A view of science as a culturally‐mediated way of thinking and knowing suggests that learning can be defined as engagement with scientific practices. How students engage in school science is influenced by whether and how students view themselves and whether or not they are the kind of person who engages in science. It is therefore crucial to understand students' identities and how they do or do not overlap with school science identities. In this paper, we describe four middle school African American girls' engagement with science. They were selected in the 7th grade because they expressed a fondness for science in school or because they had science‐related hobbies outside of school. The data were collected from the following sources: interviews of students, their parents and their teachers; observations in science classes; journal writing; and focus groups. These girls' stories provide us with a better understanding of the variety of ways girls choose to engage in science and how this engagement is shaped by their views of what kind of girl they are. © 2000 John Wiley & Sons, Inc.

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 compares the examination performance of students following General Certificate of Secondary Education Applied Science and Double Award science on a value‐added basis. It uses data from the National Pupil Database, which are analysed by a variety of methods, including multilevel modelling. It argues that the claims made within Office for Standards in Education reports on the impact of the new Applied Science course are inaccurate, and in some cases positively wrong. The authors' analysis, based on the second (2003–05) cohort of students following the course, shows that students of lower attainment at Key Stage 3 appear to perform better than would have been predicted from their Key Stage 3 attainment, but that higher attaining pupils perform less well. Schools offering Applied Science show greater diversity in the value‐added effects they produce than they do with Double Award science. The article argues that analyses of this kind are of value in seeking to understand the impact of curriculum reform, but that they are dangerous as a generalized guide for policy. They must be complemented by work in schools in which the sources of the effects observed and of school diversity are examined. 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

In baseball and softball, there is a rule that allows the home team to have the last at-bat and thus the final opportunity to win the game. However, in tournament play, this rule is often set aside and, instead, batting order is decided by other means (e.g. tournament rules, the flip of a coin). The purpose of this study was to examine the impact of the batting last rule on game outcome in NCAA men's regional tournament baseball. It was hypothesized that host (i.e. home) teams would win a greater percentage of the games in which they batted last compared with when they batted first. This hypothesis was not supported. Closer examination of the last inning of play showed home teams were no more likely to have won the game during their last bat than visitors playing other visitors. The results suggest that the batting last rule contributes minimally, if at all, to home advantage in NCAA tournament baseball. 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
