Roles as a structuring tool in online discussion groups: the differential impact of different roles on social knowledge construction

Impact of Discussion Forums on the Final Scores of Post Graduate Students at Open University Malaysia

At Open University Malaysia (OUM), online discussions serve as a bridge between the face-to-face and virtual lessons. However, for the Master of Instructional Design and Technology (MIDT), the online discussions are the lifeline of students and facilitators as the discussion forum is a place where high level asynchronous communications are triggered. As such it is important to identify such interactions and determine if there is a significant impact on the final grade achieved by students. In this study, an attempt was made to analyse the discussion forum using the Ning social networking site (http://hmid6303.ning.com). A total of 14 students enrolled for the fully online MIDT course offered by OUM. The findings from normality test results (Shapiro-Wilk) indicate that the forum scores were normally distributed (significance value >0.05) and final score shows some deviation from normality (significance value <0.05).

Crowdsourcing Cognitive Presence: A Quantitative Content Analysis of a K12 Educator MOOC Discussion Forum

Massively Open Online Courses (MOOCs) offer participants opportunities to engage with content and discussion forums similar to other online courses. Pedagogical components of MOOCs and the nature of learning are worth of examining due to issues involving scale, interaction and the role of the instructor (Ross, Sinclair, Know, Bayne & McLeod, 2014). The Community of Inquiry (CoI) framework provides a basis for measuring cognitive presence in online discussion forums. As voluntary point of entry to a community of learners, it is important to consider the nature of participant contributions in terms of cognitive presence. This study focused on an educator MOOC because MOOCs have been proposed as an efficient vehicle for providing professional development due to the significant self-identification of participants as educators (Ho et al. 2014). Participant attributes have been categorized, however the discussion forum is difficult to study on a massive scale (Kizilcec, Piech, & Schulz, 2013). Automated measures of cognitive presence may not provide the full view of learning behaviors implicit in messages posted to the forums (Wong, Pursel, Divinsky & Jansen, 2015). To address this gap, the forum messages were hand-coded and analyzed using quantitative content analysis (Neuendorf, 2002). The study found that the measure of exploration increased over the duration of the course. Viewing cognitive presence over time provided a new metaphor for explaining the proportions of cognitive presence in the discussion forum of an educator MOOC. This finding suggests that increased instructor presence during the later stages of the course may increase cognitive presence over time (Akyol & Garrison, 2007; Garrison & Cleveland-Innes, 2005)

Participating in Synchronous Online Education

There is an increasing need for education since the workforce of today is expected to be highly educated and continuously learn. Distance education is a powerful response to meet the growing need for education. Online education, here concisely defined as distance education mediated online, is the most common type of distance education. It mainly relies on asynchronous communication although it is well known that many students regard the lack of synchronous communication as disadvantageous. This thesis aims to achieve a deeper understanding of how, why and when synchronous communication, as a complement to asynchronous communication, affects student participation in online education. In order to study the complex phenomenon of online student participation, various qualitative and quantitative data collection methods for assessing both perceived participation and actual participation were used. The aim was investigated in two offerings of an online undergraduate course and two series of online discussions on master level, and by conducting focus group interviews with experienced practitioners. The findings indicate that synchronous communication has the potential to enhance online student participation. Light was shed on two dimensions of participation, which were labelled personal participation and cognitive participation. The thesis suggests that synchronous communication, as a complement to asynchronous communication, may better support personal participation. This is likely to induce arousal and motivation, and increased convergence on meaning, especially in smaller groups. Synchronous communication seems particularly beneficial for supporting task and social support relations, and to exchange information with a lower degree of complexity. By drawing on the studies of the thesis and previous research, propositions on when to support synchronous communication in online education were suggested
