School inspections in low- and middle-income countries: Explaining impact and mechanisms of impact

Many efforts to implement and improve school inspections have been modelled on examples from high-income countries, and many studies on the effectiveness of such systems have also only been carried out in these countries. However, local contexts in low- and middle-income countries are very different from those in developed countries, and findings about the effectiveness of school inspections from Western studies are therefore not easily transferable to low- and middle-income countries. Existing literature portrays complex and varied links amongst governance context, policy, design of accountability systems, mechanisms of impact and school outcomes that make translation of conditions across studies challenging. This paper presents the results of a systematic review about the conditions under which school inspections lead to improvement in schools and to positive learning outcomes for schoolchildren in low- and middle-income countries, especially the poorest and most marginalised.     

The effects of sodium bicarbonate ingestion on cycling performance and acid base balance recovery in acute normobaric hypoxia

This study investigated the effects of two separate doses of sodium bicarbonate (NaHCO₃) on 4 km time trial (TT) cycling performance and post-exercise acid base balance recovery in hypoxia. Fourteen club-level cyclists completed four cycling TT’s, followed by a 40 min passive recovery in normobaric hypoxic conditions (FiO₂ = 14.5%) following one of either: two doses of NaHCO₃ (0.2 g.kg^?1 BM; SBC2, or 0.3 g.kg^?1 BM; SBC3), a taste-matched placebo (0.07 g.kg^?1 BM sodium chloride; PLA), or a control trial in a double-blind, randomized, repeated-measures and crossover design study. Compared to PLA, TT performance was improved following SBC2 (p = 0.04, g = 0.16, very likely beneficial), but was improved to a greater extent following SBC3 (p = 0.01, g = 0.24, very likely beneficial). Furthermore, a likely benefit of ingesting SBC3 over SBC2 was observed (p = 0.13, g = 0.10), although there was a large inter-individual variation. Both SBC treatments achieved full recovery within 40 min, which was not observed in either PLA or CON following the TT. In conclusion, NaHCO₃ improves 4 km TT performance and acid base balance recovery in acute moderate hypoxic conditions, however the optimal dose warrants an individual approach.     

New Visuality in Art/Science: A Pedagogy of Connection for Cognitive Growth and Creativity

New visuality in art/science pedagogies challenges teachers to rethink their curriculum and the role of digital new media in facilitating conceptual thinking and the role of the creative representation of knowledge. Recent neuroscientific research on cognition, perception, memory, and emotion inform and provoke implications for 21st-century learning. Analysis of student artwork uncovers pedagogical challenges for teachers. Teachers use visual learning and its forms of higher process thinking to allow students to make cognitive connections with images, giving them the capacity to integrate concepts for the communication of art/science learning. Examples of student learning from years 3–5 and 15–17 illustrate these ideas.     

Match-Fixing: Working Towards an Ethical Framework

How does match-fixing, or other unfair manipulation of matches, that involves under-performance by players, or refereeing and umpiring that prevents fair competition, be thought of in ethical terms? In this article, I outline the different forms that match-fixing can take and seek to comprehend these disparate scenarios within Kantian, Hegelian and contractualist ethical frameworks. I tentatively suggest that, by developing an ethical opposition to match-fixing in sport, we can give much greater substance to popular phrases such as ‘respect for the game’, encompassing the value of sport itself and respect for other players, fans, sponsors and organisers. Arguing that match-fixing denies recognition to these ‘others’ demonstrates how fundamentally match-fixing ‘hollows out’ sport because a fixed match is of no worth: the whole value of the game has literally been evacuated.
