Athlete and coach perceptions of technology needs for evaluating running performance     

Paul Fleming  Colin Young  Sharon Dixon  Matt Carré 《Sports Engineering》2010,13(1):1-18

Athletes and their support team utilise technology to measure and evaluate technique and athletic performance. Existing techniques for motion and propulsion measurement and analysis include a combination of indirect methods (high-speed video) and direct methods (force plates and pressure systems). These methods are predominantly limited to controlled laboratory environments (in a small area relative to the competition environment), require expert advice and support, and can take significant time to evaluate the data. Consequently, the more advanced measurement techniques are considered to be restricted to specific coaching sessions, or periods in the year leading up to competition, when the time and expertise of further support staff are available. The more widely used, and simple, devices for monitoring ‘performance’ during running include stopwatches, GPS tracking and accelerometer-based systems to count strides. These provide useful information on running duration, distance and velocity but lack detailed information on many key aspects of running technique. In order to begin the process of development of more innovative technologies for routine use by athletes and coaches, a study was required to improve the understanding of athletes’ and coaches’ perception of their requirements from measurement technology. This study outlines a systematic approach to elicit and evaluate their perceptions, and presents the findings from interviews and a questionnaire. The qualitative data are presented as a hierarchical graphical plot (structured relationship model) showing six general dimensions (technique, footwear and surface, environment, performance, injury and cardiovascular) and shows the development of these general dimensions from the interviewee quotations. The questionnaire quantitative data enhances the study by further ranking characteristics that arise from the interviews. A contrast is shown between short and longer distance runner groups, as might be expected. The current technology available to elite runners is briefly reviewed in relation to the 22 characteristics identified as important to measure. The conclusions highlight the need for newer technologies to measure aspects of running style and performance in a portable and integrated manner, with suggestions as to size and weight likely to be acceptable to users for emerging devices.  相似文献   

Psychometric characteristics of integrated multi-specialty examinations: Ebel ratings and unidimensionality     

Matt Homer  Jonathan Darling  Godfrey Pell 《Assessment & Evaluation in Higher Education》2012,37(7):787-804

Over recent years, UK medical schools have moved to more integrated summative examinations. This paper analyses data from the written assessment of undergraduate medical students to investigate two key psychometric aspects of this type of high-stakes assessment. Firstly, the strength of the relationship between examiner predictions of item performance (as required under the Ebel standard setting method employed) and actual item performance (‘facility’) in the examination is explored. It is found that there is a systematic pattern of difference between these two measures, with examiners tending to underestimate the difficulty of items classified as relatively easy, and overestimating that of items classified harder. The implications of these differences for standard setting are considered. Secondly, the integration of the assessment raises the question as to whether the student total score in the exam can provide a single meaningful measure of student performance across a broad range of medical specialties. Therefore, Rasch measurement theory is employed to evaluate psychometric characteristics of the examination, including its dimensionality. Once adjustment is made for item interdependency, the examination is shown to be unidimensional with fit to the Rasch model implying that a single underlying trait, clinical knowledge, is being measured.  相似文献   

Instructions to Adopt an External Focus Enhance Muscular Endurance     

David C. Marchant  Matt Greig  Jonathan Bullough  Daniel Hitchen 《Research quarterly for exercise and sport》2013,84(3):466-473

Abstract

The influence of internal (movement focus) and external (outcome focus) attentional-focusing instructions on muscular endurance were investigated using three exercise protocols with experienced exercisers. Twenty-three participants completed a maximal repetition, assisted bench-press test on a Smith's machine. An external focus of attention resulted in significant (p < .05) improvements in performance compared to the internal focus of attention, but not the control condition. Seventeen participants completed repetitions to failure at 75% 1-RM on free bench-press and squat exercises. In both tasks, externally focused instructions resulted in significantly greater repetitions to failure than control and internal focus conditions (p < .05). These results support previous research showing beneficial effects of externally focused instructions on movement efficiency.  相似文献

The Scholarship of Teaching and Learning as collaborative working: a case study in shared practice and collective purpose     

Peter Kahn  Peter Goodhew  Matt Murphy  Lorraine Walsh 《高等教育研究与发展》2013,32(6):901-914

The Scholarship of Teaching and Learning (SoTL) has yet to fully enter the mainstream of life in higher education. In this case study, we consider a specific network focused on the reform of engineering education. The network involves global collaboration within the discipline of Engineering and is based around curricular activity that affects entire departments or groups of staff. We suggest that SoTL should pay greater attention to collaboration that addresses substantive disciplinary purposes, further embodying these purposes through spaces, motivations and capacities for action in the disciplinary and departmental setting. We frame our argument around a theoretical model of collaborative working in higher education and go on to offer a synoptic overview of ways to articulate common purpose around teaching and learning at large. Our account highlights potential drivers for such collaborative activity in other settings. In this way, we offer a means for others to develop the collective commitments, structures and understanding needed to mainstream SoTL within specific disciplinary or departmental settings.  相似文献   

A Review of: ““Doing School”: How We Are Creating a Generation of Stressed Out,Materialistic, and Miseducated Students”     

Matt Albert 《Journal of Jewish Education》2013,79(2):151-155

The views of Jewish education articulated by Rosenzweig in his essays “It is Time” and in “The Opening of the Lehrhaus” are quite different. So different, in fact, that an account of how one mind can produce such different accounts is necessary. Following the lead of a 1950’s popular television quiz show, the authors ask “Will the Real Franz Rosenzweig Please Stand Up?” The authors end by exploring how the tensions within Rosenzweig's educational thinking can yield new insights into the contemporary challenges of Jewish education.  相似文献   

Graphic Novels as Tools for Teaching Complexity About Israel     

Matt Reingold 《Journal of Jewish Education》2013,79(3):312-333

ABSTRACT

Building on the established idea that to provide students with a full portrait of Israeli society and history, educators must introduce greater complexity into their Israel curriculum, the following paper explores three recently published graphic novels about Israel and considers how each offers opportunities for considering Israel in more nuanced ways. The paper is grounded in recent research about Israel education and empirical studies about graphic novels in education. Each of the three texts highlights aspects of Israeli society that are less frequently addressed in curriculum about Israel and therefore provide opportunities for presenting students with primary sources that directly grapple with the complexities of Israeli society.  相似文献   

On the origin of microbial magnetoreception     

Wei Lin  Joseph L Kirschvink  Greig A Paterson  Dennis A Bazylinski  Yongxin Pan 《国家科学评论(英文版)》2020,7(2):472

A broad range of organisms, from prokaryotes to higher animals, have the ability to sense and utilize Earth''s geomagnetic field—a behavior known as magnetoreception. Although our knowledge of the physiological mechanisms of magnetoreception has increased substantially over recent decades, the origin of this behavior remains a fundamental question in evolutionary biology. Despite this, there is growing evidence that magnetic iron mineral biosynthesis by prokaryotes may represent the earliest form of biogenic magnetic sensors on Earth. Here, we integrate new data from microbiology, geology and nanotechnology, and propose that initial biomineralization of intracellular iron nanoparticles in early life evolved as a mechanism for mitigating the toxicity of reactive oxygen species (ROS), as ultraviolet radiation and free-iron-generated ROS would have been a major environmental challenge for life on early Earth. This iron-based system could have later been co-opted as a magnetic sensor for magnetoreception in microorganisms, suggesting an origin of microbial magnetoreception as the result of the evolutionary process of exaptation.  相似文献
