In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between 6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade. The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading comprehension.  相似文献

The Netherlands form a consensus democracy. In such a society the legitimacy of decisions is of great concern to all. An elaborate system of checks and balances tends to exist and the pressure to join an emerging consensus at meetings is both subtle and tremendously powerful. In the Dutch system of higher education and research the manifestations of the consensus ideal are numerous. This paper highlights them where appropriate. It reviews the Dutch research effort in an international perspective and concludes that R&D expenditure in the Netherlands, measured as a proportion of GDP, is declining. Fairly radical changes in science policy orientation since the 1960s are reviewed and the current frameworks for policy formulation, academic foresight and the organisation of support are sketched. After discussing NWO's different funding instruments, the practices of picking the winners are described in some detail. Three different peer review models are then discussed with special attention to their strengths and weaknesses. The paper's final section is focussed on the evaluation practices in force.  相似文献

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

We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.  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
