A utilização de materiais alternativos no processo de ensino-aprendizagem de Química

Abstract

This study focuses on the use of alternative materials and reagents in teaching Chemistry at a public state school located in Ipojuca, Pernambuco. Its aim is to investigate whether the use of these materials can facilitate the teaching and learning process of Chemistry for the participating students. The target audience was 1st-year high school students. To evaluate the effectiveness of the study, a questionnaire was administered regarding the experimental approach, which addressed the importance of acids and bases in our daily lives and the use of red cabbage pH indicator. Everyday materials such as water, lemon, laundry detergent, and vinegar were used for the experimental activity. It was observed from the results collected through the aforementioned questionnaires that there was an improvement in student learning and that the adopted methodology proved to be potentially interesting for teaching and learning chemistry. And according to the students themselves it is quite important the use of experimental activities in the understanding about pH, which was the content studied, and the phenomena of Chemistry, being a more significant means in the construction of knowledge of the sciences.
