The authors have been developing an education system that supports university-level group exercises related to the design and implementation of information systems. The system is composed of three sub-systems: group organization, electronic textbook creation and software development process support. These are flexibly integrated via databases. The authors applied this system to an actual class at their university, and evaluated the system based on quantitative data from exercise outputs and student questionnaires. The questionnaire results indicated that the system was especially effective for document creation and for monitoring progress among group members. Groups that used the system created more documents than those that did not. Personal progress reports were the most frequently created documents.
