I wanted to find out more about Class Dojo and a search came up with this article. I am still investigating wether we should have it for the school, I love the graphics? Watch this space

Hi there! Thanks for being eager to learn more about ClassDojo. Joe Bower was an amazing educator and will be dearly missed. This article, though, misses so much about the beauty of ClassDojo. Very simply, it completely ignores how ClassDojo brings millions of parents into the classroom with simple messaging (www.classdojo.com/messaging), and how over 500K classrooms have started teaching growth mindset because of a ClassDojo and Stanford University partnership (www.classdojo.com/bigideas). There’s so much depth to ClassDojo that it’s better to ask a teacher who uses it! Let us know if we can help by sending us a note: hello@classdojo.com

Thanks for replying to my post, I do know many teachers who use it and love it too, just thought the article was quite interesting.
