Experimentação no ensino de química: aplicação com materiais de baixo custo nas aulas remotas

Abstract

Chemistry classes are of paramount importance, but as we know, it is a discipline that requires a lot of attention and dedication just like any other, it involves theory, calculations and practical classes. Thus, the present work aimed to verify the result of the relationship of theoretical and practical classes with alternative materials for second year Class A, and the theoretical class for class B, from the high school Mr Manoel Rodrigues in the context of remote classes. This work was carried out in two classes of second year of high school of the school Mr Manoel Rodrigues, the classes were held through the Google Meet platform. For the second year class "A" the theoretical class was taught along with the availability of videos of the experiments, and for class "B" only the theoretical class, for both classes a questionnaire was conducted to compare the performance of the two. The results shown that the experimental activity was successful, because the class that received the use of the experiments together with the theoretical class had a higher percentage of correct answers. It is concluded that the lack of experimental classes in the pandemic caused a great negative impact on the student's learning, since the use of experimental practice in chemistry classes is of paramount importance given that they are more attractive and end up helping teachers when teaching the contents
