ModellingSpace is a learning environment that allows collaboration of partners, collocated or at a distance in various educational settings. This paper describes the main features of the architecture of the ModellingSpace environment and in particular issues related with coordination and communication during problem solving. The results of an evaluation study of ModellingSpace, which has been recently contacted in order to examine the effect of various levels of locking of objects in the shared activity space are also reported here. Through this study, the effectiveness and the limitations of the proposed architecture are identified and discussed.
