This study investigates the role of tutors in face-to-face as well as computer-mediated problem-based learning. This study examined whether or not a tutor should use his or her expertise in facilitating small group problem discussion practiced in classroom or in synchronous computer-mediated communication. In one experimental condition, the tutor acted as a moderator providing no information re...

Recent studies in social warmth suggest the essence of physical warmth to the interpersonal interaction and human relationship. Mediated warmth therefore can serve as a computer mediated communication (CMC) when the persons are physically separated. Through this study, a pilot experiment was designed and developed to learn about the possibility of body warmth as an intimate cue when experiencin...

In this paper, we empirically investigate whether people understand irony from computers in order to test the recent argument for an egocentric tendency in irony comprehension. In the experiment, participants took a timed math test comprising 10 questions of 3-digit by 2-digit multiplication. After that, they received a feedback comment on their performance (including potentially ironic sentenc...

In this position paper, I argue, from previous experience working on Computer Mediated Communication and from recent experience studying contexts for computer supported cooperative work such as ambulance control and hospitals, that any use of the Clark Model in design needs to be incorporated within a more general analysis of experiencing relational activity.

Computer-mediated communication (CMC) is a crucial coordination option for knowledge workers who rotate at their discretion across locations and projects. Through field-based research, we find that this discretion may encompass even the act of communication. As incoming information from knowledge worker colleagues overwhelms the recipients, conciseness and brevity communication norms arise to s...

This paper describes the process of developing an interactive mobile system for use in a safety-critical domain. The system was developed to inquire into the extent of which coordination between people carrying out a collaborative work task can be improved by means of computer mediated communication on a mobile device. The application area for the device was controlling and monitoring processes...

The ‘‘Foot-in-the-door’’ is a compliance technique which consists in proposing a little first request to a subject then to submit him/her a second more expensive request. In this way, more compliance to the second request is obtained than in a control situation where this request was not preceding by the first solicitation. Many investigations on this paradigm generally used an interaction in f...

The current study measured the influence of national culture, anonymity levels, and technological support (CMC and non-CMC) upon participation input and participation equality within and between forty-two U.S. and Mexican groups constituting a total of 469 participants. Results indicate that both U.S. and Mexican groups supported by CMC technology (i.e., group support systems) were more product...

A two-part assignment was designed which paired students together using e-mail technology that required them to engage in peer teaching. This allowed us to study computer-mediated communication that was not part of a discussion group or chat room. An analysis of the e-mails revealed that males and females did not differ in frequency, length or use of social incentives. Males sent slightly more ...

ABSTRACT The Mathematical Discussion System (MDS) is a software system for supporting online discourse embedded in the context of an electronic educational text. Our goal was to create a new type of electronic resource that built upon the strengths of resources that are currently available to University students. Users of our system visit a specially formatted web page and are able to use our s...
