Teaching method
Classes for presentation of the essential concepts with the reflection on the way these concepts were established. Classes for discussion/resolution of problems related to practical situations, orders of magnitude, estimates on the physical quantities concerning the electromagnetism. Laboratory classes to perform some experiments to illustrate essential concepts of electromagnetism. Support to students? individual work so that they can develop a work of information collection, analysis of that information and elaboration of their own notes on the subjects approached in this curricular unit.
