OK, one more try.
On the back of dd's JP Yellow Level reader reading book, amongst the blurb it says;
'Light type is used for those few letters that should not be sounded out, such as the (b) in 'lamb'. There are also a few 'tricky' words, in which light type is not used, as children should learn them by sight. The tricky words introduced at the Yellow level are shown at the end of each book'.
Which probably explains why I am still confused about the tricky/sight word issue.
I was so surprised by this that I got in touch with Sue Lloyd. This is what she had to say about the blurb on the reading book:
When the reading books were published in 2001 it did say that the tricky words needed to be learnt by sight. Sara and I were not shown the blurb on the back until they had been published. On the next print run, in 2003, the wording was changed (after we had objected to calling them sight words) to 'As before, light type is used for those few letters that should not be sounded out, such as the in 'Lamb' ( but not in the new tricky words, which should already be familiar without this help).
So it looks as though you have an older edition of the reader. However, it is damaging that there are JP books around that say that. But it is clear that neither Sue nor Sara would endorse that statement.
(I didn't ask her about the video, though, mrz)
