Even though injury is common in elite sports, there is still a lack of knowledge of young athletes’ injury perception both during and after injury. The aim of this mixed-method study was, therefore, to explore, in-depth, data on injury consequences and adolescent elite athletes’ perceptions and experience of injury. Three hundred and forty adolescent elite athletes (age range 15–19), from 16 different sports, were bi-weekly monitored over 52 weeks using a valid questionnaire. Twenty athletes from the same cohort were interviewed in focus groups about injury experience and perceptions. The results show that the average bi-weekly prevalence of injury was 38.7% (95% CI 37.3–40.1), with 30.0% (n?=?102) of the athletes injured for more than half of all reporting times. An overarching theme from the focus groups highlighted the risk among young athletes of a loss of identity while injured. The findings support several suggestions that may improve the rehabilitation process and enhance rehabilitation outcomes: (a) provide clear pathways to the medical team, (b) recognize the identity loss, (c) involve the injured athletes with the rest of the teammates and (d) educate athletes about how to interpret pain signals. Future research should explore and evaluate the effectiveness and generalization of such interventions.  相似文献

In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education and open parent–child communication about sex have been shown to mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10–14 years and community-based strategies to enhance HIV prevention in Zambia. Focus group discussions were conducted with 114 young women in Zambian provinces with the highest rates (~20%) of HIV. Discussions were recorded, transcribed and coded, and addressed perceived HIV risk, knowledge and access to information. Participants reported that limited school-based sexuality education reduced opportunities to gain HIV prevention knowledge, and that cultural and traditional practices promoted negative attitudes regarding condom use. Parent–child communication about sex was perceived to be limited; parents were described as feeling it improper to discuss sex with their children. Initiatives to increase comprehensive sexuality education and stimulate parental communication about sexual behaviour were suggested by participants. Culturally tailored programmes to increase parent–child communication appear warranted. Community-based strategies aimed at enhancing protective sexual behaviour among those most at risk are essential.  相似文献

Research on the impact of the integration of technologies such as iPads on primary students’ attitudes and engagement in mathematics is limited. Further, there have been claims that teachers’ pedagogical choices can strongly influence the effectiveness of iPads for engaging students in mathematics. This paper presents an investigation of the influence of teaching and learning mathematics with iPads on students’ attitudes and engagement in mathematics. The participants in this study were students in a large urban primary school, implementing an iPad program for teaching and learning across the curriculum. Surveys with five-point Likert-type items were used to measure students’ attitudes to mathematics. Students from Years 2 to 6 completed the survey at the beginning and end of two consecutive school years. Survey results suggested that iPad use in mathematics has the potential to impact positively on students’ attitudes to mathematics. At the end of the second year of the study, semi-structured interviews were conducted with teachers and students. The interview responses confirmed that iPads had a positive influence on students’ engagement and attitudes to mathematics, and that the pedagogical approaches utilised by teachers for embedding iPads in their mathematics lessons contributed positively to these outcomes.  相似文献

Metacognition is increasingly recognized as important to learning. This article describes self-regulatory processes that promote achievement in the basic skills of reading and mathematical problem solving. Self-regulatory behaviors in reading include clarifying one's purpose, understanding meanings, drawing inferences, looking for relationships, and reformulating text in one's own terms. Self-regulatory behaviors in mathematics include clarifying problem goals, understanding concepts, applying knowledge to reach goals, and monitoring progress toward a solution. The article then describes the author's experiences integrating metacognition with reading and mathematics instruction and highlights students' reactions to learning to think metacognitively.  相似文献

A great deal of research shows that the way in which children attribute causes to their successes and failures in school has implications for the development of their academic self-concept (ASC). The most common attributions are ability, effort, task difficulty, and luck. The present study asked 68 elementary school children aged seven to eight years how they explained their successes and failures in school subjects. The aim of the study was to examine whether there were gender differences in the children’s responses which might indicate differences in ASCs or in their explanations for the causes of success or failure. Data were collected via quantitative questionnaires. Results showed no gender differences in ASC but, within the group, boys were more likely to attribute their success to high ability; on the other hand girls were more likely to attribute their failures to low ability or the difficulty level of task. This suggests that boys are more likely than girls to provide positive, self-enhancing reasons for their success while girls are more likely than boys to provide negative, self-deprecating reasons for their failures.  相似文献

Learning form errors seems to be crucial for talent development, but there is evidence that students learn little from their errors during school instruction. This work addressed the interplay of different adaptive reactions to errors (affective-motivational adaptive and action-related adaptive reactions), a positive error climate in the learning context and cognitive abilities with regard to their effect on academic achievement. A longitudinal data set with 2092 students attending 74 classes was analyzed with a two-level path modeling approach (students in classrooms). The results confirmed the assumption that affective-motivational adaptive reactions to errors encourage action-related adaptive reactions to errors which, in turn, foster academic achievement. Furthermore, analyzes indicated that the relationship between a positive error climate in the classroom and academic achievements is mediated by students’ individual reactions to errors. In contrast to expectations, students with higher cognitive abilities did not show more adaptive reactions to errors.  相似文献
