Abstract [en]

In this experiment we explore the effects of using a graphical and textual database for sharing information within a team that are to control a dynamic system. The task involves fighting a simulated fire. Four people are to cooperate in a layered organisation, with one layer being the operative and the second layer the supervisory. The operative layer involves two fire chiefswho are commanding two fire units each. The supervisory unit consists of two persons that are to co-ordinate the fire chiefs. The supervisory unit receives all information from the fire chiefs but has to construct an overall picture, a so-called situation awareness, of the development of the whole area. The supervisory unit constructs this situation awareness which is meant to be supported by the graphical and textual databases respectively. We hypothesised that the graphical condition would be more successful than the textual database in registering the current situation, since the graphical database allows direct mapping. On the other hand, we hypothesised that the textual condition might be better in supporting the future planning and prediction of system dynamics. We analyse 18 quartets, 72 subjects by both performance measures and a questionnaire. There were no significant performance differences between conditions, but there is a major learning effect, especially for the textual condition. In accordance with our hypothesis we found that participants in the graphical condition did better mapping the map with the "real" world, at least in the first session. More successful groups worked more ahead of the fire than did less successful groups. From the questionnaire it seems that the subjects learn more about co-ordination and trusting their fellow team members than about the internal dynamics of the simulated fire. In fact, the teams learn things about system dynamics that are wrong. We therefore suggest that team SA might be more of a co-ordination problem than a problem of acquiring knowledge about system dynamics.

Abstract [en]

In team collaboration training, especially when the training is distributed on the net, it exists a problem of identifying the students' collaboration and work processes. An important design task when developing distributed interactive simulation systems for team training is therefore to define a proper monitoring functionality that will help training managers to evaluate the training. Thus a goal of a computer-based monitoring system is to give training managers help in understanding and assessing the performance of the trainees.

This thesis deals with the design and implementation of monitoring strategies for distributed collaboration training. The aim has been to explore different automatic monitoring strategies, and how they can help a training manger in their task of understanding the students' collaboration during a training session.

To explore possible monitoring strategies, a distributed, net-based micro-world simulation and training system, C3Fire, has been developed and three series of experiments has been performed. C3Fire provides a Command, Control and Communication training environment that can be used for team collaboration training of emergency management tasks. The training domain, which is forest fire fighting, acts as a micro-world, which creates a good dynamic environment for the trainees.

In the three performed studies a total of 192 persons have participated as students. A 132 of these were computer-literate undergraduate students and 60 professional military officers. In these studies four monitoring goals have been explored: the effectiveness of the teams, the information distribution in the organisation, the students situation awareness, and the students work and collaboration methods.
