This article documents the efforts by Mexican Americans to challenge school segregation in Arizona in the first half of the twentieth century. As in Texas and California, although state law never formally mandated the segregation of Mexican American students, school districts in Arizona often established separate “Mexican Schools” for Mexican American students. While districts argued that segregation was necessary because of students' poor English skills, the segregation of Mexican American students in Arizona's public schools was not an isolated practice but occurred in tandem with other discriminatory practices that restricted the social rights of Mexican Americans, many of whom were American citizens. However, Mexican Americans challenged segregation in the courts. Notably, in Gonzales v. Sheely, a case heard in the United States District Court of Arizona in 1950, Judge Dave Ling declared segregation unconstitutional over three years before the Supreme Court's historic decision in Brown v. Board (1954). 相似文献
Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms. What effect the creation of such contexts would have on very young children remains unclear. Using multilevel methods and data on 2,966 children in 704 prekindergarten classrooms, this study explores the relationship between socioeconomic classroom composition and children's social and cognitive development. The results indicate positive associations between the mean socioeconomic status (SES) of the class and children's receptive language, expressive language, and mathematics learning, regardless of children's own sociodemographic backgrounds and the characteristics of their classrooms. However, the analyses indicate no association between the development of social competence and class mean SES. Practice or Policy: The links between classroom SES and language and mathematics development were comparable in size to those associated with instructional quality and even children's own SES. Neither structural nor instructional characteristics of prekindergarten classrooms explained these relationships, suggesting the possibility of direct peer effects. The findings indicate that the composition of children's classrooms should be considered an important aspect of preschool quality. 相似文献
This paper describes the Texas A&M University (TAMU) Libraries' new and innovative approach to monograph collection development using a re-engineered internal funding structure and a process that reflects the needs and goals of the library and its users. The paper discusses the goals of the new fund structure, the experience of implementing it, and the results after one year in use. 相似文献
This paper is about the interaction between policy and practice, and about how competing policies contributed to a paradoxical
tension within that interaction in one school. Within a paradigm of educational renewal, the Singapore Ministry of Education
(MOE) has initiated a number of policies designed to give schools autonomy in designing and implementing programmes to achieve
optimal educational outcomes for its students. Among these are READ! Singapore, Teach Less, Learn More and the School Excellence
Model. In this context, we review an MOE initiated Extensive Reading (ER) programme in one school. Despite such innovative
policies, Dewey Secondary School’s [The names of the school and individuals have been changed to protect their privacy.] pedagogical
and literacy practices continue to be largely influenced by other dominant features of Singapore’s and the school’s own educational
culture—an exam-oriented focus that prioritises outcome and skill-based pedagogy and the school’s historical practice of restricting
literacies. Competing policies as interpreted by the school and diverse stakeholders result in a morphed ER programme—an adaptation
of a reading programme that reflects the programme intent overtly but one that collides at other times, and as a result, is
pulled in different directions. The story is, thus, one of ‘policies of promise and practices of limit’. 相似文献
The primary aims of this study were twofold: (a) to describe average change in the written narrative performance of second grade students from the fall and spring of the school year and (b) examine patterns of individual growth to test for Matthew effects. Participants included 299 children in second grade. Microstructural measures were derived from students’ written narratives including: number of different words (NDW), total number of words (TNW), and accuracy of spelling and grammar. Significant increases in NDW, TNW, and spelling accuracy were evidenced from fall to spring. Students averaged 55 total words in the fall and averaged 69 words in the spring, with a statistically significant increase of 14 words t(299)?=?8.4, p?<?.0001). The variance in TNW from fall to spring increased from Var?=?791 to Var?=?1005, which was a significant increase and the correlation of initial Fall TNW and growth in TNW was also significant (r?=?0.39). Additionally, results from a two-level hierarchical linear model with students nested within teachers indicated that initial level of TNW predicted the change in TNW from fall to spring, with higher levels of initial TNW being related to larger gains in TNW. Significant predictors of Matthew effects included teacher or classroom and free/reduced lunch eligibility. Written personal narrative measures are sensitive to developmental change across a school year. Evidence of Matthew effects in lexical productivity suggests additional support may be warranted to ameliorate gaps in writing achievement.
The author discusses how pursuing a rhetoric of science has consequences for both our understanding of science and our practice of rhetorical analysis. From a rhetorical perspective, science becomes a persuasive enterprise continuous with other persuasive practices in a culture. And rhetoric itself requires enrichment in three areas to become a better instrument of analysis for scientific texts; it needs to incorporate early modern dialectic, a more flexible stylistics, and an appreciation of the role of visualization in scientific argument. 相似文献
