'Multimodal Teaching and Learning: The Rhetorics of the Science Classroom achieves the rare goal of explicating multimodality as both theory and practice. This is an importantly concrete analysis, derived from extended, careful, and interdisciplinary observation, which challenges our thinking about how meaning and knowledge are shaped by our modes of communication. The book appeals to a wide range of scholars and practitioners far beyond the science classroom.'Professor Ron Scollon, Department of Linguistics, Georgetown University.
