In 1981, the career structure in Dutch higher education was modified in such a way that performance criteria, particularly possession of a doctorate and research and publication activity, were required for promotion. In particular, the hierarchy of university posts below that of full professor was modified in such a way that persons holding so‐called WHM(senior scientific staff level) positions were required to reapply for the new UHD(associate professor) positions on a competitive basis which stressed the publication record of candidates. Using a sampling of academic women drawn from the natural sciences, the authors offer an explanation as to why women academics did less well than men in the competitions for these new posts. Although the process did not discriminate against women as such, it did not favour academics on the periphery of the profession, where many women at the time found themselves. The situation identified was the result of social factors more than of institutional discrimination. Presently, younger women ‐graduate students ‐ are rapidly moving from the periphery of the profession to the centre. Active involvement in professional networks will aid academic women in their careers; however, over‐involvement in family matters (the care network) may be harmful to the career progress of academic women.  相似文献

This study aimed to investigate the relationship of classroom composition factors with reading and listening comprehension achievement and progress in socially and ethnically segregated primary schools in Flanders (Belgium). Specifically, using a three‐level multivariate repeated measures analysis, it examined the association of reading and listening achievement and progress with ethnic diversity, the proportion of non‐native students and the average socioeconomic status of the class, taking into account student characteristics. At the beginning and end of the school year, reading tests, listening tests and questionnaires were administered to a sample of 7‐ and 8‐year‐old students (n = 683) in 42 second‐grade classes. Students' listening comprehension achievement at the beginning of the school year was negatively related to having a home language other than the language of instruction and to classes with a high proportion of non‐native students. However, progress in listening comprehension was not significantly associated with any student or classroom composition factors. Students whose mothers had a lower level of education performed lower on reading comprehension at the beginning of the school year, while at the end of the school year students whose mothers had a higher level of education were at a greater disadvantage. Limitations of this study and directions for future research are discussed.  相似文献

A comprehensive, quantitative evaluation of an educational intervention program designed to reduce the attrition of minorities from the biological sciences was undertaken to ascertain whether such efforts adequately address the problem. Program participants had greater odds of persisting in basic math and science courses, and of graduating in biology, than did a comparison group, controlling for demographics and academic preparation. Undergraduate research greatly increased the odds of positive graduation outcomes. Program participants were also more likely to pursue graduate study than were university graduates overall. This evaluation demonstrates the value of such programs in increasing the representation of minorities in science. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 861‐881, 2004.  相似文献

ABSTRACT

When searching for information on the Internet, it can be stored in a bookmarking system. The ability to organize this information in such a system depends on one’s own prior knowledge to create an appropriate classification scheme. Providing a classification system for bookmarks might support people with low prior knowledge. Even though different bookmarking systems exist, hierarchical menus and tagging are being most widely used. In the current exploratory study with 95 ninth-grade students, a 2 × 2 between-subjects design was used to investigate the influence of providing classification support (or not) for either a tagging or a hierarchical system. Results showed that despite the low familiarity with tagging systems, using a hierarchical system is not necessarily a better approach than using a tagging system to organize previously found information. Rather, a tagging system seems to yield storage of fewer but higher-quality information sources. The most important conclusion is that, despite the low familiarity with tagging systems, using a hierarchical system was not beneficial over using a tagging system to organize previously found information.  相似文献

This paper reviews psychological research on programming and applies it to the problems of learning and teaching Prolog. We present a psychological model that explains how a certain class of errors in programs comes about. The model fits quite well with the results of a small sample of students and problems. The problems that underlie these and other errors seem to be (a) the complexity of the Prolog primitives (unification and backtracking) and (b) the misfit between students' naive solutions to a problem and the constructs that are available in Prolog (e.g. iterative solutions do not map easily to recursive programs). This suggests that learning Prolog could be helped by (1) coherent and detailed instruction about how Prolog works, (2) emphasis on finding recursive solutions that do not rely on primitives such as assignment and (3) instruction in programming techniques that allow students to implement procedural solutions.  相似文献

This paper not only makes a contribution to the mosaic of scientific knowledge of the brain and nervous system, but suggests implications of practical value. Observant, experienced teachers know empirically that some youngsters learn best, and perhaps only, when seated front-center, right before the teacher’s desk. Such children need to have the eye contact, or to be in quick arm’s reach, or to have distractions screened out. Drs. Bakker and Van Rijnsoever give evidence here that, for many children, taking in and remembering the message is dependent on their physical placement to catch most effectively the stream of sound. This is important to consider in the popular open classroom. Although many children can adapt readily to less-than-perfect physical learning conditions, for some we must “re-invent the wall,” not to climb, but to provide a place to call “home.” The theoretical re-inforcement presented in this paper proves that such boundaries can also provide source and direction for sound as part of some children’s currently needed sensory security and enhance the efficiency of their auditory intake.

In 1996–1997, within the framework of the European Observatory for Population Education and Information, a comparative survey was conducted among students in final classes of secondary education in several European countries. On the one hand, the survey attempted to assess the effects of education on population in terms of knowledge acquired; the issues addressed in the questionnaire pertained to knowledge of demographic facts and trends (such as the ageing of Western societies and immigration). On the other hand it tried to ascertain students' opinions on demographic trends. What are young people's views on intergenerational solidarity, how tolerant are they towards immigrants, what are their views on recent changes in family structures? This knowledge is important since it is young people's attitudes and future behaviour that will help to shape both the social tissue and the economic prosperity of the European and world population. In this article we present a comparative analysis of survey results obtained in five European countries. We examined the question whether knowledge acquired in the course of scolarisation influences opinions. The results evidence a significant relationship between knowledge of the migrants' issue and attitudes of tolerance towards migrants. By means of multivariate analyses, the impact of factors such as social origin, study orientation and gender on both students' knowledge and attitudes, are investigated. We conclude that adequate educational training on population issues can have a significant positive impact on attitudes of tolerance.  相似文献
