Cooperative creation of concept keyboards in distributed learning environments

In this paper we introduce CoBo, a collaborative system supporting cryptographic protocol learning, which offers an interface for the cooperative creation of concept keyboards. Concept keyboards are input interfaces created by the user during runtime with the goal of meeting the user´s need for interaction. Experiments with an early version of CoBo have shown that, although students recognize the power of collaborative learning, they found a collaborative simulation of cryptographic algorithms should be associated with an additional step in the learning process: the collaborative design of the concept keyboards that will be used to perform the collaborative simulation of cryptographic protocols.
