A growing body of research has found that student-teacher race match is associated with higher test scores, teacher expectations, and teacher perceptions of students. This paper contributes to the student-teacher race match literature by investigating the effect of race match on course grades. To the extent that race match is associated with higher course grades for minority students, a more diverse teacher workforce is one mechanism that may help to narrow the achievement gap. Using a series of fixed effects models exploiting within-student variation across year and subject matter, I find that having a race-matched teacher is associated with a small but significant increase in course grade, on average. The positive effect of race match is driven largely by the experience of Black students. 相似文献

In two experiments with rat subjects, we examined the effects of a retention interval on performance in two conditioning paradigms in which a conditioned stimulus (CS) was associated with different unconditioned stimuli (USs) in successive phases of the experiment- Experiment 1 was designed to examine aversive-appetitive transfer, in which the CS is associated with shock and then food; Experiment 2 was designed to examine appetitive-aversive transfer, in which the CS is associated with food and then shock. Aversive and appetitive conditioned responses (freezing and head-jerk responding, respectively) were scored from videotape. In both experiments, a 28-day retention interval following the end of Phase 2 caused a recovery of the Phase 1 response and a resuppression of the Phase 2 response. The results suggest that the original association is not destroyed when the CS is associated with a new US in Phase 2. They also suggest that both retroactive and proactive interference effects may result-from interference with performance output rather than a disruption or loss of what is learned during or stored from the target phase. 相似文献

The inclusion of games in mathematics programmes is widely believed to foster the enjoyment of mathematics. The focus of this paper is on fluctuations in emotional climate during the playing of whole-class mathematics games. A multimethod approach drawing on the sociology of emotions was employed to explore changes in the classroom emotional climate that were associated with game playing. The event-oriented inquiry was conducted with two teachers and a class of 10- to 13-year-olds in a New Zealand classroom during mathematics sessions. Over a series of eight mathematics lessons, there were three noticeable fluctuations in emotional climate, all of which occurred during whole-class games. Our analysis of these three events identified a successful interaction with dramatic emotional energy associated with a positive emotional climate, a successful interaction with undramatic emotional energy associated with positive emotional climate, and an unsuccessful interaction associated with negative emotional climate with interactional repair. The third event also illustrated how the incomplete nature of a game’s rules can provide an opportunity for a negative emotional climate to be associated with game playing. The taken-for-granted wisdom that whole-class mathematics games can enhance emotional aspects of a classroom learning environment is supported by some of our evidence.

Previous work has shown that mothers' employment is associated with increases in children's body mass index (BMI), a measure of weight for height. Nonstandard work (working evenings or nights, weekends, or an irregular shift) may also be associated with children's BMI. This article examines the association between maternal work and children's BMI and considers the influence of mothers' nonstandard work schedules. Using data from school-age children (approximately 8 to 12 years) in the NICHD's Study of Early Child Care and Youth Development (N = 990), this study found that an increase in the total time a mother is employed is associated with an increase in her child's BMI; additionally, the association between maternal employment and children's weight is much stronger at 6th grade relative to younger ages. There was no evidence that maternal or home characteristics or children's time use mediated these associations, nor was there any evidence that nonstandard work was associated with children's BMI. Implications for policy and future research are discussed. 相似文献

To identify social schemas that are associated with self-esteem in adolescence, the contents of approximately 1,400 memories from a longitudinal sample of 41 males and 43 females were correlated with a Q-sort measure of self-esteem. Each memory concerned an important or problematic encounter, and was coded for social motive, affect, and identity of significant other. For young women, memories about wanting to help female friends were associated with chronically high and increasingly high levels of self-esteem from ages 14 to 23. For young men, memories about successfully asserting oneself with male friends were associated with chronically high and increasingly high levels of self-esteem. Low self-esteem in women, both chronic as well as decreasing, was associated with memories about failing to get approval from friends. Decreasing self-esteem for males was associated with memories about wanting love from female friends. The results confirm and refine prior findings that adolescent self-esteem is localized in relationships with peers rather than parents, and is based on different relational schemas for females than for males. The findings may help to identify contexts for preventative interventions to enhance adolescent self-esteem. 相似文献

Evidence shows that teachers’ use of information and communication technology (ICT) in the classroom is still limited in variety and frequency. However, their use of ICT outside the classroom, while more frequent, has been less studied. Our research aims to identify personal factors associated with teachers’ ICT use inside and outside the classroom. Data from a questionnaire administered to a nationwide sample of 6932 teachers in Chile was used to characterise their activities and perceptions associated with ICT. Multiple regression analyses were applied to determine relationships between them. The findings show first, that teachers use ICT more frequently outside the classroom for class preparation; second, that their perceptions of ICT impact on professional practice is the main factor associated with their use of ICT inside and outside the classroom; third, that less experienced teachers use communication tools with colleagues and students more often; and finally, that there is a need to examine teachers’ use of (ready-made) Internet resources. 相似文献

