A method of providing accurate velocity feedback of performance on an instrumented kayak ergometer

On a kayak ergometer, an accurate simulation of the athlete-paddle-kayak system kinematics is essential for analysing the relationship between technique and performance. The purpose of this study was to establish a strong relationship between performances on flatwater and performances on an ergometer by means of propulsive force measurement and drag models. Two trials were performed by 12 kayakers in which they were first timed over 250 m of flatwater kayaking (the reference test) and were then asked to perform a trial of the same duration on the ergometer with the same perceived physical exertion. Three techniques for measuring propulsive force and three drag models generated nine combinations, which were all evaluated for their ability to estimate kayak velocity. For each combination, the distance covered by the athlete on the ergometer was simulated. A kayakers’ ergometer ranking was based on the average velocity in the ergometer trial. Both distance and ranking were compared to the on-water results. The simulation with the best combination of force measurement and drag model gave an accurate estimate of distance (253 ± 10.5 vs. 250 m) and ranking compared to the reference test.     

Roots and Rhizomes—Some Reflections on Contemporary Pedagogy

During this article, I look at three images of thought which feature in Deleuze and Guattari's A Thousand Plateaus and consider their relevance to contemporary pedagogy. Deleuze and Guattari begin by discussing tree‐like thought, which involves an insular depiction of the world. I suggest that the performative apparatus, which structures contemporary pedagogy in the comprehensive school, is also tree‐like. Deleuze and Guattari's second image of thought is the fascicular root. Here the principle root is aborted leading to a multiplicity, which flows from it. With fascicular thought, the unity, which is aborted in the object, is returned to in the subject who gains control of multiplicities. In this section I provide a reading of a Classics lesson portrayed in The Secret History by Donna Tartt and go on to focus on Ronald Barnett's contribution to a debate with Paul Standish, which features in The Blackwell Guide to the Philosophy of Education. In the third section of the article, I consider Deleuze and Guattari's third image of thought—the rhizome. Rhizomes grow by a process of cloning or lateral spreading; they do not have the central trunk of the tree, with roots and branches extending outwards from this. At the end of this section, I look at two Classics lessons that represent tree‐like and rhizomatic pedagogies in turn. I attempt to enrich this discussion by providing a reading of a scene from The History Boys.     

'England Expects Every Man to do his Duty': The gendering of the citizenship textbook 1940-1966

This article is based on a pilot study investigating the representation of women in a sample of texts for citizenship education in the immediate post-Second World War era in England. The authors argue that existing research into the field of education for citizenship does not engage adequately with how the subject is taught in schools, and how citizenship education constructs the polity in line with normative and traditionalist assumptions about the role of women and men in society. By studying the texts of citizenship for the period 1940-66, the authors argue that researchers can, if they deploy a more critically engaged approach to the way in which notions of 'citizenship' and 'polity' are gendered, generate new questions and new understandings of how education for citizenship functions in schools.     

Two tales of a city: John Walson,Sr., Mahanoy city,and the “founding”; of cable TV

For the last 20 years, scholarly and popular accounts of the development of cable television have recounted the story of John Walson, Sr., who claimed to have started the first CATV system in June of 1948 in Mahanoy City, Pennsylvania. When Walson died in March of 1993, newspapers around the country credited him with starting the nation's first cable system and even “founding”; the industry. The claim, however, has always been clouded by questions and a lack of documentation. This paper reports the results of an investigation of the Walson story. It concludes that, as bright and promising as the Walson tale may be, it probably is not true. At the very least, the preponderance of evidence suggests that Walson got his start in the community antenna television business in late 1950, about the same time as many others around the country and, importantly, probably after another group of businessmen already had begun a system in Mahanoy City itself.     

NOTES ON ONGOING RESEARCH IN SPECIAL EDUCATION

ABSTRACT

With the support of Unicef and Unesco, the Romanian Ministry of Education has since 1993 been operating a programme to promote the educational and social integration of children and young people with special needs. In a comparatively short time the programme has grown from a pair of pilot projects to comprise a number of interactive elements which include a Joint European Project within the EU's TEMPUS programme, as well as provision for networking, and for describing, monitoring and generalizing experience of good practice. In this process a ‘philosophy’ of integration has developed which is appropriate to Romanian realities and which offers the possibility of an integration project to everyone concerned with special needs. The paper stresses the importance of the voluntary organizations and their new cooperative relationship with the institutions, and of the role of the universities in professional training. The paper ends with a discussion of the barriers and supports to integration, together with some conclusions about the significance and future of the programme.     

Development and Use of a Conceptual Survey in Introductory Quantum Physics

Conceptual surveys have become increasingly popular at many levels to probe various aspects of science education research such as measuring student understanding of basic concepts and assessing the effectiveness of pedagogical material. The aim of this study was to construct a valid and reliable multiple‐choice conceptual survey to investigate students’ understanding of introductory quantum physics concepts. We examined course syllabi to establish content coverage, consulted with experts to extract fundamental content areas, and trialled open‐ended questions to determine how the selected content areas align with students’ difficulties. The questions were generated and trialled with different groups of students. Each version of the survey was critiqued by a group of discipline and teaching experts to establish its validity. The survey was administered to 312 students at the University of Sydney. Using the data from this sample, we performed five statistical tests (item difficulty index, item discrimination index, item point biserial coefficient, KR‐21 reliability test, and Ferguson’s delta) to evaluate the test’s reliability and discriminatory power. The result indicates that our survey is a reliable test. This study also provided data from which preliminary findings were drawn on students’ understandings of introductory quantum physics concepts. The main point is that questions which require an understanding of the standard interpretations of quantum physics are more challenging for students than those grouped as non‐interpretative. The division of conceptual questions into interpretive and non‐interpretive needs further exploration.
