Roots and Rhizomes—Some Reflections on Contemporary Pedagogy     

Ian Munday 《Journal of Philosophy of Education》2012,46(1):42-59

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.  相似文献

Development and Use of a Conceptual Survey in Introductory Quantum Physics     

Sura Wuttiprom  Ian D. Johnston  Ratchapak Chitaree  Chernchok Soankwan 《International Journal of Science Education》2013,35(5):631-654

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.  相似文献   

Adult education,lifelong learning and citizenship: some ifs and buts     

Ian Martin 《International Journal of Lifelong Education》2013,32(6):566-579

This paper suggests that the dominant discourse of lifelong learning is a political rather than an educational discourse. On this view, lifelong learning enables the deconstruction of welfare to be effected through the reconstruction of citizenship. Democratic citizenship properly understood, on the other hand, depends on determined progress towards a more equitable distribution of material and cultural resources among citizens. Education on its own can do little to ensure that such structural change takes place. It is, nevertheless, the task of critical adult education, as distinct from economistic models of lifelong learning, to raise such questions as urgent issues for democratic deliberation and debate, and to expand our notions of what it means to be active citizens in a democratic society. The paper contains the text of a talk given at the annual study conference of the UK's National Institute of Adult Continuing Education in April 2002.  相似文献

In their very own words: authors and scholarly journal publishing     

David Nicholas  Hamid R. Jamali M.  Paul Huntington  Ian Rowlands 《Learned Publishing》2005,18(3):212-220

This paper presents the results of a major investigation by questionnaire of author attitudes towards scholarly publishing, which was funded by the Publisher's Association. Altogether, the views of nearly 4,000 authors were obtained and this paper concerns just those thousand or so authors who accepted the invitation to write freely about their own personal feelings and experiences. Using QSR N6 textual analysis software, their comments were processed and themes extracted. While the rest of the questionnaire, which was formed of closed‐question, tick‐box type questions, clearly must have had some impact on their thinking, the authors had considerable latitude in regard to what they could say. The paper provides a unique opportunity to hear their views directly. The pressing topics turned out to be (in rough order of concern): the peer‐review system, copyright, journal prices, alternative business models for journal publishing, big deals, Elsevier, electronic publishing and digital journals.  相似文献

Physiological and metabolic responses of wheelchair athletes in different racing classes to prolonged exercise     

Campbell IG  Williams C  Lakomy HK 《Journal of sports sciences》2004,22(5):449-456

The aims of this study were to examine and compare selected physiological and metabolic responses of wheelchair athletes in two paraplegic racing classes [T3: n = 8 (lesion levels T1-T7; paraplegics); T4: n = 9 (lesion levels below T7; paraplegics)] to prolonged exercise. In addition, we describe the responses of three tetraplegic athletes [T2: n = 3 (lesion levels C6/C7: tetraplegics)]. Twenty athletes completed 90 min of exercise at 75% VO2peak on a motorized treadmill adapted for wheelchairs. The mean (+/- s) heart rates of the T3 and T4 racing classes were 165 +/- 2 and 172 +/- 6 beats.min-1, respectively. For the T4 racing class, heart rate gradually increased during the test (P < 0.05), whereas for the T3 racing class, heart rate reached a plateau after an initial increase. The mean heart rate of the tetraplegics was 114 +/- 3 beats.min-1. The T3 and T4 classes exhibited similar respiratory exchange ratios, plasma lactate and glucose concentrations throughout the test. For both the T3 and T4 racing class, free fatty acid, glycerol, ammonia, urea and potassium concentrations had increased from resting values by the end of the test (P < 0.05). In conclusion, the results of this study suggest that endurance-trained wheelchair athletes are able to maintain velocities equivalent to the same relative exercise intensity (75% VO2peak) for prolonged periods irrespective of lesion level.  相似文献   

Which starting style is faster in sprint running--standing or crouch start?     

Salo A  Bezodis I 《Sports biomechanics / International Society of Biomechanics in Sports》2004,3(1):43-53

The purpose of this study was to further understand the biomechanical differences between the standing and crouch starting methods, and to investigate whether one of the starting styles provides better acceleration and proves to be faster. Six university track team sprinters performed 2 x 3 x 50 m trials. Digitised video, photocell timing, and velocity data revealed that during the first steps of the performance the standing start produced higher body centre of mass horizontal velocity than the crouch start. This may be due to the longer distance between the feet in the standing start, which caused longer push-off phases, and the work against gravity in the crouch start. However, this advantage in horizontal velocity disappeared by the 10 m mark, where similar velocities were recorded with both start styles. Further, there was no statistically significant difference between the two starting styles in horizontal velocity at the 25 m mark, nor in the time to reach the 25 m or 50 m mark. Regarding relay running, where athletes need to decide to adopt either a crouch start without starting blocks or a standing start, there seems to be no specific reason for outgoing athletes to use a crouch start, although this area warrants further investigation.  相似文献
