We examined ethnicity and cultural orientation as predictors of parents' views of and involvement in children's education, using data gathered from the Latino (n = 74) and non‐Latino (17 White and 13 ethnic minority) parents of children in an elementary school's dual‐language program. Parents completed a questionnaire that assessed Latino and White American cultural orientations, importance of children's academic and social success, and self‐ and significant other involvement in children's education. Results indicated that Latino (and other ethnic minority) parents valued academic and social success equally and more strongly than did Whites and that Whites valued social success more strongly than academic success. Latinos also reported greater involvement of significant others. These differences were largely accounted for by cultural orientations. Educational practices that take into account differences in cultural orientations and the involvement of significant others thus seem more likely to improve academic outcomes than do efforts intended to promote the valuing of education. © 2010 Wiley Periodicals, Inc. 相似文献

The characterization of cell viability is a challenging task in applied biotechnology, as no clear definition of cell death exists. Cell death is accompanied with a change in the electrical properties of the membrane as well as the cell interior. Therefore, changes in the physiology of cells can be characterized by monitoring of their dielectric properties. We correlated the dielectric properties of industrially used mammalian cells, sedimented over interdigitated microelectrodes, to the AC signal response across the chip. The voltage waveforms across the electrodes were processed to obtain the circuit impedance, which was used to quantify the changes in cell viability. We observed an initial decrease in impedance, after which it remained nearly constant. The results were compared with data from the dye exclusion viability test, the cell specific oxygen uptake rate, and the online viable cell density data from capacitance probes. The microelectrode technique was found to be sensitive to physiological changes taking place inside the cells before their membrane integrity is compromised. Such accurate determination of the metabolic status during this initial period, which turned out to be less well captured in the dye exclusion tests, may be essential for several biotechnology operations. 相似文献

This meta-analysis synthesized 97 effect sizes extracted from 37 intervention studies for students with reading difficulties (RDs) in Grades 6 to 12 published between 1982 and 2021 to identify the overall impact of reading interventions and the moderating effects of intervention characteristics and study design characteristics. Random-effects robust variance estimation (RVE) was used to account for dependencies within studies. Overall, interventions designed to improve reading comprehension outcomes for adolescents with RDs were effective (g = 0.63). Meta-regression analyses identified several significant moderators that were associated with intervention efficacy, such as text content, duration of intervention, agent of intervention, status of student, type of dependent measure, and study quality. We provide study limitations as well as implications for research and practice. 相似文献

A blue‐ribbon panel convened by the National Council for Accreditation of Teacher Education (NCATE) concluded in 2010 that teacher education in the United States must be “turned upside down,” with practical experience at its center and academic content woven around the practical. It might seem that the new clinical model based on medical education, which has been adopted by eight states, would be well‐aligned with a Deweyan inquiry‐based pedagogy. Dewey himself recognized a paradox, however: preparation for the combination of rigor and flexibility needed for inquiry‐based pedagogical skills absolutely requires immersion in clinical settings, even as immersion in the teaching environment that prevails in U.S. public schools systematically socializes new teachers to a very different set of skills than those needed for this model of effective pedagogy. Recent scholarship by Kuhnian scholars provides practical guidance for an alternative understanding of how changes in practice occur and may be transmitted to future generations. 相似文献