Prior research on Pavlovian-to-instrumental transfer has shown that when a CS previously associated with shock (AvCS+) is presented contingent upon a choice response to a discriminative stimulus for food reinforcement, it facilitates discrimination learning. Conversely, a response-contingent CS previously associated with the absence of shock (AvCS?) retards discrimination learning. To evaluate whether these findings reflect across-reinforcement blocking and enhancement effects, two experiments investigated the effects of appetitively conditioned stimuli on fear conditioning to a novel stimulus that was serially compounded with the appetitive CS during conditioned-emotional-response (CER) training. Although there were no differential effects of the appetitive CSs in CER acquisition, Experiment 1, using a relatively weak shock US, showed that a CS previously associated with food (ApCS+) retarded CER extinction to the novel stimulus, in evidence of enhanced fear conditioning to that stimulus. In addition, Experiment 2, using a stronger shock US, showed that a CS previously associated with the absence of food (ApCS?) facilitated CER extinction to the novel stimulus, in evidence of weaker fear conditioning to that stimulus. These results parallel traditional blocking effects and indicate not only that an ApCS+ and an ApCS? are functionally similar to AvCSs of opposite sign, but that their functional similarity is mediated by common central emotional states. 相似文献

Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval. 相似文献

Lashley and Rosellini (1980) have recently suggested that schedule-induced polydipsia (SIP) is determined by the occurrence of absolute periods within schedules of periodic food delivery which are associated with a low probability of food delivery, that is, CS? periods. To assess this hypothesis, SIP was examined in the present experiments under three schedules—fixed time, variable time, and random time (RT)—which differed in probability of occurrence and/or duration (Experiment 1), and under a range of RT schedules in which the CS? period was systematically varied by changing the interpellet interval (Experiment 2). In both experiments, the level and temporal distribution of SIP did not seem to be related to the absolute period associated with the absence of food. Instead, SIP was more systematically related to the average length of the interpellet interval and, therefore, to the average period associated with no food. It was suggested that drinking under intermittent schedules of pellet delivery, that is, SIP, is determined by an average CS? period and not by an absolute period associated with the unavailability of food. 相似文献

A model is proposed for identifying latent predictor score patterns associated with a latent outcome variable. The model employs 2 new devices: (a) a path coefficient vector of contrast coefficients to describe a configural pattern in a structural model, and (b) a new type of latent variable with values that quantify the match of the person's latent predictor variable profile pattern to a theoretical pattern associated with the factor. The model is illustrated using data on perceptions and evaluations of political candidates during a debate. Findings suggest a pattern of scores on the perceptual variables associated with perceived debate success for female observers but not for male observers. 相似文献

BACKGROUND: Foreign body aspiration in children is commonly seen in emergency departments and carries a significant mortality. Abusive foreign body suffocation is not well described. METHODS: We present a case-series of four infants who presented with aspiration of a baby wipe. RESULTS: Each child was found to be a victim of child physical abuse with substantial morbidity and mortality associated with the aspiration of the wipe and associated injuries. CONCLUSIONS: We recommend that infants who present with a baby wipe aspiration should be considered as likely victims of child abuse and physicians should evaluate each infant for associated injuries of the oropharynx, skin, skeleton, and head. 相似文献

Universities have recently strengthened their class attendance policies along with associated practices that intensify the surveillance of learning: a series of administrative and pedagogic strategies that monitor the extent to which students conform with behavioural expectations associated with learning. Drawing on university policy statements, the paper identifies implicit arguments underpinning attendance requirements for students in higher education. These include demonstrating the accountability of publicly funded higher education, a concern for the pastoral and academic welfare of students and their appropriate preparation for expectations associated with workplace and professional practice. In a critique it is argued that attendance policies promote presenteeism as part of the discourse of learnerism. Such rules further infantilise students rather than developing their capacity to make informed choices as adults thereby failing to respect their academic freedom. 相似文献

This article describes a group of Druze preschool and kindergarten teachers from Northern Israel who participated in an in-service
course in their community. The focus of the training experience was to improve the social climate of the classroom by implementing
a life-world approach. Analysis of their reports shows that the children’s meaningful learning, improved emotional coping
with ordinary hardships, and mutual social support are a product of intervention that involves multiple, interrelated activity
channels: staff collaboration, guided small group discussions, informal discussions, cooperation with parents and community
agents, and free play. Each activity channel is associated with a compatible, dominant, learning modality and a predominant
interpersonal process—free play, for example, is mainly associated with free inquiry and discourse among children, whereas
group activity is also likely to be associated with learning guided by educators. 相似文献

