Reading is a key skill for success in school as well as for existence in today's society, casting its influence on education, employment, and social activities. However, for young children, taking the first step towards reading can feel like an uphill task. This is because a child might find it easy to recognize individual letters but combining them into sentences can be overwhelming in the beginning. Moreover, the process of reading requires the brain to juggle many tasks at once, such as recognizing letters, connecting them to sounds, and understanding the meaning of those sounds.
The English language poses unique additional challenges, as spellings are not always straightforward. The same combination of letters can produce different sounds (like "ough" in "though" and "bough"), and some sounds have multiple spellings ("see" and "sea"). This is where decodable texts come in. Decodable texts are designed to help children improve their reading skills by focusing on transparent letter-sound relationships they have been taught. These texts assist beginning readers in decoding words by breaking them into familiar sounds and blending them together.
However, critics believe that decodable texts do not offer enough exposure to authentic reading material, potentially leading to a narrow focus on decoding rather than comprehension. To explore this issue, Professor Dennis Murphy Odo from Pusan National University conducted a meta-analysis to gather evidence on their effectiveness in facilitating reading. In his new study published in the journal Literacy on 3 May 2024, Prof. Odo analyzed how decodable texts impact early reading skills.
The meta-analysis revealed that the average standardized mean difference (measured as Hedge's g: a measure of effect size) for word reading was small (g=0.20), while it was moderate for pseudoword decoding (g=0.30). This highlights how decodable texts can facilitate word reading and decoding to some degree, but they need to be used in combination with other reading instructional materials.
"The small to moderate effect sized indicates that decodable texts can have a meaningful impact on reading skills, especially in decoding difficult words, which is crucial for phonemic awareness and later reading success," says Professor Odo, while discussing the results.
