Postsecondary institutions in the United States, including member institutions of the National Collegiate Athletic Association (NCAA), are charged with the responsibility of cultivating positive learning environments where all students have an opportunity to excel regardless of their demographic backgrounds (e.g., race, socioeconomic status, etc.). However, one subgroup of students these institutions have persistently been unable to retain and graduate at rates comparable to their peers is Black male student athletes. Previous research has cited unwelcoming campus climates, inadequate academic support, and an overemphasis on athletics as key factors that contribute to Black male student athletes' academic underperformance and negative psychosocial experiences at these institutions. The purpose of this article is to present a series of strategies and recommendations for enhancing Black male student athletes' educational experiences and holistic development at postsecondary institutions in the U.S. A review of scholarly literature on Black male student athletes, college student development theories, and student athlete support programs was conducted to identify best practices related to the phenomena. An analysis of the literature led to the creation of the Excellence Beyond Athletics (EBA) approach. The EBA approach consists of the following six holistic development principles (HDPs): (1) self-identity awareness, (2) positive social engagement, (3) active mentorship, (4) academic achievement, (5) career aspirations, and (6) balanced time management. 相似文献

There is an ongoing debate in the student evaluation of teaching literature about whether an overall rating or factorial dimensions of teaching effectiveness should be used in personnel decisions. Marsh and his colleagues have advocated the use of a weighted average approach to computing overall evaluations. A policy-capturing experiment was carried out where students in three different instructional contexts made overall evaluations of hypothetical instructors based on a manipulation of the teaching factors in Marsh's SEEQ. The results indicated (1) amount learned was consistently the most important factor affecting overall evaluations; (2) course difficulty was consistently the least important factor affecting overall evaluations; and (3) there was a strong similarity among the three groups in the relative importance of the various teaching factors in arriving at an overall evaluation. The implications of this research are discussed, as well as directions for future research. 相似文献

Protective behavioral strategies (PBS) are useful skills for reducing the negative consequences of alcohol. The moderating effects of anxiety on the relationship between 3 different types of PBS and negative consequences were examined among students accessing college counseling services. Results revealed a significant interaction between anxiety and strategies while drinking, suggesting that these simple strategies may be particularly beneficial among students who drink heavily and experience high levels of anxiety. Implications for counseling centers are discussed. 相似文献

In this article, we suggest that we are witnessing a challenge to the hegemony of text-based knowledge in academic scholarship, brought about by newly available modes of expression, and a cultural shift in our notions of reading and writing, authorship, and networked knowledge production. The central question we address here concerns the implications of widening our ideas of acceptable forms of inquiry, analysis and representation in academic scholarship. As a collective of scholar-practitioners exploring new modes of expression and working both within and outside the formal structures of academia, we argue for the increasing significance of multimodal research in the contemporary context of academic inquiry. By more equitably valuing different ways of thinking, knowing and communicating, multimodal research can facilitate wider and more diverse participation in the production of knowledge, offer a more nuanced and ethical mode of inquiry, emphasize different ways of knowing and connecting, and make scholarship more broadly accessible beyond academic contexts. Here, we analyze the key opportunities facilitated by multimodal inquiry, as well as the obstacles that stand in the way of a wider adoption of this type of research in higher education. 相似文献

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males. 相似文献

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important. 相似文献
