Informal Science (formerly the Center for the Advancement of Informal Science Education) has released a new toolkit: Broadening Perspectives on Broadening Participation in STEM. Key practice briefs, such as these on Cultural Norms of STEM and Modeling Workplace Inclusion serve as discussion-starters for identifying the issues and solutions for each site.
Find information on this and many other resources for increasing inclusion in ecology on the diversity resources page of the LTER Network web site.
