Efeitos de atividades investigativas, sobre os métodos de preparo da bebida do café, na aprendizagem significativa do conceito de extração

Abstract

The present research, of a descriptive-exploratory nature, aims to evaluate the influence of Investigative Activities on the ability to relate chemical concepts, in specific educational contexts, by chemistry graduates participating in the Pedagogical Residency project - Chemistry subproject, at the Federal University of Alfenas (Minas Gerais). We identified, through sessions, studies and interviews, the students' previous knowledge about Ai, as well as the process of tasting the coffee drink. After collecting students' previous conceptions, we planned intervention activities to overcome these students' motor difficulties. We base this work, as well as the analysis of information in budgets on the Theory of Meaningful Learning proposed by David Ausubel. We present the contributions of the use of Investigative Activities for the elaboration and conceptual re-elaboration and for the initial formation of the students, through the analysis and interpretation of the answers of the students in the teachings, studies and interviews, carried out by the researcher. The results indicate that the use of these activities contributed to a significant learning of the concept of inheritance. In addition, the participation of students in AIs contributed to initial teacher training, in the sense of thinking about the use of such activities as a didactic strategy.
