This article explores the concept of community of enquiry through an examination of 3 case studies: (a) a school-based community of enquiry involving pupils, teachers, and researchers; (b) a community of enquiry involving teachers from around 100 different schools in a Scottish local authority, together with policy advisers and researchers; and (c) the project team involved in the present study itself. The 3 case studies are considered in relation to 7 factors identified in previous research as significant considerations when attempting to build a community of enquiry, namely: dialogue and participation; relationships; perspectives and assumptions; structure and context; climate; purpose; and control. The authors conclude by highlighting key issues and potential implications for attempts to foster collaborative partnerships between educational researchers and practitioners. (Contains 1 figure.)
