EducoPark lets you write about a “life lesson” you learned and how you learned it, as well as begin an online discussion on challenges and how to face them. Users can leave comments on these lessons, and vote on which ones were most helpful.
I didn’t see anything particularly inappropriate for the classroom in a quick review of the site, and it seemed pretty interesting. I think it might be a good place opportunity for students to share their own “life lessons” and comment on others.
I’m adding the site to The Best Places Where Students Can Write For An “Authentic Audience.”
