This study investigated how measures of decoding, fluency, and comprehension in middle school students overlap with one another, whether the pattern of overlap differs between struggling and typical readers, and the relative frequency of different types of reading difficulties. The 1,748 sixth, seventh, and eighth grade students were oversampled for struggling readers (n = 1,025) on the basis of the state reading comprehension proficiency measure. Multigroup confirmatory factor analyses showed partial invariance among struggling and typical readers (with differential loadings for fluency and for comprehension), and strict invariance for decoding and a combined fluency/comprehension factor. Among these struggling readers, most (85 %) also had weaknesses on nationally standardized measures, particularly in comprehension; however, most of these also had difficulties in decoding or fluency. These results show that the number of students with a specific comprehension problem is lower than recent consensus reports estimate and that the relation of different reading components varies according to struggling versus proficient readers.  相似文献

This analysis is concerned with the horizontal and vertical consensus of definitions of work appropriate to accomplish the goals of university administrators and faculty, as well as the congruency of ideal (intent) and actual (action/behavior) work of faculty. Data-gathering techniques include the following: historical analysis of the university; interviews with the provost, 5 college deans, and 32 chairpersons; and a survey of 503 faculty (69% return rate). Faculty work perceived to achieve departmental goals lacked horizontal consensus, especially among chairpersons in the same college and among faculty in the same department. Vertical consensus was weak, especially between chairpersons and their faculty, and in most colleges between deans and chairpersons. Greatest incongruencies were between faculty intentions and reported actions. There was declining support for administrative goals as one moved down the hierarchical structure within the university. Perspectives were explored that account for the lack of goal consensus and the incongruency between intentions and reported actions.  相似文献

This paper summarizes the results of a study designed to determine why teachers did not use a teaching approach which was recommended by curriculum planners. The study indicated that teachers assessed the innovation with regard to itsefficiency for covering the syllabus, itscongruency with the expectations of significant others and whether its use entailed anyundesirable consequences. Each of these criteria was directly influenced by the overall need to select pupils in Hong Kong, which was manifested in the importance attached to the public examination. These findings are discussed in the light of available models for explaining how teachers react to innovations and with reference to the strategy of curriculum development utilized in Hong Kong.
Zusammenfassung Dieser Bericht faßt die Ergebnisse einer Studie zusammen, deren Sinn es war, herauszufinden, warum ein von Curriculumplannern entworfenes Lehrprogramm von den Lehrern nicht benutzt wurde. Die Studie ergab, daß die Lehrer die Innovation hinsichtlich ihrerWirksamkeit bewerteten, den Lehrplan vollständig zu behandeln, ihrerÜbereinstimmung mit den Erwartungen von anderen maßgeblichen Seiten und ob ihre Anwendung irgendwelcheunerwünschte Folgen mit sich brachte. Jedes dieser Kriterien wurde unmittelbar beeinflußt durch das allgemeine Bedürfnis, in Hong Kong Schüler auszuwählen, was sich aus der Bedeutung, die öffentlichen Prüfungen beigemessen wurde, ergeben hatte. Diese Befunde wurden in Hinblick auf verfügbare Modelle diskutiert. Diese sollten der Klärung der Frage dienen, wie Lehrer auf Innovationen und auf Strategien der Curriculumentwicklung in Hong Kong reagieren.

Résumé Cet article présente les résultats d'une étude menée pour savoir pourquoi les enseignants n'ont pas fait usage d'une approche d'enseignement recommandée par les planificateurs du curriculum. L'étude a révélé que les enseignants ont évalué l'innovation par rapport à son efficacité à respecter le programme, sa conformité aux attentes des autres, et au fait de savoir si non usage entraînait des conséquences inattendues. Chacun de ces critères a été directement influencé par le besoin général de sélectionner des élèves à Hong Kong, besoin qui se manifestait dans l'importance attachée à l'examen du public. Ces résultats sont examinés en vue de trouver des modèles valables permettant d'expliquer pourquoi les enseignants ont telle ou telle réaction envers les innovations et par rapport à la stratégie de développement du curriculum mise en place à Hong Kong.

