There has been considerable interest in national quality assurance process in Turkey following the pilot accreditation project of the Engineering College of the Middle East Technical University (METU) by the Accreditation Board for Engineering and Technology (ABET), in 2000. ABET accreditation of the Engineering Colleges of Bosphorus and Bilkent Universities followed that of METU. These universities use their accreditation by ABET to attract the best students in the country. Newly founded private universities, in particular, are trying to use the accreditation of their programmes by international accreditation agencies for marketing purposes. The Higher Educational Council [Yuksek Ögretim Kurumu (YÖK)], which governs all the universities in Turkey, is currently promoting accreditation studies to improve the quality of higher education in the universities. This is a report on accreditation processes in higher education in Turkey.  相似文献

This paper presents the results of two different investigations about the attitudes and opinions of the Finnish schoolchildren towards technology and engineering. One investigation was made with a written questionnaire answered by 2000 gymnasium students in age group 16–19 years; the other is a content analysis of the 707 writings in a national technology competition 1988. The writers were in the age group 13–19 years. These investigations were made to get information for recruiting students into engineering. Special emphasis was paid to find the difference between boys and girls.  相似文献

This study was carried out to investigate the effect of age and sex on the creativity of 5 to 6‐year‐old kindergarten children. The total points scored by the 6‐year‐old boys and girls included in this study were found to be higher than those scored by the 5‐y ear‐olds. No significant difference was found between the points scored by the girls and boys. However, the girls did better in flexibility, originality and elaboration and the boys in fluency criterion of creativity.

Children should be helped at home and school to develop their creative power. To achieve this, art, story‐telling, music and drama activities should be an integral part of the school curriculums. During such activities children should be allowed to take their time, and any despotic attitude on the part of the teacher should be avoided. In addition, children should be given a chance with unstructured play materials. Activities should be followed by a discussion with children, who should be taught that things can be done in more ways than one.  相似文献

This study examined the social‐cognitive reasoning of 52 Chinese Malaysian preadolescents (9–12 years old; M = 11.02, SD = 0.94) and 68 adolescents (13–18 years old; M = 14.76, SD = 1.39) in resolving filial dilemmas within the personal and moral domain. Preadolescents deferred to parental authority, whereas adolescents endorsed filial obligation reasoning to justify compliance in the personal domain. Both appealed to filial obligation, pragmatic, or welfare and safety reasoning to justify compliance but fairness or rights reasoning to justify their noncompliance, for the moral issue. Distinctions between authoritarian and reciprocal filial piety reasoning were revealed. Findings demonstrated complex decision‐making and cognitive reasoning processes among Chinese Malaysian adolescents as they negotiate their filial obligations and autonomy development.  相似文献

Abstract

This introductory article argues that practices of professional thinking and acting on the presence of the immigrant offer a privileged analytical prism through which to study how post-WWII European welfare nation-states have been shaped and crafted. As such, study of the formation of post-WWII welfare nation-states where one usually does not look for them is suggested: that is, beyond the bureaucratic logic imposed by the state itself. Consequently, a wedge is driven into the mundane professional practices embedded in the immigrant/welfare nation-state nexus, through which may be observed the very heterogeneous production of problems and solutions with immense effect on human lives, communities, and societies. These practices demonstrate the boundary work of the welfare nation-state that shapes it and gives shape to the construction and reconstruction of immigrant children and their families as problems and, thus, objects of integration and professional intervention. In this sense, the prism offers a new approach to writing histories of immigrant children’s education and the shaping and crafting of welfare nation-states that displaces both objects of study to professional practices of their making. In the first part of the article, the privileging of this analytical prism is substantiated historically and theoretically. In the second part, the four contributions constituting this themed issue are introduced. Finally there is a discussion of how the four contributions demonstrate the analytical prism’s cross-national relevance and historical sensitivity, adding new histories of how immigrant children’s education has been caught up in the immigrant/welfare nation-state nexus.  相似文献

In this study, the effect of conceptual-change-texts-oriented instruction to seventh-grade students' understanding of ecological concepts was investigated. Using information collected through interviews and related literature, the Ecology Concept Test was developed and administered to 58 elementary students in two classes of an elementary school before and after the treatment. The experimental group received conceptual-change-texts-oriented instruction and the control group received traditional instruction. Results of independent t test analysis revealed a statistically significant difference between the gain score means of the students in both groups with respect to ecological concepts in favor of experimental group after the treatment.  相似文献

