This study examines how third-graders’ conceptions about the origin of species are affected by formal instruction and whether children can learn not only about evolution but also about natural selection. We interviewed the same group of third-grade children (8–9 years old) twice, before and after following a curriculum about these topics. Creationist answers were very rare at both pre- and post-tests. The number of evolutionist answers increased significantly after instruction. However, children learned about evolution in a piecemeal way; they gave evolutionist answers for only some of the animals they were asked about and made several errors when putting classes of vertebrates on a time line. In addition, only a minority of children learned something about evolutionary mechanisms. They said that new-born animals can be different from the parents because of mutations but did not mention differential survival. These results challenge the views, according to which, cognitive biases (i.e. essentialism, teleological and intentional thinking) make children unreceptive to evolution. 相似文献

The actual infrastructure of the information society sustains the globalization trend and increases the importance of the information and knowledge. The development of the knowledge society is the direct consequence of the mix of economic, social and cultural processes, which involve the knowledge creation and its equitable distribution, access and sharing. Universities, as poles of knowledge, creativity and innovation, play a key part in the regional development and the global competitiveness. The universities are active promoters of the innovation culture at the regional and international level, by increasing the synergy among education, research and innovation. The article focuses on the role of the academic area in the development of the learning and creative society at the regional level, contributing to the design of new knowledge and technology embedded products, services and organizational processes, which represent the premises of the global competitiveness. The most important challenge the academic environment faces in the new economy is to bridge the gap between the political decision, the governance and the labour market, offering innovative solutions and developing the intellectual capital to address the various issues of the knowledge economy. The article highlights the role of the universities as regional development drivers, by analyzing the economic performance of the Bucharest-llfov region and the direct influence of the trinomial equation: education-research-innovation. 相似文献

AbstractIn this paper, the role of sport in the processes of creating the modern woman in the interwar Poland will be examined. The analysing of the women’s press shows how the publicists use the hygiene and the woman’s body in discourse of age and in building the new emancipated, strong woman. How they incorporated ideas young body, active lifestyle, and images of modern women – la Garçonne created in USA and West Europe and presented them to the Polish audience. 相似文献

This paper approaches the issue of higher entrepreneurship education in motivating young people to start their own business as a viable alternative to the successful integration of university graduates on the labour market. The fundamental question of this research is if, currently, entrepreneurship education influences students’ entrepreneurial intentions and to what extent. The research results, based on the statistical analysis of data collected through a questionnaire distributed to Romanian business and engineering bachelor students in the final year, highlight that business students assessed the effectiveness of higher entrepreneurship education and its positive influence on entrepreneurial intentions to a greater extent than the engineering students. Furthermore, entrepreneurial intentions of engineering students are influenced positively much more by entrepreneurial family background than by entrepreneurship education. The findings provide important highlights for future research, in order to identify the most effective ways of approaching, modernising and expanding entrepreneurship education, aiming to increase entrepreneurial intentions among students, regardless of the graduated field of study. 相似文献

The purpose of this study was to examine how the practicing science and mathematics teachers participating in the University
of Florida's Teacher Research Update Experience (TRUE) perceived their experiences in Summer 2000. We conducted in-depth interviews
and collected data from survey questionnaires and addressed research in the following areas: How do participants perceive
their experiences during the 7-week program designed to enhance science, mathematics, and technology knowledge and skills?
How have these experiences contributed to their professional and personal growth and development, and how will they influence
teaching and student learning? Findings from interviews provided insights into the thoughts, motivations, and, in some cases,
insecurities of these adult learners. Follow-up studies are indicated on long-term impact of immersion professional development
programs. 相似文献

