Professor Warrican has produced a body of scholarship in literacy in the Caribbean context; an environment in which issues such as influences of a colonial past; democracy in education; small state characteristics; diversity in classrooms; multilingualism; and multiculturalism must be taken into account in literacy education.
He advocates for change in literacy education, and in education in general and promotes the benefits of action research in the classroom and transformative education. He has a keen interest in comparative education, especially when linked to language and culture. Professor Warrican has served on the CARICOM Task Force for Teaching and Teacher Education.
