10 11 Abstract Collaborative learners are often meant to be guided by collaboration scripts to 12 identify, discuss, and resolve differences of opinion and knowledge. How learners engage in 13 and resolve conflict, however, may be highly dependent on learners’ cultural background. In 14 this article, we examine the extent to which a peer-critique collaboration script induces socio15 cognitive c...

This paper examines the facilitator, group member, and system roles as a complete socio-technical system. Each of these three components of the sociotechnical system is discussed in terms of the roles that they play within the context of the group meeting. This research draws from previous work on "group roles" to define how these "roles" interact to accomplish effective group per formance. The...

This paper considers the effects of a two-period interaction on the decision of a principal to delegate authority to a potentially biased but better informed agent. Compared to the (repeated) one-period case, the agent’s first period actions may also signal his type which in turn impacts wages in Period 2. As a result, biased agents have an incentive not to follow their own preferences in Perio...

Industry reports continue to highlight the importance and growth of e-learning. However, researcher, trainers and trainees all agree that elearning is different in terms of the level of personalization and anxiety that it brings, and its impact on outcomes. This paper presents a research model to reframe the dominant theory in technology training, i.e. Socio-Cognitive theory and its impact on l...

This paper presents empirical evidence concerning the application of digital video technologies for creating design-based learning environments for middle school students. In three studies we show how the affordances and constraints of digital video technology can support for students their (a) cognitive (b) action related and (c) socio-cognitive learning processes in the domain of history. We ...
