O ensino-aprendizagem-avaliação de concentração de soluções químicas através da resolução de problemas

Abstract

This research aims to investigate the potential and contributions of adaptation the TeachingLearning-Assessment Methodology for Mathematics through Problem Solving (MEAAMARP) to promote a teaching approach that allows students to take an active role in building knowledge about the concepts of the subject Concentration of Chemical Solutions. The specific objectives include the adaptation of MEAAMARP to MEAAQuARP, the creation of a collaborative, active and constructivist learning environment, through experimental problem generators and the construction of MAPEQ - Pedagogical Support Material for the Teaching of Chemistry. The Problem Solving methodology is a structured approach that involves students in building knowledge and skills, which provides a suitable environment for teachers to use in the classroom or laboratory. As for the adapted methodology, the students interacted in small groups to solve problems in a collaborative, active, inclusive and efficient way, which demonstrated a sense of responsibility in the face of everyday challenges. Through plenary discussions, the students were encouraged to understand the concepts, dialoguing with everyday contexts. The content worked on using the experimental problem-solving methodology developed in the school laboratory acted as a facilitator for learning the subject's concepts, as well as having a positive impact on the social, environmental, healthy eating and sustainable awareness of the students involved. In this process, assessment played a fundamental role in enabling observation of the lesson and offering guidance to the teacher to enhance their actions for successful learning, as well as allowing interventions when failures and/or difficulties in the learning process were detected. Through the development, validation and adaptation of the experimental problem generators, it was possible to build an Educational Product, MAPEQ, entitled: Exploring Knowledge through Problem Solving and Experimentation. This material will offer teachers guidance on using MEAAQuARP and the student notebook, with contextualized activities, motivating and awareness-raising vídeos as well as pictures and links to information. In this way, we hope that the material will be useful for both students and teachers, as the contextualized activities, carried out through practical experiments, promote participation and motivation in chemistry classes. Teaching strategies that promote motivation and engagement can favor the acquisition and retention of chemical knowledge.
