High Ability, Hidden Gaps: Building Quantitative Reasoning amongst Singapore’s Mathematically Literate
No full textIn Singapore, where primary and secondary students routinely top standardized worldwide mathematics examinations, a paradox emerges: when reaching university, many struggle to apply their skills critically in real-world contexts. This commentary examines the challenges and strategies involved in teaching quantitative reasoning (QR) to mathematically literate students in a top-ranking Singaporean university. While these students arrive well-trained in computation and procedural problem-solving, they often lack confidence and flexibility in ambiguous, data-driven decision-making. This article argues that fostering QR education is crucial not only for Singapore but for education globally, as QR skills underpin evidence-based reasoning within and across disciplines. Such an approach would involve embracing the novelty of QR, cultivating confidence through inquiry-based learning, building skills through authentic problem-solving, and fostering a collaborative environment where communication – perhaps over and above computation – is a core competency

No full textThe N Framework: A Teacher Knowledge Framework for Numeracy across the Curriculum
No full textGovernments and policymakers around the world are encouraging teachers to teach numeracy across the curriculum. This paper proposes a theoretical framework for the knowledge required to teach numeracy across multiple disciplines. The concept of teacher knowledge is complex and consists of many different facets of knowledge. This paper proposes a framework that integrates theories from existing models of general and subject specific teacher knowledge, along with a model of numeracy. The authors developed the N framework, an integrated framework of numeracy knowledge, subject specific knowledge, and pedagogical content knowledge. Each element is essential for teaching numeracy across the curriculum in the 21st century. The “N” framework is designed to support teacher educators in designing and delivering courses in Initial Teacher Education and professional development programmes that prepare teachers to embed numeracy meaningfully in their subject disciplines. It also provides a valuable tool for guiding curriculum planning, numeracy learning opportunities, and reflective practice within teacher education contexts
Notes on the Birds of Schirmacher Oasis, Dronning Maud Land, East Antarctica.
No full textThe Schirmacher Oasis in central Dronning Maud Land, East Antarctica, has a long history of ornithological observations and is one of the few areas in East Antarctica experiencing a warming climate. Snow Petrels Pagodroma nivea and Wilson’s Storm Petrels Oceanites oceanicus were reported to breed at Schirmacher Oasis in the past, but currently the only confirmed regular breeding species is the South Polar Skua Stercorarius maccormicki. This note summarises observations at the Oasis in November and December 2023. Wilson’s Storm Petrels were the most abundant bird, breeding at several sites along the northern scarp in December. Pairs of Adelie Penguins Pygoscelis adeliae were seen at two sites, but no breeding was observed. A pair of Southern Fulmars Fulmarus glacialoides displaying on a cliff in December represent the first record of this species for the Oasis. Snow Petrels were only recorded in November, commuting through the area, presumably to breeding sites farther inland. Three pairs of South Polar Skuas were recorded incubating in mid-December, with the first chick hatching on 18 December. Numbers of skua pairs have decreased steadily from 10 pairs in the 1980s and 1990s, presumably due to removal of food subsidies from station scraps
Variation in the Heartbeat of the White Tern \u3ci\u3eGygis alba\u3c/i\u3e during Incubation
No full textRapid global heating is a particular danger to tropical birds already near their thermal maximum. White Terns Gygis alba are important to tourism in the Seychelles Islands, where, in 1974, we took an unexpected opportunity to measure the heart rate of two incubating adults. We found that the birds had higher heart rates at night compared to during the day, and their heart rates increased rapidly when approached by people. Local temperatures have risen considerably since these data were collected nearly 50 years ago and are predicted to rise even further by 2100. Given the importance of White Terns as a resource for ecotourism, and the likelihood that they will move closer to their thermal maxima as climates warm, an urgent re-evaluation of their thermoregulatory responses to approach by people is warranted
