The reading comprehension and visual word recognition in 50 deaf children and adolescents with at least 3 years of cochlear implant (CI) use were evaluated. Their skills were contrasted with reference data of 500 deaf children without CIs. The reading comprehension level in children with CIs was expected to surpass that in deaf children without implants, partly via improved visual word recognition. Reading comprehension scores of children with implants were significantly better than those of deaf children without implants, although the performance in implant users was substantially lagging behind that in hearing children. Visual word recognition was better in children with CIs than in children without implants, in secondary education only. No difference in visual word recognition was found between the children with CIs and the hearing children, whereas the deaf children without implants showed a slightly poorer performance. The difference in reading comprehension performance of the deaf children with and without CIs remained present when visual word recognition was controlled for. This indicates that other reading-related skills were also contributing to the improved reading comprehension skills of deaf children with CIs. 相似文献

Historic parchment is a complex biological material, and due to various methods of production or inks used, unknown environmental histories of objects and heterogeneous nature of animal skin, it represents a particular analytical challenge. Due to the number of variables it is likely that patterns in degradation of these historic objects can only be revealed by surveying the material properties of a significant number of real objects. In this work, a sacrificial collection of ca. 100 historic parchments (fifteenth to twentieth century) was characterized using a range of techniques available to conservation practitioners that can usefully be used to reliably and rapidly characterize parchment. We focused on micro-destructive methods, such as shrinkage temperature (Ts), as the most widely used indicator of parchment degradation. Lipid content, roughness, and ink pH were additionally measured, while a limited number of samples containing iron gall ink were also examined using scanning electron microscopy (SEM) and SEM-EDX, to explore the distribution of ink components. Even in the absence of detailed environmental histories, it is possible to acknowledge the significance of the effect of iron gall ink and its acidity, and of lipids on parchment degradation, as measured using Ts. This research reports valuable reference data, while the collection remains accessible for further research. 相似文献

Publication bias promotes papers providing “significant” findings, thus incentivizing researchers to produce such findings. Prior studies suggested that researchers’ focus on “p < .05” yields—intentional or unintentional—p-value misreporting, and excess p-values just below .05. To assess whether similar distortions occur in communication science, we extracted 5,834 test statistics from 693 recent communication science ISI papers, and assessed prevalence of p-values (1) misreported, and (2) just below .05. Results show 8.8% of p-values were misreported (74.5% too low). 1.3% of p-values were critically misreported, stating p < .05 while in fact p > .05 (88.3%) or vice versa (11.7%). Analyzing p-value frequencies just below .05 using a novel method did not unequivocally demonstrate “p-hacking”—excess p-values could be alternatively explained by (severe) publication bias. Results for 19,830 p-values from social psychology were strikingly similar. We conclude that publication bias, publication pressure, and verification bias distort the communication science knowledge base, and suggest solutions to this problem. 相似文献

Recent research has highlighted the lack of a uniform definition of formative assessment, although its effectiveness is widely acknowledged. This paper addresses the theoretical differences and similarities amongst three approaches to formative assessment that are currently most frequently discussed in educational research literature: data-based decision making (DBDM), Assessment for Learning (AfL) and diagnostic testing (DT). Furthermore, the differences and similarities in the implementation of each approach were explored. This analysis shows that although differences exist amongst the theoretical underpinnings of DBDM, AfL and DT, the combination of these approaches can create more informed learning environments. The thoughtful integration of the three assessment approaches should lead to more valid formative decisions, if a range of evidence about student learning is used to continuously optimise student learning. 相似文献

The amount of data available in the context of educational measurement has vastly increased in recent years. Such data are often incomplete, involve tests administered at different time points and during the course of many years, and can therefore be quite challenging to model. In addition, intermediate results like grades or report cards being available to pupils, teachers, parents, and policy makers might influence future performance, which adds to the modeling difficulties. We propose the use of simple data filters to obtain a reduced set of relevant data, which allows for simple checks on the relative development of persons, items, or both. 相似文献

The aim of this study is to investigate the experiences of student teachers participating in an introductory course, designed to stimulate the development of a positive attitude towards research and to stimulate the development of research knowledge and skills by second-year student teachers of an institute of primary teacher education. A questionnaire (N = 81) was used to measure the students’ attitude and perceptions of the development of their attitude towards research, their perceived development of research knowledge and skills and what parts of the introductory course they perceived to be responsible for these developments. According to the students’ perceptions, the introductory course contributed to the development of both a positive attitude towards research and research knowledge and skills. The students indicated that examples from practice, authentic learning tasks and working in pairs or groups contributed most to the development of their attitude, knowledge and skills. 相似文献

The shortage of school leaders, mainly caused by the growing complexity of the job is steadily growing in recent years. This study reports on the results of a comparative empirical study into the causes of premature departure for male and female principals in primary and secondary education. Principals who have experienced premature departure themselves served as respondents. The risk factors for premature departure were researched in four areas: the school organization, the working environment including the school culture, the selection procedure and the principal him or herself. The results showed that the causes of premature departure are a combination of factors that are embedded in the context in which the leadership is performed and personal characteristics of the principal. 相似文献

ABSTRACT The use of written knowledge tests in (medical) education is widespread. Only few of them are thoroughly validated. Usually, validity studies are restricted to establishing ‘face‐validity’, the apparent similarity between test‐material and real life problems. Reliability studies are usually restricted to estimation of the coefficient alpha, representing the reproducibility of rank‐ordering of students at repeated test administration. This study addresses reliability from a broader perspective, using generalizability theory. The approach enables faculty to gain insight into the suitability of the test to serve different educational goals. A written knowledge test was examined, applied in postgraduate training for general practice in the Netherlands. Test‐reliability was approached from different perspectives: the norm‐oriented perspective, aiming at rank‐ordering (groups of) students, the domain‐oriented perspective, aiming at determining the absolute score level of (groups of) students and the decision‐oriented perspective, aiming at taking pass‐fail decisions. Reliability estimates differed for the different perspectives. The implication of the results and feasible options to increase reliability are discussed. 相似文献
