Since 1992, the Montréal Biodôme has operated representations of five ecosystems in order to exhibit living organisms in all their complexity and interconnections. Its mission is to “raise individual and collective awareness about the need to get involved in protecting natural ecosystems.” The institution’s Public Programs and Education Department is examining a method for improving how activities fulfill this mission more tangibly. This paper outlines the process involved. In essence, it proposes a new educational approach based on a model developed within the Biodôme itself—the “pyramid of intervention”—which calls on visitors to move toward taking action. The paper also presents the primary challenges involved in implementing such an approach, along with the measures put in place to do so.
