The concept of Ball School Heidelberg was developed by Prof. Klaus Roth, Institute of Sports and Sports Science at Heidelberg University, Germany, in 1996. In 1998, the first Ball School courses were implemented in primary schools. All of the Ball School's programmes are scientifically reviewed, updated and fully differentiated. Ball School Heidelberg provides activity programmes for all children. It supports the children's motor development and hereby also includes kids with motor deficits as well as those who are highly talented in sports games. It was awarded in the innovation contest “Deutschland-Land der Ideen” (2009) and labelled “hallmark of excellence” by the platform for Nutrition and Movement (peb) (2003). Ball School Heidelberg is supported by the Dietmar-Hopp- as well as the Manfred-Lautenschläger Foundation. Concept - goals, content, methods Ball School Heidelberg is a non-profit institution with the objective of counteracting the children's ever increasing lack of movement. Children do not become specialists in one particular kind of sport, but rather all-rounders as they are trained in many sports through the holistic development of intellectual, emotional and motor skills. Playing with balls as well as the social integration within sports groups have priority – experiences children used to gain implicitly and without instruction on streets, football grounds and meadows. With its motto “from general to specific”, Ball School Heidelberg follows the basic philosophy of the integrative sports education. All sports games are seen as “family members” which resemble each other. Their similarities (modules) are singled out and taught comprehensively, i.e. non-specifically to a particular sports game. The aim is a broad fundament of basic, generalizable competences guaranteeing a fast and effective learning in all sports games. The Ball School's non-instructed teaching helps children to learn implicitly and to develop playing creativity as well as to achieve its overall goal of getting all children involved in physical activity. During Ball School lessons, children play with their feet, hands and sticks/rackets/bats etc., acquiring skills such as recognising gaps, determining paths to the ball and the ideal position of playing it or controlling the passing of the ball. The programmes’ curricula are based on four key principles for sports programmes for children: the principles of regarding the developmental stage, of versatility (goals), of joyful learning (content) and of implicit non-instructed learning (methods). Programmes - structure Ball School Heidelberg is an activity programme for children from 18 months to the end of primary school. This wide
