谁曾见过风?你和我都不曾见过。但当树叶颤抖时,顿觉飘然风乍起。谁曾见过风?你和我都不曾见过。但当林木低头时,便是一阵风吹过。Who has seen the wind?Neither I nor you.But When the leaveshang trembling,The wind is passing through.Who has seen the wind?Neither you  相似文献

The present study was designed to explore the association between preschool academic skills and Grade 3 achievement among a sample of ethnically diverse children from low-income families. Data were collected from a sample of 1,442 low-income, ethnically diverse children in preschool and associated with Grade 3 achievement in reading and mathematics 4 years later. Mixed-effects modeling indicated that preschool skills significantly predicted Grade 3 achievement measures while controlling for various child-level factors and random school effects. While several preschool factors were predictive of Grade 3 achievement, writing/copying and counting/premathematics skills were consistently strong predictors of Grade 3 achievement across all measures and domains suggesting these are important foundational skills for academic success in midelementary school among low-income, ethnically diverse children. Findings also replicate studies demonstrating that writing plays an important role in learning and achievement. Findings have implications for early education policy and practice intended to support academic development among low-income, ethnically diverse children.  相似文献

This article investigates to what extent scholarships are unequally distributed among students in Germany and how these inequalities can be explained. Following sociological theory, the article argues that elites seek qualitative ways of distinguishing themselves in a mass higher education system. Using student surveys, we demonstrate that class effects cannot merely be explained with reference to class differences in academic achievement but that higher classes have better access to scholarships independent of earlier school performance. Class differences were particularly persistent when the intermediate classes were compared with higher classes with more education. These findings illustrate that social classes have different strategies when it comes to participating in higher education and suggest that information about and access to scholarships is important in gaining a class advantage.  相似文献

We describe the propagation of a technology-based educational innovation through its first 3 years of public use. The innovation studied is the Concept Warehouse (CW), a database-driven website developed to support the use of concept-based pedagogies. This tool was initially developed for instructors in undergraduate chemical engineering courses, but has spread to other disciplines as well. In this time, it has grown to over 650 registered instructors representing over 170 institutions. While this study is specific to a particular case, the intent of this article is to provide an exemplar of real-time propagation that informs other researchers and developers. We frame our analysis with Diffusion of Innovation Theory and use a design research methodology that focuses on communication channels, types of knowledge, and stages of the innovation-decision process. Data sources include usage records and survey responses which are analyzed with network diagrams and non-parametric statistics. We find that in comparison to mass media, interpersonal communications tended to result in higher proportions of how-to knowledge and implementation. Three types of opinion leaders were identified through user data and network diagrams. All played critical roles in the tool’s propagation, especially the project collaborators—opinion leaders who actively promoted the CW, in part, because it also propagates their own innovations. Finally, users with self-identified prior principles knowledge showed statistically significantly greater progress in gaining how-to knowledge, but no significant difference in progressing to the implementation stage of the innovation-decision process when compared to users without.  相似文献

Research that clearly demonstrates the negative effects of institutionalization, particularly for young children, has been critical for changing policy. However, actually putting science into action requires advocacy, persistence, and perseverance. Policy makers and advocates must be informed about the research and use it effectively. This paper proposes a number of key components for translating research into policy and programs: analyzing the situation, using evidence to build the case for action, developing policies, building program capacity in child welfare and early childhood development, creating a family‐based child welfare system, and developing a system of monitoring and accountability. Much of the knowledge in this paper comes from experiences, desk reviews, and case studies of successful practices. Research provides the basis, but moving research to practice depends on collaboration between researchers who understand the key policy perspectives and policy makers who understand the research.  相似文献

Instructors of sexual health courses in rural areas face unique challenges as they are often forced to use school-based prevention curricula field-tested in urban areas. Research has yet to consider what future sex educators’ regional expectations are for their profession and how those expectations might have an impact on the classroom. Drawing from interviews with 26 sex-educators-in-training, we find that future educators tended to expect that rural communities would be less diverse, more conservative, and less informed about sexual health matters, even though research demonstrates that today's rural communities inconsistently align with those perceptions.  相似文献
