Description

Reading fluency is reading text accurately, at an appropriate rate and smoothly, whether silently or aloud. It rests on the word-level skills beneath it: decoding, orthographic processing, phonological processing, morphological awareness and an understanding of syntax. It is measured by counting words read correctly within a time limit and by having students read passages aloud, scored for accuracy and rate.

The LVN record is written for grades 7 to 12. Fluency is described as reaching its developmental peak in the later elementary years and as not usually being taught explicitly in middle and high school, so adolescents whose fluency did not develop, including many with dyslexia, can face a persistent obstacle: fluent reading lets a reader attend to meaning rather than to working out words, and critical and disciplinary reading depend on it.

It is part of the wiki's broader reading and language page, whose central point is that effortful word reading uses the capacity comprehension needs. Dyslexia is covered under learning disabilities.

Implications

Context

• Matters in secondary classrooms where content learning runs through text and fluency is no longer taught explicitly.
• Background knowledge may help weaker readers understand text more fully.
• Reading fiction and other print exposure are associated with better fluency.

Target Learners

• Adolescents in grades 7 to 12, especially those with dyslexia or weak word-reading skills.
• Learners with high levels of inattention, or with low emotional well-being and motivation, who tend to read less fluently.

Target Learning Objectives

• Reading comprehension.
• Critical and disciplinary reading.
• Silent and oral reading rate and accuracy.

Related Learner Variables

• Prior Knowledge: background knowledge may help weaker readers understand text more fully.
• Academic and Critical Literacy: critical and disciplinary reading depend on fluency that frees attention for analysis.
• Syntax: understanding sentence structure is one of the components of fluent reading.
• Vocabulary: vocabulary knowledge may predict baseline fluency.
• Auditory Processing: perceiving speech sounds supports the phonological processing fluency needs.
• Attention: students with more inattention often read less fluently.
• Executive Function: inhibition may help suppress similar words during decoding.
• Long-Term Memory: fluent reading draws on written word forms stored in long-term memory.
• Processing Speed: processing speed becomes a more important part of fluency as adolescents' reading develops.
• Working Memory: verbal working memory supports decoding by holding and updating information while reading.
