Avaliação de propostas de recuperação paralela aplicadas na disciplina de cinética e reatores químicos

Abstract

The Kinetics and Chemical Reactors course is one of the main pillars of a chemical engineer's training, differentiated from the other unitary operations of a chemical process by Octave Levenspiel in 1974. Taught to students of the 5th period of the bachelor degree in Chemical Engineering at the Federal University of São Carlos (UFSCar), the course has 6 credits and 90h workload. The menu is extensive and complex, contemplating the topics of homogeneous and catalytic reactions in heterogeneous phase, chemical kinetics, analysis of kinetic parameters, calculation and modeling of ideal batch, continuous and semi-continuous reactors, among other important topics. The parallel recovery is based on applying punctual recoveries in all evaluative activities throughout the semester, so that the student has the opportunity to revisit a content that presents difficulties, recover the content lagged and have progressive gains throughout the subject; and presents several benefits, such as ensuring that all students finish the subject with the necessary understanding of the contents, leveling of the concluding classes, respect for the learning process of the individual, etc. Given the importance of learning the content of Kinetics and Chemical Reactors and the development of skills and competencies in this area, as well as the observance of high retention rates in this discipline, the objective of the present work is to present a proposal of parallel recovery for this discipline based on Method 300, created by Ricardo Fragelli, which consists of an active learning method and humanized evaluation that promotes maximum collaboration between students, in order to awaken a look at the difficulties and complications of each individual during the learning process. For the elaboration of the proposal, a case study was used that had already been carried out with a class of the subject offered in 2017, when the parallel recovery based on the 300 Method was applied experimentally; besides the follow-up and analysis of the parallel recovery applied in the class of 2020/1 that, because of the pandemic of the new SARS-CoV-2 virus (COVID-19), was offered in the emergency non-presential teaching form (ENPE). Thus, the proposal was elaborated for application in classroom teaching at a later moment, but this work followed and analyzed other applications of the parallel recovery in the class of the current semester. Thus, the proposal can be applied both in person and in hybrid, with activities both in person and at a distance, since the "new normal" is already a reality and the academic teaching structures will need to adapt to these social changes. The final proposal encompasses several recovery activities, which fit into the most diverse moments of the student's learning journey, and which promotes a more humane assessment and promotes a more solid and meaningful learning, which has much adherence to the profile of the student who is currently at university, both in the Kinetics and Chemical Reactors discipline and in other disciplines of the undergraduate course.
