On 23 June 2003, the Supreme Court of the United States issued two rulings on the constitutionality of race preferences in university admissions. The cases in question both involved the University of Michigan and were designated Gratz v. Bollinger and Grutter v. Bollinger. Academic Questions' editors subsequently invited five scholars to address the meaning and significance of those decisions. 相似文献

The relations between changes in the scalp-recorded electroencephalogram (EEG) and the development of the ability to perform successfully 2 cognitive tasks attributed to frontal lobe functioning were examined in 13 infants from 7 to 12 months of age. Infants successful in performing the A-not-B task with increasingly longer delays across the second half of the first year of life showed changes in power in scalp-recorded brain electrical activity in the frontal region and an increase in anterior/posterior EEG coherence. Infants with rapid mastery of object retrieval did not differ in frontal EEG development from infants who exhibited the normal developmental progression in object retrieval performance. In a task examining inhibition of reaching to a novel toy, there were no differences in frontal EEG as a function of performance. Results from a cross-sectional sample revealed similar findings. These data confirm work with nonhuman primates on the importance of maturation of frontal cortex in the successful performance on certain tasks (A-not-B), but do not confirm nonhuman primate data on the importance of frontal cortex for other tasks (object retrieval). The data also suggest that the electroencephalogram may be useful as a noninvasive measure of central nervous system development during the first year of life. 相似文献

This paper describes an effort to develop a survey instrument capable of measuring important aspects of adolescents’ experiences of interest-related pursuits that are supported by technology. The measure focuses on youths’ experiences of connected learning (Ito et al. in Connected learning: an agenda for research and design. Digital Media and Learning Research Hub, Irvine, 2013), an emerging model of learning across settings supported by digital media. Specifically, the instrument aims to measure the depth with which youth are able to engage in an interest-related pursuit, the level of support and encouragement they receive from peers, and the degree to which their pursuit involves performance or media production as an essential feature. The survey also elicits information regarding the connections between youths’ interest-related pursuits and academic goals, the involvement of adults as co-participants in pursuits, and youths’ access to technology tools they deem necessary for their pursuits. The paper reports on results from a pilot study and two rounds of field-testing, in which we evaluated the validity and reliability of the instrument and compared results with evidence from interviews with youth. Our aim was to investigate the feasibility of an approach to measuring youths’ interest-related pursuits to inform future research and evaluation of initiatives focused on digital media and learning. 相似文献

AbstractThis article explores how critical conversations engage undergraduate mathematics faculty in a community of practice that enhances their knowledge about teaching and learning mathematics for social justice. More broadly, critical conversations are defined as a cooperative learning strategy that can be used to identify, explore, and respond to various interests and issues situated across differing values and beliefs. We present a case study of a critical conversation that took place at a 2016 Mathematics for Social Justice workshop organized by a group of junior faculty. Participant reflections situate perspectives that can help novice and experienced instructors design conversations about teaching mathematics for social justice. Specifically, individual and group reflections highlight the importance of: (i) framing and reflecting on the conversation; (ii) exploring implications and content connections; and (iii) identifying barriers. Implications for faculty members and mathematics departments are provided. 相似文献

Research has shown an increase in the study and discussion of international counseling throughout the past decade in the mental health domain. The counseling profession continues to take steps to address the lack of access to and the quality of counseling support throughout the world. A Q-sort methodology was utilized in order to capture an understanding of what might be identified as the most important traits for counselors to consider when counseling in international settings. A uniquely constructed Q-sort model developed from a careful review of the literature resulted in 35 items that were evaluated by 43 participants in two phases of analysis. The results from the Q-sort led to fuller consideration of the 12 counseling traits ranked highest. Three core themes that emerged from the data included: valuing people, personal character, and multicultural intentionality. Discussion about the highest ranked traits and core themes provides consideration of research implications and future studies in international counseling as a whole. 相似文献

Data are reported from 3 groups of children residing in Bucharest, Romania. Face recognition in currently institutionalized, previously institutionalized, and never-institutionalized children was assessed at 3 time points: preintervention ( n = 121), 30 months of age ( n = 99), and 42 months of age ( n = 77). Children watched photographs of caregiver and stranger faces while event-related potentials were recorded. Results demonstrate that institutionalized children show pervasive cortical hypoarousal in response to faces and that foster care is somewhat effective in remediating this deficit by 42 months of age. All 3 groups of children distinguished between the familiar and unfamiliar faces. These results have the potential to inform an understanding of the role of early experience in the development of the neural systems that subserve face recognition. 相似文献
