Many are the definitions to be found in different and varied authorized materials on what a WebQuest is, and many are its names, as well: “Treasure Hunt”, “Scavenger Hunt” o “Knowledge Hunt”, and in Spanish, “Búsqueda del tesoro” or “Caza del tesoro”. No matter its designation. What we, in the end, state is that when referring to a WebQuest, we are defining pieces of work to make an oriented use of the Internet as the main source in this sort of project work, so as to foster learning on behalf of the students –why not, on the educator, too?. The purpose of this article is to show that WebQuests can be perfectly applied in the EFL class at primary school, with the backing up of many known authors and investigators.
