This article reviews published research on spelling interventions designed for students with learning disabilities (LD) who are poor spellers. Thirty-eight spelling studies, including singlesubject and group designs, were located. Study interventions consisted of four types: instructional techniques, computer-assisted instruction, study strategies, and multisensory/modality training. These studies are discussed here with regard to subjects, methods, and findings. Conclusions and implications for spelling instruction and for future research are presented.Students with learning disabilities (LD) have lower achievement levels than their low-achieving nondisabled peers across all subject areas, but spelling ability is the most powerful discriminator between students with LD and other low achievers (Deshler, Schumaker, Alley, Warner, & Clark, 1982). Although spelling deficits are frequently identified during elementary school years, these deficits increase as students reach secondary education levels (Poplin, Gray, Larsen, Banikowski, 8c Mehring, 1980). One study documented a third-grade mean spelling score among seventh-grade adolescents with LD (Deshler, Schumaker, Alley, Warner, 8c
Clark, 1982).Spelling is closely related to other subjects, particularly to reading (Beers, 1980). However, controversy exists between researchers who contend that spelling is a natural extension of reading and others (e.g., Chomsky, 1979) who argue that writing, a more concrete task, developmentally occurs first (see Vacca, Vacca, 8cGove, 1987, for a discussion). Nevertheless, agreement exists that spelling is a more difficult task than reading (Frith, 1980;Nelson, 1980); it requires production of an exact sequence of letters, offers no contextual clues, and requires greater numbers of grapheme-to-phoneme decisions.There are several possible reasons for the persistence of severe spelling deficits for students with LD. First, teacher preparation for spelling instruction may be overlooked, due to an overriding emphasis on the instruction of reading and mathematics. Second, minimal instructional time may be allocated to spelling due to beliefs that spelling is of secondary importance in today's extensive curriculum. Third, believing that students acquired these techniques in the primary grades, teachers may neglect instruction in effective spelling strategies.

First, the spelling skill of students with LD is similar developmentally to that of nondisabled students (Gerber, 1986). Second, cognitive strategies, such as those employed for spelling, are generalizable to other academic areas, particularly with training for transfer and teacher prompts (Deshler et al., 1983). Third, in 35 of the 38 spelling interventions presented in this review, explicit spelling instruction resulted in improved spelling performance.Given th...
