I agree with you mrz about the spread of developmental abilities children have, and that it takes some longer than others to reach the 'destination', but it is true that some countries have a different way of looking at the situation. For example in France all children are expected to be working on the same thing at the same level as it is considered to be 'fair' and 'equal' to all children, whereas it isn't seen as acceptable practise at all in the UK. I think this is what the report is pushing towards:
8.6 A distinctive feature of some of the high-performing systems that we have examined in the course of the review appears to be a radically different approach to pupil progression and to differentiation. Crude categorisation of pupil abilities and attainment is eschewed in favour of encouraging all pupils to achieve adequate understanding before moving on to the next topic or area.
Achievement is interpreted in terms of the power of effort rather than the
limits of ability. The emphasis on effort is particularly marked in the Confucian-heritage countries such as China, Hong Kong SAR, Singapore, South Korea and Taiwan. The assumption here is that deep engagement with subject matter, including through memorisation where appropriate, leads to deeper understanding. In Western countries, especially in the US and England, the assumption has often been that capacity to learn, and achieve, is determined by innate endowment of fixed intelligence (ability). This assumption ? that there are limits on what children are capable of learning ? has had negative influence on expectations of achievement and how learning and assessment is organised
It then goes on discussing the various pros and cons to this approach (and having read it a second time I'm not sure what the overall conclusion is!) but then says this which is interesting:
For example, ?holding the group together? is a key feature in Singapore, where around one quarter of children enter primary school with no experience of formal pre-school settings. These children are frequently assigned to special classes of between five and eight pupils, and are taught by highly skilled and qualified specialist staff with the aim of bringing them up to a level of understanding which enables them to be re-integrated into mainstream groups as quickly as possible, giving a more even spread of attainment in teaching groups.
Not sure if this is a good approach or not, but it is interesting! As I said there are cultural reasons underpinning why we currently differentiate as much as we do in England, and believe it to be good practice to do so. I actually don't know that moving away from this would lead to higher levels of achievement across the board - I think all the other factors in other countries that supposedly do better than us have just as much impact.
Sorry for the long waffle, finished doing my masters but I still enjoy mulling over these sort of issues, and this seems a good outlet!
