The study considered whether adding sign language graphics to the books being used for reading instruction in a first-grade classroom would promote the literacy development of students who are deaf or hard of hearing. The researchers also sought to discover whether materials existed to put the process of modifying leveled texts within the reach of the typical classroom teacher, in terms of cost and procedure. Students' reading behaviors seemed to indicate that the presence of sign graphics supported their development as readers. The materials needed to create sign support for the English print in the leveled books were commercially available. (Contains 1 figure and 1 table.)
