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.

ObjectivesThis research explores the relationship between hypothesized protective factors and outcomes for children investigated for maltreatment.MethodsUsing data from the National Survey on Child and Adolescent Well-Being (NSCAW), we ran logistic regression models to examine the relationship between hypothesized protective factors (social competence, adaptive functioning skills, and peer relationships) and outcomes (externalizing behavior, internalizing behavior, reading competence).ResultsFor each hypothesized protective factor, we found variation in individual scores and sample mean scores at the lower end of the scales, indicating that these children fare worse than most children. However, many children experienced large changes in their individual scores over time suggesting that children can and do improve on these hypothesized protective factors. In examining the relationship between hypothesized protective factors and outcomes, children with higher levels of social competence were significantly more likely to be in the normal range for both externalizing and internalizing behaviors. Children with higher mean adaptive functioning skills were more likely to be in the normal range for both externalizing behavior and reading competence. The positive nature of the child's peer relationships was also related to externalizing behavior and reading competence.ConclusionsOverall, our analyses support the idea that social competence, adaptive functioning skills, and peer relationships are related to outcomes for children investigated for maltreatment. While further research is needed to establish a causal link, this work identifies three individual-level hypothesized protective factors as potential sources of variation in outcomes.Practice implicationsTo prevent or alleviate the harmful consequences maltreatment, it is necessary to understand factors that help children move beyond poor outcomes. Our analyses suggest that a strong relationship exists between a child's social competence, adaptive functioning skills and positive peer relationships and select outcomes three years after being investigated for maltreatment. With these individual-level protective factors related to more positive outcomes, it suggests that intervening to increase protective factors could improve outcomes for maltreated and at-risk children.  相似文献

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

This article focuses on (a) distinctions between the profoundly gifted individual and others, and (b) a chart describing tendencies and/or behaviors associated with the profoundly gifted student in common, mixed-ability educational settings. The intent is to provide educators, parents, and policymakers with preliminary awareness about the unique behaviors and tendencies of the profoundly gifted learner in heterogeneous educational settings. Learners with measured IQ scores greater than 3 SD units above the mean are a statistical rarity—outliers—in most educational settings. The current inability of most educators to identify and even minimally address needs leaves these students anxious, frustrated, and otherwise unable to reach their intellectual capacity in the majority of school settings across the country. Focused research and careful attention to the nature and needs of these individuals throughout their lives can contribute substantially to our developing understanding.  相似文献

The issue of sports mascot loyalty, especially to those mascots considered offensive, was investigated through fan identification theory, and applied to the mascot controversy at a large university in the United States. Replicating a previous university survey on the mascot question, a survey of current university students (N = 3616) revealed a strong relationship between mascot loyalty and fan identification, particularly related to one’s perceptions of ‘belonging to the university sports family’, and ‘associating with sports fans’ of the university. Other important findings include age differences and the marginalization of Asian-American fans. The implications and applications of these findings were discussed.  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

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

Abstract

Evidence 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
