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

The response strategies of culturally deprived children as a function of race, sex, and grade level were investigated. A 2x2x3 balanced factorial design was used with twenty children at each grade level (kindergarten, first grade, second grade) . A test situation allowed children to make choices for each of five pairs of stimuli in a tray before receiving reinforcement for the “correct” choice. Chi-square analysis indicated that eleven of the twelve groups were using strategies in their choices at a rate greater than would be expected by chance alone. The groups differed by grade level in the number of times specific strategies were selected, although total number of strategies used did not differ across grade level, race, and sex. Constant strategies were used more often by kindergarten children while alternating strategies were utilized more often by second grade children. 相似文献

A Model of Homework's Influence on the Performance Evaluations of Elementary School Students 总被引:1,自引:0,他引:1
Harris Cooper Kristina Jackson Barbara Nye James J. Lindsay 《Journal of Experimental Education》2013,81(2):181-199
This study was the first to test a model of the influence of homework on classroom performance using a sample of elementary school students. A total of 28 teachers in Grades 2 and 4 took part in the study, along with 428 students and parents. The authors used structural equation modeling to examine relationships among variables. Student norms were positively related to the elimination of distractions from homework by parents. Positive student norms, higher student ability, and positive parent attitudes toward homework were all related to greater parent facilitation. Student's attitude toward homework was unrelated to home and community factors but was related positively to parent attitudes toward homework. Classroom grades were unrelated to student's attitude toward homework but were predicted by how much homework the student completed (even after the use of homework in grading was controlled), by student ability, and by the amount of parent facilitation. More generally, parent facilitation was an important mediator of the relation between student norms, student ability, and parent attitudes toward homework, and the outcome of classroom grades. 相似文献

Two thousand and sixty‐five 11‐year‐olds in their first term at secondary school were given a variety of attitude and achievement tests. Overall both girls and boys had positive attitudes to science but there were substantial sex differences‐‐boys were much keener than girls to learn about physical science, and girls were keener than boys to learn about nature study and human biology. Boys had much greater experience than girls of tinkering activities, but girls had more experience of biological science activities. Boys were much more likely than girls to see science as a masculine preserve. At this age attitudes to science were virtually unrelated to achievement in science‐ and technology‐related areas. One important exception to this is that girls who saw science as masculine tended to perform worse on the cognitive tests. 相似文献

This paper argues that the logic of neoliberal choice policy is typically blind to considerations of space and place, but inevitably impacts on rural and remote locations in the way that middle-class professionals view the opportunities available in their local educational markets. The paper considers the value of middle-class professionals’ educational capitals in regional communities and their problematic distribution, given that class fraction’s particular investment in choice strategies to ensure their children’s future. It then profiles the educational market in six communities along a transect between a major regional centre and a remote ‘outback’ town, using publicly available data from the Australian Government’s My School website. Comparison of the local markets shows how educational outcomes are distributed across the local markets and how dimensions of ‘choice’ thin out over the transect. Interview data offer insights into how professional families in these localities engage selectively with these local educational markets or plan to transcend them. The discussion reflects on the growing importance of educational choices as a marker of place in the competition between localities to attract and retain professionals to staff vital human services in their communities. 相似文献
