The differences, so far as Yugoslav legislation is concerned, between “equivalence” and “recognition” are mads clear, and the Yugoslav instances authorized to make decisions on questions of equivalence and recognition are stated and their procedures, briefly described. The 7 multilateral conventions and the 13 bilateral agreements on equivalence and recognition matters are listed. More is said about the various Yugoslav instances empowered to make decisions and to give Information on questions of equivalence and recognition.  相似文献

This study investigated how two readers of Mandarin with differing reading‐proficiency skills interacted with a narrative passage, as well as what knowledge they brought to and made use of while reading the text. The perspectives of reading comprehension, transactional theory and social‐cognitive models of reading served as this study's theoretical framework. Two Sixth‐Grade participants were selected for inclusion through snowball sampling. The data in this study were obtained from interviews and think‐alouds. Qualitative analysis indicated that the skilled Mandarin reader's stance moved along the efferent/aesthetic continuum, while the less‐skilled Mandarin reader's was mainly efferent. The skilled reader employed strategies of inferencing, summarisation and synthesis during and after reading, while the less‐skilled reader applied bridging inferences, paraphrasing and repetition. The findings of this study corroborate previous findings that proficient readers employ more sophisticated approaches to reading than less‐proficient readers.  相似文献

Brain drain has been a long‐lasting phenomenon. It existed in the former Yugoslavia, and was affected by various factors, from political through economic ones to the attractive offers for advanced studies and work in scientific institutions or firms in developed countries. Some ad‐hoc analyses were made concerning individual groups or periods, but there was no systematic monitoring and no complete and all‐inclusive data. It is however possible to draw a picture showing trends in the – mostly one‐way – movement towards highly developed countries.

Therefore, the current study has a mosaic character, which – we hope – shall throw some light and try to explain brain drain in the academic circles of Serbia and Montenegro (former SFRY). As the Republic of Serbia represents the largest component part (about 90 percent), most of the data is about Serbia.  相似文献

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.  相似文献

On a hot summer morning in 1989 I finished packing my things in my flat in Dublin. Two suitcases were not enough to hold them all so I had to use plastic supermarket bags for the remainder. My friend Tom arrived in his car to take me to the airport. After coffee at the airport we shook hands and said goodbye and it was only then that I noticed my hand was shaking. My voice was also shaking and my breath was coming out in uneven waves. Tom was my good friend from schooldays and in saying goodbye to him I was saying goodbye to so many good memories, saying goodbye to my country.  相似文献

ABSTRACT

Background Research suggests that negative peer interactions that compromise student safety and wellbeing often occur in spaces at school that are not easily visible, not adequately monitored, overcrowded and/or relatively unstructured. In a large online survey conducted in Swedish schools by the anti-bullying organisation, Friends, a small proportion of students indicated that they felt unsafe in the school canteen and responded to a question about why they felt unsafe there. As the canteen is often reported to be a space where negative peer interactions, such as harassment, bullying and other forms of school violence, occur, but little is known about why negative peer interactions occur there, we were particularly interested in exploring why some students perceived their school canteen to be an unsafe space.

Purpose Taking a social-ecological perspective, our aim was to investigate why students reported feeling unsafe in the environment of the school canteen.

Method In order to investigate this question, we analysed 1,547 responses from students in Swedish schools in grades 3–6 (ages 9–12). The responses were from the anti-bullying organisation Friends’ online questionnaires from 2011 to 2016. In the responses, students who indicated that they felt unsafe in the school canteen explained why they felt this way. Data were analysed qualitatively, using a six-step thematic approach.

Findings The analysis identified four key themes: Space constraints, Time restrictions, The risk of social blunders and The negative actions of others. We discuss the findings in terms of the macrosystem, exosystem, mesosystem and microsystem.

Conclusions In matters of student safety and wellbeing, we argue that it is not only important to consider the social context, but also how that context is interconnected with environmental and structural elements.  相似文献

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan’s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy’s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers’ interviews, classroom observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top‐down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents’ expectations of and attitudes towards English learning also became an obstacle.  相似文献
