'And what is wrong with the Clackmanshire study and other research into the effectiveness of SP?'
How much time do you have?
'Synthetic Phonics and the Teaching of Reading: The Debate Surrounding England's Rose Report' by Dominic Wyse and Morag Styles in Literacy Volume 41 Number 1 April 2007.
The authors discuss the Clackmannanshire Study's flaws and conclude:
- Controls for children?s levels of prior attainment and development lacked rigour.
-The socio-economic backgrounds of the children were not adequately assessed.
-Very little information was given about the schools: for example, their effectiveness.
-The experience and effectiveness of the people implementing the programmes was not adequately controlled.
- Experiments 1 and 2 were not valid comparisons of the synthetic phonics teaching method versus the analytic phonics teaching method because the different groups were taught different amounts.
- Reading comprehension was not significantly improved by the synthetic phonics approach.
In addition, the children studied tended to be about six months older than English students at a comparative stage.
The authors point out that
'The majority of evidence in favour of systematic phonics teaching refers to children age 6 and older. Twenty out of the 43 studies covered in the Torgerson et al. (2006) and NRP meta-analyses were carried out with children aged 6?7. Only nine studies were carried out with children aged 5?6. No studies were carried out with 4-year-olds. The idea that children younger than five will benefit from a systematic phonics programme is not supported by evidence and is arguably one of the most controversial recommendations of the Rose Report.'
(In the current UK context, teaching phonics means teaching phonics to 4 year olds, based on the Rose Report recommendations. This will be a massive experiment.)

'And why does your data fail to analyse the effect of specific educational methods on the learning of deprived children, when it recognises that education can have an impact on their life chances? Isn't your data incomplete?''
What I have provided is links to different studies, and a perusal of Torgerson shows that different studies look at different things.
What Torgerson also shows is that studies may be compared in a systematic way that can yield solid indications, and among their conclusions was the following:
'Since there is evidence that systematic phonics teaching benefits children?s reading accuracy, it should be part of every literacy teacher?s repertoire and a routine part of literacy teaching, in a judicious balance with other elements.'
