Uma investigação nos periódicos da revista Química nova na escola: a temática “alimentos” em foco

Abstract

In contemporary times, much has been debated about how the relevance of a healthier diet can contribute to good health and quality of life. This topic is inserted in the social sphere and directly linked to the relationship between people, since food and the wellbeing are associated, interfering directly in the body and physical conditions of the society. Chemical knowledge participates in the diffusion between science and technology, thus, by combining a teaching that stimulates the student to think criticallyand to show a position on the discussed issues. It may favor a more motivating learning, thus making the classes more attractive and constructive. By incorporating new approaches, the food context, for example, along with the content of Chemistry, may contribute to the students to get accessto more information on the constitution of the foods and benefits to their health, generating a more critical decision-making in their daily choices. The objective of this study is to investigate the articles published in the Revista Química Nova na Escola, with reference to the theme of food articulated to the teaching of chemistry in the last 20 years. Based on the methodology of Discursive Textual Analysis, a study was carried out to understand how the authors approached the subject of "food" in their chemistry classes. The readings carried out are directed to consider that most of the works apply to the use of methodologies exposed in the contextualized form or as experimental activities. The work takes place in a process of construction and deconstruction, as the elements approximate, they form meanings and enable the understanding of the proposed research.
