Spelling and Students with Learning Disabilities

December 2005

Students with learning disabilities in reading usually have problems in spelling as well. Spelling can be especially difficult for these students, for several reasons. First, the core deficit in reading disability (RD) typically involves word decoding, and many of the same weaknesses that impact word decoding in individuals with RD---such as poor phonemic awareness or poor knowledge of letter-sound relationships---also influence spelling. Furthermore, spelling is affected by independent reading and exposure to text; avid readers see more words in print and have more opportunities to learn spellings of specific words. Because individuals with RD are rarely avid readers, lack of exposure to printed words may adversely influence their spelling. Finally, English spelling is complex, drawing upon several different kinds of knowledge. Effective teaching of this knowledge is especially crucial for students with RD.

Spelling difficulties can be enduring in individuals with RD, sometimes even after reading has been successfully remediated. Addressing spelling difficulties is important, because poor spelling can hamper writing and can convey a negative impression even when the content of the writing is excellent.

Knowledge Required for Spelling in English

The most basic kind of knowledge required for good English spelling involves phonics knowledge, or knowledge of common letter-sound relationships. For example, children need to learn that the sound they hear at the beginning of the spoken word "bag" is spelled with the letter b, the medial sound is spelled with the letter a, and the final sound is spelled with the letter g. Unfortunately, however, basic phonics knowledge is necessary, but often not sufficient, for accurate spelling in English. Some familiarity with the printed word is essential for correct spelling of many words. This is true not only for phonetically irregular words such as of or what, but for many regular words as well. For instance, phonics knowledge serves as an essential base for spelling a word such as shirt, but the only way to know that the word is not spelled with ur (shurt) or er (shert) is to be familiar with the printed word. Morphological knowledge about root words and relationships among words is also important, especially as children progress to more advanced levels of reading and spelling. For example, the second vowel sound in the word colonist is a schwa (unstressed) vowel; it is impossible to hear that the vowel is an o rather than, say, an i or a u. However, if the child knows the spelling of the root word colony, this knowledge facilitates the spelling of the related word colonist (as well as colonial and colonize). All three kinds of knowledge---basic phonics knowledge, word-specific knowledge, and morphological knowledge---need to be addressed in spelling instruction.
