A large literature has documented the influence of child care on young children's development, but few studies have examined low-income children in community care arrangements. Using data from Welfare, Children, and Families: A Three-City Study (N = 204), this study examined the influence of child care quality and the extent of care on low-income children's (ages 2-4 years) cognitive and socioemotional development over time. Higher levels of child care quality were modestly associated with improvements in children's socioemotional development, and extensive hours in child care were linked to increases in children's quantitative skills and decreases in behavior problems. Analyses suggest that child care quality may be particularly salient for subgroups of children from low-income families. 相似文献

New functions in the university often begin as satellites, marginal to the core of the academic disciplines and the faculty. With success they seek to institutionalize those functions sometimes by incorporating them into the faculty role pattern. This study examined the receptivity across a university faculty to the role changes associated with continuing education for established professionals. Working with mid-career practitioners may offer an unusual degree of intellectual stimulus and affinity to faculty members. Respondents evaluated the importance of a set of role behaviors, some traditional, some new. Application of multiple discriminant analysis to these ratings identified agreement on several basic values along with four subcultural groupings based on views of applied knowledge and the degree of relationship to an established profession. 相似文献

AbstractDialogic pedagogy is being promoted in science teacher education but the literature on dialogic pedagogy tends to focus on explicit voices, and so runs the risk of overlooking the important role that material objects often play in science education. In this paper we use the findings of a teacher survey and classroom case study to argue that there is a gap in the way that science teachers think about the role of materials and that this could be addressed by changes in the theory base of teacher training, augmenting the current constructivist and dialogic theory with the addition of new materialism in the form of Barad’s ‘Agential Realism’. Our findings suggests that science teachers do not regularly explicitly consider the relationship between the material resources they deploy and the dialogic learning taking place. We argue that science teacher training and professional development should pay more attention to the material-dialogic relationships in the learning that emerges in science classrooms. 相似文献

This paper demonstrates a formal statistical test that can be used to help researchers make decisions about alternative statistical
model specifications. This test is commonly used by researchers who would like to test whether adding new variables to a model
improves the model fit. However, we demonstrate that this formal test can also be employed when alternative representations
of variables or constructs are considered for inclusion in a regression. An empirical example is provided using information
from a widely cited US Department of Education report. Substantively, we find evidence that an alternative representation
of an important policy variable would have been a better fit to the data than the index that was used in the analysis conducted
in the report.
