隐喻在教学和教师教育中的功能

隐喻的本质是用一种事物来理解和经历另一种事物.基于对教学与其他事物相似性的认识和理解,隐喻在教学和教师教育中可以发挥反映教师专业思想,作为教师教学的策略,作为评价、研究和发现的工具,作为教师反思的中介和教学思想转变的"跳板"等十个方面的功能.     

Relationship between serum interleukin-1beta levels and acute phase response proteins in patients with familial Mediterranean fever

Introduction:

The aim of this study was to investigate whether serum levels of interleukin-1β (IL–1β) has any possible correlation on inflammatory parameters such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and fibrinogen concentration in patients with familial Mediterranean fever (FMF) patients during attack-free period.

Materials and methods:

The serum levels of IL-1β, as an indicator of cytokines status, and the acute phase response proteins, CRP, ESR and fibrinogen levels were evaluated in 35 attack-free patients with FMF and 25 healthy volunteers.

Results:

Serum IL-1β levels were significantly higher in patients with FMF than control subjects (P = 0.018). There was no statistically significant difference in the serum levels of ESR, CRP and fibrinogen between two groups (P = 0.181, P = 0.816, P = 0.686, respectively). There was a significant correlation between IL-1β and CRP (r = 0.513, P = 0.002) values of FMF group.

Conclusions:

In conclusion, our results confirm the presence of increased IL-1β levels in FMF patients during attack-free period. Serum IL-1β values seems to correlate with CRP levels. The elevation of IL-1β levels may be important in monitoring subclinical inflammation of attack free period in FMF patients.     

Determination and Evaluation of the Science Teacher Candidates’ Misconceptions About Density by Using Four-Tier Diagnostic Test

This study has two aims. The first one is to reveal the science teacher candidates’ misconceptions about the density by using a four-tier diagnostic test, and the second one is to determine to what extent science teacher candidates have scientific knowledge, lack of knowledge, and misconceptions about the density. In order to achieve these aims, a four-tier density diagnostic test was developed with the KR-20 reliability coefficient of 0.753 based on the correct answers, and the KR-20 reliability coefficient of 0.528 based on the misconceptions. To determine the misconceptions about the density with the developed test, data were collected from a total of 470 science teacher candidates from seven different universities in Turkey. With the developed four-tier diagnostic test, 48 different misconceptions were revealed. The results of the research showed that about one fourth of science teacher candidates had a misconception about the density and that the ratio of six of the resulting misconceptions was over 10%. It may be suggested that this study conducted on science teacher candidates should also be conducted on middle and high school students and experimental studies should be carried out to eliminate the misconceptions that emerged in this study.

     

Development and validation of Children’s Responsible Environmental Behavior Scale

Though environmentally responsible behavior (ERB) has been a focus of many studies in the field of environmental education, very few scales have been developed to assess children’s ERB. In this regard, this article focuses on the development and validation of Children’s Responsible Environmental Behavior Scale (CREBS) and also reports the psychometric properties of this scale. The items in the CREBS were developed initially from the responses to four open-ended items by 229 fourth and fifth grade students. This initial form was pilot tested with 673 fourth and fifth graders and then subjected to exploratory factor analysis. Later, the revised version of the scale was administrated to 2412 fifth graders, and those results were subjected to confirmatory factor analysis and reliability analysis. CREBS consists of 23 items measured using a seven-point Likert-type scale, which have been organized into four sub-scales: political action (six items, α?=?.92); eco-management (six items, α?=?.70); consumer and economic action (five items, α?=?.70); and Individual and Public Persuasion (six items, α?=?.80). Study results indicate that CREBS can be used for exploring the extent to which elementary school students in Turkey demonstrate four types of behavior to help prevent and resolve environmental problems and issues.     

新疆双语教育跨越式发展的问题与对策研究

双语教育是发展新疆民族教育事业的一项战略措施.要适应新疆跨越式发展和长治久安战略实施的需要,推进双语教育跨越式发展,必须切实提高科学推进少数民族学前和中小学双语教育政策的执行力度,坚持采取多种有效措施,加强高素质双语教师队伍建设;健全双语教师评价和激励机制,吸引大批优秀人才从事双语教育工作;高度重视双语教育的科学研究工作,强化对教学实践的指导作用;充分有效地发挥现代远程教育设备在双语教学中的作用,重视发挥民汉合校和集中办学规模优势,大面积提高双语教育质量;坚持以传承中华文化为核心,高度重视文化交流交融,促进各民族之间的相互理解与认同.     

Content analysis of selected features of K‐8 environmental education research studies in Turkey, 1997–2007

This study aimed to analyze environmental education research (EER) in Turkey conducted in Grades K‐8 and published over the years 1997–2007. Due to the fact that there had been no systematic reviews of EER in Turkey prior to this time period, it was more appropriate to explore the implications of the results of this review for research policies and practices than for educational policies and practices in Grades K‐8. A substantial search of the international and national literature revealed 53 studies that fit the time frame and study characteristics. Three analyses of these studies were undertaken: (a) features of the research method; (b) socio‐demographic characteristics of the subjects; and (c) components of environmental literacy assessed. Three charts were constructed to support these analyses; e.g., one for each analysis. For analysis (a), quantitative surveys were the most common method. For analysis (b), greater attention was paid to the age, grade level, gender and residence of participating students. For analysis (c), greater attention was paid to knowledge of ecology and natural history, and knowledge of environmental problems and issues, less attention was paid to components of affect, and very little attention was paid to socio‐political‐economic knowledge, cognitive skills and environmentally responsible behavior.     

Analysis of the insulation capability of polyester insulator

The lifetime of polyester resin samples has been determined with the ASTM D2303 inclined plane tracking test method (IPTTM) for different environmental effects. Most of the external factors have a unique degradation effect, hence the tracking image observed on polyester resin highly depends on these factors. The structure and topography of the tracking patterns generated on the surface of polyester resin have been examined using the fractal dimension model. The accuracy and success of the fractal dimension model can significantly improve the possibility of determining the variety of aging processes that an insulator has been subjected to over a long time period. In order to verify the results, the structures have also been analyzed by using Markov random fields (MRF) and cellular neural networks (CNN).     

Internet plagiarism in higher education: tendencies,triggering factors and reasons among teacher candidates

While plagiarism has been a growing problem in higher education for a long time, the use of the Internet has made this increasing problem more unmanageable. In many countries, this problem has become a matter of discussion, and higher education institutions feel obliged to review their policies on academic dishonesty. As part of these efforts, the study aims to examine the tendencies of teacher candidates to plagiarise using the Internet, factors affecting their tendencies and the reasons for plagiarism. In this context, a questionnaire was administered to a total of 386 first- and fourth-grade college students at a college of education. The data were analysed using frequencies, percentages, the Mann–Whitney U test and Kruskal–Wallis one-way analysis of variance. The findings revealed that the teacher candidates had, to some extent, a tendency to plagiarise using the Internet by copying material or using the same assignment in different courses. Gender, department and length of computer use were found to be significant factors affecting their tendencies to plagiarise using the Internet. Time constraints, workload and difficulty of the assignments/projects were indicated as among the major reasons for tendencies towards Internet plagiarism.
