Broadening participation starts by examining our own practices. The Center for Advancement of Informal Science Education (CAISE) Broadening Participation in STEM task force offers a Conversation Guide that outlines key challenges, questions, and tips to facilitate conversation.
CAISE also offers a Toolkit: Broadening Perspectives on Broadening Participation in STEM to support strategic efforts to broaden participation in STEM. Use the resources to plan and lead reflective discussions about current practices, with an eye to developing goals, strategies, and priorities that can make your work more inclusive.
Check out CAISE news and the many other resources they provide to support research, evaluation, and proposal writing.
