Effects of Morphographic Instruction on the Morphographic Analysis Skills of Deaf and Hard-of-Hearing Students.

Deaf and hard-of-hearing (DHH) students have delayed morphographic knowledge that negatively affects their morphographic analysis and decoding abilities. Morphographic analysis instruction may improve DHH students' morphographic knowledge delay. The purpose of this study was to determine the effects of morphographic instruction on the morphographic analysis skills of reading-delayed, late-elementary DHH students. The research question was: What effect does morphographic instruction have on the morphographic analysis skills of DHH students who are reading below grade level? The study included 3 student participants and 1 teacher participant from a local school district. The researchers used a multiprobe multiple baseline across participants design. The intervention was implemented for 20 min a day, 5 days a week for 2-3 weeks. Visual analysis of the data revealed the requisite number of demonstrations of effect and replications. The intervention improved DHH students' ability to dissect words and determine affix meanings, which may in turn positively affect their decoding abilities. Implications of this study and future research are discussed.
