Using Breakout Rooms in Synchronous Online Tutorials

Student perceptions of participation opportunities in online synchronous tutorials

From a sociocultural constructivist perspective of learning, dialogic interactions between students and tutors support meaning negotiation that leads to knowledge construction. In online educational contexts, interaction between learning parties is largely facilitated by CMC technologies. Most research has focused on asynchronous CMC modes which are held to offer learners an ever-present window...

Online State Space Model Parameter Estimation in Synchronous Machines

The purpose of this paper is to present a new approach based on the Least Squares Error method for estimating the unknown parameters of the nonlinear 3rd order synchronous generator model. The proposed method uses the mathematical relationships between the machine parameters and on-line input/output measurements to estimate the parameters of the nonlinear state space model. The field voltage is...

Online infidelity in Internet chat rooms: an ethnographic exploration

Internet chat rooms have introduced unprecedented dynamics into marital relationships: never in history has it been so easy to enjoy both the stability of marriage and the thrills of the dating scene at the same time. This study examined the phenomenon of online infidelity in chat rooms, a process whereby individuals involved in a long-term committed relationship seek computer synchronous, inte...

Characterising the Quality of Online Task-Based Application Tutorials

End-user authored tutorials are increasingly becoming the norm for assisting users with learning software applications, but little is known about the quality of these tutorials. Using metrics derived from previous work, I characterize the quality of textand image-based Photoshop tutorials available to users online. I compare these tutorials across four sources representing tutorials that are, i...
