Components of Dyslexia Instruction

    • Phonological awareness—“Phonological awareness is the understanding of the internal sound structure of words. A phoneme is the smallest unit of sound in a given language that can be recognized as being distinct from other sounds. An important aspect of phonological awareness is the ability to segment spoken words into their component phonemes” (Birsh, 2011, p. 19).
    • Sound-symbol association—Sound-symbol association is the knowledge of the various speech sounds in any language to the corresponding letter or letter combinations that represent those speech sounds. The mastery of sound-symbol association (alphabetic principle) is the foundation for the ability to read (decode) and spell (encode) (Birsh, 2011, p. 19). “Explicit phonics refers to an organized program in which these sound-symbol correspondences are taught systematically” (Berninger & Wolf, 2009, p. 53).
    • Syllabication—“A syllable is a unit of oral or written language with one vowel sound. The six basic types of syllables in the English language include the following: closed, open, vowel- consonant-e, r-controlled, vowel pair (or vowel team), and consonant-le (or final stable syllable). Rules for dividing syllables must be directly taught in relation to the word structure” (Birsh, 2011, p. 19).
    • Orthography—Orthography is the written spelling patterns and rules in a given language. Students must be taught the regularity and irregularity of the orthographic patterns of a language in an explicit and systematic manner. The instruction should be integrated with phonology and sound-symbol knowledge.
    • Morphology—“Morphology is the study of how a base word, prefix, root, suffix (morphemes) combine to form words. A morpheme is the smallest unit of meaning in a given language” (Birsh, 2011, p. 19).
    • Syntax—“Syntax is the sequence and function of words in a sentence in order to convey meaning. This includes grammar and sentence variation and affects choices regarding mechanics of a given language” (Birsh, 2011, p. 19).
    • Reading comprehension—Reading comprehension is the process of extracting and constructing meaning through the interaction of the reader with the text to be comprehended and the specific purpose for reading. The reader’s skill in reading comprehension depends upon the development of accurate and fluent word recognition, oral language development (especially vocabulary and listening comprehension), background knowledge, use of appropriate strategies to enhance comprehension and repair it if it breaks down, and the reader’s interest in what he or she is reading and motivation to comprehend its meaning (Birsh, 2011, pp. 9 and 368; Snow, 2002). 
    • Reading fluency—“Reading fluency is the ability to read text with sufficient speed and accuracy to support comprehension”(Moats & Dakin, 2008, p. 52). Teachers can help promote fluency with several interventions that have proven successful in helping students with fluency (e.g., repeated readings, word lists, and choral reading of passages) (Henry, 2010, p. 104).
