This blog series, prepared under the auspices of USAID’s Office of Education, addresses some potential challenges and solutions to increase student literacy rates as they relate to a variety of disabilities in diverse global contexts. This blog provides an overview of the importance of exposure to sign languages for children who are deaf and hard of hearing (DHH) and offers guidelines for teachers and parents on how to read aloud to DHH children. This blog series spotlights different types of disabilities, and how they relate to children learning how to read. Related blog: Education for All Means All
Early exposure to any language helps support a child’s literacy development. All children, especially children who are deaf and hard of hearing (DHH), benefit from early exposure to a sign language. According to Ethnologue, there are more than 135 unique sign languages used by DHH communities worldwide.
Is spoken language the only way for children to learn to read printed words? Absolutely not!
But how does learning a sign language help with literacy development? How do children using signed languages learn to read?
The critical language acquisition window starts to close after age 3. During this time, the development of a strong foundation for language is crucial. Otherwise, the likelihood of a child facing a lifetime of stunted language abilities, including reading, increases dramatically (e.g., Allen, et al., 2014; Morford and Mayberry, 2000; Petitto, et al, 2001).
In particular, children who are DHH benefit from early access to a sign language because it’s quite accessible. This allows children to expand the size of their vocabulary, to bridge concept to meaning and to build a strong foundation for language. Through bilingual education, children have opportunities to bridge their knowledge, gained through sign language, to reading. Below are some research findings regarding language and literacy development from the National Science Foundation’s Science of Learning Center on Visual Language and Visual Learning at Gallaudet University:
❖ Communication & Social Skills. Children who use sign language have better and frequent eye contact with the caregiver or parents. This will help children learn more about the world around them while also gaining social skills. Knowing where to direct their attention leads to greater vocabulary knowledge, and these skills are the building blocks that lead children to being able to learn and communicate efficiently at home and at school.
For example, a recent study (Lieberman, Hatrak, & Mayberry, 2014) indicated that eye contact between DHH children and their mothers during book reading was much more frequent in the five-minute interaction compared to hearing children.
Number of shifts (looking at the book and then at the mother) per 5 minutes
Children using spoken language
5 shifts (@1 per minute)
Children using sign language
80 shifts (@16 per minute)
❖ Reading & Learning. Supporting children’s sign literacy helps them gain a solid foundation in a language and an advanced diverse vocabulary, which will in turn help them learn to read. With consistent exposure to a sign language and connecting the signs to the printed text, children as young as 3 years old can learn to read.
❖ Fingerspelling (Manual Alphabet) and Sign Language Fluency. Children’s ability to understand fingerspelled words and American Sign Language (ASL) is a predictor of their ability to write letters of the alphabet and acquire other skills necessary for emergent literacy. These skills help them acquire later reading comprehension skills as well as abilities in math and other school subjects.
Guidelines for Reading Aloud with DHH Children
All children benefit from sharing books with an adult. Deaf children, however, will need more experiences and exposure to the written text, which is different from their primary sign language. Suggestions for making the shared reading experience enjoyable include these tips adapted from 15 Principles for Reading to Deaf Children (Schleper, 1997):
Here are some specific strategies on how to connect the signs to the written text (Berke, 2013):
Remember: Whether or not the adult is fluent in sign language, everyone should grab the opportunity to read books with a child as often as possible. This will become a meaningful activity that the adult and child do together, and it can create lifelong memories!
