Educational Interventions That Improve Environmental Behaviors: A Meta-Analysis

Abstract In this meta-analysis the author compared the effectiveness of educational interventions (N = 18) conducted in classrooms and in nontraditional settings in improving environmental behavior. Classroom interventions improved environmental behavior more effectively (r = .65) than interventions in nontraditional settings (r = .27). Interventions that most effectively improved environmental behavior actively involved participants and used young participants. Active participation was more likely in interventions implemented in classrooms than in nontraditional settings. However, few of these studies measured actual behavior, and often poor research methods were used.