Objective
Being overweight or obese comprises a significant risk factor for atherosclerosis. Fat tissue also generates factors stimulating angiogenesis, the process by which new blood vessels form. The purpose of this paper is to assess concentrations of the vascular endothelial growth factor A (VEGF-A) and its soluble type-1 and type-2 receptors (sVEGFR-1 and sVEGFR-2) in plasma of patients with peripheral arterial disease (PAD) depending on the level of nutrition according to body mass index (BMI).Methods
The study group included patients suffering from symptomatic PAD (n=46) in Fontaine classes IIa–IV without any history of neoplastic disease and who have a normal BMI (n=15), are overweight (n=21) or are obese (n=10). The control group (n=30) consisted of healthy non-smoking volunteers who were neither overweight nor obese. Venous blood plasma samples were collected from both groups at rest in the morning to determine plasma concentrations of VEGF-A, sVEGFR-1, and sVEGFR-2 using the enzymelinked immunosorbent assay (ELISA) method.Results
The group of patients with PAD co-existent with being overweight or obese tended to have higher mean concentration levels of VEGF-A and sVEGFR-2 when compared with patients suffering from PAD with normal BMI. A statistically significant positive correlation was obtained between BMI and average plasma concentrations of sVEGFR-2 (R=0.37, P=0.0103). However, no significant correlation was noticed between BMI and VEGF-A or sVEGFR-1 concentrations.Conclusions
A positive correlation determined between the level of antiangiogenic factor and BMI value may be indicative of the linearly growing prevalence of some antiangiogenic factors in patients with metabolic disorders, which may be one of numerous factors contributing to incomplete efficiency of collateral circulation development in patients with PAD.28.

Objective
This study was aimed at assessing the dynamics of vitronectin (VN), laminin (LN), and heparan sulfate/heparin (HS/HP) content changes during experimental burn healing.Methods
VN, LN, and HS/HP were isolated and purified from normal and injured skin of domestic pigs, on the 3rd, 5th, 10th, 15th, and 21st days following thermal damage. The wounds were treated with apitherapeutic agent (propolis), silver sulfadiazine (SSD), physiological salt solution, and propolis vehicle. VN and LN were quantified using an immunoenzymatic assay and HS/HP was estimated by densitometric analysis.Results
Propolis treatment stimulated significant increases in VN, LN, and HS/HP contents during the initial phase of study, followed by a reduction in the estimated extracellular matrix molecules. Similar patterns, although less extreme, were observed after treatment with SSD.Conclusions
The beneficial effects of propolis on experimental wounds make it a potential apitherapeutic agent in topical burn management. 相似文献29.
Peer review of teaching is a collegial process designed to help academics reflect on and improve their teaching practice. Considerable research supports the value of peer review of teaching. However, uptake of voluntary programs is typically low. Few studies have examined the predictors of engagement in voluntary peer review. This study surveyed 221 (106 female, 115 male) academics in the first year of implementation of a peer review of a teaching program at a large dual-sector university. Results supported the impact of four key variables on willingness to engage in peer review of teaching: the perceived benefits of the program, an individual's perceived need for support around teaching, perceived drawbacks of the program and career-related benefits. Level of teaching experience was related to willingness to engage: staff with moderate levels of teaching experience were most willing to participate in the program. Limitations of the study are noted and recommendations for peer-review programs are provided. 相似文献

ABSTRACTOver a period of three years this longitudinal study explored new approaches to consider student identity during the transition from university to employment. Students were followed through a new portfolio-based final year course and beyond university into the workplace. With universities increasingly recognising the employment aspirations of their students, facilitating self-awareness of graduate attributes and the development of employability skills are becoming integral to the higher education proposition; however the impact of employability initiatives is not well understood. The aim of the study was to examine changes in self-identification through the development of a portfolio of work using Holmes’ Claim Affirmation Model of Emergent Identity as the conceptual framework. Data were collected through student questionnaires and graduate interviews. The study uncovered the ways in which role models, developmental networks, and imaginings of a possible self were used in identity work. A fragile reconstruction of identity was observed as graduates faced the labour market, with this fragility continuing to be experienced while navigating an uncertain work landscape. We used these findings to allow us to refine Holmes’ Model by (a) adding a dynamic element and (b) grounding it on longitudinal data. 相似文献
