Peer Instruction (PI) is an evidence based pedagogy commonly used in undergraduate physics instruction. When asked questions designed to test conceptual understanding, it has been observed that the proportion of students choosing the correct answer increases following peer discussion; however, relatively little is known about what takes place during these discussions or how they are beneficial to the processes of learning physics [M. C. James and S. Willoughby, Am. J. Phys. 79, 123 (2011)]. In this paper a framework for analyzing PI discussions developed through the lens of the "resources model" [D. Hammer, Am. J. Phys. 64, 1316; D. Hammer et al., Information Age Publishing (2005)] is proposed. A central hypothesis for this framework is that the dialogue with peers plays a crucial role in activating appropriate cognitive resources, enabling the students to see the problem differently, and therefore to answer the questions correctly. This framework is used to gain greater insights into the PI discussions of first year undergraduate physics students at the University of Edinburgh, UK, which were recorded using Livescribe Smartpens. Analysis of the dialogues revealed three different types of resource activation corresponding to increasing cognitive grain size. These were activation of knowledge elements, activation of linkages between knowledge elements, and activation of control structures (epistemic games and epistemological frames). Three case studies are examined to illustrate the role that peer dialogue plays in the activation of these cognitive resources in a PI session. The implications for pedagogical practice are discussed.

This paper explores the social dimensions of online learning - the ways in which learners interact and communicate with other learners and their tutors using electronic communication networks. The context for this exploration is a module provided by a networked, and geographically dispersed, higher education institution. An evaluation of the module draws on the experiences of students and tutors participating in their first online course. Based on these experiences and the research literature, the paper discusses the extent to which face-to-face models of communication should be recreated in online contexts and the extent to which tutors should structure online interaction patterns and modes of discourse. Also examined is the way in which online learning leads to new 'hybrid' and 'converging' styles of communication and to the intermixing of academic and personal discourses. Overall, it is argued that the social context of online learning is qualitatively different from face-to-face learning and that this has significant implications for online learning design

In examining the work of the prefix 'post', we aim to contribute to the current postdigital dialogue. Our paper does not provide a rationale for the use of 'postdigital' in the title of this journal: that has been thoroughly explored elsewhere. We want instead to consider the work the prefix might do. We look at 'post', as it appears to 'act' in the terms of 'postmodernism' and 'posthumanism', suggesting that modernism and humanism are in need of questioning and reworking. We also examine what gets 'post-ed', or sometimes 'com-posted'. (Com-is another interesting prefix, meaning 'with'.) We then consider how these inquiries inform our understanding of a 'postdigital reality' that humans now inhabit. We understand this as a space of learning, struggle, and hope, where 'old' and 'new' media are now 'cohabiting artefacts' that enmesh with the economy, politics and culture. In entering this postdigital age, there really is no turning back from a convergence of the traditional and the digital. However, this is not simply a debate about technological and non-technological media. The postdigital throws up new challenges and possibilities across all aspects of social life. We believe this opens up new avenues too, for considering ways that discourse (language-in-use) shapes how we experience the postdigital.

This article is a multi-authored response to an editorial ‵Postdigital Science and Educa-tion′ published in 2018 by Petar Jandrić, Jeremy Knox, Tina Besley, Thomas Ryberg, Juha Suoranta and Sarah Hayes in Educational Philosophy and Theory as a mission statement for the journal Postdigital Science and Education. Nineteen authors were invited to produce their sections, followed by two author-reviewers who examined the article as a whole. Authors' responses signal the sense of urgency for developing the concept of the postdigital and caution about attempts at simplifying complex relationships between human beings and technology. Whilst the digital indeed seems to become invisible, we simultaneously need to beware of its apparent absence and to avoid overemphasizing its effects. In this attempt, authors offer a wide range of signposts for future research such as 'the critical postdigital' and 'postdigital reflexivity'; they also warn about the group's own shortcomings such as the lack of 'real' sense of collectivity. They emphasize that postdigital education must remain a common good, discuss its various negative aspects such as smartphone addiction and nomophobia, and exhibit some positive examples of postdigital educational praxis. They discuss various aspects of postdigital identities and point towards the need for a postdigital identity theory. With these varied and nuanced responses, the article opens a wide spectrum of opportunity for the development of postdigital approaches to science and education for the future.

In this paper we develop knowledge of the discourse that takes place between teacher and students in two large undergraduate classes which use a flipped, active learning approach. In flipped classes students encounter the content through pre-class resources, freeing up class time for more active engagement with the material. This results in increased opportunities for teacher-student interactions which may be beneficial for learning. Our aim here is to explore the nature and purposes of these dialogues. Two case studies from introductory physics classes at the University of Edinburgh are analysed through a sociocultural perspective. Three main purposes of dialogues are observed: 1) Involving students in sense-making, 2) Guided expert modelling and 3) Wonderment questions. We found that the dialogues predominantly use a triadic Initiation, Response, Feedback (IRF) format and are authoritative in nature, but work together to create an interactive learning environment that can be described as 'ideologically dialogic'
