No. of bitstreams: 1 DISSERTA??O VERS?O HOMOLOGA??O.pdf: 14613657 bytes, checksum: 59d9f7fcb7ea6c750847d834c7dd1631 (MD5) Previous issue date: 2015-12-04 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / This work had as it main goal the development of an educational product (Didactic Sequence) which is capable of enabling a meaningful learning of Modern and Contemporary Physics concepts from the X Radiation production and Emission Theory During High School years. The current work discussed the influence of the use of a didactic sequence, made upon the M?heut model and based on the Ausubel meaningful learning theory, in the insertion of Modern and Contemporary Physics in High School, through the use of the X radiation production and emission theory as the main theme. A quantitative analysis was performed by using the Pearson's Chi-squared test to verify the likely association between the didactic sequence use and the students' educational achievement from questionnaires elaborated according to the revised Bloom taxonomy.A conceptual maps analysis was performed based on the progressive differentiation and the integrating reconciliation of concepts to verify the occurrence of a meaningful learning by the students related to the X radiation theory conceptions. The quantitative analysis outputs demonstrated a statistically significant association between the experimental classroom students' performance and the use of the educational product (Didactic Sequence), whilst the conceptual maps analysis indicated the occurrence of a meaningful learning based on the progressive differentiation and the integrating reconciliation of concepts, which validates such educational strategy developed for the teaching of Modern and Contemporary Physics during High School Years. / Este trabalho teve como objetivo central desenvolver um produto educacional (Sequ?ncia Did?tica) que possa potencializar a aprendizagem significativa de conceitos da F?sica Moderna e Contempor?nea, a partir do estudo da Teoria de Produ??o e Emiss?o de Radia??o X, no n?vel m?dio de ensino. O presente estudo discutiu a influ?ncia da aplica??o de uma sequ?ncia did?tica, constru?da com base no modelo de M?heut e fundamentada na Teoria da Aprendizagem Significativa de Ausubel, na inser??o da F?sica Moderna e Contempor?nea no n?vel m?dio, utilizando a Teoria de Produ??o e Emiss?o de Radia??o X como tema principal. Foi realizada uma an?lise quantitativa, usando o teste qui-quadrado de Pearson, para verificar a poss?vel associa??o entre a aplica??o da sequ?ncia did?tica e o rendimento dos estudantes, a partir de question?rios elaborados de acordo com a Taxonomia de Bloom revisada. Foi realizada uma an?lise de mapas conceituais com base na percep??o da diferencia??o progressiva e da reconcilia??o integradora de conceitos, para verificar a ocorr?ncia da aprendizagem significativa dos estudantes acerca dos conceitos da Teoria da Radia??o X. Os resultados da an?lise quantitativa mostraram a exist?ncia de uma associa??o estatisticamente significante entre o rendimento dos estudantes da turma experimental e a aplica??o do produto educacional (Sequ?ncia Did?tica), enquanto que a an?lise dos mapas conceituais indicou a ocorr?ncia de aprendizagem significativa, com base na diferencia??o progressiva e reconcilia??o integradora de conceitos, o que valida a estrat?gia de ensino desenvolvida para o ensino de conceitos de F?sica Moderna o Contempor?nea no Ensino M?dio.
