The feasibility of using a computer-based networked collaborative concept mapping system to measure teamwork skills was studied. A concept map is a node-link-node representation of content, where the nodes represent concepts and links represent relationships between connected concepts. Teamwork processes were examined for a group concept mapping activity using networked computers and HyperCard software developed for the study. Two pilot studies investigated the feasibility of the approach, and one of these is reported in this study. Thirty 9th graders worked together in the first pilot study to create collaborate maps on the computer systems. Results of this study and a second confirmatory study resulted in development of a study with 23 groups of 3 students each from middle schools and high schools. Usable data were recorded for 15 groups (45 participants). Results suggest that the real-time measurement of teamwork skills is feasible and that students using the networked computers were able to create a concept map jointly. The number of concepts used by groups ranged from 7 to 18, and the number of links ranged from 8 to 26. It is suggested, however, that the task involved may be more like a small group task than a "team" task if the purpose of a team is defined as performing a task an individual cannot perform alone. The developed software architecture has been designed to be domain independent and should be useful in other computer-based team environments. (Contains 1 figure, 8 tables, and 20 references.) (SLD)
