Fótons como mediadores em processos eletrodinâmicos: Uma proposta de ensino

Abstract

Modern and Contemporary Physics plays a relevant role in the scientific knowledge and technological production of today's society. Students of the various levels of schooling deal with a universe in which science and technology have become almost fundamental elements in today's life. This finding points to the need to study this knowledge in Basic Education and generates the following indignation: Would the insertion of Modern Physics in Physics classes in High School would lead the students to establish any relation with the knowledge of Classical Physics? From this questioning, it is believed that contents of Modern and Contemporary Physics can be inserted in connection with Classical Physics. It is adopted that the results of this action, could contribute to facilitate the students' understanding in the study of this new knowledge. Faced with this, it is proposed with this research, the use of photon through the Photoelectric Effect, as mediator of processes in Electrodynamics in the teaching of Electricity contents in High School. The proposal involves the following actions: (i) Experimental and / or observational activities that may facilitate the student's understanding of this knowledge using the LPS (Didactic Sequence) as a pedagogical tool; (ii) Application of these concepts in the production of projects involving the phenomenon of the Photoelectric Effect, seeking a connection between theory and practice, seeking to encourage students to produce simple objects / apparatuses in function of the acquisition of this knowledge. This research constitutes a proposal that seeks to facilitate the flexibility of pre-established program contents for High School, which are always worked in a sequence also pre-established. And therefore, in this perspective, insert a content of Modern Physics in connection with Classical Physics and challenge the physics teacher to incorporate other contents of Modern Physics into Basic Education.
