This is a short (10 min 34 sec) made for young teachers that defines the three different terms and some examples for how to teach each element.
This information is important for parents for struggling readers as well, because things go awry in reading in all three domains.
This video shares basic information about some terminology surrounding the teaching of emergent and beginning reading. It focuses on the definitions and distinctions between phonological awareness, phonemic awareness, and phonics.
In a nutshell:
Phonological awareness is the broader awareness of sound and is auditory.
Phonemic awareness is the awareness of the smallest units of sound in a word and the ability to segment, blend, isolate, and manipulate those smallest individual units of sound. It is auditory.
Phonics is the relationship between phonemes and graphemes. It is learning the rules and patterns of the letter-sound relationship.
