A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting.  相似文献   

Criminal Justice Education: Are We Missing One-third of the Crime Triangle?     

Lisa Growette Bostaph  Patrick Brady  Andrew Giacomazzi 《Journal of Criminal Justice Education》2014,25(4):468-485

Theoretical explanations, systemic response, and policy work on offenders and specific crime types are the backbone of criminal justice curricula in the United States. However, a similar breadth and depth of education on crime victims appear to be lacking in traditional criminal justice curricula, despite voluminous research on victims of crime. In this exploratory study, the authors conducted a content analysis of 679 programs from the Academy of Criminal Justice (ACJS) website directory. Departmental and course-level variables were included in the analysis. Results indicate that while more than half of the programs have faculty with expressed interests in victimization, only 11% of programs studied required coursework on crime victims and/or victimization. Implications of the results are discussed.  相似文献   

A Behind‐the‐Scenes Guide to School‐Based Research

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools.  相似文献   

A retrospective look at replacing face‐to‐face embryology instruction with online lectures in a human anatomy course          下载免费PDF全文

Embryology is integrated into the Clinically Oriented Anatomy course at the Texas Tech University Health Sciences Center School of Medicine. Before 2008, the same instructor presented embryology in 13 face‐to‐face lectures distributed by organ systems throughout the course. For the 2008 and 2009 offerings of the course, a hybrid embryology instruction model with four face‐to‐face classes that supplemented online recorded lectures was used. One instructor delivered the lectures face‐to‐face in 2007 and by online videos in 2008–2009, while a second instructor provided the supplemental face‐to‐face classes in 2008–2009. The same embryology learning objectives and selected examination questions were used for each of the three years. This allowed direct comparison of learning outcomes, as measured by examination performance, for students receiving only face‐to‐face embryology instruction versus the hybrid approach. Comparison of the face‐to‐face lectures to the hybrid approach showed no difference in overall class performance on embryology questions that were used all three years. Moreover, there was no differential effect of the delivery method on the examination scores for bottom quartile students. Students completed an end‐of‐course survey to assess their opinions. They rated the two forms of delivery similarly on a six‐point Likert scale and reported that face‐to‐face lectures have the advantage of allowing them to interact with the instructor, whereas online lectures could be paused, replayed, and viewed at any time. These experiences suggest the need for well‐designed prospective studies to determine whether online lectures can be used to enhance the efficacy of embryology instruction.

Fictitious Academic Expertise and Processing Resources     

Patrick Chambres  Rmy Versace  Catherine Auxiette 《Contemporary educational psychology》2001,26(4):507

A previous study showed that pairs of students interacting in a second language produced more words when they were assigned a fictitious expert position in a specific competence dimension than when they were assigned a nonexpert position. It has also been shown that the usual level of expertise has an impact on the assigned fictitious expertise effect. The present study was designed to determine whether the processing capacity allotted to the current task could partly determine performance. A given position of expertise may demand a large or small attentional capacity. Two experiments were conducted using a dual-task paradigm. As expected, the different expertise positions led to different reaction times on the secondary task. The second experiment showed that the impact of assigning a position of expertise to students depends on their usual academic standing. This study supports the idea that in interactive situations, performance variations as a function of the expertise position can be partially explained by differences in the processing resources allocated to the task. Implications for teaching are discussed.  相似文献

Individual differences in memory: Theory,data, and educational implications     

James M. Royer  Ronald K. Hambleton  Laurence Cadorette 《Contemporary educational psychology》1978,3(2):182-203

This paper examines two theoretical perspectives from which the issue of individual differences in memory can be viewed and relates the perspectives to evidence available in the literature. The paper also reports the results of two studies which bear upon the issue of whether there are individual differences in the retention of learned material. The last section of the paper examines the educational implications of one of the theories presented in the paper.  相似文献

Implementation planning and progress on physical activity goals: the mediating role of life-management strategies     

Dugas M  Gaudreau P  Carraro N 《Research quarterly for exercise and sport》2012,83(1):77-85

This 4-week prospective study examined whether the use of life-management strategies mediates the relationship between implementation planning and short-term progress on physical activity goals. In particular the strategies of elective selection, compensation, and loss-based selection were disentangled to assess their specific mediating effects. Results from a sample of 131undergraduate students showed that, as a composite, life-management strategies fully mediated the relationship between planning and goal progress. More specifically, decomposing the effects demonstrated that only elective selection and compensation mediated the association between planning and greater progress on a personal physical activity goal. Results are discussed in light of their practical implications and contributions to the personal goal literature.  相似文献
