What is Tracker?
There’s ShowMe, for example, which allows anyone — teachers and students — to create and share lessons via its whiteboard-like iPad app. (The company updated its app this spring, and at the time said that some 1.5 million lessons had been created with the tool.) And there’s Educreations, which offers a similar tool and raised $2.2 million in investment this summer. There’s the Web-based tool Sophia, which was acquired by Capella Education (parent company of the for-profit Capella University) in April. In August, former Flip (the video camera) execs launched Knowmia, a platform for “crowdsourced video lessons.”
