The Pedagogy of Primary Historical Sources in Mathematics: Classroom Practice Meets Theoretical Frameworks

We analyze our method of teaching with primary historical sources within the context of theoretical frameworks for the role of history in teaching mathematics developed by Barbin, Fried, Jahnke, Jankvist, and Kjeldsen and Blomhøj, and more generally from the perspective of Sfard’s theory of learning as communication. We present case studies for two of our guided student modules that are built around sequences of primary sources and are intended for learning core curricular material, one on logical implication, the other on the concept of a group. Additionally, we propose some conclusions about the advantages and challenges of using primary sources in teaching mathematics.     

School-based prevention: Effects on obesity and physical performance after 4 years

Abstract

Juvenile obesity is increasing worldwide. Preventive strategies are warranted. The school-based Children's Health Interventional Trial (the CHILT Project) combines health education and physical activity for children. The effect on obesity and physical performance was studied after four years in 12 primary schools compared with five control schools. Anthropometric data were recorded. Physical performance was measured by a coordination test for children (balancing backwards, one-legged obstacle jumping, lateral jumping, sideways movements) and a 6-min run (endurance). No difference in the prevalence and incidence of overweight and obesity was found between the intervention and control schools before and after the intervention. Remission of overweight was higher in the intervention schools (23.2 vs. 19.2%), but not significant. An increase in coordination related to lateral jumping and balancing backwards was apparent in the intervention schools (30.6, s = 10.8 vs. 26.1, s = 10.8, P = 0.005; 21.8, s = 11.8 vs. 19.4, s = 11.7, P = 0.007), and the increase in endurance performance tended to be higher in intervention schools (100.8, s = 122.7 vs. 92.8, s = 126.0, P = 0.055), adjusted for age, sex, baseline test result, and body mass index at final examination. Therefore, preventive intervention in primary school offers the possibility to improve physical performance in children. The prevalence and incidence of obesity were not affected.     

‘The emblem of one united body … one great sporting Maple Leaf’: The Olympic Games and Canada's quest for self-identity

For Canadians, the enduring late nineteenth- and early twentieth-century debate between adherents of sustained British imperialism and those champions of Canadian sovereignty closed in December 1964 by dint of a Canadian Parliamentary act establishing a new national symbol, one that henceforth removed the British ensign from national flag and federal governmental identifications and replaced it with a simple red maple leaf embossed on a white background between two panels of red. This is the primary identification symbol, the logo, indeed the brand, by which Canada is now recognized throughout the world. The birth of the red maple leaf logo's legitimization in both national and international context points to a role played by the Canadian Olympic Committee, the embryo saga of which was superimposed on the initiatives of the nation's first Olympic team, the aggregation of male athletes that competed in the London Games of 1908. This work argues that the introduction of the red maple leaf as a national symbol of Canada, with respect to the logo's initial international debut at the Games of the Fourth Olympiad celebrated in London in 1908, provided the first in a series of succeeding international Olympic occurrences that lent sustenance to a greater Canadian movement towards neoliberal promoted national self-identity and a commensurate beginning of the erosion of what most Canadians would refer to as ‘Britishness’.     

PISA 2015: how big is the ‘mode effect’ and what has been done about it?

The Programme for International Student Assessment (PISA) is an important cross-national study of 15-year-olds’ academic knowledge and skills. Educationalists and public policymakers eagerly await the tri-annual results, with particular interest in whether their country has moved up or slid down the international rankings, as compared to earlier rounds. In 2015 a major change was implemented in PISA, with the introduction of computer-based assessment. This has the potential to reduce comparability of PISA test scores across countries and over time. We investigate this issue using PISA 2015 field trial data for three countries: Germany, Sweden, and Ireland. We show how, if left unaccounted for, the change to computer-based testing could limit the comparability of PISA test scores. We then describe the methodology the study organisers have used to account for such mode effects. Our key conclusion is that although the adjustment made is unlikely to overcome all the potential challenges of switching to computer-based tests, it represents an improvement over the alternative of making no adjustment at all.
