The analysis and forecasting of male cycling time trial records established within England and Wales
The format of cycling time trials in England, Wales and Northern Ireland, involves riders competing individually over several fixed race distances of 10–100 miles in length and using time constrained formats of 12 and 24 h in duration. Drawing on data provided by the national governing body that covers the regions of England and Wales, an analysis of six male competition record progressions was undertaken to illustrate its progression. Future forecasts are then projected through use of the Singular Spectrum Analysis technique. This method has not been applied to sport-based time series data before. All six records have seen a progressive improvement and are non-linear in nature. Five records saw their highest level of record change during the 1950–1969 period. Whilst new record frequency generally has reduced since this period, the magnitude of performance improvement has generally increased. The Singular Spectrum Analysis technique successfully provided forecasted projections in the short to medium term with a high level of fit to the time series data. 相似文献

This article describes an untapped resource that counselors can use to help serve the multiple needs of college students recovering from addiction: collegiate recovery programs. The authors provide detailed information about the collegiate recovery population and give examples of successful programs. Implications for future research are discussed, and suggestions are provided for facilitating student recovery and advocating for collegiate recovery programs. 相似文献

AbstractThis issue is the second of a special PRIMUS two-part issue collecting articles on undergraduate research from experienced faculty mentors. We offer it as a valuable resource for faculty leading undergraduate research programs. This issue presents a collection of papers offering advice on a variety of specific topics important for leaders of undergraduate research programs. Issues of finding and designing appropriate and accessible research projects, assessing undergraduate research, and publicizing it in the media are addressed. 相似文献

This study investigated differences in peer and student?faculty relationships of male and female community college students. Men reported more frequent participation in college activities, whereas women reported more frequent involvement in less formal activities such as studying with other students. Women had less difficulty than men meeting and making friends. For both men and women, little student?faculty interaction outside the classroom was reported. 相似文献

While community colleges serve as a postsecondary entry point for many “at-risk” students, not many who enroll will be ready or able to participate in college level courses on entry. Statistically, large numbers of community college students require college remediation, and only a handful are able to successfully emerge from the remediation pipeline. Many students find mathematics the most challenging course sequence and frequently report high levels of math anxiety and lower completion rates. Using population data from a large urban district in a western state, this study examined the impact of course grades on subsequent grades within math courses. 相似文献

ABSTRACT In this article, the authors introduce a novel way, using the metaphor of a baseball game, to evaluate and measure community college student progress for those whose stated goal is to transfer to a 4-year institution and, ultimately, earn a bachelor's degree. The proposed framework of “the Transfer Game” is an outgrowth of the Transfer and Retention of Urban Community College Students (TRUCCS) project, which is a longitudinal study of 5,000 community college students from the 9-campuses of the Los Angeles Community College District. The goal of the project is to explain how the “all-American game” provides a method to measure, comprehend, and visualize student progression, and identify the factors that predict both success and barriers. The framework provides a scholarly comparison of the all-American game of baseball to the All-American invention of the community college. 相似文献

Researchers and practitioners alike express concerns about the conceptual difficulties associated with the concepts of momentum and kinetic energy currently taught in school physics. This article presents an in‐depth analysis of the treatment given to them in 44 published textbooks written for UK secondary school certificate courses. This is set against some of the more contentious issues apparent in the literature concerned with the underlying physics and pedagogical arguments about how best to help students understand. The research evolved a set of criteria which were used to scrutinize how texts explain ideas and exemplify their applications. Despite the evident merits of many textbooks, the findings suggest that incomplete explanations are surprisingly prevalent, with several fundamental issues likely to be unclear to student readers, particularly those relating to when and where conservation might apply. Confusion exists between these difficult and somewhat overlapping ideas, arguably through the neglect of constructivist considerations. The commonly emphasized mechanistic, number‐crunching approach to the analysis of simple collision problems is judged to be un‐profitable, underlining the more general point that prevailing, accepted content and pedagogy may be the source of many misunderstandings. Implications are discussed and suggestions made for alternative treatments of these deceptively complex topics. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 739–761, 2009 相似文献
