Projects developments: working for the technical school and university integration

Abstract

In this article we present a research work developed with the groups of the mechanics students of the High School to explore the projects pedagogical practices. For the technical students too It is necessary to give opportunities for qualifies them to create, to judge and to development any project, since your original idea, until the operation of the products. Thus, we worked the mechanics of the harmonic motions under the softened and forced oscillations conditions, and several technological applications. These problems are precariously explored in the didactic books and laboratories. Like this, we proposed to project and to make a prototype of an oscillator that allows to explorer all the relationship of the variables and the dynamic situations which the subject to can provide for understanding the sciences of the mechanical oscillations. The work was realized by including since its conception on the general plan, and the dimensional shipping of the parts, and drawings in Auto-CAD software, until the operation of the mechanisms. The work still included the making of the mechanical components. The oscillator constructed is a mass-spring system, with backup for the operation. It allows to study, since the simple harmonic motion until the effects of the external forces to the under-critical, the critical and the super-critical attenuation. The results allows to correlate the different variables and respective scientific-technological meanings, associating the physical parameters with the consensual mathematical models. The essence of this proposal was to present the challenge for learning sciences from the technological projects developments.
