This article discusses contemporary American school stories that appear to advocate learning and literacy as a democratic good, but actually undermine democratic possibilities by teaching young readers to think of academic inquiry as a means to selfish, petty ends. Since “learning” and “literacy” are catchwords for educators dedicated to remedying neoliberal inequities, it is understandable why authors of school fiction such as Andrew Clements and Tommy Greenwald are celebrated by educators for foregrounding the exploits of bookish characters. Yet, as is shown, the narrative arcs in works such as Frindle by Clements and Charlie Joe Jackson’s Guide to Not Reading by Greenwald ultimately endorse the market consciousness, deregulation, and excessive individualism for which neoliberalism is known. Examining the ways in which these two novels intersect with ongoing debates over literacy standards, learning outcomes, and academic honesty, it is argued that the didactic-pedagogical imagination in contemporary American fiction for young people has a biased conception of student development and life preparedness, ideologically at odds with democratic curriculum provision.  相似文献

A method of using laser induced fluorescence(LIF)technique was applied to two-dimensional measurement of the liquid concentration distribution in the 250Y structured packing sheet. The experimental structured packing sheet was made of perspex so that the laser could pass through it. The visualization of the distribution of the liquid concentration in the structured packing sheet was realized. The calibration of the thickness and liquid concentration was carried out firstly and the regression formula I=kcd was acquired, in which concentration c and the liquid film thickness d were both considered. Then the liquid feed of uniform tracer(rhodamine)concentration entered the perspex structured packing from the top under different spraying densities. The corresponding thickness of liquid film on the packing was calculated. Finally, tracer(rhodamine)with a high concentration was injected only at one fixed point of the structured packing under different spraying densities of the liquid. With the known liquid film thickness, the concentration distribution of the tracer can be calculated inside the structured packing sheet.  相似文献

This article describes the establishment in fall 2002 of a School of Education Research Center designed to support faculty in increasing productivity and quality in research. Details are provided about center goals, services, staffing, space, resources, and logistics during the first year of operation. In addition, data are shared about faculty usage of the Center, the level of faculty satisfaction with center services in the first year, and initial increases in faculty productivity. The article concludes with plans for continued data collection to monitor the impact of the Center, a discussion of lessons learned at this point in the Center's development, and possibilities for the evolution of the Center. All authors are at the University of Colorado, Denver. Laura Goodwin, Ph.D., University of Colorado at Boulder, is Interim Associate Vice Chancellor for Faculty Affairs and continues to serve as a Faculty Research Associate. Elizabeth Kozleski, Ed.D., University of Northern Colorado, is the Associate Dean for Research in the School of Education. Lynn Rhodes, Ed.D., Indiana University, is the Dean of the School of Education. Rodney Muth, Ph.D., Claremont Graduate School, is a professor of Administrative Leadership and Policy Studies in the school and chaired the Research Center Advisory Board. Kim Kennedy White, M.A., University of Oregon, was the original School of Education Research Center Coordinator and was responsible for collecting most of the data included in this study.  相似文献

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.  相似文献
