ABSTRACT

In the United States, constitutional and statutory law reinforce the right of all children to receive an education, regardless of their citizenship or immigration status. In a time of heightened anti-immigrant sentiment and law enforcement, however, partnerships among school districts, local law enforcement, and the U.S. Departments of Justice and Homeland Security subject undocumented and unaccompanied minor students to indefensible levels of risk for detention and deportation. We identify three stances that U.S. schools may take in the face of a potential ‘school-to-deportation pipeline.’ Schools that engage in intentional collaboration actively increase detention and deportation by referring students to immigration officials for criminal, non-criminal, and even non-disciplinary activity. Schools that engage in predictable complicity may not intend to subject their undocumented and unaccompanied minor students to detention or deportation, but still put students at risk by involving police in school policies. We argue that U.S. schools should instead engage in proactive protection of immigrant students and families, including actively resisting federal policies when necessary.  相似文献

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the inattentive group in this age range suggest either that inattention results in academic underachievement or that some children in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing (anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence, and other predictors.  相似文献

Despite the large literature concerning the impact of hope and expectancy on various outcomes (e.g., nonvolitional), less is known about the constructs of hope and expectancy themselves. In a recent study, Montgomery et al. (2003) demonstrated that hopes and expectancies are separate but related constructs; however, because both hopes and expectancies were measured within the same context, it is possible that these findings were simply a methodological artifact. Furthermore, it is unknown whether these data would generalize to other populations. Taking into account the importance of this distinction for both the expectancy and hope literatures, the present study sought to: (1) Determine if the distinction between hope and expectancy is a general and reliable phenomenon by using a culturally different sample (i.e., Romanian sample); and (2) Examine the robustness of this distinction by controlling for the context effect. One hundred-twenty five volunteers completed items in regard to 10 nonvolitional outcome scenarios in one of five measurement contexts. The results revealed that hope and expectancy were distinct constructs (p<0.0001), and that this distinction is both general and robust across contexts. Implications for theory and research are discussed.  相似文献

关于高校的实验与实践教学:基于教育心理学理论的思考   总被引:1,自引:0,他引:1  
对于高校教育,运算学习方法多指实验、实践和学生科研活动,学生通过从事的实验、实践和科研活动来实现陈述性知识向程序性知识的转化,学习评价应着重考核学生对知识的理解和运用所学知识去解决问题的能力。本文阐述了突出实验/实践训练的高校教学设计的设想,并强调了应将各种教学实验类型有机地组合,给予学生先进、实用的实验技术的训练,以及在实验/实践教学中运用交互式的教学方法。  相似文献

The National Health Service (NHS) National Genetics Education and Development Centre was established by the Department of Health in 2004 to help drive and co-ordinate genetics education for health professionals working outside specialist genetic services. This paper reviews the experiences and lessons learned to date. At the outset, it was clear that understanding the learning ethos, preferred delivery methods and attitudes towards genetics of different NHS healthcare groups was vital. We collected evidence by undertaking needs assessments with educators, practitioners and patients. We have determined the genetics knowledge, skills and attitudes which they said were needed and translated these into learning outcomes and workforce competences in a continuum of education. Beginning with core concepts introduced (and examined) pre-registration, the continuum continues with development of concepts post-registration as appropriate for role, leading to practical application and assessment of competences in the workplace. These are supported by a portfolio of resources which draw heavily on patient based scenarios to demonstrate to staff that genetics is relevant to their work, and to convince educators and policy makers that genetic education is likely to result in real clinical benefit. A long term educational policy, inclusive of learners, educationalists and their institutions must be evidence based, flexible and responsive to changes in workforce structure, provision of clinical services and conceptual and financial commitments to education. The engagement of national policy, regulatory and professional bodies is vital ().  相似文献

This study set out to examine children’s notions of the malleability of their academic competencies and the relations of these notions to the child’s grade-level and gender and the parent’s educational level. In interviews of a total of 103 boys and girls of the third and the sixth grade, children of academically and vocationally educated parents were asked to rate their potential for improving their competencies in mathematics and Finnish. The children were asked to use intrapersonal and normative criteria in their ratings. The ratings were found to form distinct domains of the notions of malleability, as they did not correlate with each other. The children’s ratings of their current competencies, i.e. their academic self-concepts, turned out to be related to their normative ratings of the malleability of their competencies. The findings further suggested that the children’s notions of the malleability of their academic competencies became more pessimistic in the course of their school years.

In the ordered RNR/RNN serial pattern task, rats often reduce their running speeds on trial 2 less within the RNR than within the RNN series. Initially, investigators (Capaldi, 1985; Capaldi et al., 1983) considered this trial 2 differential speed effect evidence for rats’ anticipation of inter-trial outcomes within each series. Later findings, however, suggest that this effect reflects some generalization of the ordinal position of trial 3 (Burns et al., 1986) or its similar runway cues during trial 2 (Capaldi et al., 1999). To test these generalization hypotheses, we made trial 2 more distinct from trial 3 in each series by forcing rats to alternate runways in a T-maze only on the last trial rather than on trial 2 in each series in Experiment 1, or by forcing rats to alternate runways between trials rather than to run down the same runway on all trials within each series in Experiment 2. Although enhancing the distinctiveness between these trials reduced the trial 2 differential speed effect, extensive training failed to eliminate it. Therefore, this residual difference between trial 2 speeds could reflect rats’ anticipation of trial 3 outcomes during trial 2 as originally proposed by Capaldi (1985) Experiment 3 was designed to determine whether we could enhance rats’ final trial outcome expectancies during trial 2 by making different trial 2 choices distinctive cues for each trial 3 outcome. The trial 2 speed effect was greater when rats were forced to alternate over all trials only within one of the series than when they were sometimes forced to do so in either series. Post-training probe tests revealed that both series position and the relevant within-series runway events contributed to this enhanced anticipation of trial 3 outcomes.  相似文献
