A first year student does not usually have much knowledge of what an electronics engineer does, and why such courses like mathematics and physics are studied so much. Specific to electronics is that building even the simplest device requires a relatively great deal of theoretical knowledge. A design-build based CDIO project using many disciplines distinct from one another has therefore been established. Since electronics is developing very fast, lifelong learning skills are important. Also working in groups is essential because problems in electronics are usually complicated and a multidisciplinary and a cooperative learning method like Problem Based Learning is required.
