Avaliação fotocatalítica de nanoestruturas de ZnO obtidas pelo método solvotérmico assistido por micro-ondas

Abstract

Recently, we have observed a significant increase in interest in active and innovative methodologies in the field of education. It is clear that when students take on a central role in the learning process, they have the opportunity to develop new skills. Among these approaches, the Case Study method has gained prominence for its engaging and thought-provoking didactic proposal for students, differentiating itself from traditional teaching. This methodology involves the presentation of narratives that describe situations, real or hypothetical, that may have a connection with the students' daily lives. These situations require students to apply formal knowledge to resolve the problem. In this work, we will present an experience report that analyzes the implementation of a Case Study, in two different teaching contexts, during the duration of the Degree Program (PROLICEN-2021) and the Pedagogical Residency Program (PRP-2023). Our objective was to understand the students' perception regarding this methodology, with the environmental theme being common to both modalities. The first teaching modality refers to emergency remote teaching, resulting from the fight against the COVID-19 pandemic, in 2021 with 1st year high school classes, totaling 104 students. The second modality, returning to in-person teaching, was carried out in 2023, involving 3rd year high school classes, with a total of 175 students. In both teaching modalities, we observed notable interest and engagement on the part of students in the proposed activities. From an opinion survey, 71% of students agreed that they had developed the ability to solve problems. Furthermore, around 87% stated that the case study contributed to their learning in chemistry and 76% of students stated that they were interested in participating in new related cases. According to the good level of acceptance by students, in both teaching modalities, we can suggest that the case study combined with the theme of "Environment" is an attractive and motivating strategy for high school students and contributes to the learning of Chemical.
