Which phonics programmes?
* it should be based on the 44 sounds of English.
* we should avoid the ABC (26-letters, over-simplified methods) and the bucket-and-spade approaches to phonics (these use pictures that assume the wide vocabulary and extensive cultural knowledge of first-language learners)
* older learners need more mature materials
* sadly, very few such programmes exist
* materals for non-literate adults have a more mature approach to sound work, but they assume the vocabulary and cultural experience of first-language users
* adapt, trial, adapt - and be prepared to develop your own materials
I suggest internet searching using keywords such as 'articulation' or 'speech sounds'. This will take you to speech therapy websites which often have useful videos of sound-production and useful word lists, e.g. minimal pairs, initial sounds, medial sounds, final sounds, blends, rimes etc.
I also prefer to stay away from teaching materials that use the IPA (International Phonetic Alphabet) symbols. These are useful to me, and to very advanced learners, but they are really confusing to any learners who are already struggling with a new alphabet.
IPA use in Hong Kong schools is misguided, in my opinion. The IPA is a tool for the teachers - not the students. [One of my Hong Kong students called these symbols phoenix!]
I wouldn't recommend using Cued Articulation (or Jolly Phonics hand symbols), as all the hand-signing takes the learner's vision and memory-making away from the speaker's mouth. The most important factors are the
sounds themselves and the mouth movements that the speaker makes.
