O ensino das funções orgânicas e suas propriedades nos defensivos agrícolas presentes nas culturas de laranja a partir de uma abordagem CTSA

Abstract

The teaching of organic functions and their properties in agricultural protectionism present in orange crops from a CTSA approach. Chemistry teaching with a CTSA (science, technology, society and environment) focus allows students to acquire knowledge, skills, competencies and values necessary to form individuals aware of their role in society. The research investigated motivating actions for Chemistry teaching and learning process to promote the teaching of organic functional groups in a 3rd year high school class, using as a starting point the pesticides used in orange orchards. Data collection was based on the application of prior questionnaires and after the didactic intervention, in the visit to the Citrus Defense Fund (Fundecitrus) and also in the analysis of students' and research professor’s logbooks. Data analysis was carried out qualitatively through the definition of categories, in which it was found that the use of the CTSA approach in teaching organic functional groups combined with the agricultural pesticides theme, provided significant learning of the concepts worked on, in addition to the development of conceptual skills, procedural and attitudinal on the part of students. The engagement of students throughout the research and development of skills reinforces the importance of using teaching activities with a CTSA focus.
