Each category of a tutor’s presence is vital to learning and to the establishment of the learning community; tutors' behavior must be such that they are seen to be “posting regularly, responding in a timely manner and modeling good online communication and interaction” (Palloff & Pratt, 2003, p.118). Without an instructor’s explicit guidance and “teaching presence,” students were found to engage primarily in “serial monologues” (Pawan et al., 2003). Baker (2004) discovered that “instructor immediacy, i.e., teaching presence (Rourke et al., 1999), was a more reliable predictor of effective cognitive learning than whether students felt close to each other. Studies have demonstrated that instructor participation in threaded discussion is critical to the development of social presence (Shea, Li, Swan, & Pickett, 2005; Swan & Shih, 2005) and sometimes not fully appreciated by online faculty (Liu, Bonk, Magjuka, Lee, & Su, 2005). Shea, Li, and Pickett (2006) proposed that teaching presence – viewed as the core role of the online instructor – is a promising mechanism for developing learning community in online environments.
Kristen Della on 30 May 11Immediate Feedback and Opportunity to Revise Answers to Open-Ended Questions. Two experiments examine the psychometric effects of providing immediate feedback on the correctness of answers to open-ended questions, and allowing participants to revise their answers following feedback. Participants answering verbal and math questions are able to correct many of their initial incorrect answers, resulting in higher revised scores. In addition, the reliability of these scores is significantly higher than the reliability of scores based on no feedback. Finally, anxiety is significantly lower following a test section with feedback and revision.
