Uma abordagem experimental para o ensino de dualidade onda-partícula no ensino médio

Abstract

This work develops a proposal for introducing modern physics in high school, based on an experimental sequence and discussion of its results. The objective is that, based on the analysis of experiments that study light’s nature and classroom debates led by the teacher, the students can identify a discrepancy between the classical physics theory they have studied so far and the results obtained experimentally. The teacher then continues to guide the class towards understanding the need for a new physics concept, the wave-particle duality. The didactic sequence is developed with the objective of being accessible to the various Brazilian educational contexts. Therefore, it is phenomenological, without depending on mathematization or previous theories of high difficulty. It also requires low-cost and easily accessible materials to carry out its experiments.
