Traditional distinctions between work/play and classroom/gamespace create barriers to computer games’ integration into academic settings and the writing classroom in particular. For a writing class, the work/play distinction often relegates games to an object of analysis in which students critique the games but have little invested in the gameplay itself. After examining briefly how historical changes in education created these distinctions, we offer an alternative position that places play and gamespace within the realm of the classroom. In so doing, we open up a gap for computer game theory to inform the pedagogy that can be practiced in a writing classroom. We show one such example of game theory informing writing pedagogy—the theory of emergent gaming. We then offer an example of an enacted emergent pedagogy in which students play the massively multiplayer online role-playing game World of Warcraft throughout the term, composing self-determined, rhetorically focused writing projects informed by play and written for other game players. 相似文献

The information accessible through the Internet is increasing explosively as the Web is getting more and more widespread.
In this situation, the Web is indispensable information resource for both of information gathering and information searching.
Though traditional information retrieval techniques have been applied to information gathering and searching in the Web, they
are insufficient for this new form of information source. Fortunately some Al techniques can be straightforwardly applicable
to such tasks in the Web, and many researchers are trying this approach. In this paper, we attempt to describe the current
state of information gathering and searching technologies in the Web, and the application of AI techniques in the fields.
Then we point out limitations of these traditional and AI approaches and introduce two aapproaches: navigation planning and
a Mondou search engine for overcoming them. The navigation planning system tries to collect systematic knowledge, rather than
Web pages, which are only pieces of knowledge. The Mondou search engine copes with the problems of the query expansion/modification
based on the techniques of text/web mining and information visualization.

Information retrieval from the World Wide Web through the use of search engines is known to be unable to capture effectively
the information needs of users. The approach taken in this paper is to add intelligence to information retrieval from the
World Wide Web, by the modeling of users to improve the interaction between the user and information retrieval systems. In
other words, to improve the performance of the user in retrieving information from the information source. To effect such
an improvement, it is necessary that any retrieval system should somehow make inferences concerning the information the user
might want. The system then can aid the user, for instance by giving suggestions or by adapting any query based on predictions
furnished by the model. So, by a combination of user modeling and fuzzy logic a prototype system has been developed (the Fuzzy
Modeling Query Assistant (FMQA)) which modifies a user's query based on a fuzzy user model. The FMQA was tested via a user
study which clearly indicated that, for the limited domain chosen, the modified queries are better than those that are left
unmodified.

For educators, the World Wide Web offers a valuable technology for knowledge sharing. It can complement more traditional approaches
to knowledge sharing such as books and lectures. Here, we identify and differentiate three major approaches for Web-based
knowledge sharing: course-centered sites, subject-centered sites, and book-centered sites. A rationale for book-centered sites,
those developed to facilitate students’ and instructors’ efforts in courses that use the book, is advanced. We introduce an
architecture of features that can guide developers of such sites. This is illustrated by a book-centered site implemented
according to the architecture. Several sites for introductory business computing books are compared and contrasted in terms
of the architecture, suggesting ways in which each can be extended.

By transforming the personal computer into a communication appliance, the Internet has initiated the true home computing revolution. As a result, Computer Mediated Communication (CMC) technologies are increasingly used in domestic settings, and are changing the way people keep in touch with their relatives and friends. This article first looks at how CMC tools are currently used in the home, and points at some of their benefits and limitations. Most of these tools supportexplicit interpersonal communication, by providing a new medium for sustaining conversations. The need for tools supportingimplicit interaction between users, in more natural and effottless ways, is then argued for. The idea of affective awareness is introduced as a general sense of being in touch with one's family and friends. Finally, the KAN-G framework, which enables affective awareness through the exchange of digital photographs, is described. Various components, which make the capture, distribution, observation and annotation of snapshots easy and effortless, are discussed. 相似文献

《Ergonomics》2012,55(7):858-868
The beginning of a new century is an appropriate moment to consider the role of ergonomics in relation to the problems facing society. To help solve these serious global problems, ergonomics needs to be open to new disciplines, particularly those in the social sciences. Also, it may be difficult to generalize research on human-centred sociotechnical design without taking into account national characteristics, economics and political constraints. Currently there is more interest than ever in what ergonomics has to offer, but to deliver its promise requires a much broader approach than is usual. By adopting such new approaches one may help solve both the problems of the overdeveloped post-industrial societies and those of the societies of the Third World, where a new approach to work and economics may provide an improved chance for development given the recent changes in global economic policy. 相似文献
