Hi there - I am a 7th grade SS teacher in CT. I am looking to find other schools to collaborate - in the US or outisde the US. I am using a site that I helped to build at SEEdebate.org. SEEdebate is free and safe for students because it is closed. Students can't sign up without teacher codes to use. They are then within the teachers' "class" which makes it easier for teachers to pull up their students' comments. The comments are moderated too. You can design any type of discussion you want, some use it for simulations, wikis etc. Also, it is just a forum if you want to have students discuss with others. Anyway - I would love to get my students talking with other students aged 11 - 14!! Please let me know!
