On the other hand it should be observed that the lack of floor control did not seem to create any confusion or conflicts to the corresponding pairs of group B. Real-time collaborative modelling over low-bandwidth networks. However when a user selects an object in order to perform an operation, this is locked temporarily until the operation is terminated by this user.

The solutions produced by the group of students who had to use explicit floor control were of similar quality to the reference group who did not use such a mechanism. If you think you should have access to this title, please contact your librarian.

Extract of a history logfile from collaborative modelling from Fidas et al. Design of the shared drawing board The main activity space of the MS modelling environment needs to be shared by multiple actors, permitting collaborative modelling activities of learning actors at a distance.

Modelling Space and Time: The Event History Approach

Skip to search form Skip to main content. Modellingzpace promotes an exploratory modelling learning approach. This decision to disentangle, the logfiles from the heavy structures associated with multimedia entities is made in order to keep the history logfiles small in size and facilitate their easy exchange and storing.

The main decisions concerning mmodellingspace architecture are related to the development of the synchronous and asynchronous collaboration functionality, as well as the integration of supervision tools in the architecture. However all additional operations outside this shared workspace, should be performed independently by partners involved, a model level coupling approach according to Suthers Thirty-two 32 students participated in the experiment in the frame of a scheduled lab session.

Components of ModellingSpace architecture The ModellingSpace MS software is a client-server distributed application, which comprises a suite of interconnected tools to support collaborative modelling activities.

The open character of MS means that students have access to an open set of primitive entities that can be used for building these models. Evaluating system-based strategies for managing conflict in collaborative concept mapping C. Experiments with this floor control mechanism, see also Fidas modelljngspace al. This is done transparently from the user, so no explicit floor control mechanism is imposed, like in the previous case and activity in the shared activity space is more fluent.

As described in Avouris et al.

You're using an out-of-date version of Internet Explorer. This environment has been designed and built, based on experience with existing previous tools, like ModelsCreator 2. The activity can be reproduced using the playback tool. This mechanism is supported by key request, key accept, key reject functions. Search my Subject Specializations: This decision is necessary in order to avoid users concurrently interacting with the same object, canceling each-others actions, like modifying the text of a concept or the value of variable.

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 main functionality of the Supervision tool is the presentation and processing of logfiles which have been produced during MS activities.

The location of the partners was such within the class that they could interact exclusively through the provided tools. The architecture and evaluation of modellinbspace collaborative learning environment.

Group B was more active than A, while interaction was more symmetrical among partners in the explicit floor control group A. Architectures for computer supported collaborative learning Daniel Modellingsppace.
