I ran into the twitter page for the Montessori Middle School of Louisville today. It is regularly updated (as of May 2010) and the tweets give a fascinating glimpse of what a rural Montessori school near Knoxville, Tennessee, is up to. They have everything from programming computer games with Flash to working the gardens and composting.
The school’s website is at: http://www.discoveret.org/mms/ and they also have a blog at http://montessorimiddle.blogspot.com/
