Pervasive socio‐economic differences in relation to participation in higher education in the United Kingdom are particularly prominent in the most prestigious institutions. This study provides insight into why some individuals from disadvantaged backgrounds are successful in being admitted into one of these institutions. Underpinned by phenomenology, semi‐structured interviews were carried out to examine the lived experiences of high‐achieving students from socio‐economically disadvantaged backgrounds throughout their educational trajectories from primary school to a Russell Group university. Two main themes emerged from the data: identity and educational engagement. Various sources of disadvantage associated with material hardship, socio‐cultural and interpersonal factors were strongly linked to identity and students’ perceptions of their own social status. In turn, these factors and identity‐related constructs associated with peer‐group memberships, low expectations and negative group stereotypes affected how individuals engaged with education, contributing, for instance, to their lack of active involvement at school/college and poor attendance. However, identity‐related factors were also found to influence individuals’ educational engagement positively, including their motivations for overcoming obstacles, achieving high grades and pursuing HE. The barriers and facilitators discussed by these individuals have important implications for widening access to HE and thus require further consideration.  相似文献

Viewing the American Dream as two myths, both essential to the identity and destiny of America, this essay argues that the 1972 presidential election required an endorsement of Nixon who represented a materialistic myth or of McGovern who personified a moralistic myth, that the outcome of this quadrennial ritual signified the way Americans want presently to conceive of themselves and suggests the way the American experiment may be going.  相似文献

Seven hundred thirty-one income-eligible families in 3 geographical regions who were enrolled in a national food supplement program were screened and randomized to a brief family intervention. At child ages 2 and 3, the intervention group caregivers were offered the Family Check-Up and linked parenting support services. Latent growth models on caregiver reports at child ages 2, 3, and 4 revealed decreased behavior problems when compared with the control group. Intervention effects occurred predominantly among families reporting high levels of problem behavior at child age 2. Families in the intervention condition improved on direct observation measures of caregivers' positive behavior support at child ages 2 and 3; improvements in positive behavior support mediated improvements in children's early problem behavior.  相似文献

ABSTRACT

Heart rate (HR), when combined with accelerometry, can dramatically improve estimates of energy expenditure and sleep. Advancements in technology, via the development and introduction of small, low-cost photoplethysmography devices embedded within wrist-worn consumer wearables, have made the collection of heart rate (HR) under free-living conditions more feasible. This systematic review and meta-analysis compared the validity of wrist-worn HR estimates to a criterion measure of HR (electrocardiography ECG or chest strap). Searches of PubMed/Medline, Web of Science, EBSCOhost, PsycINFO, and EMBASE resulted in a total of 44 articles representing 738 effect sizes across 15 different brands. Multi-level random effects meta-analyses resulted in a small mean difference (beats per min, bpm) of ?0.40 bpm (95 confidence interval (CI) ?1.64 to 0.83) during sleep, ?0.01 bpm (?0.02 to 0.00) during rest, ?0.51 bpm (?1.60 to 0.58) during treadmill activities (walking to running), while the mean difference was larger during resistance training (?7.26 bpm, ?10.46 to ?4.07) and cycling (?4.55 bpm, ?7.24 to ?1.87). Mean difference increased by 3 bpm (2.5 to 3.5) per 10 bpm increase of HR for resistance training. Wrist-worn devices that measure HR demonstrate acceptable validity compared to a criterion measure of HR for most common activities.  相似文献

To determine whether adolescents interpret parental behavioral and psychological control differently, type, level, and domain of control were manipulated across 3 interpretations (adolescents’ competence, mattering to parents, and parental intrusiveness). As expected, adolescents (N = 67, M = 14.25 years) generally interpreted high levels of behavioral control more negatively than moderate behavioral control. At high levels, however, adolescents did not differentiate behavioral control and psychological control, interpreting both as indicating less mattering and more intrusiveness. Furthermore, high levels of control over personal domain issues, regardless of type, tended to be interpreted most negatively. In conclusion, adolescents construe control in ways that may have import for their adjustment and this should be accounted for in theoretical models of parental control.  相似文献

Currently, we know very little about the mobility decisions of charter public school teachers and how these compare to the decisions made by traditional public school teachers. In addition, it is unclear whether the teachers who leave charter schools tend to be weaker or stronger than their peers. Using statewide administrative data, I begin to answer these questions by studying the magnitude and nature of teacher turnover in Florida's charter public schools compared with turnover in the state's traditional public schools. It appears that Florida's charter school administrators may be better able to recruit and retain teachers with high academic skills than their traditional counterparts. In addition, the mobility patterns exhibited by Florida's charter school teachers differ from those exhibited by traditional school teachers in important ways, including greater sensitivity to accountability measures and less sensitivity to salary considerations.  相似文献

The Physical Chemistry in Practice (PCIP) DVD contains video programs (modules) and experimental data that present the research of scientists working in applications of physical chemistry. The DVD allows students to learn about cutting edge research in physical chemistry while making connections to the theoretical concepts learned in lecture. PCIP-DVD allows students to build verbal and pictorial models of the experiments, instrumentation, and data that can be integrated with the material covered in lecture. For each of the modules implemented students were tested in a pre/post test fashion over content related objectives. For every module the students demonstrated a statistically significant improvement in their understanding.  相似文献

Considerable attention has been focused on the relationship between nonverbal communication behavior and student perceptions of the teacher. One important observation is that teachers frequently emit nonverbal messages that contradict their verbal ones, but the effects of this modal discrepancy are not well understood. In the present study, vocal cues are isolated as the nonverbal behavior for study. The interaction of vocal cues and verbal messages is examined with respect to its impact on teacher credibility. The results indicate that the students’ perceptions of sociability are influenced by perceived discrepancy between words and attitudes. Perception of competence, on the other hand, appears to be dependent on positive vocal cues.  相似文献

The present study explores the outcomes of teaching empathy and critical thinking to solve environmental problems. This investigation was done throughout the duration of an environmental education course within a primary school located in central Chile. A community-based research methodology was used to understand the formation of empathy and critical thinking. The findings reveal a significant benefit in using empathy strategies to engage students regarding the thinking processes involved with solving environmental problems. Using these elements as teaching techniques for environmental education courses can be very helpful in reaching the aims of creating a sustainable citizenry.  相似文献
