A study presented at the British Educational Research Association?s annual conference in Manchester was particularly useful in this sense, as 3,000 secondary school pupils were presented, last year, with almost identical questions to those a similar sample of children had faced back in 1976 and 1977.
And the results uncovered by this team of highly experienced academics from King?s College, London, and Durham University, were astonishing when one considers the transformation of secondary exam results over the same period, that there has been little change.
The questions ? taken by 11- to 14-year-olds in both eras, were divided into three, testing either algebra, ratio or mastery of the manipulation of decimals. In the last of these three categories, pupils appeared to have improved since the 1970s, perhaps reflecting the greater use of calculators and computers where decimal notation is to the fore, suggested the researchers.
But the 2008 pupils fared roughly the same on the algebra questions as they had in the 1970s. And on the fractions questions, they came off slightly worse than their predecessors of a generation ago.
