In April, we covered the DonorsChoose.org Hack Education contest, where developers were challenged to create apps and data visualizations with the DonorsChoose API that would engage the public and have an impact on education. Out of over 50 apps, an email mashup was named the top choice, with its developer receiving a trophy from political comedian (and DonorsChoose board member) Stephen Colbert.
iKnow, a social learning site launched last month by Japanese company Carego, have launched an API (our iKnow profile) to allow third parties to "add a little Learning and Linguistic magic to [their] applications, widgets and other mashups." iKnow allows users to take virtual English and Japanese language lessons (other languages are promised for the future) and guides and tracks their progress. Through the social component users can share their progress with friends, leave comments, keep journals, and compete for rankings.
