Although there are many disagreements on the major causes of problems in the educational system in the United States, few would disagree that the importance of ensuring the success of our students is not only a moral obligation to our youth, but imperative to our national resilience. And, as a nation, we are responding to this urgent need. The College Completion Agenda mandates that 55% of the nation’s 25-to-35-year olds will be degree holders by the year 2025 (Lee & Rawls, 2010). But how do we accomplish the ambitious challenge and a necessary aspiration to elevate America’s status as a world leader in educational attainment among its citizenry? Innovative ideas and technologies that can counterbalance the barriers that threaten student success must be identified and advanced. The purpose of this article is to discuss the opportunity to leverage the marvel of online phenomena and technology in innovative ways to help students reach their full potential. Specifically, we introduce a new conceptual tool that replicates the power of social networking online matching services to link student learning preference with faculty instructional style. 相似文献

Articulation between two-year colleges and universities provides a critical opportunity for potential students. Most institutions declare their support of articulation; however, the visibility of this support to potential students is inconsistent at best. Articulation agreements that are visible and easily understood by potential students serve as a motivation to the pursuit of higher education. Conversely, the lack of a complete, visible path to a baccalaureate degree is a powerful deterrent to enrollment. For this study, articulation is a coordinated effort and process to support efficient transfer between institutions of higher education. (DeMott, 1999). The purpose of this study is to explore the general visibility of existing articulation opportunities at two-year colleges. The visibility of articulation agreements is a critical practical factor in their potential positive impact on student behavior and success. 相似文献

AbstractThis essay reads two differing conceptions of subjectivity in Frantz Fanon's work as corresponding to a shift in subjective orientation in certain moments of crisis, from what I term a unified individual – the subject of psychoanalysis – to a dispersed subject, the frenzied participant in collective activity. I believe that such a potential duality within the subject is best adopted when analysing Fanon's oeuvre, as well as when examining a subject's behaviour as participant in forms of unstructured collective protest such as rioting. Whereas the unified subject of psychoanalysis best expresses the consciously self-reflective individual in society, the dispersed subject expresses a subjectivity operating in excess of individualism. This dispersed subject acts collectively, as an object moving in tandem with other objects, without individual reflection. I argue that this shift comprises the initial spark of insurrection suggested in Fanon's work, the moment in which he sees the people pitched ‘in a single direction, from which there is no turning back’; and what Jean-Paul Sartre calls the explosive moment of ‘conflagration’. The two subject positions between which the subject shifts exist as two potential sides of every subject and comprise the ‘Manichean’ world in which Fanon's subject is entrenched. 相似文献

Abstract The home advantage is a widely acknowledged sporting phenomenon, especially in association football. Here, we examine the second leg home advantage, an effect that is discussed in the public domain but which has received very little scientific attention. The second leg home advantage effect occurs when on average teams are more likely to win a two-stage knock-out competition when they play at home in the second leg. That is, both teams have a home advantage but this advantage is significantly greater for the team that plays at home second. Examining data from three different European Cup football competitions spanning 51 years, we show that the second leg home advantage is a real phenomenon. The second leg home team has more than a 50% probability to qualify for the next round in the competition even after controlling for extra time and team ability as possible alternative explanations. The second leg home advantage appears, however, to have decreased significantly over the past decade. Possible reasons for its existence and subsequent decline are presented. 相似文献

Abstract The purpose of the present study was to assess the effectiveness of the triad components (amenorrhoea, disordered eating, and osteoporosis) in identifying physically active women at risk of long-term health problems. Eighty-two females (mean age 31.1 years, s = 6.7; body mass 58.4 kg, s = 6.6; stature 1.65 m, s = 0.06) completed training, menstrual, and dietary questionnaires. Bone mineral density and size-adjusted bone mineral density were assessed at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. Seventy-eight percent of participants were eumenorrhoeic, 20% were oligomenorrhoeic, and 2% were amenorrhoeic. Thirty-six percent and 55% reported disordered eating practices in the present and past respectively. Eighty-one percent, 17%, and 2% were classified as normal, osteopaenic, and osteoporotic at the femoral neck respectively; 92% were normal, 7% osteopaenic, and 1% osteoporotic at the lumbar spine. No significant differences in femoral neck size-adjusted bone mineral density were observed between eumenorrhoeic and oligo/amenorrhoeic participants (F 2,80 = 0.119, P = 0.73); eumenorrhoeic participants had significantly greater lumbar spine size-adjusted bone mineral density (F 2,80 = 9.79, P = 0.003). Disordered eating participants had significantly lower femoral neck size-adjusted bone mineral density than those reporting no disordered eating (F 2,80 = 13.816, P = 0.000). Twenty-two percent of participants fulfilled triad criteria, while 55% were “at risk” of long-term health problems. An accumulation of conditions resulted in lower lumbar spine size-adjusted bone mineral density (F 1,80 = 6.074, P = 0.004). The current triad components do not identify all women “at risk” and more appropriate criteria such as exercise-related menstrual alterations, disordered eating, and osteopaenia are suggested. 相似文献

