Education and development: Thirty years of continuity and change

At the end of the 30th volume of IJED and in the year that the journal published its 1000th paper, it is appropriate to look back at the journal's development. In doing so, this article will discuss a series of important issues regarding the future of the field of international education and development and how it engages with development studies. The paper concludes that the challenge for IJED and for the wider work of its readership is to start imagining a more radical future in which we seek more purposefully to build bridges with other disciplines, engage with new methodological tools and encourage fresh voices but above all else communicate more clearly what we do and do not know about the wonderful complexity of the education–development relationship.     

‘The fun we had and the way we went about it’: Is now the time to learn lessons from L.A.T.E.’s past?

In the United Kingdom there appears to be a move to reduce the influence of ‘top down’ or centrally driven teaching and learning reforms in favour of returning control to schools and teachers to make necessary improvements at a local level. In this context, ideas about ‘professional learning communities’ or ‘communities of practice’ are potentially fruitful. This article, drawing on the author’s own research, suggests that if we are to take subject English into a life beyond the National Strategies, it would be worth our remembering how one English ‘community of practice’– the London Association for the Teaching of English – helped to shape one model of the discipline.     

Comparison of a finite element model of a tennis racket to experimental data

Modern tennis rackets are manufactured from composite materials with high stiffness-to-weight ratios. In this paper, a finite element (FE) model was constructed to simulate an impact of a tennis ball on a freely suspended racket. The FE model was in good agreement with experimental data collected in a laboratory. The model showed racket stiffness to have no influence on the rebound characteristics of the ball, when simulating oblique spinning impacts at the geometric stringbed centre. The rebound velocity and topspin of the ball increased with the resultant impact velocity. It is likely that the maximum speed at which a player can swing a racket will increase as the moment of inertia (swingweight) decreases. Therefore, a player has the capacity to hit the ball faster, and with more topspin, when using a racket with a low swingweight.     

Touching practice and physical education: deconstruction of a contemporary moral panic

This paper explores the insecurities and discursive moral panics elicited by the discussion of intergenerational touch in education, and their subsequent manifestation in ‘classroom panopticism’. In a number of contexts, public hysteria has grown around the interaction between adult and child, and whether this interaction stays within the narrow parameters of a generally consensual ‘acceptability’. Crossing these boundaries carries grave consequences for those deemed to be exploiting their position and this has had significant implications for the self-identity of practitioners. This climate of preventative fear has also served to manipulate regulatory method, realigning conceptions of practitioner independence. Drawing on interviews with Physical Education teachers in English secondary schools, and applying a Foucauldian theoretical framework, with particular reference to his interpretation of panopticism, this paper investigates the conceptual transformation of contemporary education. Whilst school spaces were once representative of stability, in which roles were clearly defined, the hierarchical dynamic has changed. The teacher, who previously presided with relative professional freedom and autonomy, is now subject to myriad pressures associated with ‘appropriate’ behaviour and the avoidance of any ‘problematic’ interactional incident. Foucault's treatment of panopticism is apt here, as teachers must conduct themselves with an acceptance that they are now governed by an unpredictable yet persistent practical scrutiny.     

Associations of Number Line Estimation With Mathematical Competence: A Meta‐analysis

The number line estimation task is widely used to investigate mathematical learning and development. The present meta‐analysis statistically synthesized the extensive evidence on the correlation between number line estimation and broader mathematical competence. Averaged over 263 effect sizes with 10,576 participants with sample mean ages from 4 to 14 years, this correlation was r = .443. The correlation increased with age, mainly because it was higher for fractions than for whole numbers. The correlation remained stable across a wide range of task variants and mathematical competence measures (i.e., counting, arithmetic, school achievement). These findings demonstrate that the task is a robust tool for diagnosing and predicting broader mathematical competence and should be further investigated in developmental and experimental training studies.     

“We power democracy”: Exploring the promises of the political data analytics industry

Data-driven campaigning has been in the spotlight over several years. Yet, we still have a limited understanding of political data analytics companies: how they envision data analytics and voter targeting, their role in electoral processes and what promises they make to their clients. This article focuses on the way in which such issues are conceived of in the marketing rhetoric of the political data analytics industry. Drawing on a sample of 19 political data analytics companies it systematically explores the ways in which data analytics is envisioned and marketed as a powerful tool in electoral processes, exposing a fundamental disconnect between scholarly discourse on the one hand – often critical of the claims of these companies about the efficacy of their methods – and a highly functionary data imaginary on the other hand, actively fostered by the political data-analytics industry and the media.     

The entanglement of trust and knowledge on the Web

In this paper I use philosophical accounts on the relationship between trust and knowledge in science to apprehend this relationship on the Web. I argue that trust and knowledge are fundamentally entangled in our epistemic practices. Yet despite this fundamental entanglement, we do not trust blindly. Instead we make use of knowledge to rationally place or withdraw trust. We use knowledge about the sources of epistemic content as well as general background knowledge to assess epistemic claims. Hence, although we may have a default to trust, we remain and should remain epistemically vigilant; we look out and need to look out for signs of insincerity and dishonesty in our attempts to know. A fundamental requirement for such vigilance is transparency: in order to critically assess epistemic agents, content and processes, we need to be able to access and address them. On the Web, this request for transparency becomes particularly pressing if (a) trust is placed in unknown human epistemic agents and (b) if it is placed in non-human agents, such as algorithms. I give examples of the entanglement between knowledge and trust on the Web and draw conclusions about the forms of transparency needed in such systems to support epistemically vigilant behaviour, which empowers users to become responsible and accountable knowers.
