Analysis of a Global Online Debate and the Development of an Interaction Analysis Model for Examining Social Construction of Knowledge in Computer Conferencing.

This study attempts to find appropriate interaction analysis/content analysis techniques that assist in examining the negotiation of meaning and co-construction of knowledge in collaborative learning environments facilitated by computer conferencing. The authors review strengths and shortcomings of existing interaction analysis techniques and propose a new model based on grounded theory building for analyzing the quality of CMC interactions and learning experiences. This new Interaction Analysis Model for Examining Social Construction of Knowledge in Computer Conferencing was developed after proposing a new definition of “interaction” for the CMC context and after analyzing interactions that occurred in a Global Online Debate. The application of the new model for analysis of collaborative construction of knowledge in the online debate and in a subsequent computer conference are discussed and future research suggested.

Social Presence as a Predictor of Satisfaction within a Computer-mediated Conferencing Environment

Abstract Based on the GlobalEd inter‐university computer conference, this study examined how effective “social presence” is as a predictor of overall learner satisfaction in a text‐based medium. The stepwise regression analysis converged on a three‐predictor model revealing that social presence (the degree to which a person is perceived as “real” in mediated communication), student perception of having equal opportunity to participate, and technical skills accounted for about 68% of the explained variance. Social presence alone contributed about 60% of this variance, suggesting that it may be a very strong predictor of satisfaction. Reliability data on the social presence scale is provided. The results also indicated that participants who felt a higher sense of social presence enhanced their socio‐emotional experience by using emoticons to express missing nonverbal cues in written form. These findings have implications for designing academic computer conferences where equal attention must be paid to desig...

Developing, Testing and Refining of a Model to Understand the Relationship between Peer Interaction and Learning Outcomes in Computer-Mediated Conferencing

Our pervasive adoption of CMC in higher education has far outpaced our understanding of the nature of CMC and, accordingly, how this medium should best be used to promote higher‐order learning (Garrison, Anderson, & Archer, American Journal of Distance Education, 15(1), 7–23, 2001). Therefore, this study examined the relationship between peer interaction and learning outcomes by creating and testing through structural equation modeling a model of five variables—learner characteristics measured by self‐construal, perceived teaching style, task design, course requirements, and prior CMC experience—that influence self‐reported peer interaction and self‐reported learning outcomes. The results showed that perceived teaching style had a small direct effect (0.23) and prior CMC experience had a moderate direct effect (0.31) on self‐reported peer interaction; self‐reported peer interaction had a strong direct effect (0.66) on self‐reported learning outcomes.

A Cross-Cultural Study of Group Process and Development in Online Conferences.

Employing survey and focus group data, this study examined if there are differences in perception of online group process and development between participants in Mexico and the United States of America (USA). Survey data indicated significant differences in perception for the Norming and Performing stages of group development. The groups also differed in their perception of collectivism, low power distance, femininity, and high context communication. Country differences rather than age and gender differences, accounted for the differences observed. Focus group participants identified several factors that influence online group process and development: (1) language; (2) power distance; (3) gender differences; (4) collectivist vs. individualist tendencies; (5) conflict; (6) social presence; (7) time frame; and (8) technical skills.

Symptoms and coping in Sri Lanka 20–21 months after the 2004 tsunami

BACKGROUND The estimated prevalence of clinically significant psychiatric and somatic symptoms in adults >1 year after the 2004 Asian tsunami is unknown. AIMS To estimate the prevalence of psychiatric and somatic symptoms and impairment in Sri Lanka 20-21 months after the 2004 Asian tsunami, and to assess coping strategies used by tsunami-affected individuals that contribute to post-tsunami adjustment. METHOD Homes from one severely affected area were randomly selected, and adult respondents were sampled utilising a modified Kish method. Instruments were administered in Sinhala to assess exposure, post-traumatic stress disorder (PTSD), depression, anxiety, somatic distress and impairment. Demographic variables and culturally-relevant coping activities were assessed. RESULTS The prevalence of clinically significant PTSD, depression and anxiety was 21%, 16% and 30% respectively. Respondents reported a mean of eight persistent and bothersome somatic complaints, which were associated with psychiatric symptoms and impairment. Thinking that ones life was in danger was the exposure item most strongly associated with symptoms and impairment. The majority of respondents found their own strength, family and friends, a Western-style hospital and their religious practice to be the most helpful coping aids. CONCLUSIONS A large minority of adults in one area of Sri Lanka reported significant psychiatric and somatic symptoms and impairment 20-21 months after the tsunami. Accurate data about risk for and resilience to impairing symptoms >1 year after disasters are necessary in order to develop rational surveillance and interventions.

