Quizzes

“Sometimes questions are more important than answers.”

Nancy Willard

Socrates use to make his students getting interested on a topic by answering questions. Asking questions is the only way to find the truth. I strongly endorse this view as the majority of the teachers does. On the web there are thousand sites for quizzes. I have tried many of them but here there are two quite useful in language learning:

BBC is one of my favourite site for authentic material. The learning English pages are extremely useful. There are many games that you can use in the classroom such a crosswords and beat the keeper(It's fun!). BBC's quizzes could be extremely useful in teaching idioms or colloquial expressions. Try it!

 
One of the largest quiz databases in the Web. You can find some really good quizzes of general knowledge and some of them , belive me, are really challenging! Quizzes come both in HTML and Flash form.
I really enjoyed a quiz about what is sarcasm!(For those of you that find it difficult to teach abstract concepts).  One drawback of this site is the advertisements(sometimes there are pop-up windows as well).
