Abstract Drawing from an array of theoretical and experiential sources ranging from policy studies to ethnographies, this essay frames a number of public policy issues related to children, families, and early childhood education. These issues provide a brief genealogy of multiple contexts in which early childhood teacher education operates in the United States. Issues addressed include: welfare reform, “No Child Left Behind” legislation, the crimi‐nalization of children, language policies, and recently proposed changes in Head Start. The author draws from her teaching, research, and community organizing experiences to recommend ways to strengthen public policy awareness and advocacy engagement in the field of early childhood teacher education. 相似文献

Abstract A major challenge for teacher preparation programs and future teachers is learning to work skillfully with the diversity of children in American classrooms. This paper describes a tool developed to address this challenge: the Learning and Teaching Assessment System (LTAS). The LTAS is a performance‐based, curriculum‐embedded assessment tool designed to uncover young children's strengths in different curricular areas as well as their approaches to learning. Developed for use with children 3–8 years of age, the LTAS helps teachers understand what children know in relation to key concepts in the different disciplines as well as how they learn in order to further their learning in subsequent days and weeks of teaching. The development of the LTAS is based primarily on two theoretical frameworks: Leont'ev's activity theory and Gardner's theory of multiple intelligences. To examine the efficacy of the LTAS in its proposed objectives, a pilot study was conducted; results point to the potential of the LTAS for helping student teachers uncover new information about children to guide future instruction. 相似文献

The political, military and media rhetoric of the March–April 2003 invasion of Iraq is interpreted as a phenomenon of power in relation to an understanding of culture as a site of denegation. Patterns of tautology, euphemism and equivocation are identified and their rhetorical appeal analysed in terms of the denegational structure of each of these figures. The essay is thus governed by an understanding of figuration as instrumental, not ornamental; it shows how rhetoric can be studied as a cultural phenomenon and argues by example that a pragmatics of troping is crucial to such a study. 相似文献

Physician opinions about an anatomy core curriculum: A case for medical imaging and vertical integration 下载免费PDF全文
Courtney P. Orsbon Rebecca S. Kaiser Callum F. Ross 《Anatomical sciences education》2014,7(4):251-261
Pre‐clinical anatomy curricula must provide medical students with the knowledge needed in a variety of medical and surgical specialties. But do physicians within specialties agree about what anatomical knowledge is most important in their practices? And, what is the common core of anatomical knowledge deemed essential by physicians in different specialties? Answers to these questions would be useful in designing pre‐clinical anatomy courses. The primary aim of this study was to assess the importance of a human gross anatomy course by soliciting the opinions of physicians from a range of specialties. We surveyed 93 physicians to determine the importance of specific anatomical topics in their own practices. Their responses were analyzed to assess variation in intra‐ and inter‐departmental attitudes toward the importance of anatomy. Nearly all of the topics taught in the course were deemed important by the clinicians as a group, but respondents showed little agreement on the rank order of importance of anatomical topics. Overall, only medical imaging received high importance by nearly all respondents, and lower importance was attached to embryology and lymphatic anatomy. Our survey data, however, also suggested distinct hierarchies in the importance assigned to anatomical topics within specialties. Given that physicians view the importance of anatomy differently, we suggest that students revisit anatomy through a vertically integrated curriculum tailored to provide specialty‐specific anatomical training to advanced students based on their areas of clinical interest. Integration of medical imaging into pre‐clinical anatomy courses, already underway in many medical schools, is of high clinical relevance.

Although historical changes in scientific ideas sometimes display striking similarities with students’ conceptual progressions, some scholars have cautioned that such similarities lack meaningful commonalities. In the history of evolution, while Darwin and his contemporaries often used natural selection to explain evolutionary trait gain or increase, they struggled to use it to convincingly account for cases of trait loss or decrease. This study examines Darwin’s evolutionary writings about trait gain and loss in the Origin of Species (On the origin of species by means of natural selection, or the preservation of favoured races in the struggle for life. D. Appleton, New York, 1859) and compares them to written evolutionary explanations for trait gain and loss in a large (n > 500), cross-cultural and cross-sectional sample (novices and experts from the USA and Korea). Findings indicate that significantly more students and experts applied natural selection to cases of trait gain, but like Darwin and his contemporaries, they more often applied ‘use and disuse’ and ‘inheritance of acquired characteristics’ to episodes of trait loss. Although the parallelism between Darwin’s difficulties and students’ struggles with trait loss are striking, significant differences also characterize explanatory model structure. Overall, however, students and scientists struggles to explain trait loss—which is a very common phenomenon in the history of life—appear to transcend time, place, and level of biological expertise. The significance of these findings for evolution education are discussed; in particular, the situated nature of biological reasoning, and the important role that the history of science can play in understanding cognitive constraints on science learning. 相似文献

Atypical motor behaviors are common among children with autism spectrum disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among 6‐month‐olds at increased risk (high risk) for ASD (N1 = 129; N2 = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high‐risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free‐play) context than infants with no family history of ASD. Longitudinal assessments suggest that between 6 and 10 months, grasping activity increases in high‐risk infants. 相似文献

Universities aim to provide services that are not only beneficial to students but also efficient relative to possible alternative services. Using opportunity cost, this study considers staff and student perceptions of the usefulness and valuation of web-based lecture technology (WBLT). It reveals that a quarter of students did not use WBLT while many staff members thought WBLT had a negative impact on their face-to-face teaching. Further, over a third of students sampled said they would not be affected if WBLT were not made available and many staff members felt constrained by WBLT technology. Some staff members spent a lot of time preparing WBLT while others eschewed the technology altogether. Nevertheless, a relatively small number of students place enormous value on WBLT, as do some staff, even if only simple audio of lectures are provided. The academic policy implications of this study suggest that university provision of WBLT could take into account the opportunity cost of WBLT use as a valuation-basis, possibly recovering costs through extra fees. This would allow for improved decision-making by university administrators and facilitate a move towards a useful measurement basis of WBLT. A wider academic policy implication is to consider whether all universities should produce and deliver WBLT at all and to what extent it should encourage staff to develop enhanced WBLT. Provision of sophisticated WBLT or any other service for students bears an opportunity cost in terms of less preparation by staff for face-to-face lessons or other effective teaching or research. 相似文献

This study quantifies racial/ethnic differences in Medicaid expenditures on psychotropic drugs among a national sample of children with suspected maltreatment. We linked 4,445 child participants in the National Survey of Child and Adolescent Well-Being (NSCAW) – consisting of children investigated for suspected abuse and neglect – to their Medicaid claims obtained from 36 states. We used propensity score matching to construct a comparison group of children without known child welfare involvement, and estimated two-part generalized linear models to examine differences in annual psychotropic drug expenditures per child between children of different races/ethnicities. When compared to a matched sample of children, African American and Latino children incur $292 and $144 less expenditures on psychotropic drugs, respectively, than white children. Among NSCAW children alone, African American children display $614 less spending on psychotropic drugs when compared to white children. Racial/ethnic differences in expenditures on psychotropic drugs occur among all children on Medicaid, but the differences are especially pronounced among African American children in contact with the child welfare system. These findings demonstrate that policymakers will need to pay special attention to the needs of children of color as Medicaid expansions proceed nationwide. 相似文献
