Proposição de atividades investigativas com o tema ambiente e sustentabilidade no ensino de química

Abstract

In a context characterized by dissatisfaction and lack of interest in Education, the teaching/learning process is looking for innovative methodological approaches that can motivate students and arouse their interest in learning. Many researchers are dedicated to studying ways to overcome traditional teaching, which is based on student passivity and is still the only methodological approach used in many schools. To this end, an Investigative Activities Manual on Environment and Sustainability was developed to address the chemical concepts of the periodic table, solutions, concentrations, and organic functions, with the goal of making the classroom more interesting and stimulating for students. This material was structured in three didactic activities, developed in stages, based on the presentation of research proposals. The product was validated by expert judges from the chemistry curriculum, using a data collection instrument based on communication, conceptual and pedagogical axes to guide the judges' evaluation. The results showed that, according to the validation of the judges, the proposed activity manual is satisfactory and reaches adequate levels of quality and agreement in relation to the evaluation axes studied. The Manual of Investigative Activities was implemented with students from the 1st and 2nd years of secondary school in the subject of Chemistry, with the aim of investigating its effectiveness in the process of improving knowledge. Data collection included classroom observations, questionnaires, exercises, text production and student reports, integrating the entire educational process. As far as the students are concerned, the results obtained from the activities suggest positive engagement in the construction of knowledge related to the periodic table, solutions/concentrations and organic functions, through investigative activities, linked to the themes of environment and sustainability.
