RESUMO

This work presents a contribution to the development of a strategy for improve the teaching/learning process in Mechanical Engineering courses. The applied methodology in this strategy was based on three major points: the creation of didactic tool applied to teaching in classes, the application of this tool in a "case test", and evaluation of the methodologys efficiency. The developed teaching tool consists of a sequence of problems involving dynamics of rigid body where the physical, mathematical and numerical modeling was presented in a systematic and progressive way of increasing difficulty. The problems were chosen among some mechanical structures well known by the students. This choice consists of a teaching strategy, which should motivate the student to know the structures behavior. In this approach, it was also taken into account, an increasingly problem complexity, so that the students were smoothly led along the learning process. In order to test the proposed strategy, it was applied, in a complementary way, in the Vibration course over a semester in the Mechanical Engineering Department of Universidade de Brasília. Due to its teaching qualities, the software from MathWorks MATLAB and its toolboxes were used. Finally, an instrument developed by Parasuraman et al. (1988), known as SERVQUAL, was adapted and used to measure the performance of the adopted strategy in the teaching/learning process. The results reached in this work show that the developed strategy of teaching is effective and contributes positively in the students learning process.
