This is a research study of design and engineering classes that use a problem-based learning (PBL) approach in digital fabrication makerspaces in two middle schools. In these studies, teachers employ a PBL approach and provide an ill-structured problem scenario to facilitate design and engineering lessons in the FabLab (fabrication laboratory).…

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…

In this work, we sought to understand ways that students experienced a small-scale portfolio assignment provided to them as an opportunity reflect on their experiences in a project-based class. This work was motivated by research in various instructional contexts showing that portfolio construction results in important learning outcomes. We wanted…
