Dr. Gordon Wells is currently Professor of Education at the University of California, Santa Cruz, where he researches and teaches in the fields of: language, literacy, and learning; the analysis of classroom interaction; and sociocultural theory. As an educator, his particular interest is in fostering dialogic inquiry as an approach to learning and teaching at all levels, based on the work of Vygotsky and other sociocultural theorists. The rationale for this approach together with examples of it in practice are presented in Dialogic inquiry: Towards a Sociocultural Practice and Theory of Education (Cambridge University Press, 1999). From 1969 to 1984, he was the Director of the Bristol Study of Language Development at Home and at School, and from 1984 to 2000, he was a professor at the Ontario Institute for Studies in Education of the University of Toronto, where he was involved in several collaborative action research projects with educational practitioners in Canada. Chief among these was a project entitled a Developing Inquiring Communities in Educationa (DICEP), which was funded by the Spencer Foundation. Books arising from this work are Constructing Knowledge Together (Heinemann, 1992), Changing Schools from Within (OISE Press and Heinemann, 1994), and Action, Talk and Text: Learning and Teaching through Inquiry, written with his DICEP teacher colleagues, (Teachers College Press, 2001). He is also co-editor of Learning for Life in the 21st Century: Sociocultural Perspectives on the Future of Education (Blackwell, 2002).
