We estimate the impact of increases in Federal student aid and higher education funding, such as the recently proposed American Graduation Initiative (AGI), on the outcomes of community colleges, including enrollments, list and average tuitions, and educational quality. We develop a reduced form model of state-level education policy in which state policy makers, who have objectives that differ from those of Federal policy makers, respond to changes in Federal policies. Our empirical specification treats state and institutional variables as endogenous; we interpret the coefficients as measuring the responses of state and institution officials to changes in Federal policies. We simulate the effects of AGI and find little evidence that states recapture Federal education resources. AGI would have a significant effect on educational quality but a limited effect on enrollments. An equivalent increase in Federal student aid would have greater impact on access and enrollments, but decrease educational quality.  相似文献

Can young children, forming expectations about the social world, capture differences among people without falling into the pitfalls of categorization? Categorization often leads to exaggerating differences between groups and minimizing differences within groups, resulting in stereotyping. Six studies with 4‐year‐old children (N = 214) characterized schematic faces or photographs as falling along a continuum (really mean to really nice) or divided into categories (mean vs. nice). Using materials that children naturally group into categories (Study 3), the continuum framing prevented the signature pattern of categorization for similarity judgments (Study 1), inferences about behavior and deservingness (Studies 2 and 5), personal liking and play preferences (Study 4), and stable and internal attributions for behavior (Study 6). When children recognize people as members of continua, they may avoid stereotypes.  相似文献

Educational research suggests that lower-income children exhibit poor general executive functioning relative to their higher-income peers. Meanwhile, sports psychology research suggests that an acute bout of aerobic exercise improves executive functioning in children. Yet, it has never been determined if such exercise (1) specifically improves the selective attention aspect of executive functioning in children or (2) impacts lower-income children any differently than higher-income children. The current study utilised a randomised experimental design and found that a 12?min session of aerobic exercise improved the selective attention of both lower- and higher-income children. Moreover, lower-income children exhibited even greater improvement than higher-income children. As the income-achievement gap persists, it is important to explore feasible interventions that strengthen the cognitive processes that underlie academic performance.  相似文献

Many social interactions between school‐age children contain both competitive and cooperative elements. In order to gain a better understanding of how students at risk for emotional and behavioural difficulties (EBD) negotiate social exchanges in cooperative and competitive‐related tasks in comparison with non‐EBD students: (a) prosocial; (b) negative; and (c) conflict behaviours were assessed. Fifty‐seven children at risk for EBD and 57 comparison children participated in three different social tasks with non‐target partners. Both students and teachers completed a standardised behaviour checklist. Social ability and sex differences were considered. Results are discussed from a social‐cognitive framework, and practical implications will be highlighted.  相似文献

A relatively small number of researchers have found it interesting and useful to examine why and how persons choose to be and become adventure educators (AEs) and why they teach as they do. The implications of this knowledge are: (1) gaining insight into novice AEs' perceptions of what is required to provide in-depth and high quality instruction in adventure education; and hence, (2) the impact on the structure of AE training. The purpose of this study was to examine the influence of occupational socialization on two AEs with less than five years' experience. Data were collected using a variety of qualitative techniques while the AEs worked at two, week-long summer camps for elementary and middle school-aged children. They were analysed using standard interpretive methods. Results indicated that both AEs' acculturation led to them entering formal training without having had any structured teaching of adventure content modelled for them, suggesting, as has been found in physical education under similar circumstances, a ‘play only’ perception of the professional field of adventure education with class management and safety, rather than instruction, being the top priorities. Their professional socialization, however, led to real and deep growth and development in their pedagogies. The AEs' organizational socialization, unfortunately served to partially wash out these gains. Key socializing agents at the various stages of the AEs' development are identified and discussed as are practical implications for AE education.  相似文献

In three experiments, we examined whether overshadowing of geometric cues by a discrete landmark (beacon) is due to the relative saliences of the cues. Using a virtual water maze task, human participants were required to locate a platform marked by a beacon in a distinctively shaped pool. In Experiment 1, the beacon overshadowed geometric cues in a trapezium, but not in an isosceles triangle. The longer escape latencies during acquisition in the trapezium control group with no beacon suggest that the geometric cues in the trapezium were less salient than those in the triangle. In Experiment 2, we evaluated whether generalization decrement, caused by the removal of the beacon at test, could account for overshadowing. An additional beacon was placed in an alternative corner. For the control groups, the beacons were identical; for the overshadow groups, they were visually unique. Overshadowing was again found in the trapezium. In Experiment 3, we tested whether the absence of overshadowing in the triangle was due to the geometric cues being more salient than the beacon. Following training, the beacon was relocated to a different corner. Participants approached the beacon rather than the trained platform corner, suggesting that the beacon was more salient. These results suggest that associative processes do not fully explain cue competition in the spatial domain.  相似文献

Two field experiments were performed assessing the effectiveness of the dump-and-chase, a compliance-gaining technique employing strategic persistence. These two experiments demonstrate the effectiveness of the dump-and-chase relative to other known compliance-gaining techniques. Experiment 1 found the dump-and-chase more effective than pooled data from the door-in-the-face and placebic information technique. Experiment 2 found the dump-and-chase more effective than the door-in-the-face, placebic information, and foot-in-the-door. The dump-and-chase produced consistently higher compliance-gaining proportions across experiments. Moreover, because the contextual features of two experiments differed substantially, the effect was robust to important contextual differences.  相似文献

Personal narratives can be powerful venues for understanding human experiences. In this paper, we tell the story of Lutanyani, a Black South African multilingual teacher and author of supplemental reading materials in a marginalized South African language. Through various word images, we convey the role of language, in particular written language, in Lutanyani’s life. For Lutanyani, writing serves as ‘a healing process’ in two ways: (1) as a linguistically empowering venue that affirms and shifts his linguistic identity from outsider to insider, and (2) as a backward‐ and forward‐looking means to reconcile his past and reconstruct a message of hope for intermediate‐grade students throughout South Africa. This study has implications for classroom practices in the USA as well as development work in international settings.  相似文献
