I attended theEdTech4E (Education Technology for Export) conference in Wellinton on the 12th April. At this conference mention was made of the Pisa study which I had not heard of.
Although this is more to do with secondary school education none the less it sparked my interest and I found this talk by Andreas Schleicher very interesting. One of the points he makes about class size not necessarily being important sparked my interest as this was proposed recently in NZ and squarely rejected by the population. I have to say I was one of those opposed. Our government should have done a better job of explaining what it was they wanted to achieve through this and where these ideas had originated. had they done this they may have experienced less resistance to the idea. I can now see the rationale for this but still wonder if there is some cultural component to class size. Although larger classes work in some parts of the world does that mean they would work here? I agree that a great teacher who is aware of good teaching practice and is able to use up to date and relevant tools to support learning should be able to overcome many of these issues.
Anyway here is a link to the TED talk from Andreas. I look forward to hearing your thoughts on this in the comments below
