Efforts to eliminate or neutralize the coverage of evolution in high school biology textbooks in the United States have persisted with varying degrees of intensity and success since the 1920s. In particular, the coverage of human evolution has been impacted by these efforts. Evidence of the success of these efforts can be chronicled by the emphasis given to human evolution in secondary biology textbooks historically and in the current state science standards. Prior to the 1960s, biology textbooks provided little emphasis to human evolution. In the 1970s and early 1980s textbooks reduced the coverage of human evolution. However, in the 1990s the coverage became quite comprehensive again. In 2004, the state science frameworks of only three states had standards concerned with human evolution.  相似文献

The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. We look at innovative firms in the period from 2000 to 2002 taken from the Mannheim Innovation Panel and estimate the effect of collaborative measures of knowledge management on the immediate economic success of different types of innovations. The results of our matching analysis reveal that firms which apply knowledge management perform better in terms of higher-than-average shares of turnover with innovative products compared to their twins. We do not find a significant effect of knowledge management on the share of cost reductions with process innovation.  相似文献

Group‐based social hierarchies exist in nearly every society, yet little is known about whether children understand that they exist. The present studies investigated whether 3‐ to 10‐year‐old children (N = 84) in South Africa associate higher status racial groups with higher levels of wealth, one indicator of social status. Children matched higher value belongings with White people more often than with multiracial or Black people and with multiracial people more often than with Black people, thus showing sensitivity to the de facto racial hierarchy in their society. There were no age‐related changes in children’s tendency to associate racial groups with wealth differences. The implications of these results are discussed in light of the general tendency for people to legitimize and perpetuate the status quo.  相似文献

In this article, the author explores the richly layered double text of Kushner and Sendak’s picturebook, Brundibar (2003)—the historical context of Brundibár as a Holocaust-era children’s operetta by Hans Krása and Adolf Hoffmeister, and the present day manifestation of Brundibar as a children’s picturebook. In order to contextualize the discussion of Kushner and Sendak’s text, Brundibar’s historical origins in Nazi-annexed Czechoslovakia and its transition to the stage in the Nazi “model” concentration camp, Terezín, is presented. An extensive semiotic analysis of Kushner and Sendak’s illustrations and text is also provided within the framework of what Kushner (The art of Maurice Sendak: 1980 to the present, 2003) terms “a world of trouble and woe and worse” (p. 210). Furthermore, the author discusses the development of Sendak’s Hitlerian Brundibar and the struggles that both Kushner and Sendak faced as they considered how to portray the story’s antagonist, given their somewhat differing conceptions of which difficult themes and topics children should be exposed to during childhood. To round out this discussion, the author explores pedagogical implications for teachers as they read difficult texts, particularly Holocaust texts, with children.  相似文献

This paper examines how a team of teachers in a Norwegian upper secondary school responds to, negotiates, and evaluates students' writing in and across different disciplines. The purpose is to identify discourse strategies and professional development as the teachers discuss students' texts, and to explore how the teachers develop a shared understanding of how writing relates to students' learning. The findings show how the teachers' discourse reflects an emerging understanding of how writing is both a subject-specific and interdisciplinary skill conducive to learning, but also how institutional traditions and discipline-specific concerns together allow for and constrain teachers' learning.  相似文献

Abstract

We assess the long-term effectiveness of outreach and education efforts associated with a water quality improvement project in a watershed located in northern Utah, USA. Conducted 15 years after the original project began, our research examines the lasting impacts of different extension activities on landowners’ motivations to participate and their awareness and understanding of the water quality problem. Data were gathered by reviewing annual project reports, interviewing project staff about outreach and education efforts, and conducting in-depth, semi-structured interviews with a majority of the farmers and ranchers who participated in the project. The findings suggest that landowners were motivated to participate in the programme more by practical farm and household considerations and available cost-share opportunities than by particular environmental concerns. Previous relationships between farmers and government programme staff and one-on-one visits with landowners played an important role in their decisions to participate, while demonstration projects and peer-to-peer social diffusion processes played a much smaller role than expected. Although participants had a good grasp of the project goals, they did not have a strong sense of ownership of the water quality problem. These results suggest that education and outreach approaches centred only on the environmental dimensions of conservation projects may be insufficient to motivate changes in conservation behaviour. The results also suggest that conventional outreach strategies often did not have their presumed impact on landowners.  相似文献

ABSTRACT

Libraries are responsible for the safety, security, and welfare of their patrons, employees, collections, buildings, and property. Well-designed library spaces enhance the overall security and safety of the library building and its users. One potential tool to assist in assessing library spaces and building design is the Crime Prevention through Environmental Design (CPTED) methodology. This article presents a case study in which a CPTED checklist was used to examine safety and security design features in an academic library environment. In conjunction with other safety measures, including dedicated safety committees, expert-led safety trainings, and ongoing conversations about security in the library, the CPTED checklist can help inform library conversations about building security and contribute to a safer, more secure atmosphere in which students can thrive.  相似文献
