Learning to Struggle: Supporting Middle-grade Teachers' Understanding of Productive Struggle in STEM Teaching and Learning.

This qualitative study examines the influence of a 3-year professional development project for middle school mathematics, science, and special education teachers focused on integrating science, mathematics, and engineering in classroom instruction on participants' understandings of productive struggle in learning. Multi-disciplinary teams of teachers engaged as learners to use engineering design as a framework for integrating significant mathematics and science content supported by effective teaching practices. In this paper, we describe how the components of our professional development design supported teacher-participants to make sense of productive struggle in learning.

Taking Professional Development From 2D to 3D: Design-Based Learning, 2D Modeling, and 3D Fabrication for Authentic Standards-Aligned Lesson Plans.

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 the real world using printed parts.
