This is the third part in a series of guidebooks focused on understand and applying the CSCCE Community Participation Model. In this section, we focus on the role of scaffolding to support and grow inclusive communities in STEM. In part one of the CSCCE Community Participation Model (CPM) guidebook, we outlined our model for describing member engagement in STEM communities - the domain on which CSCCE focuses. And in part two, we focused on the role of community champions, emergent leaders who take on additional roles within the community to ensure its maintenance, growth, and evolution. About CSCCE The Center for Scientific Collaboration and Community Engagement (CSCCE) champions the importance of human infrastructure for effective collaboration in STEM. We provide training and support for the people who make scientific collaborations succeed at scale - and we also research the impact of these emerging roles.
