This paper investigates how pupils' growth trajectories in three language domains (reading fluency, spelling, and reading comprehension) are related to their own socioeconomic and ethnic background and to the socioeconomic and ethnic composition of their primary school. Using multilevel piecewise growth curve analysis, the growth trajectories of approximately 5000 pupils from 170 primary schools were estimated. The results indicate that a pupil's socioeconomic and ethnic backgrounds have the largest impact on achievement and growth in reading comprehension and the smallest impact on reading fluency. Furthermore, school ethnic composition—but not socioeconomic composition—was related to pupils' achievement in all three language domains at the first measurement occasion, though none of the types of school composition was related to growth. The research findings therefore imply that to combat the deficits in language proficiency often found in ethnic minority pupils, priority should be given to investments in individual intervention programmes over policy plans to desegregate schools. Moreover, our study identifies the specific points in time during primary school at which intervention programmes are needed the most.  相似文献

In this study, we examine the development of referential communicative regulation, incorporating the Vygotskian notion of private speech. From this perspective, private speech may serve a regulatory role when the child speaker is focused on what to say when speaking to others. In a longitudinal study carried out with 10 pairs of children with a mean age of 4.5, 6.5, and 8.5 years, we analyzed the relationship between the capacity of the child in the speaker role to modify messages, increasing their informative quality, the presence of private speech embedded in the messages, and the emergence of prior questions by the child in the listener role aimed at clarifying some aspect of the message. We found that the number of modified messages, the mean frequency of private speech in the messages, and the number of peer's questions all increase with age. Only in the case of the modified messages by the speaker did we find a triple interaction among age, use of private speech, and the presence of peer's questions. At 8.5 years, the presence of peer's questions and subsequent use of private speech appeared together for the majority of the modified messages. This was not the case at the ages 4.5 or 6.5. In line with Vygotsky's theses, private speech would play an important role to allow communicators to reflect on the quality of their communicative utterances, and to modify and improve them accordingly. In this process, the capacity to improve message accuracy by coordinating private speech with peer questioning clearly emerges with age.  相似文献

Materials at the Library of Congress (LC) by and about Russian émigrés take every form and are distributed throughout the library's many custodial divisions, classification schedules, catalogs, and Web pages. Identifying and locating these materials, whether in print, archival, or even digital collections, may require creative thinking and an understanding of the library's sometimes complex organization. The author attempts here to provide a preliminary overview of the library's Russian émigré collections and some guidance for beginning research on these collections. She includes examples as illustrations and inspiration for further research.  相似文献

From a systematic search of educational, psychological, and sociological literature, 18 studies of 5,831 school-aged students on the correlation of home environment and learning in eight countries over a 19-year period were selected. Correlations (the units of analysis) of intelligence, motivation, and achievement with indexes of parent stimulation of the student in the home are considerably higher than those with indexes of socioeconomic status (SES); specifically the medians (and ranges) of 92 simple correlations of home environment and learning are .37 (and .02 to .82) and of 62 multipleregression-weighted composites are .44 (and .23 to .81). Jackknifed regression estimates indicate that gender and SES of the sample affect the sizes of the correlations and suggest priorities for future primary investigations. The analyses suggest that ability and achievement are more closely linked to the sociopsychological environment and intellectual stimulation in the home than they are to parental socioeconomic status indicators such as occupation and amount of education.  相似文献

Calls for vigilance have been a recurrent theme in social justice education. Scholars making this call note that vigilance involves a continuous attentiveness, that it presumes some type of criticality, and that it is transformative. In this essay Barbara Applebaum expands upon some of these attributes and calls attention to three particular features of vigilance that, while they may be alluded to in the aforementioned discussions, are rarely made explicit. These three features are critique, staying in the anxiety of critique, and vulnerability. Using the lens of Judith Butler's recent work and the discussions that her work has provoked, Applebaum examines these three features of vigilance and demonstrates how they are crucial for white people interrogating their complicity in systemic racism. Finally, she discusses how the expanded three features of vigilance can offer guidance to one of the enormously thorny questions that arises in the social justice classroom.  相似文献
