There is currently significant interest in 3D fabrication in middle school classrooms. At its best 3D printing can be utilized in authentic design projects that integrate math, science, and technology, which facilitate deep learning by students. In essence, students are able to tinker in a virtual world using 3D design software and then tinker in the real world using printed parts. We describe a professional development activity we designed to enable middle school teachers who had taken part in a three-year Math Science Partnership program to authentically integrate 3D printing into design-based lessons. We include some examples of successful design-based lesson plans.

从2D到3D进行专业开发：基于设计的学习，2D建模和3D构造，可实现真正的符合标准的教学计划。

当前，人们对中学教室中的3D制作非常感兴趣。在最佳状态下，可以将3D打印用于结合数学，科学和技术的真实设计项目中，从而促进学生的深度学习。从本质上讲，学生可以使用3D设计软件在虚拟世界中进行修补，然后使用印刷零件在现实世界中进行修补。我们描述了一项旨在帮助参加三年数学科学合作伙伴计划的中学教师将3D打印真正整合到基于设计的课程中的专业发展活动。我们提供了一些成功的基于设计的课程计划的示例。
