Chronofencing is the principle of delivering contextually important information at the right time. It is like geofencing (triggers of contextual information at a location) but perhaps more useful. Learn to understand this term as it has important implications in education. For example, students can have triggers before leaving school reminding them what books to take home - or reminders of what to take to school - these time based reminders could be combined with location as with the iphone reminders.
Alfred Thompson shares information on the 2013 Imagine Cup - Bigger than ever. He's the one blog at Microsoft that I read on a daily basis and worth following. He's also a dear friend and speaks very highly of the great things he's see happen in the Imagine Cup.
There are some great things that are included in this year's contest including making an app that could change someone's life in the Wold Citizenship category. Make a game in the games category and in INnovation to "reinvent" something - social networks, shopping, music, etc. Those are the 3 competitions. If you're inventing and innovating in your classroom, consider joining in.
