Here's one for starters
From this report. a succinct description of the phenomenon:
'In the UK, social class has been a very longstanding analytic category associated with educational disadvantage, being related to propensity to stay in education after any compulsory leaving age, to educational achievement in examination results, and in entry rates to higher education.
Social class was in the UK traditionally categorised by the father?s occupational status: this has been amended in the past decade to a nine-point social class categorisation (the NS-SEC or National Standard Socio-Economic Classification), based on parental occupational code. There are persistent inequalities in educational outcome in the UK related to social class. However, these class inequalities also have a high level of correlation with family income. This is related to, but not only dependent on, occupational category.
Other factors of gender, ethnicity, disability and linguistic competence may also correlate with occupational category. Over the past century, there has been a consistent decline in the proportion of the population who are classified as belonging to the unskilled, manual and semi-skilled categories of employment: about 75 percent of the population were classified as in manual occupations in 1900, and about 35 percent in 2000 (Heath and Payne 1999). There has also developed a persistent group of the long-term unemployed.
The educational attainment of these groups tends to be below the national average in school, and more than 50 percent of a school?s performance is accounted for by the social make-up of its pupils. Butler et al (Butler et al. 2007; Webber and Butler 2007) found that in affluent areas 67 percent of 11-year-olds achieved level 5 in the national English tests and 94 percent of 15-year olds gained five or more passes at GCSE2 at grade C and above, while of children growing up in more deprived areas just 13 percent obtained level 5 in the national English tests for 11-year-olds, and only 24 percent of 15-year-olds achieved five-plus GCSEs at grade C and above (see also Reay 2006). Similarly, Archer and colleagues (Archer et al. 2003) reported that only 10 percent of entrants to University courses came from unskilled and manual backgrounds, while 58 percent were from professional and intermediate backgrounds.'
'because clearly those in the middle and at the top successfully learn to read using mixed methods.'
That just isn't true. My own ds failed to learn to read using mixed methods, albeit with scant attention paid to phonics, with no daily phonics session and more attention paid to learning sight vocabulary. With proper phonics teaching he is now at a 2c.
Feenie, your anecdote is, well, an anecdote. Unless you can prove to me that 80% of children who do learn to read in school do so using SP and not mixed methods, then your DS remains an anomaly, and the norm is for children to learn to read using all sorts of methods.
