STEM integration: solids, CAD, and 3D printers

摘要

During a rigorous session analyzing graphs of curves and lines that would help 11th and 12th grade calculus students determine the volume of solids, I could see that they were becoming less and less engaged. With more than a little frustration they asked, "What is the point of knowing the volume of something like this? I've never seen shapes like this in real life."They were grasping the basic theoretical concepts well enough, but it turns out that finding relevancy was more elusive.
