Using Decodable Text - Bruce Murray, Auburn University

Decodable text is simply text matched to the correspondence knowledge of
readers. The words in decodable text (except for a limited number of high
frequency function words) are restricted to spelling patterns that the
reader can decode given his or her existing correspondence knowledge. This
means that a crucial factor in determining the decodability of text is the
reader’s current knowledge of correspondences. Even so simple a text as A
Cat Nap (Educational Insights) is not decodable for pre-alphabetic
children. A text featuring long a patterns, such as Jane and Babe
(Educational Insights), is not decodable for children who have only worked
with short vowels. On the other hand, Frog and Toad Are Friends (Lobel,
1970) is decodable for children who have worked with the major vowel
digraphs and who have acquired enough sight vocabulary to read at a
first-grade instructional level. For skilled readers like ourselves,
virtually any English text is decodable.
