Social class continues to be associated with achievement in school and attendance in university and higher education. This qualitative study explores this phenomenon, and reports three focus group interviews with middle and working class secondary school students, in Ireland. We explore cultural and identity factors in educational settings. Specifically, our analysis orients to the models of agency experienced by these students. Middle class participants express independent agency in education, through norms of choice, control, and freedom from constraints. In contrast, working class students orient towards an interdependent model of agency and express psychological, social, and material barriers to opportunity in education. However, independent neo‐liberal individualising and meritocratic discourses were expressed by both groups, suggesting the models are complicated and nuanced. Nevertheless, it is concluded that cultural fit and identity compatibility in educational settings, broadly, constitute middle class advantages and working class disadvantages. 相似文献

Joint attention is a pivotal social communication skill often absent or impaired in young children with autism spectrum disorder. Joint attention is the shared and alternating attention of two individuals on an object or event, and has implications for later communication and social communication skills. This study used a concurrent multiple‐baseline design across 3 caregiver–child dyads to train caregivers to teach response to joint attention behaviors to their 3–6 years old children with moderate to severe autism spectrum disorder. Caregivers were trained on strategies including prompting, time delay, and elements of naturalistic teaching and implemented the intervention in brief 10‐min sessions 2–3 times per week. Results indicate parent mastery of intervention and substantial increase in child response to joint attention behaviors both prompted and independent. Implications for practice and areas for future research are discussed. 相似文献

Researchers have evaluated how broad categories of emotion (i.e. positive and negative) influence judgments of learning (JOLs) relative to neutral items. Specifically, JOLs are typically higher for emotional relative to neutral items. The novel goal of the present research was to evaluate JOLs for fine-grained categories of emotion. Participants studied faces with afraid, angry, sad, or neutral expressions (Experiment 1) and with afraid, angry, or sad expressions (Experiment 2). Participants identified the expressed emotion, made a JOL for each, and completed a recognition test. JOLs were higher for the emotional relative to neutral expressions. However, JOLs were insensitive to the categories of negative emotion. Using a survey design in Experiment 3, participants demonstrated idiosyncratic beliefs about emotion. Some people believed the fine-grained emotions were equally memorable, whereas others believed a specific emotion (e.g. anger) was most memorable. Thus, beliefs about emotion are nuanced, which has important implications for JOL theory. 相似文献

Adolescence is a period characterized by continued improvements in inhibitory control, and this persisting immaturity is believed to interact with affective/motivational behavior to generate the impulsive and risk‐taking behavior evidenced at this time. Puberty is a central event of adolescence that has been shown to influence affective/motivational behavior. However, despite plausible mechanisms by which puberty might influence inhibitory control, researchers have yet to test this possibility rigorously. Thus, we designed a study to examine the unique role of pubertal maturation, independent of age, in the development of inhibitory control. In order to minimize age‐related variability while maximizing pubertal status variability, we recruited 78 participants (34 F) whose ages narrowly spanned the mean age of gonadarche for each sex (F: ages 11–13, M: ages 12–14). Two complementary measures were used to assess pubertal status: (1) circulating blood serum testosterone and estradiol levels reflecting internal manifestations of pubertal maturation, and (2) Tanner staging by a trained nurse reflecting pubertal maturation's external manifestations. Inhibitory control was assessed using the antisaccade task, and findings were adjusted for the potential effect of age. Results revealed no association between testosterone levels and error rates or response latencies in either sex. In girls, estradiol levels were not associated with error rates, but were associated with faster response latencies. There was similarly no association between Tanner status and error rates, although girls in more advanced pubertal stages showed faster response latencies. Power analyses indicate that findings of a lack of association did not reflect limited statistical power. Thus, in a study designed to isolate the effects of pubertal maturation independent of age, both external and internal indices of pubertal maturation converged to indicate that age‐related improvements in cold antisaccade performance are independent of pubertal maturation. 相似文献

This research was motivated by a clinical trial design for a cognitive study. The pilot study was a matched-pairs design where some data are missing, specifically the missing data coming at the end of the study. Existing approaches to determine sample size are all based on asymptotic approaches (e.g., the generalized estimating equation (GEE) approach). When the sample size in a clinical trial is small to medium, these asymptotic approaches may not be appropriate for use due to the unsatisfactory Type I and II error rates. For this reason, we consider the exact unconditional approach to compute the sample size for a matched-pairs study with incomplete data. Recommendations are made for each possible missingness pattern by comparing the exact sample sizes based on three commonly used test statistics, with the existing sample size calculation based on the GEE approach. An example from a real surgeon-reviewers study is used to illustrate the application of the exact sample size calculation in study designs. 相似文献

In this paper I explore how citizenship education might position students as always/everywhere political to diminish the pervasive belief that one either is or is not a “political person.” By focusing on how liberal and radical democracy are both necessary frameworks for engaging with issues of power, I address how we might reframe citizenship education to highlight the ubiquity of politics, offering a deepened sense of democracy. This reframing of citizenship education entails highlighting how liberalism and radical democracy are mutually reinforcing when it comes to illustrating political life as entangled in power relations. My argument centers on Sigal Ben-Porath’s (Edu Theory, 62(4):381–395, 2012) concept of shared fate as a frame for citizenship education. In this model, students are habituated into thinking of democracy as an “enduring pluralism” in which their fates are connected to that of their fellow citizens. In this paper I recast shared fate education in the singular to an education of shared fates in the plural. By doing so I theorize how citizenship education might construct citizenship as relational, emotional, embedded in power, and uncomfortable. 相似文献

The clinical advantages of the newborn screening programme (NBS) in the UK are well described in the literature. However, there has been little exploration of the psychosocial impact on the family. This study followed the principles of grounded theory to explore parents’ experiences of receiving the initial positive NBS result for their child with cystic fibrosis (CF) or sickle cell disease (SCD). Semi-structured, qualitative interviews were conducted with 22 parents (12 mothers and 10 fathers) whose children had been diagnosed with CF or SCD via NBS and were under the age of 1 year at the time of interview. The main themes that arose from the data were; parents previous knowledge of the condition and the NBS programme, the method of delivery and parental reactions to the result, sharing the results with others, the impact on parental relationships and support strategies. Study conclusions indicate that most parents thought initial positive NBS results should be delivered by a health professional with condition specific knowledge, preferably with both parents present. Genetic counselling needs to include a focus on the impact of NBS results on parental relationships. Careful consideration needs to be given to strategies to support parents of babies who have positive NBS results both in terms of the psychological health and to assist them in sharing the diagnosis. 相似文献
