Abstract
This article describes a continuing programme of school-based applied research. The basis of this research, which originated in a project called ‘Thinking Together’, lies in the relationship between language and cognitive development postulated by sociocultural theory. The research has developed and tested methods for improving the quality of classroom interaction amongst teachers and students, looking for improved levels of collaboration, reasoning, and academic attainment as the desirable outcomes. A key strand of this research concerns the use of digital technology for supporting classroom dialogue and students’ emerging thinking over time. As we will explain, the outcomes of several research projects pursuing this line of enquiry have yielded positive results which have direct implications for classroom pedagogy and practice.
