Ever had a student ask a question that you just answered, not five seconds ago?

Of course, we all admit that no one (not even teachers) could possibly pay attention 100% of a 48 minute period. But that automatically means that at any given time, there is a chance that someone is not paying attention.

Go ahead --- try what you think are reasonable numbers and see what happens.

The moral of the story is that if teachers are going to lecture, they should expect to repeat themselves!


On average, each student pays attention % of the time
(with no decay, slow decay, or rapid decay.)