New Model, New Strategies: Instructional design for building online wisdom communities

We discuss the development of an instructional design model, WisCom (Wisdom Communities), based on socio‐constructivist and sociocultural learning philosophies and distance education principles for the development of online wisdom communities, and the application and evaluation of the model in an online graduate course in the USA. The WisCom model aims to facilitate transformational learning by fostering the development of a wisdom community, knowledge innovation, and mentoring and learner support in an online learning environment, based on a “Cycle of Inquiry” module design, and a “Spiral of Inquiry” program design. Extending beyond current instructional design practice, WisCom provides both a new model for teaching that builds upon the inherent capacity of networked communication to support the growth and intellectual development of communities of practice, and a new model of learning where learners engage in the process of scholarly inquiry that supports individual and collective learning. Evaluation and research data support the WisCom models ability to design a learning community engaged in the collaborative construction of knowledge.

The Effect of Three Computer Conferencing Designs on Critical Thinking Skills of Nursing Students

A study of university nursing students tested the effect of computer conference designs and advance organizers on critical thinking skills. Critical thinking, although not significantly different between three conference groups, was evident for groups in all three conference designs. Those conferences designed to facilitate critical inquiry showed higher critical thinking means. No significant differences in critical thinking were found between groups receiving advance organizers and those not receiving advance organizers. Critical thinking dispositions and critical thinking skills of conference participants were positively correlated (r = .26, p < .05).

Predictors of learner satisfaction in an academic computer conference

This study tested the Adult Distance Study Through Computer Conferencing (ADSCC) model developed by Eastmond (1994), to determine if learner readiness, online features, and CMC‐related learning approaches are associated with learner satisfaction in an academic computer conference. All three variables were correlated with learner satisfaction and online features emerged as the best predictor of learner satisfaction. Results indicate interrelationships between the three variables. The ADSCC model was a good predictor of learner satisfaction. It provided a useful framework for understanding learner satisfaction by showing how to categorise the different components that influence satisfaction in an academic computer conference.

Predictors of Learner Satisfaction and Transfer of Learning in a Corporate Online Education Program

Abstract This study explores factors that predict learner satisfaction and transfer of learning in an online educational program at a multinational corporation, established to improve organizational learning by providing training in technical skills. A mixed-methods design was used, selecting both quantitative methods (utilizing survey research) and qualitative methods (employing open-ended questionnaire items, face-to-face and phone interviews), gathering the perspective of students, instructors, and instructional designers. The online courses were designed using a problem-centered and case-based approach to learning and utilized technologies including learning management systems such as Blackboard and SharePoint as well as instructional design tools such as Breeze, Captivate, and PowerPoint. Online self-efficacy emerged as the strongest predictor of learner satisfaction; collegial support was the strongest predictor of transfer of learning. Qualitative analysis provided additional insight on these findings and the elements that impacted the operation of an online education program in a corporate setting.

Building an online wisdom community: A transformational design model.

THIS PAPER discusses the development of a new instructional design model based on socioconstructivist learning theories and distance education principles for the design of online wisdom communities and the efficacy of the model drawing on evaluation results from its implementation in Fall 2002. The model, Final Outcome Centered Around Learner (FOCAL), aims to facilitate transformational learning by fostering three dimensions: the development of a Wisdom Community, Knowledge Innovation, Mentoring and Learner Support, in an online learning environment. The theoretical framework for the FOCAL model is grounded in socioconstructivist learning theories that focus on the link between cognitive and social processes in understanding learning.
