Dissertação (Mestrado em Ensino de Física em Rede) - Universidade Federal de Goiás, Catalão, 2017.http://repositorio.ufcat.edu.br/tede/handle/tede/7034Modern and Contemporary Physics has aroused enormous interest on young people because it brings topics related to scientific advances. On the other hand, the teaching of Physics in Secondary School is not following these advances in a satisfactory way, this impairs the student education in respect to the scientific literacy and they perception of daily relation with Physics. Therefore it becomes necessary the insertion of topics of Modern and Contemporary Physics (FMC) in high school. There are official documents that guide and regulate the Physics teaching, reinforcing the importance of Modern and Contemporary Physics in classes of High School. Thus, the aim of our work was to teach Modern and Contemporary Physics by using the phenomenon of fluorescence. For that, a didactic sequence, in the form of Potentially Meaningful Teaching Units (PMTU), was developed to work concepts of FMC, as well as the elaboration of a lecture note for the students, with the theoretical support of the subjects treated, and also proposals of experiments involving the phenomenon of fluorescence. In this way, we present a qualitative analysis of the impressions of high school students of a public school about the intervention, using Potentially Meaningful Teaching Units, seeking a meaningful learning in the teaching of Modern and Contemporary Physics. We observed that the students meaningfully learned scientific concepts related to quantization of energy, energy levels, electronic transitions, and many others. They have been able to formulate coherent speeches on the subject. It was possible to perceive the importance of the use of experiments as a didactic approach in secondary education, as well as the need to introduce modern and contemporary physics themes. It was observed the potential of the lecture note and it was concluded that the teaching of FMC contextualized with the daily life of the student combined with the appropriate use of experiments contributes significantly to the student's learning.application/pdfAcesso AbertoFluorescênciaFísica modernaUnidades de ensino potencialmente significativasFluorescenceModern physicsPotentially significant teaching unitsHigh schoolEnsino MédioENSINO-APRENDIZAGEM::METODOS E TECNICAS DE ENSINODissertação
