Abstract

This research examined the pedagogical potential of the relationship between theory and practice in Chemistry teaching through laboratory practice in professional education of high school level. It had the following research question: in which way the teaching of Chemistry, combining theories and laboratorial practices, enhance the improvement in the quality of learning? This study hypothesized that this association contributes positively to improve the teaching of Chemistry as well as relativizes the assertion that this discipline is difficult to understand by students. This research was characterized by the use of the deductive and inductive methods, being a field research of bibliographical and descriptive aspects, using the survey technique through questionnaires.
