Despite increased enrollment, outcomes such as grade point average (GPA), persistence, and graduation rates for college students with learning disabilities (LD) continue to lag behind those of their nondisabled peers. Reasons for the differences vary but may include academic and social integration, factors identified as important to the success of college students in general. This research investigated the relative influence of background characteristics, precollege achievement, and college integration variables on the academic success and intent to persist of college freshmen and sophomores with LD. While academic and social integration were not unique predictors of college GPA, both integration variables were unique predictors of intent to persist. The findings suggest that beyond high school achievement and background characteristics, college experiences as captured by academic and social integration are promising constructs to help explain the persistence of college students with LD. Implications for future research and practices for high school and college personnel are discussed. 相似文献

Transcribing sign communication used simultaneously with spoken English presents investigators with a unique problem: the singular quality of the bimodal communicative interactions cannot be accurately depicted using accepted conventions for recording either spoken or signed language samples. This article proposes guidelines for transcribing such data. The need for guidelines arose during an earlier study of the language development of a hearing child of deaf parents. To meet the immediate needs of that study, rules and conventions from previous studies were combined with newly generated ones, resulting in the guidelines proposed in this article. The guidelines can be applied to data in which intermodal linguistic influence is suspected. 相似文献

Human generated environmental problems are significant issues of global concern. Despite this, varying attitudes towards environments
continue to exist across the globe, impacting on environmental decision-making and action at local, national and international
levels. This paper probes some of the similarities and differences in environmental attitudes amongst pre-service teachers
in Australia, Republic of Maldives and Indonesia. Data were collected using an established environmental attitude questionnaire
and individual interviews. The three communities exhibited a similar range of environmental attitudes using the established
questionnaire but significant differences emerged when the interview data were analysed phenomenographically. These differences
reflect diversity within and across cultural groups that cannot be satisfactorily explained by the theory underpinning the
established questionnaire. Consequently, a revised conceptual framework is proposed. 相似文献
