I have already updated the links on my page about the use of webquests in the English class. It is a quick reference guide with some websites where you can get first-hand information about the use of this interesting teaching technique. I would also recommend to have a look at Isabel Perez’s site on this topic (a link on the left-side bar), she read her PhD dissertation on the use of webquests to enhace vocabulary acquisition.
