This paper focuses on the K-12 educational activities of COSMOS-<u>C</u>loud enhanced <u>O</u>pen <u>S</u>oftware defined <u>MO</u>bile wireless testbed for city-<u>S</u>cale deployment. The COSMOS wireless reasearch testbed is being deployed in West Harlem (New York City) as part of the NSF Platforms for Advanced Wireless Research (PAWR) program. COSMOS' approach for K-12 education is twofold: (i) create an innovative and concrete set of methods/tools that allow teaching STEM subjects using live experiments related to wireless networks/IoT/cloud, and (ii) enhance the professional development (PD) of K-12 teachers and collaborate with them to create hands-on educational material for the students. The COSMOS team has already conducted successful pilot summer programs for middle and high school STEM teachers, where the team worked with the teachers and jointly developed innovative real-world experiments that were organized as automated and repeatable math, science, and computer science labs to be used in the classroom. The labs run on the COSMOS Educational Toolkit, a hardware and software system that offers a large variety of pre-orchestrated K-12 educational labs. The software executes and manages the experiments in the same operational philosophy as the COSMOS testbed. Specifically, since it is designed for use by non-technical middle and high school teachers/students, it adds easy-to-use enhancements to the experiments' execution and the results visualization. The labs are also supported by Next Generation Science Standards (NGSS)-compliant teacher/student material. This paper describes the teachers' PD program, the NGSS lessons created and the hardware and software system developed to support the initiative. Additionally, it provides an evaluation of the PD approach as well as the expected impact to K-12 STEM education. Current limitations and future work are also included as part of the discussion section.

COSMOS 教育工具包

本文重点介绍COSMOS-<u>C</u>大声增强<u>O</u>pen<u>S</u>软件定义<u>MO</u>的K-12教育活动用于城市-<u>S</u>cale 部署的胆汁无线测试平台。作为 NSF 高级无线研究平台 (PAWR) 计划的一部分，COSMOS 无线研究测试平台正在西哈莱姆（纽约市）部署。COSMOS 对 K-12 教育的方法是双重的：（i）创建一套创新和具体的方法/工具，允许使用与无线网络/物联网/云相关的现场实验教授 STEM 科目，以及（ii）促进专业发展（ PD) 的 K-12 教师，并与他们合作为学生创建动手实践的教育材料。COSMOS 团队已经成功地为初中和高中 STEM 教师开展了试点暑期项目，团队与教师合作，共同开发了创新的现实世界实验，这些实验被组织为自动化和可重复的数学、科学和计算机科学实验室在课堂上使用。这些实验室在 COSMOS 教育工具包上运行，这是一个硬件和软件系统，可提供大量预先编排的 K-12 教育实验室。该软件以与 COSMOS 测试平台相同的操作理念执行和管理实验。具体来说，由于它是为非技术性的初中和高中教师/学生设计的，它为实验的执行和结果的可视化增加了易于使用的增强功能。这些实验室还得到符合下一代科学标准 (NGSS) 的教师/学生材料的支持。本文介绍了教师的 PD 计划、创建的 NGSS 课程以及为支持该计划而开发的硬件和软件系统。此外，它还评估了 PD 方法以及对 K-12 STEM 教育的预期影响。当前的限制和未来的工作也包括在讨论部分。
