The geoscience education research (GER) community has produced a collaborative research framework that summarizes guiding questions for future research to inform and improve undergraduate geoscience teaching and learning. The GER Framework (St. John [Ed.], 2018a) was developed through an iterative process involving multiple stages of community input. In total, approximately 200 geoscience educators and researchers contributed to this project in one or more of the following capacities: as authors, reviewers, survey respondents, workshop participants, webinar participants, town hall participants, and/or focus group participants. Review of survey data, reports, publications, and discussions resulted in a set of guiding questions and research strategies for ten research areas where individual researchers can make important contributions. While presented as distinct research areas, the ten themes have numerous cross-theme opportunities that integrate content areas, skills, and types of students. Cross-theme recommendations regarding strategies for future research are described here, along with suggested synergies with other national efforts in geoscience and STEM education.
