For the past year, I have been fortunate to be involved in an NSF-funded endeavor to identify and articulate grand challenges driving geoscience education research in the years to come. The resulting product is a community framework for geoscience education research, which is freely-accessible to anyone with interests in this domain. I served on a working group for one of the 10 strands focused on teaching about the Earth in the context of societal issues, a summary of which can be found in published form here.

Many thanks to Kristen St. John and the other PIs for leading this effort!
