Classwork
I hope that teachers would use a teachers version of the software, where the audio would be saved along with the notes that he/she had given in class. These would be projected to the class through a front projector in a class or optionally through a wireless network within the class to all students. Teachers would have the option of going through the problem sets and assigning which they wish their students to complete. These problems could be assigned to be graded without presenting the solutions, graded based on effort of trying them without looking at the solutions (based on time or not), or just by completing them. By solution, I mean to suggest that there are many systems in place to give hints on certain spots. Teachers will also have the option of marking certain sections or "questions towards more detailed informations" as mandatory, optional, suggested, etc.
