The goal of this planning grant, which is based on the Cultural-Historical Activity Theory (CHAT). is to explicitly focus on broadening participation in the K-12 STEM teaching workforce, with the theory of action that diversifying the K-12 STEM teaching workforce would in the long term help more students see STEM as accessible to them and then be more likely to choose a STEM degree or career. This grant is also funded by NSF INCLUDES.

This Early-Stage Design and Development project is developing NGSS-friendly middle school curriculum units on Heredity and Evolution that build skills in constructing explanations and understanding of cause and effect and include embedded formative and summative assessment measures. We will conduct an in-depth study to elucidate how 3D learning contributes to students' conceptual understanding of heredity and evolution, and the supports middle school teachers need to enact 3D curricula and support their students.

To lower the barriers in STEM disciplines for students, using evidence-based research, we designed and conducted a professional development program that built middle school teachers' capacity to use hands-on robotics and engineering design as the curriculum focus. Through summer workshops, teachers learned to: build and program LEGO robots; create and implement standards-aligned robotics-based STEM lessons; and develop, practice, and examine optimal pedagogical approaches for STEM learning using robotics.
