Sorry jillio, but I think you should have added this information in your previous post in order to place it in the correct context. The way it has been presented in the post is slightly misleading.
With that being said, I would like to add this from the paper that jillio previously quoted:
Thanks
With that being said, I would like to add this from the paper that jillio previously quoted:
In addition to accounts of increased training efforts, much dialogue on the methodology has been presented in the literature. Few writers, however, are substantiating or refuting claims with rigorous quantitative research. In the past decade the profession's three national journals, the American Annals of the Deafi the Journal of Deaf Studies and Deaf Education, and Sign Language Studies, have published only one article (i.e., Andrews, Ferguson, Roberts, & Hodges, 1997) providing any empirical data specifically on the issue of dual language methodology. Related journals and university dissertations have not provided much literature, either. (A list of studies and their results is provided in Table 1). While these studies may indicate promise for the methodology, sample sizes are small and cannot be generalized back to the total population served in the United States. Clearly additional investigation is needed.
Another limitation of these studies is that most of them targeted residential programs for the deaf. Adopting a sociolinguistic view, researchers prefer this setting over others for its availability of linguistic and cultural resources, believed to be instrumental components in addressing academic needs of bilingual deaf and hard of hearing children. While this perspective is valid and does enable researchers to understand certain phenomena more fully, more than 70% of the nation's deaf and hard of hearing children are not served in the residential setting (GRI, 2005; Johnson & Cohen, 1994; Schildroth & Hotto, 1996). Implementation in other settings (e.g., public and charter schools) must also be examined.
Quantitative investigation regarding the impact of ASL/English bilingual education in public schools is virtually nonexistent in the literature.
