The purpose of this study is to investigate the effects of asynchronous computer-mediated versus conventional corrective feedback on learners' writing accuracy. Three groups of learners took part in the study: asynchronous feedback group, conventional feedback group, and a control group. Asynchronous feedback group students received explicit feedback on the targeted structure via e-mail, while...

This paper presents an approach to effectively support cooperative applications using tailored failure suspectors. Using a group communication subsystem, it is shown how failure suspectors can be configured to model the requirements/semantics of cooperative applications thus avoiding ad-hoc system decisions. This approach is highly relevant in the context of large scale distributed systems like...

In this paper we present a specific phonics based approach to supporting early literacy. The application system is cooperative and embedded in a "computer-integrated classroom". It provides an interactive writing environment using a visual palette of letters associated with icons and synthetic speech feedback for the writing results. Ongoing developments enhance the intelligent support modules ...

Cooperative communications, where parallel relays forward information to a destination node, can effectively improve the latency in ad hoc networks. In practice, the performance of data transmission often compromises with the variation of channel coefficient and the mobility of network nodes. The conventional fixed rate cooperative relaying cannot make the outage probability reach zero without ...
