    This study aims to theoretically explore whether Massively Multiplayer Online Game (MMOG) is an effective collaborative learning environment, empirically examine the occurrence of knowledge creation in MMOG game-play, and conceptually advocate the research potential of MMOG game-based collaborative learning. Although a growing number of researchers have started to use MMOG as a new generation of educational platform, the study of the theoretical justification for the occurrence of collaborative learning behavior in MMOG are still under-researched. To bridge this gap, this study integrates MMOG and technology-based collaborative learning streams of research to theoretically explore whether MMOG is an effective learning platform based on Alavi’s three attributes of effective technology-mediated collaborative learning environment. In order to examine the occurrence of knowledge creation in the MMOG game-based collaborative learning, we propose definitions of explicit and tacit knowledge in MMOG. Then we conduct an exploratory study using a semi-structural interview approach to collect qualitative data, in order to support our stipulation of the occurrence of four modes of knowledge conversion in MMOG game-play based on the Nonaka’s dynamic theory of organization creation. According to our research findings, this paper advocates research potential of MMOG game-based collaborative learning in future research

    Massively Multiplayer Online Game (MMOG) is a unique categorization of electronic game which allows thousands of players to play simultaneously through the Internet in the same virtual environment. A number of researchers have started to introduce the use of MMOG as a new generation of educational platform, allowing players to interact and to learn together through collaborative game-play. However, the answers for the occurrence of collaborative learning behaviour and the motivational drivers for learning collaboratively in a MMOG are still underresearched. Motivated by such concerns, this study tests a theoretical model to explain individual’s intention to learn by peer motivations. The model employs motivational theories to propose two external motivational factors, namely peer intrinsic motivation and peer extrinsic motivation, and investigates effects of the two new constructs on MMOG players’ intention to learn individually and intention to learn collaboratively by building on the cognitive learning theory. Based on a study with 94 valid current MMOG player responses, PLS analysis shows that peer intrinsic motivation to play has a significant positive influence on the intention to learn collaboratively, while peer extrinsic motivation to play has a significant positive influence on the intention to learn individually. The results of our findings indicate potential implications to researchers, educators and game developers

    Poster Session: P-69Transition metal complexes have been widely used as light-emitting and photon-absorbing materials in optoelectronic devices with diverse applications. While these complexes have been intensively studied in the field of organic light-emitting devices (OLEDs) due to their inherently high phosphorescence quantum yields …postprin

    The Role of Dairy Products and Milk in Adolescent Obesity: Evidence from Hong Kong's "Children of 1997" Birth Cohort

    Background: Observational studies, mainly from Western populations, suggest dairy consumption is inversely associated with adiposity. However, in these populations the intake range is limited and both diet and obesity may share social patterning. Evidence from non-Western developed settings with different social patterning, is valuable in distinguishing whether observed associations are biologically mediated or socially confounded. Objective: To examine the associations of milk or other dairy product consumption with adolescent obesity. Methods: We used multivariable linear regression models to examine the associations of milk or other dairy product consumption, obtained from a food frequency questionnaire, at 11 years with body mass index (BMI) z-scores at 13 years and waist hip ratio (WHR) at 11 years, in 5,968 adolescents from a Chinese birth cohort, comprising 88% of births in April and May 1997. We used multiple imputation for missing exposures and confounders. Results: Only 65.7% regularly consumed milk and 72.4% other dairy products. Milk and other dairy product consumption was positively associated with socio-economic position but not with BMI z-score or WHR, with or without adjustment for sex, mother's birthplace, parental education, physical activity and other food consumption. Conclusions: The lack of association of milk and other dairy product consumption with adiposity in a non-Western setting was not consistent with the majority of evidence from Western settings. Observed anti-obesigenic effects in Western settings may be due to socially patterned confounding. © 2012 Lin et al.published_or_final_versio
