Genes, Traits & Change over Time was produced by the Genetic Science Learning Center (GSLC) in collaboration with middle school teachers from across the US. The unit went through multiple rounds of development, revision, and refinement. These were informed by teacher feedback and student assessment measures.

This work was supported by an award from the National Science Foundation, grant #1814194.
