The mission of the NetPro European project is to develop project-based learning through the Internet. The NetPro project is creating tools and services to facilitate communication and collaboration between distant students, and to manage access and control of project deliverables. NetPro project teams form cross-institutional learning communities. This new learning environment is a distributed system that facilitates sharing and peer reviewing of project deliverables and interaction in special interest group discussions, regardless of how students are organized locally. The outcome of the project also includes practical handbooks for students, tutors, and trainers to support them in making full and effective use of the learning environment. NetPro methodologies and tools are being developed by running pilot projects: the four streams of pilots are briefly described in the paper. A formal evaluation process is an integral part of the project and its preliminary outcomes are discussed. (Author/AEF)
