This paper deals with a design of a CSCL (computer supported collaborative learning) referred to as "ProjectBoard", which displays an awareness of task status and division of labor in project-based learning (PBL). According to the situated learning theory, learners learn not only the cultural practice but also the "legitimate learning strategy" which refers(More)
In this paper, we describe an aspect of collaboration—emergent division of labor—wherein people interactively and contingently organize, maintain, and reorganize the division of labor. The emergent division of labor involves the following characteristics: (1) Emergence of division of labor, (2) Maintenance of division of labor, and (3) Reorganization of(More)

Antigenic variation of pseudorabies virus glycoprotein g II was demonstrated in field isolates by neutralizing monoclonal antibodies. Mutants capable of avoiding neutralization by the monoclonal antibodies specific for glycoproteins g II and g III could be obtained from the parent virus by mutagenesis.
In this paper we propose new quantitative metrics that express the characteristics of current general practices in slide-based presentation methodology. The proposed metrics are numerical expressions of: 'To what extent are the materials being presented in the prepared order?' and 'What is the degree of separation between the displays of the presenter and(More)
The authors developed reading support software " eJournalPlus " designed to assist learners in not only reading texts but also constructing their own opinions from it. Since it is difficult for learners to reach a sufficient level of critical reading skills through reading only by themselves, a collaborative learning function was added to allow learners to(More)
