Research Findings: An emerging consensus is that casual, direct contact with nature influences the development of children’s biological knowledge. Here we review the existing literature on this topic, focusing on the effects of (a) rural versus urban rearing environments and (b) pet ownership and care on children’s biological concepts and reasoning. Although the research is limited, the evidence suggests that these factors positively influence children’s understanding of specific biological phenomena (e.g., internal organ function, biological inheritance) and reasoning patterns (e.g., anthropocentrism, ecological reasoning). Practice or Policy: In the modern context of diminishing outdoor playtime and limited experience with nature, this review highlights the importance of direct exposure to the natural world for children’s conceptual development in the domain of biology. 相似文献

OBJECTIVES: This study had two primary objectives: First, to examine the nature and co-occurrence of various forms of child maltreatment (sexual, physical, emotional, and witnessing violence) reported by Latina college students, and second, to explore coexisting maltreatment types and acculturation status as possible contributors to long-term adjustment difficulties. METHOD: Participants were 112 Latina undergraduate students categorized by the number of childhood maltreatment types experienced (0, 1, or 2 or more) and acculturation level (1 to 5). The possible effects of co-occurring forms of maltreatment, in conjunction with acculturation status, were investigated with respect to participants' reported trauma symptomatology. Data were collected using self-report measures. RESULTS: Nearly three out of 10 participants (29%) experienced more than one type of child maltreatment and, as expected, these individuals reported greater trauma symptomatology than those reporting either a single type of maltreatment or no maltreatment at all. Those who reported multiple types also endured more severe maltreatment than did respondents who experienced a single type. Acculturation level was neither directly related to trauma symptoms nor did it moderate the lasting correlates of maltreatment among victims. Interestingly, those who experienced a single form of maltreatment reported no more trauma symptoms than did participants who reported no maltreatment history at all. CONCLUSION: This investigation documents a large degree of overlap among various forms of self-reported childhood maltreatment within a Latina college population. The results underscore the need to consider multiple forms of maltreatment, as well as severity, when making inferences regarding potential effects on later functioning. 相似文献

Netcourses—courses delivered primarily over digital networks—promise to provide learners with quality, low-cost learning opportunities anywhere and anytime. While having implications throughout education, adult professionals may be the first to make extensive use of netcourses. By increasing the quality and timeliness of teacher professional development while reducing its costs, netcourses could have a major impact on the quality of teaching. In order to understand the realities of this promise, we have reviewed in detail all netcourses for teachers in mathematics and science. As a result of this analysis, we have developed new designs for the effective use of this medium with mathematics and science teachers. 相似文献

Understanding what teachers need to be more comfortable and confident in their profession is crucial to the future of effective teachers and scientific literacy in public schools. This study focuses on the experiences of Arizona biology teachers in teaching evolution, using a clinical model of stress to identify sources of pressure, the resulting stresses, and coping strategies they employ to alleviate these stresses. We conducted focus groups, one‐on‐one interviews, and written surveys with 15 biology teachers from the Phoenix area. On the basis of their responses, teachers were clustered into three categories: “Conflicted,” who struggle with their own beliefs and the possible impact of their teaching, “Selective,” who carefully avoid difficult topics and situations, and “Scientists,” who see no place for controversial social issues in their science classroom. Teachers from each group felt that they could be more effective in teaching evolution if they possessed the most up‐to‐date information about evolution and genomics, a safe space in which to reflect on the possible social and personal implications with their peers, and access to richer lesson plans for teaching evolution that include not only science but personal stories regarding how the lessons arose, and what problems and opportunities they created. © 2004 Wiley Periodicals, Inc.

ABSTRACT Clark and Murray examine the six Critical Performance Factors for Mega planning in an example drawn from the five‐year history of the population program of a major west coast philanthropy. In this article, the authors describe the salience and scope of the population issue as it is relates to other global trends; the steps the foundation took to “scope” the program and establish measurable impacts. It rates performance against the critical factors, then looks at some specific country impacts five years later. This analysis will be incorporated into the plan revision. Summary and What Next Indications are that our funding and the work of the grantees are having good impact in the country programs. Systematic, comprehensive reviews involving outside/inside experts, quantitative and qualitative data will be completed in all five country programs by mid‐2005. Also in 2005, the Board will work with staff and outside experts to examine the results of grant making and review and discuss our long term, overall approach. Much has changed since 1998. We will review those changes and see if any longer term shifts in funding emphasis will be appropriate. This effort to refresh our strategic thinking will allow us to revise, as appropriate, the stated missions of the population work, its assumptions, and how it fits into the overall work and goals of the Foundation. 相似文献

We apply the comparative techniques originated by Wolpin, K.I. (1977, Education and screening, American Economic Review, 67, 949–958) and Psacharopoulos (1979, On the weak versus the strong version of the screening hypothesis, Economics Letters, 4, 181–185) to discriminate between the ‘weak' and ‘strong' screening hypotheses. Controlling for sample selection, we find evidence for weak but not strong screening in the Italian labour market. [JEL J3, J24, J41] 相似文献

This paper explores the issues and concems identified by a small group of teachers implementing technology ideas using the
national document,A Statement on Technology for Australian Schools (Curriculum Corporation, 1994a), represented in four key questions they posed as a result of reflection upon their existing
ideas and practices, early in the study. These same issues and concerns framed their later experiences as the study progressed.
The case study of one of the teachers is used, to illustrate how the teachers implemented technology education working from
their own perspectives and tackling issues and concerns that made sense to them. By reviewing the teachers' own questions
about technology implementation, it is becoming, clear that what may be important for professional development in technology
education is related to the questions that the teachers themselves are asking about their own, beliefs and practices. 相似文献

This study explored whether children's (N = 158; 4- to 9 years old) nonverbal facial expressions can be used to identify when children are being deceptive. Using a computer vision program to automatically decode children's facial expressions according to the Facial Action Coding System, this study employed machine learning to determine whether facial expressions can be used to discriminate between children who concealed breaking a toy(liars) and those who did not break a toy(nonliars). Results found that, regardless of age or history of maltreatment, children's facial expressions could accurately (73%) be distinguished between liars and nonliars. Two emotions, surprise and fear, were more strongly expressed by liars than nonliars. These findings provide evidence to support the use of automatically coded facial expressions to detect children's deception. 相似文献

The Standards Committee of the Veterinary Medical Libraries Section was appointed in May 2000 and charged to create standards for the ideal academic veterinary medical library, written from the perspective of veterinary medical librarians. The resulting Standards for the Academic Veterinary Medical Library were approved by members of the Veterinary Medical Libraries Section during MLA '03 in San Diego, California. The standards were approved by Section Council in April 2005 and received final approval from the Board of Directors of the Medical Library Association during MLA '04 in Washington, DC. 相似文献
