Investigation-action and the projects methodology in physical education: The organization of Prisoner's Base tournament

This article exposes an educative experience in the physical educational area by using the projects based methodology. The experience consists in the organization of the popular Prisoner's Base game. It was organized by 32 students in a prep course conducting to a Superior Grade (post-school studies that are only possible to do after getting "level A" or by passing this course) of a public school of Vallés Occidental, a Barcelona province. The experience is based in the action-research methodology. The event preparation, conducted autonomously by the students, lasted two quarters, in which they have to take care of all the necessary aspects for the optimal realization of the final event. The results obtained show that the project presents a powerful resource to achieve the competence-based curricular objectives. Besides, it presents a constructivist approach to didactic proposals of critic pedagogy, that locate the student in an affective scholar environment that grants them spaces of autonomy for the personal and academic development.
