Estudo da reação de saponificação no ensino médio: relação da atividade experimental como estratégia didática

Abstract

This research refers to the use of a didactic Strategy (ED) with the main objective of evaluating its contribution involving experimentation for the teaching of organic reactions to 17 students of the 3rd year of High School of the Integrated Technical Course of Electrotechnics of the Federal Institute of Education, Science and Technology of Goiás (IFG) -Câmpus Jataí. Questionnaires were used in the evaluation stages of this strategy. To this end, we sought to clarify the following question: "How can the production of bar soap contribute to the learning of saponification reactions with high school students?". The qualitative approach was used, in which participant research was chosen. As data collection instruments, questionnaires were applied to students, before, during and after the use of experimentation. For the evaluation of the collected data, content analysis based on the topics addressed by the students was used. Finally, it was concluded that the use of experimentation can contribute to the teaching of the saponification reaction, since the students had a better understanding of the saponification reaction when the entire process was conducted by them under the supervision of the researcher.
