We lived with the radiation from various sources, both natural and artificial, and
indeed life on Earth exists only because of it being a key aspect of our daily
lives. Although most students have heard about radiation, a significant number
do not know the subject, basic items such as their benefits, and the difference
between ionizing and non-ionizing radiation. The vision of the student is the one
generated by the media, stating that the radiation is harmful. Thus, this study
aims to address the topic in the classroom, through a didactic sequence for
students of vocational education in meaningful learning theory perspective of
David Ausubel, so that takes the student out of the mediatic idea, common
sense, and formulate scientific concepts. The work begins with a brief study of
the meaningful learning and its key employees subsequently approach the
teaching of physics of radiation - ionizing radiation immediately will relate the
physics of radiation with the meaningful learning of Ausubel. Finally we present
the teaching sequence presented to students of the Federal Institute of
Amazonas - IFAM / Manaus Campus Center, and present the results.
