When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

In this study a synthesis of research into student learning at the individual level is used to derive a general categorisation rule that can be applied to individual study orchestrations. The term orchestration is introduced in this study to indicate that the association of constructs that represent approaches to studying at an individual level is a context-specific response and is affected by the qualitative level of perception of the individual towards certain key elements of learning context. In the first part of this study the association between context-dependent study orchestrations and learning outcome, and between deep perceptions of learning context and learning outcome, is established. In the second part of this study the general categorisation rule is empirically validated by means of an unfolding analysis that sets out to illuminate the variability of individual study orchestrations as well as the group study orchestrations of academic achievers and failures.It is concluded that learning outcome is associated with categorisations of individual study orchestrations/contextual perceptions. Furthermore, based on an unfolding analysis of academic achievers and failures, it is concluded that academic success is associated with a well defined meaning orchestration coupled with a holistic perception of learning context, while academic failure is associated with the disintegration of such an orchestration/perception.  相似文献

UNICEF’s new Millennium Development Goals and Beyond (2015. http://www.un.org/millenniumgoals/) focus on the needs of the largest marginalised minority, individuals with disabilities, challenging us to examine issues related to exclusion and develop strategies for making an authentic sense of belonging and high-quality early childhood education a reality for over 93 million children with disabilities (United Nations Children’s Fund. 2006. Convention on the Rights of Persons with Disabilities. http://www.un.org/disabilities/default.asp?id=150). A first step in addressing stigma and the exclusion of individuals with disabilities is to examine materials in environments, given that positive representation in books and media contributes to a sense of belonging, increased self-esteem, and greater understanding of and attitudes towards others. Historically, the portrayal of individuals with disabilities in the literature and media has been absent or negative while the number of children with disabilities in early childhood classes has steadily increased. In this study, the representation of individuals with disabilities in school materials was examined in 32 kindergarten classes using the Inventory of Disability Representation (Favazza, P. C., and S. L. Odom. 1997. “Promoting Positive Attitudes of Kindergarten-Age Children Toward People with Disabilities.” Exceptional Children 63: 405–418). Two classrooms (6%) had moderate representation, 22 classrooms (69%) had low representation, and 8 classrooms (25%) had no representation of disabilities. Implications for practice and research are presented in light of the current focus on disability rights and becoming a more inclusive society.  相似文献

In order to accomplish organizational goals within constraints, marketers need to develop and implement marketing strategies effectively and efficiently. Trainers equipped with human performance technology (HPT) skills and knowledge may contribute substantially to strategy development and implementation and eventually contribute to organizational success. In this article, we demonstrate how HPT improved retail sales performance in an organization in the Chinese telecom industry. The outcomes highlight the benefits of integrating HPT with marketing strategies and the importance of forming partnerships between training staff and marketing professionals.  相似文献

Motivation and emotional regulation are important for the sustained focused study and practice required for high levels of achievement and creative productivity in adulthood. Using the talent development model proposed by the authors as a framework, the authors discuss several important psychosocial skills based on the psychological research literature that are antecedent and concurrent to the types and level of motivation needed for transitions from ability to competence, competence to expertise, and beyond.  相似文献

The warm-up programme “FIFA 11+” has been shown to reduce football injuries in different populations, but so far veteran players have not been investigated. Due to differences in age, skill level and gender, a simple transfer of these results to veteran football is not recommended. The purpose of this study was to investigate the preventive effects of the “FIFA 11+” in veteran football players.

Twenty veteran football teams were recruited for a prospective 9-month (1 season) cluster-randomised trial. The intervention group (INT, n = 146; 45 ± 8 years) performed the “FIFA 11+” at the beginning of each training session, while the control group (CON, n = 119; 43 ± 6 years) followed its regular training routine. Player exposure hours and injuries were recorded according to an international consensus statement.

No significant difference was found between INT and CON in overall injury incidence (incidence rate ratio [IRR]: 0.91 [0.64–1.48]; P = 0.89). Only severe injuries reached statistical significance with higher incidence in CON (IRR: 0.46 [0.21–0.97], P = 0.04).

Regular conduction (i.e. once a week) of the “FIFA 11+” did not prevent injuries in veteran footballers under real training and competition circumstances. The lack of preventive effects is likely due to the too low overall frequency of training sessions.  相似文献

A content analysis of 4,507 tweets from 60 local news organizations in the United States was conducted to examine Twitter strategies used by the local news industry. Results indicate that local news organizations in the United States mainly used Twitter as an additional platform for news dissemination. While local TV stations and newspapers differed significantly in their use of tweet structures, content, and strategies, both followed the similar practices of their traditional media portals. In addition, the number of followers and total tweets of a news organization’s Twitter account, use of photos, hashtags, usernames, and tweet content predicted audience engagement with the site. Overall, local news organizations in the United States did not appear to use Twitter to cross-promote and/or supplement their traditional business practices. This research calls for more systematic, multi-dimensional social media management in local newsrooms.  相似文献

This study used the monozygotic (MZ) twin difference method to examine whether differences in friends' aggression increased the differences in MZ twins' aggression and depressive symptoms from kindergarten to Grade 1 and whether perceived victimization by the friend played a mediating role in this context. Participants were 223 MZ twin pairs. Results showed that differences in kindergarten friends' aggression significantly predicted an increased difference in MZ twins' aggression from kindergarten (mean age = 6.7 years) to Grade 1 (mean age = 7.5 years) for both boys and girls. Differences in perceived victimization by the friend mediated this association, albeit only in boys. Differences in perceived victimization by the friend also predicted an increase in MZ twins' differences in depressive symptoms. These results support the importance of friendship experiences during early childhood.  相似文献

Emotional/behavioral problems of 238 deaf Dutch children ages 4-18 years were studied. Parental reports indicated that 41% had emotional/behavioral problems, a rate nearly 2.6 times higher than the 16% reported by parents of a Dutch normative sample. Mental health problems seemed most prevalent in families with poor parent-child communication. Deaf children ages 12-18 showed more problems with anxiety and depression and more social problems than those ages 4-11. Deaf children with relatively low intelligence showed more social problems, thought problems, and attention problems than those with relatively high intelligence. The authors stress the need to get information on deaf children's mental health functioning not just from parents but from other informants such as teachers and the children themselves. An expansion assessment of deaf children, and of special services and treatments for deaf children and adolescents with emotional/behavioral problems, is recommended.  相似文献

Individual differences in academic success were investigated in a geographically defined whole-population sample of very preterm children with a gestational age of less than 32 weeks or a birth weight of less than 1500 gm. The sample consisted of 264 very preterm children (75.6% of German-speaking survivors) and 264 controls matched for gender, socioeconomic status, marital status and age of mother, who were studied from birth. The present analyses focused on the impact of cognitive skills assessed at ages 6 and 8 on academic success at the age 13. IQ scores, prereading skills, reading, spelling, and math performance assessed during the last kindergarten year and again at the end of Grade 2 were used as predictors of academic success in early adolescence. Differences between very pretern children and controls in cognitive abilities already observed in earlier assessments remained stable over time, with controls on average performing more than half a standard deviation above the level of preterm children. Preterm children also performed poorer on the literacy measures and indicators of math performance. Multivariate and causal modeling revealed different prediction patterns for the two groups. Whereas IQ was particularly important for the prediction of academic success in the pre-term sample, general IQ was less relevant for the prediction of academic success in the control group. When subgroups of at-risk children were formed according to birth weight categories, we found that school problems were most pronounced for children with extremely low birth weight (1000 gm and less).  相似文献
