O mundo das partículas: uma unidade de ensino potencialmente significativa para o ensino do modelo padrão da física de partículas elementares no ensino médio

Abstract

This dissertation we present the result of a research whose objective was to investigate possible contributions of a Potentially Significant Teaching Unit for the learning of concepts related to the Standard Model of Elementary Particle Physics. The approach of this Unit was based on David Ausubel's theory of meaningful learning. The Teaching Unit was applied in a high school of the state education network of Mato Grosso do Sul, in three classes of third year, approximately during three weeks. For analysis of significant learning cues, we used as instruments of data collection: questionnaires, timeline and conceptual map. The research used qualitative methodology. For the development, structuring and implementation of the LIFO, various specific steps have been taken, including the creation of Quadricorn History - A Journey to the World of Particles. The validation and diagnosis of what the students assimilated and accommodated in their cognitive structure was made through the evaluation activities developed during the implementation of the LIFO. In the end, most of the students demonstrated satisfaction with the proposal and the analysis of the results showed signs of meaningful learning.
