Reading methods hinder writing
But there is a further complication: popular methods of teaching reading have not encouraged all the possible spin-offs into writing which should occur after the very early stages.
For example, good spelling is correlated with accurate attention to all the letters in words in reading and the need for such attention has often been layed down by reading theorists.
The National Literacy Strategy has not fully addressed this problem. In the additional literacy support video, for instance, we see a Year 3 child unable to read the word "soft", and a classroom assistant telling her to "look at the beginning" and then think about "what would make sense".
Sounding out all the letters in "soft" would have been a far more efficient way of reading it and would also have reinforced the child's understanding of spelling principles.
