OCOWS (Online Cooperative Working System) is an on-line didactical software applying the Problem-based Learning (PBL) approach, well known in the educational community. Its essential feature is the incorporation into its unique user interfaces the three working areas:
The teaching strategy applied with this software is the enforcement for participation of the students in the learning process. Moreover, it is convenient and comfortable to use this software in asynchronous mode for homework within one or two weeks. By applying the PBL approach, the teachers don’t have to restructure the whole course's content into "problems" as complained by many of them. What they will need to do is simply select a homework with a reasonable size, then break it down to smaller units, each of which corresponds to an individual work within one or two weeks, or more in the case of a project. PBL is a student-centered learning approach. By using OCOWS, one can carry out the student's cooperation (each of them is responsible of a topic) as well as their collaboration (by sending comment messages to each other) in order to resolve the given problem. The teacher's role is also enhanced by their interventions at any time, if necessary.
