Abordagem do tema meio ambiente no ensino médio a partir de casos investigativos

Abstract

The impacts generated by human actions on the environment is a transdisciplinary theme that is generally discussed in Chemistry Teaching. In this context, to enable discussions of this nature in class, it is necessary to use methods that promote students' autonomy, creativity, and interest, to provide opportunities for greater involvement in discussions on the subject. Thus, the present work aims to investigate the contributions of investigative cases to students' learning about the environment theme. For this, an investigative case was developed and applied, a variant of Problem-Based Learning (PBL), in a 1st-grade class of the technical course integrated into high school in agriculture at the Federal Institute of Education, Science, and Technology of Piauí (IFPI) - Cocal Campus. From the data analysis, we found that the case study method facilitated students' learning, in addition, it favored the development of skills related to critical thinking and decision-making. The results also indicated students' engagement to solve the case, demonstrating their interest in the activity. Therefore, we can infer that investigative cases have the potential as an innovative practice in Chemistry Teaching, capable of producing significant learning results
