POSE: Phase I: Establishing an Ecosystem for Open-source Educational Computer Aided Design (CAD) Models

该项目由开放源代码生态系统之路（POSE）资助，旨在利用开放源代码开发的力量，为国家和社会重要问题创造新的技术解决方案。在过去的十年中，许多K-12学校已经建立了具有三维（3D）打印机，数字模切机和其他制造工具的创客空间。为了促进学校创客空间的有效利用，正在开发一个开源生态系统，为学生和教育工作者提供精心策划、经过仔细审查的计算机辅助设计（CAD）模型。该生态系统将围绕现有的开源教育CAD模型库构建。长期生态系统包括一个CAD模型交换中心，其中包含（a）描述课堂使用的同行评审文章，以及（B）链接到存储库中相关可下载文件的模型。被接受的基于装配的文章将发表在一个新的杂志，教育制造设计（艾德F），建立作为生态系统的一个组成部分。该项目的新奇在于，教育CAD模型将在添加到存储库之前进行外部审查，测试和验证。K-12创客空间中广泛使用的设计和制造工具为创造新的物体和重新混合现有设计提供了可能。科学，数学和工程教育工作者和他们的学生将受益于获得精心策划的模型和相关的教学材料。由此产生的开源生态系统的影响将增加K-12创客空间在所有相关学科的有效利用，并导致更广泛的设计和制造素养。在该项目为期一年的范围界定活动中，国际技术与工程教育协会（ITEEA）将修订其旗舰课程，设计工程（EbD © ITEEA），以整合围绕CAD模型存储库构建的生态系统。使用该课程的5，000多名教师和50，000多名学生可以参与作为修订课程的关键要素整合的模型。此外，通过马萨诸塞州理工学院（MIT）的原子和比特中心建立的Fab基金会将合作让2,000个制造实验室（FabLabs）参与这一过程。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project is funded by Pathways to Enable Open-Source Ecosystems (POSE) which seeks to harness the power of open-source development for the creation of new technology solutions to problems of national and societal importance. During the past decade, many K-12 schools have established makerspaces with three dimensional (3D) printers, digital die cutters, and other fabrication tools. To facilitate effective use of school makerspaces, an open-source ecosystem is being developed to provide students and educators with curated, carefully reviewed Computer-Aided Design (CAD) models. The ecosystem will be structured around an existing open-source Educational CAD Model Repository. The long-term ecosystem includes a clearinghouse for CAD models with (a) peer-reviewed articles describing classroom use, and (b) the models linked to associated downloadable files in the repository. Accepted practitioner-based articles will be published in a new journal, Educational Fabrication & Design (ED&F), established as one component of the ecosystem. The project’s novelty is that educational CAD models will be externally reviewed, tested, and validated before they are added to the repository. The widespread availability of design and fabrication tools in K-12 makerspaces offers the potential to create new objects and remix existing designs. Science, mathematics, and engineering educators and their students will benefit from access to carefully curated models and associated instructional materials. The resulting open-source ecosystem’s impact will increase effective use of K-12 makerspaces across all of the relevant disciplines and lead to broader literacy in design and fabrication.During the one year scoping activities of this project, the International Technology and Engineering Education Association (ITEEA) will revise its flagship curriculum, Engineering by Design (EbD © ITEEA), to incorporate the ecosystem constructed around the repository of CAD models. More than 5,000 teachers and more than 50,000 students using the curriculum can engage with the models integrated as a keystone element of the revised curriculum. In addition, the Fab Foundation, established through the Center for Atoms and Bits at the Massachusetts Institute of Technology (MIT), will collaborate to engage a network of 2,000 Fabrication Laboratories (FabLabs) in this process. The eduFAB Network, an educational extension of the Fab Foundation, will work to coordinate activities across the respective disciplines.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
