Academic development that supports the enactment of positive psychology practices through student–faculty pedagogical partnership can increase faculty confidence and capacity in their first year in a new institution. When student partners practice affirmation and encouragement of strengths-based growth, processes of faculty acclimation and self-authoring can be accelerated. This article presents a student–faculty pedagogical partnership program and positive psychology practices that focus on faculty strengths and capacities as the foundation for reinforcing and revising existing pedagogical strategies and for sustaining energy for continued development. It combines collaborative autoethnographic and comparative case study approaches to investigate the pedagogical benefits of these practices.  相似文献

The GlobalEd Project employs a technology richenvironment for high school students who wishto participate in a simulation of internationalrelations and negotiation. A simulationconsists of negotiations on a variety ofinternational policy issues conducted bystudents from 10–15 schools through anInternet-based interface. This study reportsthe findings of 234 high school participants'changes in academic and technologyself-efficacy skills, as well as knowledge,attitudes and behaviors related to academicpreparation and performance, the use ofeducational technology, and associated outcomesfrom participating in a simulation ofinternational relations. The results arediscussed in terms of the current literature onself-efficacy and gender differences incognitive process.  相似文献

ABSTRACT

The use of simulated instruction is a growing trend in social work education. This study examined the effectiveness of simulated instruction with undergraduate social work students. In this mixed methods study, the extent to which simulated instruction improved self-efficacy and practice readiness was assessed. Results of the study suggest that simulated instruction helps improve key practice skills and increases recognition of diversity in practice. Moreover, students self-reported increased mastery in interviewing, managing emotions, and engaging in culturally competent practice.  相似文献

Two experiments tested two cynomolgus monkeys’ self-control—choice of a longer, more delayed reinforcer over a shorter, less delayed reinforcer. In Experiment 1, subjects exhibited significant selfcontrol in a procedure in which reinforcer amounts and delays were held constant throughout a condition. In Experiment 2, subjects exhibited significantly greater sensitivity to variation in reinforcer amount than to variation in reinforcer delay in a procedure in which the reinforcer delay associated with the self-control alternative was adjusted until each macaque was indifferent between the two alternatives. Both experiments indicated that, in laboratory paradigms in which humans show self-control and pigeons and rats show impulsiveness, macaques show self-control. These results are inconsistent with the hypothesis that species differences in self-control are a function of language ability or of specific types of prior training. The results are consistent with the hypothesis that species differences in self-control are related to the ratio of brain size to body weight (a possible indicator of general cognitive ability) or to shared phylogeny.  相似文献

Zalocusky et al. (Nature 531:642–646, 2016) recently showed that activity in D2R+ cells in the nucleus accumbens is associated with loss sensitivity to prior outcomes and reduced subsequent risky choice, and that optogenetic stimulation of these cells decreased risky choices in risk-prone rats. While their findings are important for understanding trait-level risk-taking, future research should aim to examine the neuronal mechanisms of a broader range of facets of gain and loss processing with respect to different potential reference points.  相似文献

Following a baseline observation period, a class of intellectually handicapped boys were given opportunities to monitor and record their own behaviour as on‐task or off‐task. Following this self‐monitoring phase, the self‐administered check‐marks were used as tokens and exchanged for back‐up consequences, which were initially low‐value objects for consumption (possession). These were later increased in value, and finally changed to access consequences (the opportunity to play with but not possess). Self‐monitoring alone produced a significant increment in the externally assessed level of on‐task behaviour. Only when access back‐up consequences were introduced was there a further significant increment. Provision of high‐value consumption consequences was followed by a loss of accuracy in self‐monitoring, and reduction in on‐task behaviour to baseline levels. The study demonstrated the extension of a self‐control procedure to retardates, the importance of separately measuring the effect of self‐monitoring on the target behaviour, and the need for appropriate selection of back‐up consequences.  相似文献

Despite growing momentum to overhaul teacher evaluation policies and practices, scant research examines how educators at the street level of such reform—principals and teachers—make sense of them, and almost no research examines the implications of current evaluation reforms for equity. This article provides findings based on a study of 14 districts implementing a new teacher evaluation policy in Connecticut. It focuses on how principals shaped teachers’ opportunities to learn about the new policy. We find that the majority of teachers’ opportunities to learn were formal and in whole group or one-on-one formats. We find important differences in the quantity and quality of learning opportunities at the district level, with districts serving greater shares of low-income students, students of color, and English language learners generally offering teachers fewer and lower quality opportunities to learn about the new reform than their counterparts. As such, this article builds on prior research illustrating the potential of new evaluation systems to exacerbate inequities and raises important cautions regarding the extent to which the unprecedented teacher evaluation reforms (currently underway) may exacerbate inequities among school districts.  相似文献

The greater the dissimilarity between exteroceptive stimuli, the easier it is to discriminate between them. To determine whether a similar relationship holds for memories produced by reward events, rats in three runway investigations received trials in pairs, the number of food pellets (0.045 g) occurring on Trial 1 indicating whether reward or nonreward would occur on Trial 2. In each investigation, discriminative responding on Trial 2 was better the larger the difference in reward magnitude on Trial 1. This finding was obtained under a wide variety of conditions: for example, when the larger of two reward magnitudes on Trial 1 signaled nonreward on Trial 2 (Experiment 1, 10 vs. 2 pellets); when the smaller of two reward magnitudes on Trial 1 signaled nonreward on Trial 2 (Experiment 2, 10 vs. 2 pellets); and when the same magnitude of reward on Trial 1 signaled nonreward on Trial 2 (Experiment 3, either 5 pellets or 0 pellets). The findings obtained here indicate that the greater the dissimilarity between reward magnitudes, the greater the dissimilarity between the memories they produced and, thus, the easier it is to discriminate between them. It is suggested that the present results may provide a basis for understanding findings obtained in other instrumental learning investigations in which reward magnitude is varied.  相似文献
