Methods of test equating and scaling have been studied in the statistically advanced literature of educational and psychological measurement, and applied extensively where mass testing and selection procedures are required; for example, selection for tertiary study. Usually the procedures themselves require large data sets, and they are applied in order to ensure that students are not advantaged or disadvantaged because of the arbitrary features of the origin and units of measurement of the various tests. However, equating may be necessary where the data sets are relatively small. This paper provides an example of selection into a professional faculty within a university, following study from a range of subjects available in various faculties at the first-year level, and shows the need and a procedure for equating the grades in the different subjects. The procedure itself is based on a psychometric model studied extensively in the psychometric literature, and the purpose of this paper is to introduce the rationale for its application from first principles for a broader professional education audience and to illustrate its application with a practical example. 相似文献
Despite its relevance in theoretical and practical terms, braille reading has received little attention from researchers. Awareness of the pros and cons of the different procedures used to examine braille reading is needed to facilitate the realization of systematic studies and to improve teaching methods in braille reading. This study provides a critical examination of braille reading methods and highlights key points for future studies on tactile reading. 相似文献
An increasing number of studies are concerned with the international comparison of the results that different education systems achieve. For example, TIMSS, PIRLS and PISA publish the results from different countries in mathematics, science and literacy. The European Commission has also published indicators and benchmarks relating to the quality of school education. This type of external evaluation is often perceived by teachers as judgemental and controlling. In contrast, internal school‐based evaluation aims to be seen as a developmental process contributing to improved teacher and student learning, where ownership of the evaluation processes remains with the school stakeholders. This paper examines the possible tensions and conflicts that may arise between these two types of evaluation and asks the question ‘How can we overcome the negative attitudes that may have resulted from external evaluation in order to encourage schools to undertake internal school‐based evaluation?’ The paper explores, using Scottish case studies, ways in which schools through their internal self‐evaluation processes may use the data in different ways to meet some, if not all, of the external demands placed on them. This strategy, it is argued, ensures that evaluation is largely done for school purposes and as an aid to the learning process, rather than as an external assessment designed to hold schools accountable for the learning achieved to date.
Il y a un nombre grandissant d'études qui s'occupent de la comparaison internationale des résultats atteints par de différents systèmes éducatifs. Par exemple, TIMSS, PERLS et PISA publient les résultats de différents pays en maths, en sciences et en alphabétisation. La Communauté européenne publie aussi des indicateurs et des standards qui se rapportent à la qualité d'éducation dans les écoles. Ce genre d'évaluation externe est souvent perçu par les enseignants comme un moyen de jugement et de contrôle. Par contraste, les évaluations internes, basées et créés dans les écoles essaient d'établir un processus de développement qui contribue à améliorer l'apprentissage des enseignants et des étudiants et qui es la copropriété des preneurs de l'école. Cet article examine les tensions et les conflits qui peuvent se présenter entre les deux genres d'évaluation et pose la question: “Comment peut‐on combattre les attitudes negatives qui résulteraient après des évaluations externes et comment peut‐on par la suite encourager les écoles à entreprendre leur propre évaluation externe?”Plus particulièrement, en utilisant des études de cas de quelques écoles en Ecosse, l'article explore aussi les moyens par lesquels les écoles peuvent utiliser les données obtenues par les processus d'auto‐évaluations internes afin d'adresser au moins quelques‐unes des exigences externes qui s'imposent à l'école. Cette strategie, l'on soutient, garantit que l'évaluation bénéficit en grande partie aux méthodes d'enseignement à l'école au contraire des évaluations externes qui généralement poussent les écoles à rendre des comptes.
Eine zunehmende Anzahl von Untersuchungen befaßt sich mit dem internationalen Vergleich der Leistung, die in verschiedenen Ausbildungssystemen erzielt wird. Zum Beispiel veröffentlichen TIMSS, PIRLR und PISA die Ergebnisse von verschiedenen Ländern in den Bereichen Mathematik, Naturwissenschaften und Lesen/Schreiben. In Bezug auf die Qualität schulischer Ausbildung hat die Europäische Kommission auch Indikatoren und Anforderungsmaßstäbe veröffentlicht. Diese Art von externer Evaluation wird von Lehrern oft als bewertend und als ein Element von Steuerungsmaßnahmen angesehen. Im Gegensatz dazu sollte die interne schulbezogene Evaluation, deren Kontrolle bei den Betroffenen in der Schule verbleibt, als Teil eines Entwicklungsprozesses aufgefaßt werden, der auf die Verbesserung des Lernens von Lehrern und Schülern abzielt. Dieser Beitrag untersucht die möglichen Spannungen und Konflikte, die sich aus den beiden verschieden Evaluationsansätzen ergeben. Es wird die Frage aufgeworfen: “Wie können wir die negativen Einstellungen, die mit externer Evaluationen leicht verbunden sind, überwinden, um damit die Schulen bereit zu machen, interne schulbezogene Evaluationen durchzuführen?” Auf der Grundlage von schottischen Fallstudien zeigt der Beitrag Möglichkeiten auf, wie Schulen im Rahmen von internen Selbstevaluationsprozessen Daten verschiedenster Art nutzen können, um zumindest einigen Anforderungen, die an sie von außen gestellt werden, genügen zu können. Die Verfasser gehen davon aus, daß eine solche Strategie sicherstellt, daß die Evaluation im wesentlichen für schulische Zwecke durchgeführt wird: Daß sie vor allem den weiteren Lernprozeß unterstützt und weniger einer externen Beurteilung dient, die darauf ausgerichtet ist, Schulen für ihre bisherigen Lernleistungen zur Verantwortung zu ziehen.
