An intervention in the teaching of electricity and domagnetism using the photoelectric effect

Resumen

This work consists of a proposal to insert a content of Modern Physics, the photoelectric effect, in a didactic sequence on electricity and magnetism, discussing that it is possible to work concepts that, normally, are approached in an isolated way, within a "box" of Modern Physics, along with the contents of the so-called Classical Physics. For the elaboration of this proposal it was necessary to analyze how it would be possible to correlate the study of the photoelectric effect, through an experimentally demonstrated application, with topics of the contents of Electricity and Magnetism. After this initial study, it was understood that the phenomenon, along with the suggested application could be addressed within the topics of electrification processes, electrical circuits and magnetic field. It was then possible to produce a didactic unit with the sequence of classes and a methodological proposal for the application with the aid of a simulator available on the internet and a demonstration experiment on the application of the photoelectric effect in automated lighting systems. Respecting the sequence of presentation of the topics, usually arranged in textbooks, it was possible to realize that the proposal is feasible and has the potential to facilitate the understanding of the contents related to the theme, since it provides learning through an application of Physics in everyday life.
