The Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, is deploying a flexible learning scheme for selected pilot courses in engineering education. In such a scheme, traditional lectures and written exercises are combined with additional Web-based learning resources. The main objective of this initiative is to sustain the evolution from traditional teaching to active learning and to better integrate the increasing number of educational resources available online. In engineering education, a key activity to sustain the learning process is hands-on experimentation carried out using either simulation tools or real equipment. This paper describes how a collaborative Web-based experimentation environment has been introduced at the EPFL for providing more flexibility to students performing laboratory experiments in automatic control, biomechanics, and fluid mechanics. It particularly describes the eJournal, a Web service integrated in the proposed learning environment that enables the collection and sharing of preparatory notes and experimental results with both peers and teaching assistants.
