Previous research suggests that children who are successful in phoneme
awareness tasks also have high levels of alphabet knowledge. One conn
ection between the two might be alphabet books. Such books typically i
nclude both letter-name information and phonological information about
initial sounds ('B is for bear'). It may be that children who are rea
d alphabet books, and thus understand how B is for bear, will learn bo
th letter names and be able to isolate phonemes. To examine this, we g
ave three treatments to different groups of prekindergarteners. In the
first group, the teacher read conventional alphabet books. In the sec
ond, the teacher read books chosen to contain the letter names only, w
ithout example words to demonstrate sound values. The third group, a c
ontrol, read only storybooks. We found that ail groups gained in print
concept and letter knowledge over the course of the study. The conven
tional alphabet group made significantly greater gains in phoneme awar
eness than the group that read books about letters without example wor
ds, suggesting that conventional alphabet books may be one route to th
e development of phoneme awareness.
