Two Sigma Improvement

I do enjoy a good provocative title.... "Education is failing technology" and this article by Mark E. Weston is both provocative and thought provoking.

I haven't posted anything on the blog for the last few weeks as I'm busy working on my first assignment but I thought this was worth sharing.

Weston sets out in his post a brief history of there work of Bloom and others in identifying ways for learning in a group setting to match the progress possible with one to one tuition. Many of the approaches referenced will be familiar to anyone who quotes Hattie from time to time.

Weston argues that the current set up in schools makes the burden of achieving that 2-sigma improvement (performing two standard deviations higher than their peers) too much about the actions of the individual teacher and not enough about the system as a whole.

People who listened to Professor David Hargreaves talk just about anytime in the last fifteen years would probably recognise the argument - as the students leave school full of energy and the staff stagger to the car park exhausted.

What I don't see in the article (and this is unfair as I don't think he set out to solve all the problems, just highlight them) are examples of the kind of technology education is supposedly failing, or even an indication of what that might be.
