What are some methods for delivering questions to players?
Maybe the original question is "overly broad"; I'll answer a related question:


  How can I implement academic drills into existing games?


Some games, such as "Jeopardy!", "Who Wants to be a Millionaire", "Are You Smarter...", etc. are already set-up for academic Q &amp; A. We can also adapt other games to fit this requirement. Off the top of my head:

Monopoly - properties are always auctioned (not bought), with the winner being the first player to correctly answer a question. 

Egyptian Rat Screw (played with a standard deck of cards): whenever a "double" or a "sandwich" occurs, the winner is decided by Q &amp; A (not by who slaps first/fastest)

Fore more serious games like Agricola, Power Grid, and Puerto Rico, you could require students to pass the "first player" marker left/right if they fail a Q&amp;A check. Of course, if they all fail, then the marker could work its way back to the original owner...
