We designed a "3D Printing Technology Science Project" as part of a science methods course to engage preservice teachers (N = 41) in a 3D printing project that they could implement with their future elementary school students. The goal was to introduce prospective teachers to engineering design and technology application ideas and…

This analysis draws on X hours of video data collected of elementary-aged children (n = 4) during a 14-day…
