  • It’s My Birthday Too, Yeah: I haven’t said anything about my experiences with Udacity’s Stat 101 class this summer, but this sort of thing is exactly what I was hoping it would cover. Why is it that you only need 23 people to have better than 50-50 odds of two having the same birthday? (Hint: 365x364x363x…342 divided by 365^23)

  • Lending App Developers a Helping Hand: A little over a year ago I was involved with writing a proposal to setup a center to support the dissemination of educational innovations coming out of NSF. Much of my contribution was getting us to move from the old fashioned model of dissemination, write a paper or hold a workshop, to something more modern. Even I didn’t really take it far enough. BetterApps is selling a service to evaluate an education app along 55 different criteria related to the design of the app for learning.

    Frankly, I’m not sure how they’ve priced it so it’s competitive for them to offer this service. I have run a courseware competition for the last 16 years, and have participated as a judge twice. In reviewing the courseware against our 11 criteria, I spend at least 2 hours with each submission. Even at “full price” they’re offering this service at $49.95 and have 55 criteria. I wish them luck.

    From EdSurge:

    After the assessment, the system tallies the responses and provides developers a report that scores the app in three categories: process (app design and direction), creativity, and 21st century skills (critical thinking, media and network literacy). To be clear, the service is about the design of an app, not its quality or educational value of its content.
