Every Thursday at 8PM EST, language teachers get together on Twitter and, using the hashtag #langchat, share ideas with each other.
The topic on August 29th was rubrics. See a summary of the discussion at http://blog.calicospanish.com/2013/09/03/creating-effective-rubrics-for-various-world-language-tasks.html
