A mathematician and a STEM education researcher use 3-D printing to teach Calculus 3 and see how it may change students’ attitudes towards math. The majority of students in Calculus 3—multivariable calculus with technology—are not math majors. They are mechanical engineers, civil engineers, biologists, computer scientists. And those are people we want to make sure do their calculations correctly. The two-dimensional and three-dimensional calculus they learn in calc 3 helps them assess everything from water flowing through a dam, to heat transfer in materials, to the mechanical stress on a gear.
