Parents’ and teachers’ beliefs about children’s school readiness in a high-need community 总被引:1,自引:0,他引:1

This study compared the beliefs of preschool teachers, kindergarten teachers, and parents in one mostly Hispanic and Black high-need urban school district to learn their views of what children should know and be able to do at kindergarten entry. Beliefs regarding the importance of 12 school readiness “resources” were assessed with the CARES survey designed for this study. Parents held remarkably similar beliefs, regardless of ethnicity or education. Parents and teachers also agreed that children must be healthy and socially competent, and be able to comply with teacher authority, although parents rated this latter resource higher. However, parents rated all classroom-related readiness resources as more important than teachers did. They believed it was necessary for a child to be able to communicate in English and to have basic knowledge and skills, which was more important than a child’s approach to learning. Preschool teachers also believed that knowledge was more important than kindergarten teachers did. Directions for further research and implications for policy and practice are discussed. 相似文献

The work-set algorithm to automatically convert a bibliographic database into a Functional Requirements for Bibliographic Records (FRBR) structure has been developed and operated. However, in case the authority control is not properly performed as in Korean catalogs, it is impossible to FRBRize using only the automechanism. In such a case, a visual check must accompany the process; unfortunately, this requires extensive time and cost. Thus, in this case, it is desirable to cluster work-sets for a large-scale bibliographic database like a union catalog and to share the resulting work-sets with local libraries. To that end, this paper presents a method for extracting work-sets from the Korean union catalog using a semi-automatic mechanism. Additionally, it proposes methods to allow local libraries to apply the FRBR to their own OPAC using work-sets that result from the union catalog. 相似文献

In its late stage, Alzheimer's disease results in progressive muscle weakness in the arms and legs. The aim of this study was to determine whether mice expressing the skeletal muscle-specific mutant PS2 gene (a model of Alzheimer's disease) are a useful experimental system to study the protective effect of exercise on A beta-42 reduction, improvement of behavioural function and changes in metabolic parameters. With this aim in mind, the transgenic mice were subjected to treadmill exercise for 3 months. The results showed that in transgenic mice, but not in normal mice, treadmill exercise resulted in a reduction of A beta-42 deposits and an improvement in behavioural function, thereby restoring normal concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglyceride. Thus, exercise may represent a practical therapeutic strategy for use with human patients with Alzheimer's disease. 相似文献

A two part study investigated any relationship between student achievement and textbook content as well as any impact of a national project's recommendations on textbook content. First, analyses of student responses to biological items on the 1977 National Assessment of Educational Progress's survey of science showed a direct, linear relationship between achievement level and concept emphasis in biology textbooks. Second, a comparison between biology textbooks, published a decade apart, indicated significant changes in the degree of emphasis placed on 10 commonly accepted conceptual areas. Closer examination revealed that change in the amount of emphasis in one conceptual area, Growth and Development, was responsible for the significant difference found. Generally, the recommendations of the biology project were not reflected in the newer textbooks. 相似文献

The presence of nuisance dimensionality is a potential threat to the accuracy of results for tests calibrated using a measurement model such as a factor analytic model or an item response theory model. This article describes a mixture group bifactor model to account for the nuisance dimensionality due to a testlet structure as well as the dimensionality due to differences in patterns of responses. The model can be used for testing whether or not an item functions differently across latent groups in addition to investigating the differential effect of local dependency among items within a testlet. An example is presented comparing test speededness results from a conventional factor mixture model, which ignores the testlet structure, with results from the mixture group bifactor model. Results suggested the 2 models treated the data somewhat differently. Analysis of the item response patterns indicated that the 2-class mixture bifactor model tended to categorize omissions as indicating speededness. With the mixture group bifactor model, more local dependency was present in the speeded than in the nonspeeded class. Evidence from a simulation study indicated the Bayesian estimation method used in this study for the mixture group bifactor model can successfully recover generated model parameters for 1- to 3-group models for tests containing testlets. 相似文献

The main purpose of the current study is to validate the framework of knowledge management (KM) capabilities created by Gold (Towards a theory of organizational knowledge management capabilities. Doctoral dissertation, University of North Carolina, Chapel Hill) 2001) in a study of South Korean companies. However, the original framework did not provide a thorough explanation of the effect of incentives, which motivate and encourage the knowledge management process. In this study, the modified framework that includes incentives in the knowledge infrastructure capability was tested. Moreover, since there is a weak linkage between KM and organizational performance, this study used empirical evidence to identify the relationship between KM capabilities (KMC) and four perspectives of organizational performance. Since structural equation modeling (SEM) is mostly used to describe causal relationships among unobserved (latent) and observed variables, this study used SEM procedures to determine whether there were any structural relationships between knowledge management capabilities and four perspectives of organizational performance. Moreover, the SEM procedure is “a statistical test to find whether a model fits a set of data, whether it matches a theoretical expectation” (Vogt, Dictionary of statistics & methodology. Sage Publications Inc., Thousand Oaks, CA, p 135, 2005). Therefore, this study also used SEM procedures to test a hypothesized model that had a good fit indicates that the model adequately describes the sample data. This study assumed that knowledge management capabilities could be divided into two types: knowledge infrastructure and process capabilities. The original hypothesized model showed that there was a positive relationship between knowledge management capabilities and organizational performance, but the overall model fit was insufficient to be accepted, because knowledge infrastructure and process capabilities were highly correlated. This study proposed two alternative models to find the best fit and found that knowledge infrastructure and process capabilities should be combined under the higher-order latent variable as subordinate latent variables. Lastly, there was a positive relationship between KMC and organizational performance. This study might not be free from common method bias to some degrees. It would be better to divide participants into two groups to respond to either the knowledge management capabilities survey or the organizational performance survey and to investigate the correlation between them. There are two main contributions for the field of knowledge management. First, this study attempted to integrate the fragmented literature of knowledge management into a holistic view and develop a framework for knowledge management. Moreover, this study found that there is a strong and positive relationship between KM infrastructure and process, which could refer that, to improve organizational performance, an organization should support KM processes, as well as build decent KM infrastructure. The results of this study would help KM practitioners to advocate the importance of KM to top managements. 相似文献
