The focus of this chapter is an exploration of the intersection between widely acknowledged and implemented research-based practices for effective PD and a conceptual framework for effective online learning and engagement called the Community of Inquiry (CoI) (Garrision, Anderson, & Archer, 2000). A social constructivist perspective is used to align the characteristics of effective PD (e.g., duration, collaborative participation, active learning, coherence, and content focus) with the three CoI presences (e.g., teaching, social, and cognitive presences). Beyond the alignment of these two conceptual frameworks, practical examples of online tools are discussed for both synchronous and asynchronous online learning contexts within this chapter.
