This study was aimed to compare long-term effects of collaborative and individual task planning on Persian-speaking EFL learners’ writing performance, using Brown and Bailey’s (1985) rating scale. Therefore, a group of 90 upper-intermediate EFL learners in collaborative task planning, individual task planning, and control groups took part in the study. In the experimental groups, the participan...

This work explores a novel approach to the analysis and modelling of computer supported collaborative writing. The aim of this dynamic modelling approach is to capture the structure of user behaviour as they interact with a computer system. Markov chains models are derived from the empirical data on the use of the system. These models are compared so as to highlight how the dynamic structure of...

This paper reviews several user experiences researchers at the University of Arizona have had in building Internet-based tools to support collaborative writing. First, the technological framework for an advanced collaborative writing tool called Collaboratus is presented. Next, we review the tools that make up Collaboratus, and then provide an overview of the various user experiences we have ha...

Increasing complexity in medicine has caused clinical trial experts with disparate backgrounds from multiple organizations to collaborate when developing clinical trial protocols. Although many protocol-authoring tools provide computerbased decision support to assist in protocol writing, few of them provide sufficient collaboration support for a group of protocol writers. The iterative group wr...

In this paper, I review some current technologies and software used in collaborative knowledge building and learning in general and then discuss the interactive system I designed to facilitate collaborative knowledge building and learning in tertiary education. This system is used in conjunction with a wireless intelligent personal electronic response system in the classroom. Contributors and l...