Ultimamente ha habido un incremento importante de estudios sobre los resultados que han obtenido diversos sistemas educativos en comparaciones internacionales. Por ejemplo, TIMSS, PERLS y PISA publican los resultados de diversos países en matemáticas, ciencias y alfabetización. La Comisión Europea también ha publicado indicadores y bases de datos, referidos a la calidad de la educación de las escuelas. Este tipo de evaluación externa a menudo es percibido por los profesores como un control y una crítica a su labor. En contraste, la evaluación interna realizada desde la escuela, apunta a ser considerada como un proceso de desarrollo profesional que contribuye a la mejora del profesorado y al aprendizaje de los alumnos, y donde el propietario del proceso de evaluación es el mismo centro educativo. Este documento examina las posibles tensiones y los conflictos que pueden darse entre estos dos tipos de evaluación y se pregunta, “¿cómo podemos superar las actitudes negativas que pudieron originar la evaluación externa de manera que se pueda animar a las escuelas a emprender una evaluación interna desde la escuela? El documento explora, usando estudio de casos escoceses, las maneras en las cuales las escuelas a través de sus procesos de autoevaluación interna pueden utilizar los datos de diversas maneras y dar respuesta a algunas, sino a todas, las demandas que reciben del exterior. Esta estrategia, se dice, que asegura que la evaluación esté hecha en gran parte para el propósito de la escuela y como ayuda al proceso de aprendizaje más que un examen externo diseñado para que las escuelas rindan cuentas sobre los resultados que han obtenido. 相似文献
The issue of sex differences in reading disability has been of recent interest in relation to sex ratios in families with reading disabled children and to possible sex biases in referred populations. Data from a study of 570 twins are used to develop alternative definitions of reading disability that vary in the manner to which sex effects are taken into account. These definitions include discrepancies between reading quotients and IQ, the use of the regression of reading onto IQ and chronological age/reading age differences. In each case the reading and spelling disability was defined either separately for the sexes or based upon the data for the sexes combined and with and without an IQ>90 exclusion criterion. The consequences of using the alternative definitions for prevalence, sex ratio and heritability are examined. The results demonstrate that the characteristics of reading disabled children vary with the way disability is defined. The excess of males seems to be a robust finding. Definitions that take into account differences in mean score for males and females reduce but do not eradicate the sex ratio. From the genetic analysis, there is no support for the suggestion that the genetic effect on reading is greater for females than males. It is concluded that the use of regression based procedures for identifying reading disability is desirable but that at present there is insufficient evidence to justify the adoption of separate regression procedures for the two sexes. 相似文献
Sustained professional development can support STEM (Science, Technology, Engineering, and Mathematics) reform. The authors describe a 3-year study of sustained professional development for 3 diverse urban schools across the salient factors of fidelity of implementation of project-based learning, development of professional learning communities, and student achievement. Qualitative and quantitative data were collected. The students who experienced the greatest fidelity of implementation exhibited the greatest gains (d = 1.41–2.03) on standardized test scores, while those with the lowest fidelity of implementation exhibited negative gains (d = –0.16 to –0.08). Qualitative data indicated teachers perceived there were multiple benefits from the implementation of project-based learning. 相似文献
The basic multiple regression model for the analysis of selected twin data (DeFries and Fulker 1985, 1988) was fitted to spelling data from 100 pairs of MZ twins and 71 pairs of same-sex DZ twins tested in the Colorado Reading Project (DeFries, Olson, Pennington and Smith 1991), and to data from 12 pairs of MZ twins and 15 pairs of same-sex DZ twins tested in the London twin study of reading disability (Stevenson, Graham, Fredman and McLoughlin 1984, 1987). Estimates of hg2
obtained from analyses of these data suggest that about 60% of the deficit of probands is due to heritable influences in both samples. When a regression model was fitted separately to data from males and females in the combined Colorado and London samples, resulting estimates of hg2
were 0.66±0.18 and 0.56±0.19, respectively, a nonsignificant difference. Collaborative analyses of data from additional twin studies of reading disability would facilitate more rigorous tests of hypotheses of differential genetic etiology as a function of group membership. 相似文献
The aim of this paper is to analyse certain techniques of subjectivation in modern child-rearing and the way in which medical discourse leads to the construction of children through those techniques. As a case study, several manuals on childcare used during the first third of the twentieth century in Spain and France have been selected. A historical-genealogical perspective is adopted, according to which childhood is not a natural or ahistorical category, but depends on cultural practices. In Western countries, these practices have been strongly influenced by expert discourses. The techniques proposed in the manuals are identified and the theoretical justification for them analysed according to the socio-cultural and historical context. It is shown in what sense the practices recommended by doctors for mothers constituted a kind of early informal education contributing to the creation of future well-educated citizens. 相似文献
