Who Am I?
Principal Investigator: Dr. Leala Holcomb
As a deaf researcher specializing in language and literacy within deaf education, I have observed a major limitation in the field: a lack of evidence-based instructional methods for signed language during the formative early school years, when language development is most critical.
My 3-year research project aims to address this gap by working with teachers and students from PreKindergarten through 3rd grade.
Below, you will find an overview of the theoretical frameworks guiding the evidence-based instructional methods that are applied to ASL literacy instruction for deaf students, along with information on four experimental studies currently underway.