Is attachment theory a good fit for explaining differences in relationship maintenance? This study hypothesized that the secure attachment style would be positively associated with self-reported relationship maintenance, and that the dismissive style would be negatively associated with self-reported relationship maintenance. Further, it was proposed that individuals with negative views of others would be less likely to perceive their partner's use of maintenance. Survey data were collected from 179 married individuals. Results supported an attachment theory explanation for self-reported maintenance; a dismissive attachment was negatively associated with maintenance, and a secure attachment style reported was positively associated with maintenance. The fearful avoidant and preoccupied attachment styles were positively associated with the use of assurances, and negatively associated with the use of integrative conflict management and positivity. Finally, a dismissive attachment style was negatively associated with the perception of the partner's use of maintenance. 相似文献

This paper presents evidence from a nationally representative sample of early career teachers about those likely to miss out on formal support, and the employment conditions associated with this absence of support. It uses survey data from the Staff in Australia’s Schools Survey. Consistent with existing research, our results suggest a relationship between early career teachers with insecure employment and a lack of support. The findings suggest that, for early career teachers, being unsupported is associated with dissatisfaction with professional relationships and career opportunities; and that this dissatisfaction is associated with an intention to leave the profession. 相似文献

OBJECTIVE: The goals of this study were to examine the role of dissociation and depression as possible mediators of the relationship between several forms of childhood trauma and bulimic symptomatology and to explore potential ethnic differences in these relationships. METHOD: Four hundred seventeen female undergraduates participated in this cross-sectional study. They completed measures of dissociative, depressive, and bulimic symptoms, and childhood trauma. Experiences of multiple forms of childhood trauma were measured, including physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect. However, only emotional abuse was correlated with bulimic symptoms at p<.01. Therefore, other forms of trauma were excluded from the analyses to control for Type I error. RESULTS: Dissociation was not associated with emotional abuse after controlling for depression; therefore, tests of dissociation as a mediator were discontinued. Depression was significantly associated with emotional abuse after controlling for dissociation. Emotional abuse was significantly associated with bulimia. Finally, emotional abuse and depression together were significantly associated with bulimia after controlling for dissociation. However, emotional abuse became nonsignificant when entered with depression, indicating that depression mediated the relationship between emotional abuse and bulimic symptoms. There were no ethnic differences in this relationship. CONCLUSIONS: It appears that among women who have experienced childhood emotional abuse, depression is more strongly associated with unhealthy eating behaviors than is dissociation. Results also suggest that emotional abuse is a form of childhood trauma particularly relevant to bulimia. 相似文献

德育学的学科性质问题是德育学领域一个十分重要的本体论问题。根据从教育学的学科性质的探讨和认定所获得的启示以及我国德育学学科建设的现状,德育学既不是一门纯理论的科学理论学科,也不是一门只开具教育处方的经验性学科,而是一门规范性与经验性、科学性与实践性相统一的学科。 相似文献

There tends to be a division in the approaches taken by research into the process of learning to read. Psychometric approaches associated with functional literacy tend to be opposed to more broadly ethnomethodological approaches associated with ‘real books’ and with claims to more emancipatory status. In this article it is argued that this opposition is counterproductive and that we may need both to re‐evaluate the notion of functional literacy itself and to explore with more care the emancipatory claims made for ‘real books’ approaches. It is suggested, further, that a more multivalent approach to reading research is needed that accounts for the variety of literacy practices at home and in school and explores the cultural and ideological contexts of those practices and the values inherent in them 相似文献

BackgroundAdverse childhood experiences are associated with multiple negative behavioral outcomes and childhood sexual abuse (CSA) is particularly damaging. There is controversial evidence that CSA has a specialized effect on subsequent sexual offending.ObjectiveThe current study tested the hypothesis that CSA is associated with sexual offending.MethodUsing a near-population of correctional clients on supervised release in the Midwestern United States, we examined the hypothesis with hierarchical negative binomial regression models.ResultsCSA was significantly associated with official charges for rape/sexual abuse despite controls for sex, race, age, arrest onset, total arrest charges, total adverse childhood experiences, Antisocial Personality Disorder, sexual sadism, and pedophilia. Age of onset of CSA was also inversely associated with sexual offending with effect sizes ranging between 2–5 standardized z-scores.ConclusionThe current study provides significant evidence that CSA is associated with later sexual offending even when accounting for powerful clinical and criminological covariates. 相似文献
