Experimentació amb tecnologia ExAC des d'una orientació de l'ensenyament com a investigació

Abstract

We propose to integrate the performance of quantitative experiments in the physics or chemistry lectures by means of E^xAC (Experimenting with the Aid of a graphics Calculator). This integration reinforces the teaching-learning process and fits perfectly well into the framework of science teaching by guided research. We insist on the convenience of not separating what has traditionally been called «practical work» from the «recitation and problem-solving sessions», i.e., in harmonizing instead of atomizing. This harmoni­zation is favoured if one orients the experiments towards simple designs that allow to concentrate one’s attention in the manipulation of ideas and not in complex set ups. Some specific examples of in-class practice are also given.
