Sociocultural researchers have claimed that students' learning of science is a discursive process, with scientific concepts and ways of reasoning being learned through engagement in practical enquiry and social interaction as well as individualized activity. It is also often claimed that interacting with partners while carrying out scientific investigations is beneficial to students' learning and the development of their understanding. The research we describe investigated the validity of these claims and explored their educational implications. An experimental teaching programme was designed to enable children in British primary schools to talk and reason together and to apply these skills in their study of science. The results obtained indicate that (a) children can be enabled to use talk more effectively as a tool for reasoning and (b) talk‐based activities can have a useful function in scaffolding the development of reasoning and scientific understanding. The implications of the findings for educational policy and practice are discussed.

Sixty British primary school children aged 9‐10 and their teachers took part in an experimental teaching programme, designed to improve the quality of children's reasoning and collaborative activity by developing their awareness of language use and promoting certain ‘ground rules’ for talking together. Children's subsequent use of language when carrying out collaborative activities in the classroom was observed and analysed, and effects on their performance on Raven's Progressive Matrices test of non‐verbal reasoning were also investigated. Comparative data were gathered from children in matched control classes. Qualitative and quantitative analyses of discourse showed a marked shift in target children's use of language in accord with the aims of the teaching programme, and demonstrated that adherence to the ground rules helped groups solve the reasoning test problems. Children's individual scores on the Raven's test also improved. These findings support a sociocultural view of intellectual development and confirm the value of explicitly teaching children how to use language to reason.

Dialogic: Education for the Internet Age argues that despite rapid advances in communications technology, most teaching still relies on traditional approaches to education, built upon the logic of print, and dependent on the notion that there is a single true representation of reality. In practice, the use of the Internet disrupts this traditional logic of education by offering an experience of knowledge as participatory and multiple. This new logic of education is dialogic and characterises education as learning to learn, think and thrive in the context of working with multiple perspectives and ultimate uncertainty. The book builds upon the simple contrast between observing dialogue from an outside point of view, and participating in a dialogue from the inside, before pinpointing an essential feature of dialogic: the gap or difference between voices in dialogue which is understood as an irreducible source of meaning. Each chapter of the book applies this dialogic thinking to a specific challenge facing education, re-thinking the challenge and revealing a new theory of education. Areas covered in the book include: dialogical learning and cognition dialogical learning and emotional intelligence educational technology, dialogic ‘spaces’ and consciousness global dialogue and global citizenship dialogic theories of science and maths education The challenge identified in Wegerif’s text is the growing need to develop a new understanding of education that holds the potential to transform educational policy and pedagogy in order to meet the realities of the digital age. Dialogic: Education for the Internet Age draws upon the latest research in dialogic theory, creativity and technology, and is essential reading for advanced students and researchers in educational psychology, technology and policy.

This article explores the relationship between ontological assumptions and studies of educational dialogue through a focus on Bakhtin's ‘dialogic’. The term dialogic is frequently appropriated to a modernist framework of assumptions, in particular the neo‐Vygotskian or sociocultural tradition. However, Vygotsky's theory of education is dialectic, not dialogic. From a dialogic perspective the difference between voices in dialogue is constitutive of meaning in such a way that it makes no sense to imagine ‘overcoming’ this difference. By contrast, due to the implicit assumption that meaning is ultimately grounded on identity rather than upon difference, the dialectic perspective applied by Vygotsky interprets differences as ‘contradictions’ that need to be overcome or transcended. A case study of research on exploratory talk is used to illustrate the potential for a fruitful relationship between ‘high level’ theory and research that is relevant to classroom practice.