Do more distant collaborations have more citation impact?   总被引:1,自引:0,他引:1  
Internationally co-authored papers are known to have more citation impact than nationally co-authored paper, on average. However, the question of whether there are systematic differences between pairs of collaborating countries in terms of the citation impact of their joint output, has remained unanswered. On the basis of all scientific papers published in 2000 and co-authored by two or more European countries, we show that citation impact increases with the geographical distance between the collaborating counties.  相似文献

Objective

This study aims to investigate the degree of biocompatibility and neuroregeneration of a polymer tube, poly-3-hydroxyoctanoate (PHO) in nerve gap repair.

Methods

Forty Wistar Albino male rats were randomized into two groups: autologous nerve gap repair group and PHO tube repair group. In each group, a 10-mm right sciatic nerve defect was created and reconstructed accordingly. Neuroregeneration was studied by sciatic function index (SFI), electromyography, and immunohistochemical studies on Days 7, 21, 45 and 60 of implantation. Biocompatibility was analyzed by the capsule formation around the conduit. Biodegradation was analyzed by the molecular weight loss in vivo.

Results

Electrophysiological and histomorphometric assessments demonstrated neuroregeneration in both groups over time. In the experimental group, a straight alignment of the Schwann cells parallel to the axons was detected. However, autologous nerve graft seems to have a superior neuroregeneration compared to PHO grafts. Minor biodegradation was observed in PHO conduit at the end of 60 d.

Conclusions

Although neuroregeneration is detected in PHO grafts with minor degradation in 60 d, autologous nerve graft is found to be superior in axonal regeneration compared to PHO nerve tube grafts. PHO conduits were found to create minor inflammatory reaction in vivo, resulting in good soft tissue response.  相似文献

Abstract

This report aims (1) to examine the association between seasonality and physical activity (PA) and sedentary time in European adolescents and (2) to investigate whether this association was influenced by geographical location (Central-North versus South of Europe), which implies more or less extreme weather and daylight hours. Valid data on PA, sedentary time and seasonality were obtained in 2173 adolescents (1175 females; 12.5–17.5 years) included in this study. Physical activity and sedentary time were measured by accelerometers. ANCOVA was conducted to analyse the differences in PA and sedentary time across seasons. Results showed that girls had lower levels of moderate to vigorous PA (MVPA) and average PA, and spent more time in sedentary activities in winter compared with spring (all < 0.05). Stratified analyses showed differences in PA and sedentary time between winter and spring in European girls from Central-North of Europe (< 0.05 for sedentary time). There were no differences between PA and sedentary time across seasonality in boys. In conclusion, winter is related with less time spent in MVPA, lower average PA and higher time spent in sedentary activities in European adolescent girls, compared with spring. These differences seem to mainly occur in Central-North Europe.  相似文献

The purpose of this study is to explore not only the effect of context-based physics instruction on students’ achievement and motivation in physics, but also how the use of different teaching methods influences it (interaction effect). Therefore, two two-level-independent variables were defined, teaching approach (contextual and non-contextual approaches) and teaching method (traditional and learning cycle methods). Thus, a 2?×?2 factorial design was performed with four treatment groups, including 131 11th-grade students: (1) a traditional method with the non-contextual approach group, (2) a traditional method with the contextual approach group, (3) a learning cycle with the non-contextual approach group, and (4) a learning cycle with the contextual approach group. Prior to and just after the treatments, which took 5 weeks, pre-tests and post-tests on student achievement and motivation were administered. For the analysis of data, multivariate analysis of covariance, simple regressions and follow-up analysis of covariances were performed. Consequently, it was found that the effect of context-based approach on physics achievement is dependent upon the teaching method implemented. That is, the traditional method was observed to increase the effect of the contextual approach while the learning cycle decreased it. Related to the effects on motivation in physics, no evidence was found to claim a significant difference. Based on the findings of this study, further research is suggested for determining which teaching methods are more effective with the context-based approach on students' achievement and motivation in physics.  相似文献
