[wiki-research] Spanish educational wikis?

[Beat Doebeli Honegger (FHNW)]

Hi,

In 10 days I will be giving a talk and a workshop about wikis in education
in Spain. Although I have experience with wikis in several education
settings (graduate school, undergraduate school, high school) and can
provide a lot of links and literature with research, tips and examples,
there is one big disadvantage: My material and education wiki examples are
mostly in German :-( (http://wiki.doebe.li/Beat/WikiInSchool).

Because I don't speak Spanish (there will be translation...): Could somebody
help me out with links to educational wikis in Spanish, that are world
readable and Spanish literature about wikis in education ? 

Thanks!
Beat
