Lesson

A lesson describes the actual task the user needs to solve. Every lesson has a specific Lesson Type which describes how the lesson is built and which elements it contains. The stucture of each Lesson Type is always the same while the content may differ.

A lesson can have multiple sub-tasks which are called Iterations. Every lesson has at least one of those Iterations. This enables a level to describe a task once and let the user solve it with different options. If he has to learn the vocals for example there might be an Iteration for A, another one for E and so on...
