I loved what Peter Garelja said at the Emerging Leaders' conference in the weekend. He was talking about the effect of ICT, and that in the hands of a poor teacher it really will have as little or no effect because 'a bad teacher with an ipad is a bad teacher with an ipad."
I remember thinking the same thing about the class size debate last year. A bad teacher with a small class is a bad teacher with a small class. I know that some countries have made the decision to go with bigger class sizes - NOT TO SAVE MONEY - but to give teachers more preparation time and time to engage in their own rigorous learning. This is a no goer of course but I can't help but add that a good teacher with a small class is a good teacher with a big class is a good teacher.
