TEACHING WAVES AND ELECTROMAGNETISM USING AN AM/FM RADIO ASSEMBLY

Radio AM/FM. Waves. Electromagnetism.

As science evolves, the teaching-learning process, mainly in physics, challenges the teacher to develop strategies with non-traditional methodologies that facilitate the understanding of the contents by the students. So in this work, an educational product was developed - a handout containing an experimental script that aims to improve and encourage learning about waves and electromagnetism. The implementation of the product was carried out through experimental classes, the students were able to relate previous knowledge with new concepts, interacting with each other, mediated by the teacher, during the assembly of a portable pocket AM/FM mini radio kit and in the installation of a galena radio. The application was divided into five stages and had the participation of a group of third year students from the State Elementary and hight School Carlos Drummond de Andrade, in Cacoal city, RO. The comparison between the results of questionnaire 1 – assessment of prior knowledge about waves and electromagnetism and the results of questionnaire 2 – assessment of learning about waves and electromagnetism after application of the product, showed a positive performance in understanding the contents covered. Finally, the results of the opinion questionnaire - evaluation of the research project in the students' perception confirmed the good acceptance of the methodology adopted and that the use of experimental practices is effective for a more meaningful learning in Physics.
