Today I learned that the least effective means of teaching is lecture.  I also learned that the human attention span is somewhere between 12 and 15 minutes.

I learned this during a 3 1/2 hour lecture, with no breaks.

The lecturer read the powerpoint to us.  The principal sat in the back of the auditorium to make sure no one left.  He actually had a bathroom pass.  One.  You had to take the pass and bring it back to go to the bathroom. 

Quality professional development.
