Abstract

This work identifies significant aspects of the application of chemistry teaching proposal which involves research students about the popular knowledge of the preparation of bread and wine. Through the study of fermentation processes, we sought to contribute to appropriation of chemical language. Implementation of the proposal was held with a group of 3rd year of high school a school of state schools, the State Preparatory High School Our Lady of Patronage, located in Dom Pedrito, in the state of Rio Grande do Sul. The data from this study were collected through questionnaires, textual productions, exercises, reporting and notes taken by the researcher during interventions, and analyzed using an approximation of Textual Analysis Discourse. The proposal backed the role of the students who remained motivated from the start of the work, and particularly during the experimental activities. Among the survey results, we highlight the context of chemical classes, which contributed as a different tool for understanding everyday and especially the relationship between popular knowledge and educational content, as well as the active participation of students, contributing to improving the teaching and learning process.
