I have always thought that it is a win win situation when I can have students do a puzzle or word game to help them learn new material. It is kind of like tricking them into learning, before they know it they learned something new despite in some cases what appears to be their best efforts not to. In the past I have used basic puzzles like crosswords or word searches. The more advanced games that this topic discusses intrigue me and I would like to develop a game to take the place of lecture. Do you think it is possible to replace some lecture time, in a one to one ratio, for concepts like ohms law application or lessons on engine management component identification? Not having played the games listed are some games better suited for some types of learning verses others (like concepts verses component identification)?
