This reminds me of one of my first year university maths classes.

With two weeks to go, the class was getting a bit restless and a few people where mucking up throwing paper air planes.

Unfortunately one stray plane smashed into the blackboard nearly hit the prof in the back of the head.

The lecture theatre went deadly silent. The prof turned around, collected his notes, wished us all good luck in the upcoming end of year exam and walk out of the lecture.

He also went M.I.A. for the remaining four lectures in the two weeks that followed.

But he got his revenge, by setting one of the hardest first year maths exams, which ended up having an average mark well below 50%.

So many people failed the faculty had to lower the pass mark.

Never understood why lecturers/professors take so much offense. Well if people are throwing paper air planes in the air you should be convinced that either everyone in the class is totally disinterested in math(which is impossible) or something is wrong in the way you teach.

Thinking back on those lectures, they were a bit on the dry side and as there was a lot of restlessness during the lectures.

Also the paper planes had started to appear in earlier lectures and the prof did pretty much ignore them.

I think it in this instance it was the plane crashing into the blackboard (and making a pretty loud thud) only inches from his left ear that finally made him snap.

I think its a politeness thing really - 9 times out of 10 the lecturer does not want to be there, rehashing the same boring old material again and again, and would much rather be working on their latest project. But they have to be there - you as the young student don't. If you are uninterested, leave. If you find the presentation boring, empathise.

IF YOU ARE UNINTERESTED, LEAVE!
