Recent longitudinal studies of reading acquisition have demonstrated that the acquisition of phonemic awareness is highly predictive of success in learning to read - in particular of successful reading acquisition.
Programs for teaching phonics often emphasize rules rather than patterns and focus on "separate" sounds, called phonemes. In contrast, the most effective and efficient phonics instruction focuses children's attention on noticing letter/sound patterns in the major components of syllables: that is, on noticing the letter/sound patterns in initial consonants and consonant clusters and in the rime, which consists of the vowel of a syllable plus any following consonants, such as -ake, -ent, -ish, -ook (Moustafa, 1996).
Conventional blending and segmentation instruction improves the ability to manipulate phonemes. When instruction emphasizes phoneme manipulations, children learned what they were taught. In contrast, teaching beginners about phoneme identities does not seem to enhance phoneme manipulation skill.
