An assessment was undertaken of the attitudes of individuals within the science community towards a program to produce genetically modified cattle for altered milk composition, expectantly allowing for research into the treatment of multiple sclerosis in humans. The majority of respondents to an electronic survey expressed favorable attitudes to the program, thought it beneficial, respected individual freedom and was fair and just and disagreed that it was harmful. A passion for science and having a suitable lifestyle were the most important motivating factors for individuals. Finally, there were a wide range of responses to a number of cultural beliefs or myths. Science grouping significantly affected the responses. Compared with Systems and Land groups, Plant and Reproduction groups more strongly agreed with the project, thought it less harmful to interest groups, felt that genetic modification of animals was more morally acceptable, and more strongly agreed with the myth statements. These results indicate a diversity of beliefs and attitudes towards genetic modification amongst those within the science community, and highlight the importance of understanding ethics and myths in dealing with them. It is suggested that the diversity of beliefs could be better used to help shape public policy and understanding of biotechnology.  相似文献

对四川省极重灾区中小学教师教学效能感现况的调查显示:灾区教师教学效能感处于中等偏上水平,教师个人教学效能感更好,办学条件改善对此起了积极作用,但一般效能感仍需提升;职称、办学类型、学校所在地对教师教学效能感有显著影响;学校办学条件、工作所提供的发展机会以及管理制度对教师教学效能感有显著影响。建议政府对灾区尤其是农村地区教师编制应有所倾斜,增加职称名额,提供多种激励方式;学校应不断完善管理制度,关注教师心理健康,改善教师生存状态。  相似文献

The global environmental crisis intensifies particularly in developing nations. Environmental educators have begun to understand that changing the environmental impact requires not only changes in pro-environmental knowledge and attitudes but also in associated, self-determined motivation. This study was designed to test the hypothesis that a green chemistry curriculum changes Malaysian pre-service teachers?? environmental motivation. Two comparable groups of pre-service teachers participated in this study. The students in the experimental group (N?=?140) did green chemistry experiments whereas the control group (N?=?123) did equivalent experiments in a traditional manner. Posttest results indicate that there is significant difference between both the groups for intrinsic motivation, integration, identification, and introjections scales and no differences for external regulation and amotivation scales. The qualitative analysis of interview data suggests that the changes are predominantly due to the personal satisfaction that participants derived from engaging in pro-environmental behavior.  相似文献

Intuition presents as a crucial component of professional competence for many occupations, including emergency physicians because many of their decisions have to be made quickly. When arriving at the scene of an accident, they promptly have to assess the circumstances and initiate immediate life-saving measures without opportunities for deep analyses of patients’ conditions. Therefore, spontaneous and intuitive decisions are required to solve the problem appropriately, rather than more intentional and time-consuming forms of decision-making. Yet, the efficacy of and processes underpinning these intuitive activities remain far from fully understood or clearly conceptualised. The study reported here aims at revealing the efficacy of such intuition by analysing decision-making behaviour of emergency physicians. Based on patient simulation mannequins, which can be programmed to present specified clinical situations, three groups of participants with different levels of emergency medicine expertise (n 1  = 10 novices, n 2  = 10 semi-experts, n 3  = 10 experts) each addressed two different authentic problem cases. In the first simulation, time pressure was utilised to press participants to decide intuitively. In the second simulation, the participants had to legitimise their decisions without any time pressure in order to generate rational decisions. Whereas no clear difference in the participants’ performances between both cases could be identified, experts and semi-experts performed better than novices in their intuitive decision-making, thereby supporting beliefs about the efficacy of intuition. It is proposed that medical education, as well as other forms of occupational preparation, should consider theories of mental simulations in order to improve surgeons’ professional education.  相似文献

Elementary mathematics curriculum materials can serve as a lever for instructional change. In this paper, we promote a particular kind of instructional change: supporting teachers in learning to integrate children’s multiple mathematical knowledge bases (MMKB), including children’s mathematical thinking and children’s home and community-based mathematical funds of knowledge, in instruction. A powerful means of supporting pre-service teachers in integrating children’s MMKB in instruction may be to scaffold teachers’ noticing of potential spaces in elementary mathematics curriculum materials for connecting to children’s MMKB and then developing practices for leveraging these spaces during instruction. We focus on existing and potential spaces in written curriculum materials, or curriculum spaces, so as to better support teachers in enacting curriculum that opens spaces for connecting to children’s MMKB.  相似文献

This paper is based on an interview study with eighty science teachers in twelve secondary schools across Australia. The study was conducted as part of the Science Education Professional Development Project. The project's brief was to develop a national strategy for the professional development of science teachers and was commissioned by the Federal Government's Department of Employment, Education and Training. The aim of the interviews was to help define the problem that a national strategy needed to address and this paper reports on one theme that emerged from the interviews, the concept of “loose connections.” Loose connections reflects the weak sense of professional community we found among science teachers and their isolation from potentially beneficial influences on their work. The paper explores implications of loose connections for a national professional development strategy such as the need to strengthen areas of professional responsibility and links between professional development and career development.  相似文献

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.
