Abstract
This study of 723 college students seeks to assess the adequacy of the Community of Inquiry (CoI) framework for describing and explaining differences in learning outcomes in hybrid and fully online learning environments. Hypothesizing that the CoI model's theoretical constructs of presence reflect educational effectiveness in a variety of environments, this article seeks evidence of whether students in varying learning environments are likely to rank them differently with regard to teaching, social, and cognitive presence. The study utilizes factor-, hierarchical-regression-, and path analyses to determine the validity of the CoI constructs as well as to characterize the nature of relationships between them. Results suggest that the model is coherent and accounts for the small but significant differences recently reported in the literature regarding the superiority of hybrid environments relative to fully online environments (Means, B., Toyama, Y., Murphy, R., Bakia, M., & Jones, K. (2009). Evaluation of evidence-based practices in online learning: A meta-analysis and review of online learning studies.
