This study brings together key research issues in design collaboration and education for children. The research described here includes software design and empirical studies with participants. The conclusions are positive even though future testing will be necessary to achieve  conclusive  results.  The  multi-user  VR  games  looks  promising  to  foster collaboration  in  informal  education.  Designing  a  Collaborative  Educational  Immersive Playground  is  a  research  project  for  children  under  12  years  old.  The  exploration  of empathy and collaboration is important at an early age of the children’s development, although with VR, the environmental dimension is not well known and developed for this target group. This thesis explores the differences by designing in a physical and virtual environment and the improvement of those worlds for the final design of a virtual game that influence positively on collaboration and social skills in real life.