There is evidence from previous cross-sectional studies that high volumes of certain sports, including running, swimming and cycling, may have a negative impact on bone mineral density. The aim of the present study was to evaluate prospectively the effects of high athletic training in individuals who engage in high volumes of all three of these activities (triathletes). Bone mineral density for the total body, arms and legs was determined by dual-energy X-ray absorptiometry in 21 competitive triathletes (9 men, 12 women) at the beginning of the training season and 24 weeks later. Age, body mass index, calcium intake and training volume were also recorded to examine potential mediators of bone mineral density change. Men had greater bone mineral density at all sites than women. No significant changes were observed over the 24 weeks for either total body or leg bone mineral density. Bone mineral density in both arms increased by approximately 2% in men ( P ? 0.03), but no change was observed for women. Change in bone mineral density at all sites was unrelated to age, body mass index, calcium intake and training volume. The results suggest that adverse changes in bone mineral density do not occur over the course of 6 months of training in competitive triathletes. 相似文献

Physical education teachers and the programs that prepare them find themselves in the early part of the 21st century in a public policy environment that differs significantly from that of the 20th century. This policy environment is grounded in an ideology that postulates that schools and teachers, rather than social forces, should be held responsible for academic outcomes, and in turn, economic success. For the first time, physical education teachers are being held accountable for student learning in the same way as their classroom peers. Improving the effectiveness of teachers is seen as the primary mechanism for improving student learning. In discussing how teaching effectiveness has evolved, I describe a relationship among the process–product paradigm, the ecological paradigm, and a neo-ecological paradigm called the instructional core. The latter paradigm extends our understanding of teaching effectiveness in new ways by describing the dynamic and interdependent relationship among teacher, student, and content in the gymnasium. It has significant implications for the professional development of teachers and the conduct of teaching effectiveness research. I conclude by discussing why content is so critical to conceptions of teaching effectiveness. 相似文献

Purpose The purposes of this study were to: (a) examine the effect of experience and goal constraints (speed, accuracy) on kicking patterns; (b) determine if effective striking mass was independent of ankle velocity at impact; and (c) determine the accuracy of kicks relative to independent factors. Method Twenty participants were recruited to kick at 3 different velocities with and without an accuracy requirement. Multivariate analysis of variance determined if relative timing of joint angular velocities changed during the kick. Chi-square analysis determined if calculated effective mass was independent of ankle velocity at impact. Analysis of variance (ANOVA) was used to examine differences in absolute constant error and variable error according to independent factors. Results Results indicated that experience and speed affect absolute timing of joint velocities with no changes in the relative timing of peak joint velocity across independent factors. Chi-square analysis indicated that calculated effective mass is not independent of ankle velocity. ANOVA indicated that experienced performers displayed less variability error than did inexperienced performers. Conclusion It was concluded that: (a) Experience, velocity, and accuracy do not affect the relative timing of kicks; (b) kickers trade ankle velocity at impact for greater effective striking mass and ball velocity; and (c) variability in ball placement is affected by experience. 相似文献

Faculty learning communities (FLCs) are collaborative collegial groups of faculty and other teaching staff who are interested in and committed to the improvement of their teaching to accommodate a diverse student population through group discourse, reflection and goal setting. In this article, we describe our FLC experiences that were supported by a federal grant to ensure accessible learning environments on our campus. The project, Ensuring Access through Collaboration and Technology (EnACT), sought to introduce faculty at a medium‐sized state university to a pedagogical framework to provide universal access to the curriculum for all students and to encourage faculty to adopt accessible technologies. We describe the recruitment process, the FLC meeting structure, our intended outcomes and the challenges we faced in meeting them. 相似文献
