Meaningful Experiences in Physical Education and Youth Sport: A Review of the Literature

The purpose of this research is to review the literature about young people’s meaningful experiences in physical education and youth sport. We reviewed 50 empirical peer-reviewed articles published in English since 1987. Five themes were identified as central influences to young people’s meaningful experiences in physical education and sport: social interaction, fun, challenge, motor competence, and personally relevant learning. These themes provide future direction for the design and implementation of meaningful physical education and youth sport experiences. We also highlight the need for the development of pedagogies that facilitate and promote meaningful engagement in physical education and youth sport settings.

Educational technology as a key to educational innovation:

Instructional technology, especially the use of computers and the Internet has been lagging behind in the German educational system in comparison to other European countries. When this lack was realized in the second half of the 1990s it had quite a “shock-effect” but one of the healthy kind: Since then numerous public and private initiatives have been started to advance the use of technology in schools, higher education, and in vocational training. At the college and university level, there is a trend towards connecting online and offline courses. Also, it was understood that it is not enough to just provide schools and universities with the technology needed but that the introduction of technology has to be accompanied by profound systemic and structural changes. Thus, there is great hope that the use of technology in education will fuel educational innovations at all levels needed for educating and training pupils and students to act as responsible and media-literate citizens in a modern world.
