Some edtech maths

Have been doodling on the back of a napkin this evening about edtech and its cost-benefit.

Let’s say a new technology is being introduced into your school, with the promise of “50% better learning for all”.

Let’s assume the following:

  • your class has 25 students
  • you teach them your lesson 4 hours a week for 30 weeks
  • each hour each student progresses on average “1 unit of progress” which we’ll call 1P.

Flipped Classrooms

Good News, Bad News

Students Love Technology

So, the good news is that Twitter can help students boost their grades. The bad news is that many students are device-o-holics.

Or perhaps it’s all bad news. Perhaps it’s just that students without Twitter lose marks because the Delirium Tremens they are wrestling with after being told they can’t use their phones makes it harder for the poor lambs to focus on the test in front of them.…

Connected and Un-Connected Schools

I think this point of Shelly’s is probably right.

A gap will emerge between those schools that can offer the capacity for network building — represented by their own network of connected teachers and administrators — and those that will not make the connection.

Technology adoption as an ethical issue

George Couros has an impassioned post here, about teachers and technology adoption. Especially liked Royan Lee’s comment

“When “You can be an effective teacher without technology” is an excuse, it’s an ethical issue.
