The conceptual and theoretical models presented in this document were developed over a roughly twelve-year period, starting in 2005, by the Chair (Paul R. Carr, Université du Québec en Outaouais) and Co-Chair (Gina Thésée, Université du Québec à Montréal) of the UNESCO Chair DCMÉT. These models have been published in diverse academic journals in either English or French, and have been translated and adapted herein to produce an updated and bilingual representation of the Education for Democracy research that Carr and Thésée have produced. In some cases, the models have been refined (and improved) over time, and they are presented as a means of attempting to elucidate, interrogate and highlight the meaning of the three themes that underpin the UNESCO Chair DCMÉT.
