3 Garrison et al. (2000) Summary of the Community of Inquiry (COI) Theory 1. The heart of higher education is collaborative critical inquiry to build and apply discipline knowledge to relevant issues and problems. 2. Asynchronous discussion is an ideal medium for collaborative critical inquiry because it affords full participation in discussion and time for reflection between messages. 3. Collaborative critical inquiry requires the social presence of all participants to support open communication and group cohesion. 4. Collaborative critical inquiry requires the cognitive presence of all participants in a process of problem recognition, exploration, integration, and resolution. 5. Collaborative critical inquiry requires a teaching presence to foster and guide the social and cognitive presence of participants. 3

4 Detailed Elements of the Community of Inquiry Theory Social presence Open and effective communication Group cohesion Projecting oneself socially and emotionally as a real person Exchanging and critically examining information and ideas Working collaboratively toward a common goal Garrison, Anderson, & Archer (2000) See for tips on creating social presence. Cognitive presence Trigger event Exploration phase Integration phase Resolution phase Engagement in critical inquiry through sustained reflection and discourse Identifying or recognizing an issue or problem Examining all aspects of the problem; gathering information; considering knowledge that may be relevant Making sense of data and ideas generated; constructing meaning (new knowledge); identifying potential solutions Building consensus for one solution Involves many aspects of critical and creative thinking Analysis Knowledge transfer; questioning assumptions; brainstorming; creative insights; diverse perspectives; citation Analysis; synthesis; inductive and deductive reasoning Evaluation; informed judgment; warrants and argument; hypothetical reasoning Garrison, Anderson, & Archer (2001) Teaching presence Design Facilitating discourse and direct instruction Management of social and cognitive processes to obtain learning outcomes Planning learning activities and preparing support materials Supporting and guiding the learning process as it happens Garrison (2007) 4

5 Principles for Practice Design Strategies Assign authentic, meaningful, open-ended issues or problems to resolve. (Bain, 2004; Fink, 2003; Garrison, 2007) Prepare students for critical inquiry and collaboration by defining and explaining value. (Garrison, 2007; Palloff & Pratt, 2005) Structure the collaborative inquiry process with clear directions, rubrics, and examples. (Garrison, 2007; Palloff & Pratt, 2005) Facilitation Strategies Insert feedback messages that let students know when they are on or off track relative to the inquiry process (Ambrose et al., 2010) Insert direct instruction messages to aid/reinforce key content understanding. (Garrison, 2007) Use questions to promote deeper inquiry and critical thinking: o Clarification questions prompt better understanding of the problem and related ideas. o o o Evidence questions prompt informed thinking. Linking questions prompt construction of meaning. Hypothetical and cause-and-effect questions prompt virtual testing of ideas. o Summary and synthesis questions prompt consensus and conclusions. (Brookfield, 2005) Insert messages early enough in the process to change behavior. (Ambrose et al., 2010) Model good critical inquiry and social presence practices in your messages. (Palloff & Pratt, 2005) 5

The Journal of Educators Online, 6(1). A comparison of online courses with discussion used to promote critical thinking shows students report higher use of critical thinking in courses in which 1) discussion was used more frequently and consistently, 2) discussion was a significant element of the course grade (at least 10%), 3) a separate forum was available for socializing, 4) critical thinking was explicitly encouraged, 5) students were given explicit directions for how to participate, 5) instructors posted approximately every 2-10 student postings and purposefully, and 6) instructor comments were neutral regarding ideas, but asked questions and encouraged further thought and discussion.

The best teachers create a natural critical learning environment by 1) posing intriguing problems or questions, 2) helping students recognize the significance of the problem, 3) asking students to answer the question or solve the problem using higher-order thinking, 4) helping students answer the question or solve the problem, and 5) encouraging students to ask the next question and continue inquiring. 6

Retrieved from: In a meta-analysis of studies comparing classroom and online instruction, online instruction was slightly more effective than classroom, and hybrid even more so. This effect was strongest when online conditions supported expanded time on task and opportunities for collaboration. Meyer, K. A. (2003).

Journal of Asynchronous Learning Networks, 7(3), The bulk of postings in threaded discussions fall into the exploration phase, but integration and resolution also occur. Students cite increased time on task and 8
