Raising and Educating a Deaf Child

International experts answer your questions about the choices, controversies, and decisions faced by the parents and educators of deaf and hard-of-hearing children.

Question from A.C., Vermont

I am looking for research based articles on Evidence Based Practices to teach literacy to children who are deaf. We are currently using multiple interventions one of which is Visual Phonics. I cannot find any research to support this as an evidence-based practice. Do you have any resources or suggestions?

Depending on the age of your students and their hearing abilities, Visual Phonics may be an effective strategy to improve your students’ phonological awareness skills and ability to sound out words. However, the long-term relationship between Visual Phonics instruction and decoding is unclear. Narr (2008) discovered that the number of years Visual Phonics had been part of instruction did not correlate with the decoding abilities of these readers.

Two other instructional strategies that you may consider if you have older readers or those with little functional hearing are: lexicalized fingerspelling and morphological instruction. Lexicalized fingerspelling is rendering the fingerspelled word smoothly. The fingerspelled word looks more like a fingerspelled loan sign. During instruction, the sign, lexicalized fingerspelling and the printed word should be presented simultaneously to the students. Later, the students can link the lexicalized fingerspelled word to the printed word (Haptonstall-Nykaza & Schick, 2007) more reliably.

Morphological instruction includes teaching affixes and root word meanings and the rules for combining morphemes as part of daily literacy instruction. Morphemes are the smallest part of the language that retains meaning (uni + cycle = unicycle). Morphemes tend to be spelled the same across words even when they are pronounced differently (magic vs. magician). Teaching DHH students morphemes and their meanings allow them to read using patterns that are accessible through the printed word. The students can break down the word into its morphemes, determine the meanings of the morphemes, and reconstruct the word to determine the word’s meaning (Trussell & Easterbrooks, 2015). Morphology instruction gives the students the tools to decode the words for meaning and improves their reading comprehension through vocabulary (Nunes, Burman, Evans, & Bell, 2010).
