Experimental activities of demonstration for the education of the alternated

Abstract

A set of experimental activities demonstration was developed to be presented in classroom to evaluate the possibility of teaching the alternated chain in the Physics High School Curriculum on introductory level. The choice of the proposal activities was guided by a previous conception sounding out on alternated chain that Physics High School students have, while the strategy for this presentation in classroom followed instructions of Vygotsky s Social Interaction Theory. At the end, we evaluate the results of the experimental activities demonstration comparing them with the initial data sounding out. The analysis of the questionnaries answers showed us that a great deal of students acquired knowledge on nature of the electrical alternated chain.
