4 Two or more peers working together on a problem from networked machines where peers take turns carrying out the next action. Communication windows are available so that students can send advice, suggest alternative actions, comment on their partner's actions, etc. Peers could work in reciprocal teaching mode or competitive fashion. On the other hand, one peer could act as a coach while the other would attempt to solve the problem. 5 Two or more peers working together with at least one of the peers being simulated by the system.
Peers can take turns carrying out actions with a simulated peer.
The simulated peer can carry out actions automatically or on demand. Simulated peers can be selected from a library of student models. VanLehn et al. Collaborative learning research has not identified formalisms prescribed for an ideal collaborating environment design for peers. It is left as a subjective assessment and prescription depending on the application, peers, and collaborative environment.
