The results of large-scale international assessments such as Programme for International Student Assessment (PISA) have attracted a considerable attention worldwide and are often used by policy-makers to support educational policies. To ensure that the published results represent the actual population, these surveys go through a thorough scrutiny to ensure their validity. One important issue that may affect the results is the occurrence of different participation rates across groups with heterogeneous average student scores. In this study, we illustrate how problems of representativeness of the samples may be corrected by the use of post-stratified weights. We use the case of Portugal, a country where we uncover a meaningful difference between the actual population and the PISA samples in terms of the distribution of students per grade and track of studies. We show that after post-stratification, the temporal evolution of the PISA scores is quite different from the one reported.  相似文献

In this study we have used data from Spanish public universities to assess their efficiency in a longitudinal framework between 2008/9–2014/15. To carry out the analysis, two windows data envelopment analysis and intertemporal, non-radial and radial analysis methodologies were compared. The main results show a significant deterioration in university efficiency from the 2012/13 academic year for the three proposed frontiers, with both methodologies. Some factors may explain these results, such as the ageing of teaching force and its low replacement rate of 10%, and the lack of incentives for young researchers who wish to pursue a research career, influenced by the presence of endogamy, in hiring or promotion. Finally, the resources necessary for the good governance of the Spanish public university with the consequent accountability of these, in terms of teaching, research and its transfer to society, could become a strategic issue that should be taken into account by all the actors involved.

Family is an important context for cultural development, but little is known about the contributions of siblings. This study investigated whether older siblings’ cultural orientations and familism values predicted changes in younger siblings’ cultural orientations and familism values across 2 years and tested sibling characteristics and younger siblings’ modeling as moderators. Participants were 246 Mexican-origin younger (Mage = 17.72; SD = 0.57) and older siblings (Mage = 20.65; SD = 1.57) and their parents. Findings revealed that older siblings’ Anglo orientations and familism values interacted with younger siblings’ modeling: When younger siblings reported high modeling, older siblings’ Anglo orientations and values predicted increases in younger siblings’ Anglo orientations and values. Discussion highlights the importance of siblings in cultural socialization.  相似文献

Verbal and nonverbal forms of developmental learning disabilities have been reported. Whereas there are several instruments for evaluating children for the presence of verbal learning disabilities at school, no screening tool is available to identify children who have nonverbal learning disabilities. This study aimed at devising and validating a short screening questionnaire that can be used by teachers in primary schools to identify those children who need to be referred for clinical services because they have a visuospatial learning disability (VSLD). An 18-item Shortened Visuospatial Questionnaire (SVS) was derived from an earlier, longer version. Its validation procedure was twofold and was achieved by (a) verifying that children who had been identified with the SVS questionnaire as having a VSLD actually showed visuospatial deficits on psychometric evaluation and by (b) rating with the SVS a clinically identified population of children with VSLD. The results of the validation procedure showed that the SVS is a quick, reliable, and valid instrument that may be helpful in identifying children with VSLD in primary school.  相似文献

The current study examined how adolescents' ethnic‐racial identity (ERI) informed the demographic diversity of their friendship network (Goal 1) and the extent of similarity between adolescents' and their friends' ERI (Goal 2). Participants were sixth and seventh grade students (= 353; Mage = 11.88, SD = .73; 50% girls; 29% African American, 31% White, 13% Latino) in the Midwestern U.S. Results from longitudinal cross‐lagged models (Goal 1) indicated that having more diverse friendships at T2 was associated with greater T3 ERI exploration among all youth. In addition, boys who reported higher ERI resolution at T1 had more diverse friendships at T2. Furthermore, findings from longitudinal social network analyses (SNA; Goal 2) suggested that influence drove similarity between adolescents and their friends in ERI exploration and resolution.  相似文献

The impact of lighting, heating and people in re-using historical buildings are discussed for the case study concerning the ceremony room (i.e. the Giant Hall) of a mediaeval palace in Padova. The Hall has substantially four major problems for conservation: (i) the impact of heating, lighting and people when the room is used; (ii) many cracks on the oak panels of the coffered ceiling; (iii) the soiling by dust and soot particles deposited on the frescoes; (iv) the stained glass windows. A microclimate study was performed to know the impact of the environmental variables, and the use of the room, on the artworks preserved inside. The study has proved the impact of the lamps (both incandescence and compact fluorescent lamps) on the ceiling, the penetration of external air in the room, the heat and the moisture released by people, the impact of sunshine through windows and the scatter diagram of the daily cycles in temperature (T) and relative humidity (RH). During winter concerts, the strips of lead which are wrapped round the edge of the cut glass pieces in stained glass windows easily drop below the dew point and form condensation, starting corrosion. A discussion concerns the allowed variability, which should not exceed risk thresholds. A safe interval can be established within the area determined by the most frequent T and RH natural cycles. In fact, both of the cycles were compatible with the artefacts, or the artefacts were already damaged to allow the exceeding dimensional changes. Attention should be paid in the variability external to this area, especially approaching or exceeding a limit equal to twice the mode of the natural variability.  相似文献

This study explores the influence of self-assessment of vocabulary competence on a group of students’ oral fluency. Twenty-four young adult learners participated in a learning process that promoted their oral skills and vocabulary development. Self-assessment was mainly examined through the analysis of students’ learning logs, field notes and artefacts in the form of audio recordings. By contrasting and analysing data sources, and the results obtained from pre- and post-speaking tasks, through a mixed method design approach, it was found that when students self-assess, they are able to acknowledge their learning strengths and drawbacks. This practice enabled students to set learning commitments, use learning strategies that also allow them to raise awareness and take further actions, while self-monitoring them. Consequently, initial improvements in students’ oral fluency development were evinced through the implementation of a systematic cycle that applies self-assessment as a formative assessment source. Thus, the students entered a process in which they gradually become more able to self-monitor, judge and react towards their own gains in language and learning. Findings highlighted the value of goal setting as an essential component in self-assessment. Further longitudinal studies may well support the long-lasting effects of this strategy in similar educational contexts.  相似文献

Does alphabetic-phonetic writing start with the proper name and how does the name affect reading and writing skills? Sixty 4- to 5½-year-old children from middle SES families with Dutch as their first language wrote their proper name and named letters. For each child we created unique sets of words with and without the child’s first letter of the name to test spelling skills and phonemic sensitivity. Name writing correlated with children’s knowledge of the first letter of the name and phonemic sensitivity for the sound of the first letter of the name. Hierarchical regression analysis makes plausible that both knowledge of the first letter’s name and phonemic sensitivity for this letter explain why name writing results in phonetic spelling with the name letter. Practical implications of the findings are discussed.  相似文献

Research findingsThe study focused on 90 five-year-olds from fifteen Dutch schools. The children scored among the 30% lowest on literacy tests. Half were randomly assigned to a phonological skills program on the computer, the other half to a book program. Both programs consisted of 15 ten-minute sessions. During the phonological skills program children's mouse behavior was registered every tenth of a second. Intelligence, phoneme skills, and regulatory skills were tested. Children scoring average on regulatory skills benefited from teacher-free encounters with the phonological skills program, children scoring low or high did not. Typically, the lowest-scoring children showed more meaningless mouse activity and more random clicking.Practice or policyComputer programs can be used to stimulate early phoneme skills of poorly performing kindergarten children, but not for all children. Children with poor regulatory skills did not benefit from the intervention program.  相似文献
