In this paper we present an online, collaborative process that facilitates usability evaluation of web sites. The online workspace consists of simple and effective proformas and computer–mediated discussion space to support usability evaluation. The system was designed and used by staff and students at two universities. Students, working in small teams, at each university, developed web sites and then evaluated the usability of web sites developed at the other university, using the results to improve their own sites. Our project evaluations show that the process provides valuable feedback on web site usability and provides students with the experience of usability evaluation from two important perspectives: those of a user and of a developer. Further, students develop important generic skills: the ability to participate in and critique computer supported cooperative work environments. 相似文献
Individuals in their mid-thirties are expected to be employed and economically independent. However, people with disabilities and health problems – for example, former students with special educational needs (SEN) – may have problems in this domain of adult life. In Norway, individuals with SEN frequently rely on social security and support measures from the Norwegian Labour and Welfare Administration (NAV). This article is based on the narrative analysis of life course trajectories of seven young adult males over a period of 17 years – from their enrolment in upper secondary school with special needs teaching whilst in their teens to their participation in various NAV programmes whilst in their mid-thirties. The life course approach, with an emphasis on transitions and trajectories, has been used as the theoretical framework for analysing the presented data. The hope is that, taken together, these seven stories provide a deeper insight than one individual story could offer. We find that both social structures and the earlier life course affect one’s opportunities for joining the labour market. 相似文献
The aim of this study is to investigate adolescents’ perspectives on mental healthcare services. Based on theoretical perspectives concerning barriers for help-seeking, individual interviews were carried out in order to obtain the adolescents’ perspectives on knowledge of services for mental health problems, potential barriers for help-seeking, and services to which they have access. The sample consisted of vocational students from an upper secondary school in the southwest of Norway (n = 8). None of the informants was currently in treatment for mental health problems. Interview data were transcribed and analysed with the assistance of NVivo Software. Qualitative content analysis indicated that the adolescents have limited knowledge of available resources, and, that stigma-related factors may prevent the adolescents from seeking help for mental health problems. Future directions for delivering mental health services for adolescents are given. 相似文献
In Experiment 1, rats received a session of 80 inescapable tail shocks or no shocks while restrained in a tube. During tests of conditioned defensive burying 24 h later, the bedding of the chamber contained odors from either stressed or nonstressed conspecific donor rats. Following a single prod shock, subjects that had had prior shocks or that were tested with the stress odors spent significantly less time burying the prod, made smaller piles of bedding, and displayed more freezing behavior. The combination of prior shock and stress odors during later testing enhanced these effects. In Experiment 2, a yoked group of rats that was given inescapable shocks, in contrast to a group that had wheel-turn escape training and one that was restrained but not shocked, later showed significantly less burying and more freezing when tested for defensive burying with stress odors present. In both experiments the duration of burying and the heights of piles were positively correlated, and both of these measures were negatively correlated with freezing. The demonstrated capacity of unconditioned stress odors to mediate different degrees of fear, depending upon the controllability of prior shock, is related to other studies of learned helplessness, and the predominance of freezing over burying is discussed in terms of various types of defensive strategies, stimulus-control processes, and the author’s stress-coping-fear-defense (SCFD) theory. 相似文献
How parents perceive their children's educational prospects can reveal a great deal about how their children will progress in the educational system. The paper examines the consequences of variations in inclusive education practices by investigating determinants of parents’ educational expectations for their child. All parents included in the study had children with physical disabilities in primary school (mainly cerebral palsy and spina bifida). The empirical material includes results from a survey (Net sample = 491), in combination with information merged from a range of official registers. The results showed that the more the child is segregated from ordinary classroom education, the lower parental expectations are for their children's educational attainments. Other factors also significantly influencing parents’ educational expectations include how parents’ view their child's school performance, as well as various measures of the severity of the child's physical disability. However, these secondary factors could not account for the empirically strong association between segregation practices and parental expectations. Parental expectations were also significantly related to parental income and education. The findings indicate that the expectations of parents with higher income and education are less affected by school segregation practices. 相似文献
To determine the aspects of an observational situation facilitating subsequent acquisition of an observed task, two experimental groups of rats were exposed to a model’s performance of a two-way discriminative shuttlebox avoidance task with a tone as the discriminative stimulus. One experimental group (OND) observed the performance of a naive demonstrator; the other experimental group (OSD) observed a skilled demonstrator. A stimulus control group (SC) was exposed to the tone with no model present; a response control group (RC) observed demonstrator running with no tone present. A naive control group (NC) received no observational experience. All groups were subsequently tested on acquisition of the task. An analysis of variance on avoidance scores and Newman-Keuls tests for differences between means revealed that OND and OSD groups performed significantly more avoidances than the control groups. Exposure to the total tone-running sequence was found to be necessary for observational learning. The results were interpreted in terms of a sensory-sensory conditioning model.
AbstractWe investigated academic buoyancy (a response to challenge) and adaptability (a response to change) among a sample of 12–16-year-olds in China (N = 3617) compared with same-aged youth from North America (N = 989) and the United Kingdom (UK; N = 1182). We found that Chinese students reported higher mean levels of buoyancy and adaptability. We also found that correlations between buoyancy and adaptability, and between these two factors and motivation and engagement outcomes, were significantly higher for Chinese students than for North American and UK samples. In path analyses, buoyancy and adaptability positively and significantly predicted motivation and engagement (typically at p < .001) in all three regions; however, buoyancy effects were significantly stronger for the Chinese students. 相似文献
