An increasingly popular approach to second and foreign language education, this book focuses on incidental learning: how students learn words from reading. Despite its popularity, some researchers have questioned this theory that students can learn new words by inferring meanings based on a text they are reading. So, why does the incidental method not work for some students? What are the conditions for naturalistic learning to occur? What do students need to be able to do while reading in order to learn words successfully? Tackling these questions head-on, this book provides researchers and educators with a more specific account of the processes behind the seemingly naturalistic method. Clarifying the connection between reading and word learning processes, Megumi Hamada proposes a new model, the Cognitive Model of Word-Meaning Inference, to describe how we obtain and use word-form and contextual information for learning words and the pedagogical applications of this. A significant new contribution to research in the field, Learning Words from Reading provides a cognitive perspective on how students learn new words from reading in a second or foreign language.
