O vetorama como ferramenta de ensino-aprendizagem de conceitos de mecânica no ensino médio

Abstract

The main purpose of this research is to investigate the contribution of a game for the concepts of vector and vector magnitudes (position, displacement and average speed) learning-teaching. The game in question is called Vetorama. It is played on a sheet of graph paper, in which lines are drawn representing a winding racetrack, and the cars are represented by vectors, having initially the same intensity. As the game start, obeying specific rules, the winner will be the player who reaches the end with the smallest number of moves. The Personal Construct Theory had been chosen as methodological-theoretical basis to this research, witch was done with 25 students from the 1st year of High School of Camaragibe - PE. The methodology was structured considering the Experience Cycle five stages and involves a variety of didactic activities (game, questionnaires, exercise). The results had indicated that the Vetorama while methodological strategy improved the learning of desired concepts; sparking greater interest of students; allow greater socialization relations and allowed the identification of several difficulties in carrying out activities. The main difficulty encountered by students was the transposition of moves from the board to solve the exercises using algorithmic notation.
