| Resumo: | We are at all times bombarded by new technologies that allow us many exploits, many of
them unimaginable decades ago. In this scenario, the film industry further enhances the
popular imagination by displaying, for example, hypothetical interactive holograms
through science-fiction films and superheroes. In addition to the cinemas, we can also
mention the holograms in several other scenarios (awards events, marketing and electoral
campaigns, music shows, among others), some of which use devices commonly known
as "holographic" pyramids. These pyramids can provide the clear impression that the
viewer is observing a real and tangible object. However, as discussed in this dissertation,
most of these references to holographic images are mistaken, that is, in addition to not
being holograms in fact, they are just two-dimensional images. This can generate
excellent educational opportunities for the debate on the themes of optical illusions and
holograms, especially when we consider the transition from the naive curiosity of the
individual to an epistemological curiosity. In this way, we developed an educational
product through a didactic sequence for the introduction to the study of optics in
elementary education. We take as a starting point the construction of a quadrangular
"holographic" pyramid and investigate its physical principle of functioning. The didactic
sequence was structured according to the three pedagogical moments (initial
problematization, organization of the knowledge and application of the knowledge)
developed by Demétrios Delizoicov and that have freirian educational bases. Through the
application of the didactic sequence, we show the main results, obstacles, expectations
and generate the final educational product including suggestions of applications in the
other levels of schooling. Among the results achieved, we highlight playful aspects
identified in the "holographic" pyramids that favored the introduction of basic concepts
of optics and mathematics in elementary education, as well as immersion in several
factors of scientific construction, such as the formulation and verification of hypotheses
and the collection and interpretation of data. |
