What are Decodable Books?
Decodable books and text passages are an important part of a structured literacy approach to reading instruction. Decodable books and text contain words made of letter-sounds, and spelling and morphological patterns (e.g. prefixes & suffixes) that a student has been explicitly taught. In order to make the text more readable, a small number of high-frequency words that have more difficult or unexpected spellings, such as ‘the’, ‘my’, ‘was’ are also used. As a student learns new parts of the alphabetic code the vocabulary used in the text expands to include the newly learned ‘graphemes’ and ‘morphemes.’
For instance, structured literacy programmes often start by teaching
- 5 short vowel sounds (e.g. /ă/ in ‘cat’),
- most common consonant letter-sounds and
- consonant-vowel-consonant (CVC) syllable type (e.g. ‘cat’, ‘pig’, ‘run’).
At this stage, decodable text provided for reading practice would only include those letter-sounds and CVC patterns, such as “The rat bit the pig. The bad rat hid in the tin can. The pig bit the cat”. Words like ‘any’, or ‘water’ would not be included because they include other pronunciations of the letter <a> that have not been taught yet. This is usually followed by words that include digraphs (eg. <sh>, <ch>, <th>) and consonant blends, such as ‘trip’, ‘glad’, ‘camp’, and some common suffixes (<-s>, <-es>, <-ing>, <-ed>). The consonant blends are often very challenging for students with dyslexia and require lots of reading practice which decodable books can offer.
It is important that the decodable text closely matches the sequence of instruction in letter-sounds, morphemes, phonetically irregular words, syllable types and spelling patterns that are taught throughout a structured literacy program.
Decodable Readers vs. Levelled Readers
Decodable text is quite different from ‘leveled readers’ which are used by many reading programs. With leveled readers, children are taught to rely on cues in the text or accompanying pictures to guess unknown words, and/or memorise a list of the most common words found in print. Often predictable and repetitive sentences are used to help students guess the correct words (e.g. “I get my ruler. I get my pencils. I get my shoes. I get my sweater. I go to school.”). Many words in early leveled readers require advanced decoding skills. For example, to successfully decode the word “pencil” a child needs to know that the letter <c> represents the /s/ sound when it comes before the letters <e>, <i> or <y>. And in the word ‘school’, the <ch> grapheme represents /k/.
When to use Decodable Text/Books
Using decodable text in the earlier stages of literacy instruction ensures that a student has the skills to read without guessing. They are especially important for students with dyslexia (or any struggling reader) because they provide reading practice using the knowledge of letter-sounds that are taught explicitly in a scaffolded approach. Reading decodable text helps students build fluency and gain confidence as they become proficient with word-level reading. Eventually, when most of the code has been explicitly taught, students will be able to read regular, more authentic texts. Decodable books are only needed until the student has mastered the code; after that, they can read anything!
