"Supporting LGBTQ-Inclusive Teaching," the first report of its kind to examine the possibilities inherent in LGBTQ-inclusive materials for training classroom teachers, explores the biggest challenges to creating, implementing, and scaling up this kind of PreK-12 teacher professional learning. It is also the first to consider the opportunities in harnessing digital materials, particularly open educational resources (OER), as tools for helping to overcome those challenges and enabling queer inclusion. Situated within the broader context of culturally responsive teaching (CRT), this report aims to help set a research and practice agenda for education leaders that envisions ways to combine lessons learned from both the LGBTQ advocacy and open education fields.
