom for Cyber-Physical Systems Security Education to Serve City / Rural Colleges

本项目建立了一个基于多媒体的虚拟教室，并配有虚拟实验室助教，用于网络物理系统(CPS)的安全教育。这样的虚拟教室帮助资源有限的农村地区的大学生通过与更大学校的其他学生在线点对点学习环境来学习最新的CPS安全知识。该项目包括三个新的贡献：(1)所有学习材料都采用应用程序驱动的学习方法，将医疗保健、可再生能源和工业控制等不同领域的示例用作CPS攻击分析的基础；(2)在多媒体公司的帮助下，该项目正在构建有趣的虚拟课堂讲座；以及(3)为了满足开放访问实验室的要求，该项目正在构建交互式虚拟实验室助手软件，使远程学生能够使用多媒体工具进行虚拟硬件实验室实验并获得帮助。设计在几个方面鼓励创新学习：发达的实验室需要一个带有创意孵化的迭代过程，以迫使学生遵循更成熟的创造性设计过程；所有实验室故意包含一些模棱两可的内容，以鼓励对单个问题寻求多个答案；所有CPS安全实验室/项目都采用基于3E(解释-利用-探索)的教学法。基础水平实验室强调概念解释。中级高级项目要求学生利用以前的知识来执行多学科的CPS安全任务。高级实验室需要独立探索，才能找到创造性的解决方案。由此产生的教学方法可以推广到其他农村大学，该项目使用了一个积极主动的传播计划来实现这一目标。

This project establishes a multimedia-based virtual classroom with a virtual lab teaching assistant for the education of cyber physical system (CPS) security. Such a virtual classroom helps college students in resource-limited rural areas to learn the latest CPS security knowledge via an on-line peer-to-peer learning environment with other students from larger schools. This project includes three novel contributions: (1) all learning materials embrace an application-driven learning approach, with examples from diverse areas such as healthcare, renewable energy, and industrial controls used as the basis for CPS attack analysis; (2) with the help of a multimedia company, the project is building interesting virtual classroom lectures; and (3) to meet the open access lab requirements, the project is building interactive virtual lab helper software to enable remote students to conduct virtual hardware lab experiments and obtain help using multimedia tools. The design encourages innovative learning in several ways: developed labs require an iterative process with idea incubation to force students to follow a more mature creative design process; all labs intentionally include some ambiguity to encourage the search for multiple answers to a single problem; and the 3E (Explain-Exploit-Explore) based pedagogy is adopted for all CPS security labs/projects. The basic level labs emphasize concept explanations. The intermediate level senior projects require students to exploit previous knowledge to perform a multidisciplinary CPS security task. The advanced-level labs require independent exploration to reach creative solutions. The resulting teaching methodologies can be extended to other rural colleges and this project uses a proactive dissemination plan to achieve this aim.
