The aim of this study is to examine and describe in what way student teachers use their own and others words meanings content in asynchronous dialogues as a collaborative learning activity in three web-based courses over a period of 60 weeks. The students’ contributions to the course assignments, the group responses and the collaborative discussions were analysed and interpreted based on Bakhti...

For collaboration design we can distinguish between synchronous and asynchronous collaborative working. Both are important and complementary in AEC design. We focus on asynchronous collaborative working. It can be motivated that not separate tools but a complex system of concurrent engineering components linked together by an information logistic system are necessary to cope with the complexity...

We describe a collaborative search system called Results Space to support small groups of users in conducting asynchronous collaborative searches. We discuss the design of the system and present results from a laboratory evaluation. We also describe the development of an asynchronous collaborative task scenario (based on a task from the TREC Robust test collection) designed to elicit naturalist...

This paper discusses how mediation strategies can be used to design a pedagogical agent integrated to a text mining tool to promote collaborative work in academic reading and writing activities. The agent uses the Artificial Intelligence Markup Language (AIML) to communicate with students, while its text mining features enables it to keep track of what is being produced collaboratively. Mediati...

One of the major challenges in asynchronous collaborative environment is to provide a sense of awareness of other users actions. The amount of awareness needed varies due to specific roles users undertake during collaboration. While emphasizing the importance of roles, this paper discussed awareness-role relationship and proposed a role-based approach to specifying the awareness characteristics...

This paper investigates using higher levels of scripted process structure (procedural explicitness) to improve outcomes of distributed, asynchronous collaborative writing (CW) teams that work on the Internet. This paper reports preliminary results of a one-and-a-half month field experiment on asynchronous collaborative writing using 550 participants. It is found that the highest levels of proce...

This paper describes the theoretical foundation, architecture, and implementation of Web-CCAT, a CyberCollaboratory for Asynchronous Teams. Through Web-CCAT students have asynchronous access to software tools such as Group Decision Support System (GDSS); Multi-user, Computer Aided Software Engineering (CASE); and Multi-user Project Management. Because Web-CCAT is a flexible environment, it can ...

1 Current address: Computer Science Department, University of California Berkeley, Berkeley, CA 94720 Abstract Multimedia content is a central component of ondemand training and education delivered over the World Wide Web. Supporting asynchronous collaboration around educational multimedia is a key requirement for making the online educational environment effective. A multimedia annotation syst...

background: cooperative and collaborative learning approach with online programs is useful in response to rising demand for university educational system. this study evaluates the use of internet and computer in collaborative teaching and learning process for post graduate nursing students. method: this is a correlation descriptive study. the population in the study is based on census sampling ...
