In this volume, Rob and David trace the monumental shifts in theory, research, and practice related to reading education and literacy, with particular attention to what they consider the central goal of literacy—making meaning. Each section describes a specific epoch, including a brief snapshot of how the reader of that period is envisioned and characterized by researchers and teachers, as well as a deep discussion of the ideas and contextual events of that era. These developmental waves are organized in rough historical sequence by a series of shifts in underlying theoretical and scholarly lenses—from the behavioral to the psycholinguistic to the cognitive to the sociocultural to the critical to the multimodal to the global.
