Sequência didática para o ensino introdutório da física aplicada à radiologia em nível técnico

Abstract

The proposal presented in this research project is directed to the introductory teaching, at a technical level, of the concepts about the production and interactions of X-radiation with matter, phenomena associated with the production of the radiographic image. For this, a didactic sequence was elaborated; a potentially significant teaching unit (UEPS), originally proposed by Moreira (2011), was applied in seven meetings. The UEPS was proposed aiming at meaningful learning, and to reach this objective, the theory of models was used, as proposed by Le Moigne, in 1987. The problem situations were chosen in order to elucidate the forms of production, the parameters of exposure and the phenomena of attenuation of X-Radiation by matter. The proposed activities were collaborative and aimed at the progressive assimilation of these concepts. The product associated with this dissertation consists of four videos, available on the internet, in which interested parties, teachers and (or) students, can have access to the contents and experiments, as proposed in the didactic sequence associated with this dissertation.
