The interdisciplinary approach that science, technology, engineering and mathematics (STEM) projects inspire in both teachers and students "brings to light a larger picture that promotes real-world scientific applications, which has in turn been shown to increase undergraduate persistence in STEM." The high school students have been warned repeatedly that they must prepare themselves for jobs and career fields that may not yet even exist. These warnings have resulted in an increased emphasis on cooperative problem solving, innovative solution writing, and technological skill acquisition across the curricula of secondary schools. By pairing mathematics and technology classes together in unique ways, students can see firsthand what those futuristic jobs may demand. At Unionville High School in Kennett Square, PA, calculus teacher Dori Ray requires her advanced placement calculus students to build three-dimensional solids of known cross-section out of layers of hand-cut foam. The process is very similar to the process technology and engineering teachers have used for years to make 3-D models from sheet goods using laser cutters, vinyl sign cutters, CNC routers, and manual processes. These activities allowed the calculus students to be exposed to engineering applications of a classic calculus problem. (Contains 7 figures.)
