Experimentação de baixo custo aplicado ao ensino médio como facilitadora da aprendizagem significativa

Abstract

With the expansion of education, the school has become an environment of diversity. Government policies in recent decades have generated a school formed by diverse cultural groups (Indians, Quilombolas, people with specific needs, among others) and it is the school's duty to integrate these groups. Often, the more rigid school curriculum makes this integration difficult, treating all students as equals without observing the learning particularities of each student. What also permeates the teaching figure, teachers with dense workloads, crowded classes and, sometimes, unprepared to deal with such diverse environments, cannot help effectively with the learning particularities of each student. The teaching of Chemistry is still practiced in a purely traditional and decontextualized way, which favors a demotivation on the part of the student. The present study evaluated the role of experimental chemistry classes using low-cost materials in the learning of 3rd year high school students from a public school in Paulistana state of Piauí, with the objective of applying low-cost experiments. It was observed that the application of experimental activities provided greater learning, arousing greater interest in the discipline and greater assimilation of the content presented also in the theoretical format
