This community-based research project seeks to identify priorities and interventions to combat high classroom temperatures in three vulnerable Montreal neighborhoods: Montreal-Nord, Parc-Ex, and Hochelaga Maisonneuve. The project will mobilize diverse local actors through the creation of community research boards (CRBs) in each neighborhood, composed of 10-15 members, including leaders, community organizations, school representatives, and residents. The project will follow a Human-Centered Design (HCD) process with CRBs leading three main phases: 1) Exploratory Workshops: CRBs will identify community priorities and knowledge gaps by reviewing existing data on heat-related impacts. 2) Research Prioritization: CRBs will determine research priorities and activities using ideation strategies and insights from focus group discussions. 3) Strategic Planning: CRBs will develop final proposals for research implementation, addressing recruitment, communication strategies, and potential barriers. This project will empower communities to identify local priorities and gaps in heat-related climate change research in school settings, fostering climate resilience and justice. Collaborating with local partners, these communities will develop and test interventions in future climate change projects.
