The effects of task constraints on visual search behavior and decision-making skill in youth soccer players 总被引:1,自引:0,他引:1
We examined differences in visual search behaviors and decision-making skill across different microstates of offensive play in soccer using youth participants (13.0-15.8 years) varying in skill and experience. We used realistic film simulations of offensive play, movement-based response measures, and an eye movement registration technique. Playing experience, skill level, and the unique constraints of the task, expressed by the number of players and relative proportion of offensive and defensive players, determined both the observed search behavior and processing requirements imposed on players in dynamic offensive team simulations. Significant differences in performance were observed between players and nonplayers and across three groups of soccer players who differed in skill level. Implications for talent identification and development are considered. 相似文献

The phenomenon in which students enter university under-prepared for the mathematical demands of their undergraduate courses, regularly referred to as the ‘Maths Problem’, has been widely reported in Ireland, UK, Australia, and the US. This issue has been of particular concern in Ireland recently, with beginning undergraduates’ performance of basic mathematical skills showing signs of significant decline in recent years. New mathematics curricula, commonly referred to as ‘Project Maths’, were gradually introduced into the Irish secondary school education system from 2010 onwards. These new curricula aim to place greater emphasis on student understanding of mathematical concepts, use of contexts, and applications of mathematics. This study analyses, through mathematics diagnostic test data gathered between 2008 and 2014, the change in the basic mathematical skills of beginning undergraduates over the time period in which the new mathematics curricula were introduced to secondary education in Ireland. It was found that students’ basic mathematical skills have declined over the time period during which the new mathematics curricula were introduced. Significant declines in beginning undergraduates’ performance of basic mathematical skills were observed during the period 2008–2014, particularly among students who have achieved Higher Level C grades and Higher Level D grades. 相似文献

Alongside debates concerning managerialism, marketisation and performativity, the question of accountability in higher education has come to the fore in recent commentary. Discussion of the subject has tended to be divided into two distinct camps. On the one hand, there are strong calls for more accountability to the public purse – a desire to witness more productive returns and efficiency on investment in higher education. On the other, there are academics who rail against the oppressive, panoptican‐like nature of the audit culture, emphasising the debilitating effects of quality assurance mechanisms on academic life. The paper suggests that one way out of this impasse is to place the current accountability agenda – what Travers refers to as the ‘new bureaucracy’ – in the context of Max Weber's account of bureaucracy and rationality. Habermas' reconstructed version of Weber's work is identified as a possible means of delineating the reaches and limits of modern bureaucratic accountability. 相似文献

This multiple case study examined pre-service teachers perceptions of effective post-secondary instruction. Pre-service teachers
were asked to write essays describing an effective teacher of their choice. Twenty-one essays were randomly selected. Data
analysis involved open coding of each essay, content analysis of each essay using Anderson and Burns’ (Research in classrooms:
The study of teachers, teaching, and instruction (1st ed.). Oxford, England; New York: Pergamon Press, 1989) empirically derived
dimensions of instruction, and effect size analysis of student and teacher roles. Instructional components were identified
that differentiate between effective inquiry instruction and effective instruction. Effective inquiry instruction was associated
with more and different teacher and student roles, more activities as part of instruction, and more student small group discussion
than was effective instruction. 相似文献

The altruistic act of body donation provides a precious resource for both teaching and researching human anatomy. However, relatively little is known about individuals who donate their bodies to science (donors), and in particular whether donors in different geographical locations share similar characteristics. A multicenter prospective survey of donors registering during 2010 in three different geographical locations, New Zealand, Ireland, and the Republic of South Africa, was conducted to identify donor characteristics. The 28-question survey included sections on body donation program awareness, reasons for donating, giving tendency, education, ethnicity, relationship status, occupation, religion, and political preference. Two hundred surveys (81%) were returned [New Zealand 123 (85% response rate), Republic of South Africa 41 (67%), and Ireland 36 (92%)]. Results indicate that donors share certain characteristics including reason for donating (80% cited a desire to aid medical science as the main reason for wishing to donate their body); family structure (most donors are or have been in long-term partnerships and ≥ 85% have siblings); and a higher proportion with no religious affiliation compared to their reference population. Some variations between locations were noted including donor age, the mode of program awareness, occupation, relationship status, political preference, organ donor status and with whom donors had discussed their decision to donate. This information could be important for assisting the identification of potential body donors in new and established bequest programs. 相似文献

Recent advances involving high-throughput techniques for data generation and analysis have made familiarity with basic bioinformatics concepts and programs a necessity in the biological sciences. Undergraduate students increasingly need training in methods related to finding and retrieving information stored in vast databases. The rapid rise of bioinformatics as a new discipline has challenged many colleges and universities to keep current with their curricula, often in the face of static or dwindling resources. On the plus side, many bioinformatics modules and related databases and software programs are free and accessible online, and interdisciplinary partnerships between existing faculty members and their support staff have proved advantageous in such efforts. We present examples of strategies and methods that have been successfully used to incorporate bioinformatics content into undergraduate curricula. 相似文献

Black males, as one non-dominant population, remain underrepresented and less successful in science, technology, engineering, and mathematics (STEM). Researchers focused on non-dominant populations are advised against generalizations and to examine cultural intersections (i.e. race, ethnicity, gender, and more) and also to explore cases of success, in addition to cases of under-achievement and underrepresentation. This study has focused on one African American male, Randy, who expressed high-achieving STEM career goals in computer science and engineering. Furthermore, recognizing that culture and identity development underlie STEM engagement and persistence, this long-term case study focused on how Randy developed a STEM identity during the course of the study and the implications of that process for his STEM career exploration. Étienne Wenger’s (1999) communities-of-practice (CoP) was employed as a theoretical framework and, in doing so, (1) the informal STEM program in which Randy participated was characterized as a STEM-for-social-justice CoP and (2) Randy participated in ways that consistently utilized an “economics” lens from beyond the boundaries of the CoP. In doing so, Randy functioned as a broker within the CoP and developed a non-traditional STEM identity-in-practice which integrated STEM, “economics”, and community engagement. Randy’s STEM identity-in-practice is discussed in terms of the contextual factors that support scientific identity development (Hazari et al. in J Res Sci Teach 47:978–1003, 2010), the importance of recognizing and supporting the development of holistic and non-traditional STEM identities, especially for diverse populations in STEM, and the implications of this new understanding of Randy’s STEM identity for his long-term STEM career exploration. 相似文献

Recent evidence from this laboratory suggests that a context switch after operant learning consistently results in a decrement in responding. One way to reduce this decrement is to train the response in multiple contexts. One interpretation of this result, rooted in stimulus sampling theory, is that conditioning of a greater number of common stimulus elements arising from more contexts causes better generalization to new contexts. An alternative explanation is that each change of context causes more effortful retrieval, and practice involving effortful retrieval results in learning that is better able to transfer to new situations. The current experiments were designed to differentiate between these two explanations for the first time in an animal learning and memory task. Experiment 1 demonstrated that the detrimental impact of a context change on an instrumental nose-poking response can be reduced by training the response in multiple contexts. Experiment 2 then found that a training procedure which inserted extended retention intervals between successive training sessions did not reduce the detrimental impact of a final context change. This occurred even though the inserted retention intervals had a detrimental impact on responding (and, thus, presumably retrieval) similar to the effect that context switches had in Experiment 1. Together, the results suggest that effortful retrieval practice may not be sufficient to reduce the negative impact of a context change on instrumental behavior. A common elements explanation which supposes that physical and temporal contextual cues do not overlap may account for the findings more readily. 相似文献
