To break it down simply, it is teaching that places a real world emphasis on teaching. In other words, relating what is being taught into the context of the real world, hopefully with the effect of engaging the students interactively, and thus eliminating the questions of "Why do I need to learn this stuff?".
Included in this model is interclass project learning, or activities spanning from class to class, to emphasize the necessity of different skills needed to complete a project successfully, all the way down to a project report on the success of said activity.
In addition, the youth are learning valuable skills that place emphasis on so-called "real world" vocations such as computer and technology, health, business, etc.
