Although scholarly articles play an important role in the work life of academics, specific patterns of seeking and reading scholarly articles vary. Subject discipline of the reader influences many patterns, including amount of reading, format of reading, and average time spent per reading. Faculty members in different disciplines exhibit quite distinct patterns of reading. Medical/health faculty read more than others and mainly for current awareness purposes, while engineering faculty spend more time on average per article reading, and they also read more for research. Other factors that influence some reading patterns include work responsibilities (weighted towards more teaching or more research), age (young faculty are more likely to read on-screen from the open Web) and productivity of the reader, and purpose of the reading (readings for research and writing are more likely to be from a library collection). The ability to predict scholarly article seeking and reading patterns will assist journal editors, publishers, and librarians design better, more targeted journal systems and services. 相似文献

Believing that accountability could be a vehicle for change, the California Department of Education (CDE) requires all high
school students to pass the Calfornia High School Exit Exam (CAHSEE) in order to graduate. In doing so, California joins many
others states in mandating a high school exit exam as a current or future requirement for graduation. In this essay, the authors
will argue that this testing approach to school change is based on myths about the role of assessment, the information testing
can provide and the impact high stakes testing has on urban schools. Although California is the focus of this analysis, these
issues are salient across the county. Testing as a solution to poor student achievement is based on faulty assumptions. It
is these assumptions this piece seeks to address.

This article describes how a demonstration of statistical (or other) software can be recorded without expensive video equipment and saved as a presentation to be displayed with software such as Microsoft PowerPoint. Work carried out on a tablet PC, for example, can also be recorded in this fashion. 相似文献

Limited information exists about the movement patterns of field-hockey players, especially during elite competition. Time–motion analysis was used to document the movement patterns during an international field-hockey game. In addition, the movement patterns of repeated-sprint activity were investigated, as repeated-sprint ability is considered to be an important fitness component of team-sport performance. Fourteen members of the Australian men's field-hockey team (age 26±3 years, body mass 76.7±5.6?kg, [Vdot]O2max 57.9±3.6?ml?·?kg?1?·?min?1; mean±s) were filmed during an international game and their movement patterns were analysed. The majority of the total player game time was spent in the low-intensity motions of walking, jogging and standing (46.5±8.1, 40.5±7.0 and 7.4±0.9%, respectively). In comparison, the proportions of time spent in striding and sprinting were 4.1±1.1 and 1.5±0.6%, respectively. Our criteria for ‘repeated-sprint’ activity (defined as a minimum of three sprints, with mean recovery duration between sprints of less than 21?s) was met on 17 occasions during the game (total for all players), with a mean 4±1 sprints per bout. On average, 95% of the recovery during the repeated-sprint bouts was of an active nature. In summary, the results suggest that the motion activities of an elite field-hockey competition are similar to those of elite soccer, rugby and Australian Rules football. In addition, the investigation of repeated-sprint activity during competition has provided additional information about the unique physiological demands of elite field-hockey performance. 相似文献

Abstract The purpose of this study was to assess the agreement between two mobile cycle ergometer systems for recording high-intensity, intermittent power output. Twelve trained male cyclists (age 31.4 ± 9.8 years) performed a single 3 min intermittent cycle test consisting of 12 all-out efforts, separated by periods of passive recovery ranging from 5 to 15 s. Power output was recorded using a Polar S710 heart rate monitor and power sensor kit and an SRM Powercrank system for each test. The SRM used torque and angular velocity to calculate power, while the S710 used chain speed and vibration to calculate power. Significant differences (P < 0.05) in power were found at 8 of the 12 efforts. A significant difference (P = 0.001) was also found when power was averaged over all 12 intervals. Mean power was 556 ± 102 W and 446 ± 61 W for the SRM and S710 respectively. The S710 underestimated power by an average of 23% with random errors of ?/÷ 24% when compared with the SRM. Random errors ranged from 36% to 141% with a median of 51%. The results indicate there was little agreement between the two systems and that the Polar S710 did not provide a valid measure of power during intermittent cycling activity when compared with the SRM. Power recorded by the S710 system was influenced greatly by chain vibration and sampling rates. 相似文献

This study gives an overview of the history of required physical education in America's 4-year colleges and universities and provides an update on the requirement status. After randomly identifying 354 institutions, we searched their respective websites to determine whether physical education was a requirement to earn a baccalaureate degree. The major finding was that the physical education requirement declined from an all-time high of 97% in the 1920s and 1930s to an all-time low of 39.55% in 2010. Given society's ongoing health challenges and the important role of physical activity in maintaining health, this seems counterintuitive. It is also inconsistent with the National Physical Activity Plan (2010). 相似文献

AbstractEvidence suggests that the use of educational technologies may promote positive learning environments and contribute to students’ success. The following mixed methods study examined the impact of Top Hat in a blended learning environment on undergraduate students’ sense of belongingness, engagement, and self-confidence in a Canadian post-secondary institution. A survey study measured students’ sense of belongingness, engagement, and self-confidence before and after the course, which used Top Hat. The results show a significant increase in belongingness and self-confidence, but a decrease in engagement. Contrarily, focus groups revealed that using Top Hat may improve the overall learning experience. Limitations and future recommendations are discussed. 相似文献

Researchers have argued that Twitter has potential to support high-quality professional development (PD) that can respond to teachers’ questions and concerns just in time and “on the spot.” Yet, very little attention has been paid to instances where Twitter has made just-in-time learning possible. In this paper, we examine one instance of timely professional development on Twitter, in which 3,598 users used an educational hashtag—#educattentats—to create a temporary affinity space supporting French teachers preparing to discuss recent terrorist attacks with their students. We describe this just-in-time PD by focusing on participants and modes of participation, the spread of the hashtag in its first hours and the growth and eventual decline of the hashtag over the course of 28 days. The results of this study suggest that #educattentats served effectively as just-in-time professional development for teachers. Implications for research and practice are discussed. 相似文献

这个奶酪是什么? 在我们的生命中,我们都有一些想获得的东西--一份工作、一段关系、金钱、房子和家、自由、健康、获得认同、精神上的平静,或者是我们喜欢的活动,像是打高尔夫或是阅读。在这个故事中,"奶酪"是一种隐喻,代表了我们想要的这些东西,也就是吸引着嗅嗅、匆匆、哼哼和吱吱的这些东西,这些东西使他们快乐,充实了他们的存在。我们每个人对于我们的奶酪是什么都有自己的见解,我们追求它们,因为我们相信这些东西能使我们快乐。 相似文献
