This year, before we started to have lessons, I took part in a workshop about the implementation of ICTs in the teaching of English. We (teachers of English from different provinces in the country and I) participated cooperatively for this workshop in the virtual classroom of educ.ar. This platform is very similar to Moodle, it is really user-friendly, but, in my opinion, nicer.
During the five weeks that the workshop lasted, we worked with other people and we got to know many interesting tools, because that was the idea, to enrich our knowledge about softwares and websites that could be use in the classroom with or without access to the internet.
One great finding was this link: http://docentesytic.wordpress.com/2011/05/21/150-herramientas-gratuitas-para-crear-materiales-educativos-con-tics/,
