This edited collection of articles illustrates more recent work on beliefs about SLA, drawing on the thinking of (educational) philosophers and (discursive) psychologists, including Dewey, Bakhtin, Vygotsky, and Potter. The data for these reports have been collected by a variety of means, e.g., narratives, diary/journal entries, interviews, completion tasks, classroom observations, and subjected to a number of novel ways of analysis. The book puts past and present research into perspective by comparing and contrasting different approaches. Both beliefs from second/foreign language learners and teachers are subject of research. The contributions provide detailed accounts of starting points, definitions, methods of data collection and analysis, main findings and implications for further research.
