The Bright Triad And Five Propositions: Toward A Vygotskian Framework For Deaf Pedagogy And Research, Michael E. Skyer

Articles

L.S. Vygotsky’s contributions to social research shifted paradigms by constructing now-foundational theories of teaching, learning, language, and their interactions in education. This manuscript contextualizes and elucidates a nearly-forgotten, century-old component of Vygotskian deaf education research. The Fundamentals of Defectology compiles decades of Vygotsky’s experimental, methodological, and theoretical research about deafness, the psychology of disability, and special methods of pedagogy. Drawing on Defectology, two arguments are developed using the method of dialectics; they first synthesize Vygotsky’s deaf research corpus, then juxtapose it against contemporary theories and evidence. The first argument describes three principles that exemplify Vygotsky’s optimistic framework for deaf pedagogy: …
