Decodable books provide the reading practice for phonics lessons. They include sound-letter relationships and word types learners have been taught, plus usually a few high-frequency words with harder spellings needed to make the book make sense, which are also pre-taught.
Decodable books would replace the widely-used predictable/repetitive texts, which encourage children to guess and memorise words, not sound them out.
At the moment, children might be learning about “i” as in “sit” in phonics lessons, but take home a predictable text that might contain words like “find”, “ski”, “shield”, “bird”, “friend” or “view”. Instead of helping kids practise the sound-letter relationships they’ve been taught, their home readers can undermine this teaching.
DVS’s campaign hit the statewide media this weekend, yay, with an article called “Dull, predictable: the problem with books for prep students” in Fairfax newspapers.
