A importância do uso de experimentos científicos para o ensino de Ciências no Ensino Fundamental: Um estudo de caso

Abstract

The objectives of this study were to analyze whether teachers are working with practical classes using scientific experiments in science teaching, to list the reasons why science classes in elementary school have few experiments and to propose improvements for a better effectiveness of classes, taking into account view the benefits of practical classes in teaching learning. To achieve the objectives, a quantitative methodology was used through a questionnaire for data collection at a school in the Municipality of Grajaú-MA, 148 students from the 8th and 9th grade answered the questionnaire. The results obtained are displayed in the form of graphs, in which it was possible to notice that students like classes with experiments, however the school has no structure so that students can practice this type of class more often. It is concluded that the practical classes with scientific experiments have been applied even if little and that this index of classes can increase a lot, being necessary measures for this to circumvent or alleviate the problem of not having adequate structure and equipment in the school for classes with experiments . One way to improve the current situation is the partnership between the school that was the object of study and higher institutions that can help with equipment or technical visits.

Virtual Chemistry Laboratory: a didactic alternative to the teaching of Organic Chemistry

“…Experimental activities can serve as a powerful stimulus, impulse and incentive to awakening or maintain student interest in the contents worked in the classroom and consequently enhance learning (Gonçalves & Goi, 2020;Laburú, 2006;). These, for the most part, believe that science experiments increase the efficiency of learning (Faria et al, 2020). White (1996) also claims that these activities predispose students to construct new knowledge, acting on the emotional segment of their mental structures.…”

Convergência dos Planos de Ensino ao Projeto Político Pedagógico, quanto às metodologias de ensino

“…Além destas atividades menciona-se, também, o experimento. No entanto, de acordo com estudo realizado por Faria et al (2020), as aulas práticas com experimentos científicos poderiam ser ampliadas, a partir de parceria entre a escola e instituições de ensino superior, com a possibilidade de fornecer equipamentos ou proporcionar visitas técnicas, pois a principal dificuldade encontrada pelos professores, na aplicação de experimentos em sala de aula, é especificamente os recursos e condições que a escola não oferece. Constatou-se, também, que os alunos têm uma visão de que os experimentos de ciências em sala de aula aumentam a eficácia do aprendizado da disciplina.…”
