"The problem with phonics though, as a learning tool, is that English is very irregular and doesn't obey its own rules. I actually think that too much emphasis on phonics can hinder the learning process."
English is complex but that doesn't mean it is very irregular. There aren't any rules to obey in phonics.
In English we have approx 44 speech sounds (depending on accent) but only 26 letters in the alphabet so some sounds are represented by two, three or even four letter spellings. The problem is that in English some sounds have more than one spelling - day, make, great, eight, they, paid etc and some spellings represent more than one sound - meat, steak, bread. This means we need to know around 180 different spellings to read any word in the English language (alternatively we could attempt to memorise over a million words as wholes
) .
Whether we've been taught phonics directly or worked it out for our selves this is the knowledge we need to use to read (and spell). As proficient readers we don't even have to think about it ...until we meet new words. Without phonics we wouldn't have a strategy for tackling these effectively.
Now we have a choice - teach that essential information about our written language or leave it to chance that children will be able to work it out for themselves, which they might be able to do but of course that will take many years.
