The student voice is relevant and useful during the educational process, because it integrates theory, practice, and gives the students the opportunity to participate in their own learning. Additionally, it creates conditions and opportunities for students to develop or consolidate their own sense of being. Hence, the main objective of this study was to identify and analyze the beliefs and perceptions of high school students on the subject of physical education. The research is qualitative and was performed as a case study in Medellin, Colombia. It assessed the interest (enthusiasm) of students in the subject, their learning in the class, and how important the class was for them. The didactic process and behavior was included and the interaction of the teachers. Data was gathered via questionnaire, observation, and focus groups. The results show that students get a classical vision about Physical Education classes that includes a form of amusement, practice, change in routine from all other school subjects; and the inclusion of other aspects related to health and learning of sport. The conclusion of this research showed that one of main problems of the subject of Physical Education was the perception of students, as they reduce the contribution of Physical Education classes to the acquisition of motor skills. They were not aware of the wider benefits of Physical Education.
