Plantas medicinais: uma proposta de metodologia a partir da aprendizagem baseada em problemas (ABP) no ensino de química orgânica

Abstract

The use of medicinal plants for therapeutic purposes has been passed down from generation to generation over the centuries. Addressing this theme in the school environment can be important for teaching, valuing the popular knowledge about plants brought by students to school, allowing interdisciplinarity. Thus, this research is based on analyzing a teaching methodology based on problem solving, based on the study of active ingredients present in medicinal plants, with the possibility of contextualizing the contents of organic functions, as well as the explanation of the use of medicinal plants. Having as main material of analysis, diagnostic questionnaires, participation and experiences of students from classes taught. In the first moment, we sought to identify and understand the level of chemical knowledge of the students in relation to medicinal plants. In the second moment, a problem situation was presented where the students sought its solution. And finally, at the last moment, a last questionnaire was made to identify the level of learning of the students when using the PBL (Problem-Based Approach). Contributing significantly to learning since it enabled students to have an active participation in the construction of their own knowledge, learning that they are able to think autonomously, instead of just memorizing and storing meaningless information
