Phonics and Decoding Can Be an Underlying Cause of Difficulties With Fluent Word Reading
Difficulties with fluent word reading can stem from different underlying causes. Lack of knowledge of the sounds associated with letters and letter patterns will result in weak decoding which can contribute to difficulties with fluent word reading, and in turn, often cause problems with comprehension.
How Problems With Phonics and Decoding May Present
Children might display difficulty with:
- discriminating letters from each other (e.g., b and d)
- matching sounds with the corresponding letter(s) and letter patterns
- spelling
- sounding out words; may tend to guess at words based on first letter or pictures or may substitute a familiar word when encountering an unfamiliar word
- reading fluently
Underlying Causes of Difficulty With Phonics and Decoding
Possible underlying root cause(s) of difficulty with phonics and decoding include:
- lack of explicit and systematic instruction and adequate practice with phonics and decoding
- instruction that prioritizes alternative "cues" for reading words, such as predicting the word based on the first letter or the picture
- a core weakness with orthographic processing (Moats & Tolman, 2019)
- difficulty with phonological skills, which then impact decoding skill, stemming from either a lack of instruction and practice or a core phonological deficit (i.e., dyslexia)
Preventing Problems With Phonics and Decoding
- Many children who experience problems with phonics and decoding did not receive explicit instruction in the letter-sound correspondences of English. For many children, problems with phonics and decoding can be prevented with strong core instruction, that includes a pre-determined scope and sequence for teaching letters and spelling patterns, ample practice with each new spelling pattern, and opportunities to read newly learned patterns in decodable text.
- Because phonics and decoding issues often stem from underlying difficulties with phonological skills, strong core instruction in phonological awareness can also prevent future problems with word reading.
Approaches to Intervention for Students Who Have Difficulty with Phonics and Decoding
Intervention is necessary when children do not make adequate progress with phonics and decoding skills even after receiving strong core instruction with opportunities to practice the phonics skills and decoding strategies they have been taught. It is important to determine whether a difficulty with phonics and decoding is stemming from an underlying problem with phonological skills before proceeding with intervention. Classroom-based intervention research has shown that effective interventions can lead nearly all children to develop proficient phonics and decoding (Gersten et al, 2017, Denton, 2012).
