Principal Sappenbottom and the Workshop Model
Assistant Principal Sappenbottom got a promotion: she was now Principal Sappenbottom. She got a raise, she got a bigger, more private office, and now she really could exercise her prerogative to do nothing as all she had to do was close the door and say she was in a meeting. She was the principal. Who was going to bother her? The students? They didn't even know who she was.
Principal Sappenbottom attended a Principal's Workshop in which she was told that the new educational model of learning was the Workshop Model. All desks now had to be arranged in groups and students worked together every day in those set groups. Ideally they would walk through different "workstations" as students progressed through the lesson.
This sounded good to Principal Sappenbottom. It was the New Thing. And so she sent out an edict that from now on, all lessons had to be based around the Workshop Model. AP's were instructed to give "U's" to teachers
