The experience accumulated in the Electronic Engineering Department of the Technological Educational Institution (TEI) of Athens indicates that laboratory instruction although is planned to complement theoretical instruction, with practical applications, in practice it doesn’t seem to respond successfully to its specifications and meet the existing needs. This aspect has been proved by a thorough study related to the evaluation of the students’ performance. A packet of measures are suggested for the development of a new spirit in laboratory instruction including a curriculum reform to ensure that students have opportunities to develop the knowledge, skills, and attitudes to conceive and design complex systems and products.
