Byrne, B., & Fielding-Barnsley, R. (1991). Evaluation of a program to teach phonemic awareness to young children. Journal of Educational Psychology, 83, 451-455. In the study, children searched posters for the phonemes they were learning about. Here are their posters for /p/, /l/, and /t/. There are two posters for each phoneme, one for searching for words that begin with the phoneme, and one for searching for words that end with the phoneme.