Three runway experiments tested a stage model of extinction which postulated an orderly succession of three qualitatively different stages: habit, trial and error, and resolution. The model predicted that Stage 1 should be characterized by perseveration of habitual routes (i.e., response persistence) and the absence of competing responses; Stage 2, by an increase in investigatory behavior (response variation and hole exploration) and biting behavior; Stage 3, by a decrease in the competing responses of Stage 2 and continued increase in goal avoidance and substitution behavior (e.g., sand-digging). These predictions were largely confirmed. Further, Experiments 1 and 2 showed that, as expected by the model, continuous reinforcement (CRF) resulted in more practice of habitual routes in acquisition and greater response persistence, while partial reinforcement (PRF) resulted in more route variation and hole exploration in acquisition and greater goal persistence which was attributable to prior reinforcement of a trial-and-error coping strategy. Results of Experiment 3, which combined training trials and reward magnitudes orthogonally, supported the prediction that response persistence was positively related to training trials, and goal persistence negatively related to reward magnitudes. All three experiments demonstrated an inverted-U function in investigatory and biting behavior, as predicted by the stage model.  相似文献

This paper presents an analysis and discussion of the opinions of two generations of Asian parents with regard to their young children's education. A large number of parents (n = 200) were interviewed during 1970-1974 and a smaller number (n = 40) during 1995 to ascertain their views on a variety of topics relating to their children's early education. The findings are discussed in a qualitative way and reveal the increasing satisfaction of Asian parents with their children's education. A higher proportion of the mothers of the 1990s help their children with homework, read them stories and are generally more participatory in their children's education compared with the 1970s group. The second generations are concerned with the lack of facilities for the teaching of mother tongues in schools. These and other findings are discussed within the changing lifestyles of second-generation Asians.  相似文献

The current longitudinal study examined the development of general cognitive abilities of 4–6-year-old children of low-income, ethnic-minority families in preschool over two and a half years by determining the changes in general, and in verbal and fluid cognitive abilities, relative to age norms, using an intelligence test. The results revealed significant increases over time, relative to age norms, in full scale and in both verbal and fluid intelligence test scores of disadvantaged children, with medium effect sizes. These gains in measured intelligence were moderated by children's home language and age. Children who gained most also profited most from their increased abilities with respect to emergent school skills. Gains in verbal intelligence predicted emergent school vocabulary, but gains in fluid intelligence did not. Overall, gains in fluid intelligence predicted emergent math skills, and gains in verbal intelligence predicted emergent math skills only among older children.  相似文献

This article looks at the concept of Black History Month and its implications for teaching and learning in art and design education. It argues that the concept of Black History Month should be discarded because it tends to promote a separatist notion of culture and that it deflects from an understanding of culture as a plural and intermeshing process. The paper interrogates history as a discourse, problematising our use of the word. The article then looks through the eyes of two groups of African Caribbean young people at Black History Month, as a curriculum initiative. The first group was interviewed at a south London gallery and the second at a conference for African Caribbean learners in Oxford. Two art and design educationalists who participated in the research project that included the south London young people make a significant contribution to the paper. It concludes with a personal interpretation of movements in art and the practice of a contemporary artist whose work endorse the key philosophical position posited in the text that culture is always a process on interweaving.  相似文献

Due to the popularity of Web search engines, a large proportion of real text retrieval queries are now processed over collections measured in tens or hundreds of gigabytes. A new Very Large test Collection (VLC) has been created to support qualification, measurement and comparison of systems operating at this level and to permit the study of the properties of very large collections. The VLC is an extension of the well-known TREC collection and has been distributed under the same conditions. A simple set of efficiency and effectiveness measures have been defined to encourage comparability of reporting. The 20 gigabyte first-edition of the VLC and a representative 10% sample have been used in a special interest track of the 1997 Text Retrieval Conference (TREC-6). The unaffordable cost of obtaining complete relevance assessments over collections of this scale is avoided by concentrating on early precision and relying on the core TREC collection to support detailed effectiveness studies. Results obtained by TREC-6 VLC track participants are presented here. All groups observed a significant increase in early precision as collection size increased. Explanatory hypotheses are advanced for future empirical testing. A 100 gigabyte second edition VLC (VLC2) has recently been compiled and distributed for use in TREC-7 in 1998.  相似文献

Multicultural information dynamics is exploratory cross-cultural research of the information-seeking behavior of a group of eighty-four Egyptian and American reference librarians asked to choose from websites in different languages. This paper, the fourth in a series, focuses on national, monolingual, and multilingual subgroups, and provides multi-tiered analyzes of websites clicked, reasons given for clicking, preferences for machine translations vs. original foreign language websites, decision making when choosing non-native language hits, and foreign language anxiety. Findings of the research show that information seekers of both nationalities are reluctant to cross cultural lines at the basic level of retrieved Internet information hits. Further results delineate differences and similarities in motivations, circumstantial preferences for original languages or machine translations, and comparative information-seeking behavior of subgroups. The research has implications for improving search performance in the fields of global knowledge dissemination via website and search engine design, library science, and international scholarship.  相似文献
