I always thought it would generate interest in students if there was a '?' (question mark) or an '!' (exclamation mark) in a title.
Only till I read the following: (Courtesy: Dear Blank, Please Blank)
Dear Teacher,
Please don't put ! in the titles - it irritates me because I dont know whats the fun in there!
Sincerely, your student!

Well, everyone is titled to his/her opinion.
