The book on truancy in practical Physical Education classes, portrays a pertinent discussion of the reasons why students are not interested in these classes, and within your reading of this monograph, you will find several occasions linked to the shift and counter-shift of the practices of Physical Education classes, hindering the work of the teacher and the main thing: the student's learning. However, the causes are not only the discrepancy between practical and theoretical classes, but also the teachers' methodologies, lack of materials and physical structures are some of the main points reported by the students of two schools located in Cariri do Ceará, more precisely in the city of Crato. It's a very clear reading and one that seeks to reflect the actions needed to mitigate this evasion and, consequently, devaluation of the discipline of Physical Education in the school environment.
