Through collaboratively designed qualitative inquiry, we investigated the responses of high school students with learning disabilities to a teacher’s intervention intended to promote self‐realization, a fundamental component of self‐determination. Activities were embedded within the general English curriculum and delivered in a special education classroom over the course of an academic year. Several themes emerged from analysis of student interviews, student responses to writing prompts and surveys, a teacher journal, and student portfolio pieces. Silence and misconceptions were prevalent in student experiences. However, through the intervention students acquired information that helped them make sense of their school experiences, redefine themselves in positive ways, and take small steps toward greater self‐advocacy within their current school setting. The mediating influence of positive adult voices and concerns about social stigma were evident in students’ responses, which prompted us to question teachers’ and families’ responsibilities for engaging young people in dialogue about special education and disability. 相似文献

Abstract High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted in 10 cities from nine European countries in 2006-2008. Participants were 3288 adolescents (48% boys, 52% girls) aged 12.5-17.5 years with valid data on at least one of the three fitness variables studied: muscular strength (standing long jump), speed/agility (4×10 m shuttle run), and cardiorespiratory fitness (20 m shuttle run). The adolescents reported their relatives' physical activity engagement and encouragement. Analysis of covariance showed that relatives' physical activity engagement (father, mother, brother, and best friend) was positively related to cardiorespiratory fitness (P?0.05); and mother's and sisters' physical activity engagement were positively associated with higher muscular strength in adolescents (P?0.05). Furthermore, father's physical activity encouragement was positively linked to physical fitness (all fitness components) in adolescents (P?0.05). Interventions aimed at improving physical fitness in young people might be more successful when family members, particularly mothers and fathers, are encouraged to engage in physical activity and support adolescents' physical activity. 相似文献

Within Division I intercollegiate athletics, women hold 46.4% of graduate assistant and 47% of assistant athletic trainer positions, yet hold only 18.8% of head athletic trainer positions. The purpose of this study was to explore whether issues of power and gender stereotyping contribute to the lack of women in head athletic training positions in intercollegiate athletics. Data were gathered from 14 female athletic trainers at Division I universities through semi-structured interviews and follow-up questions based on those interviews and were analyzed using post-structural feminism as the theoretical framework. The findings revealed that male coaches used gender stereotypes to challenge the professional competence of our participants along with formal and informal work practices to reinforce power over the professional lives of our participants. 相似文献

Three studies investigated children's belief in causal determinism. If children are determinists, they should infer unobserved causes whenever observed causes appear to act stochastically. In Experiment 1, 4-year-olds saw a stochastic generative cause and inferred the existence of an unobserved inhibitory cause. Children traded off inferences about the presence of unobserved inhibitory causes and the absence of unobserved generative causes. In Experiment 2, 4-year-olds used the pattern of indeterminacy to decide whether unobserved variables were generative or inhibitory. Experiment 3 suggested that children (4 years old) resist believing that direct causes can act stochastically, although they accept that events can be stochastically associated. Children's deterministic assumptions seem to support inferences not obtainable from other cues. 相似文献

We review empirical research on English language learners (ELLs) who struggle with reading and who may have learning disabilities (LD). We sought to determine research indicators that can help us better differentiate between ELLs who struggle to acquire literacy because of their limited proficiency in English and ELLs who have actual LD. We conclude that more research is warranted to further elucidate the strengths and learning needs of subgroups of underachieving ELLs, to help us determine who should qualify for special education, and to clarify why some ELLs who do not have LD still struggle with language and literacy acquisition. Future research should account for the complexities involved in becoming literate in another language and focus more on cultural and contextual factors that affect student achievement. 相似文献

Background: To minimise retrieval bias, manual literature searches are a key part of the search process of any systematic review. Considering the need to have accurate information, valid results of the manual literature search are essential to ensure scientific standards; likewise efficient approaches that minimise the amount of personnel time required to conduct a manual literature search are of great interest. Objective: The objective of this project was to determine the validity and efficiency of a new manual search method that utilises the scopus ? database. Methods: We used the traditional manual search approach as the gold standard to determine the validity and efficiency of the proposed scopus method. Outcome measures included completeness of article detection and personnel time involved. Using both methods independently, we compared the results based on accuracy of the results, validity and time spent conducting the search, efficiency. Results: Regarding accuracy, the scopus method identified the same studies as the traditional approach indicating its validity. In terms of efficiency, using scopus led to a time saving of 62.5% compared with the traditional approach (3 h versus 8 h). Conclusions: The scopus method can significantly improve the efficiency of manual searches and thus of systematic reviews. 相似文献
