Experimentos de Química Analítica: análises volumétricas, em uma escola do ensino médio no município de Humaitá-AM

Abstract

The teaching of Chemistry in the high school and elementary school curriculum plays a crucial role in the student's educational development by encompassing aspects of nature's transformations through reactions in the physical world of matter. However, it is noticeable that there are still various obstacles related to learning and assimilating content, often presented through traditional lectures. Based on these premises, the research aims to enhance Chemistry teaching and learning in high school by implementing demonstrative experimental practices in analytical chemistry. It adopts methodological principles of field research with an experimental nature through demonstrations focused on volumetric practices, using qualitative and quantitative approaches. The target audience consists of 64 high school students in the 2nd grade of a public school in Humaitá, Amazonas. The research unfolds through comparative data between the pre-intervention questionnaire applied before the research and the post-intervention questionnaire after the volumetric practices, leading to the final analysis. Results indicate that an exponential number of students acknowledged the project's notable role, utilizing demonstrative experimental practices as an academic tool to enhance Chemistry learning. In this context, it can be emphasized that the demonstrative experiments yielded satisfactory results, sparking students' interest in scientific knowledge in chemistry, making theoretical concepts more accessible and engaging. This promotes formative development by incorporating new practices into the school context.
