Lançamento de projéteis no contexto dos ambientes manipulativos virtual e físico: percepções de um grupo de licenciandos em Ciências Exatas

Abstract

The theme of this work is related to Launching Projectiles worked in two types of Manipulative Environments (ME) - Physical and Virtual - and aims to verify the didactic potential of these ME in the perception of a group of academics from a Degree Course in Exact Sciences, from a Federal University in the state of Rio Grande do Sul. In the Virtual Manipulative Environment (VME) the virtual simulator 'Projectile Movement' found on the PhET Colorado site was used and, in the Physical Manipulative Environment (PME), a toy revolver that played the role of a projectile launcher. The activities, organized in workshops, were applied to a small group of academics. During the performance of practical activities, immediate perceptions about the occurrence of certain characteristic affordances of each ME were obtained via a questionnaire. After carrying out the virtual and physical experiments, the academics were challenged to identify and describe, comparatively, the limitations and amplitudes of each ME, including making inferences from the results of one in the other. It was noted that most academics envision the PME as an ME that best meets the proposed objectives, allowing a more adequate understanding of the physical phenomenon addressed.
