Development of decoding,reading comprehension,vocabulary and spelling during the elementary school years 总被引：1，自引：0，他引：1
The goal of this study was (1) to investigate the development of decoding(efficiency), reading comprehension, vocabulary and spelling during theelementary school years and (2) to determine the differences between poor,average and good performers with regard to the development of theseskills. Twice each year two standardized tests for each skill wereadministered. For two successive periods, one of the tests for each skill wasthe same. To describe the development in terms of a latent variable evolvingacross grades, the structured-means version of the structural equationmodel was used. The growth was expressed in terms of effect size. Withrespect to the first question, clear seasonal effects were found for readingcomprehension, vocabulary and spelling, while the seasonal effect fordecoding efficiency was restricted to the early grades. Progress tended tobe greater from fall to spring than from spring to fall. For decodingefficiency, and to a lesser degree for vocabulary and spelling, growthshowed a declining trend across grades. For reading comprehension, theprogress in grade 2 was lower than the progress in grade 3, but progresswas declining across higher grades. With respect to the second question,it appeared that initially low performers on reading comprehension,vocabulary and spelling tended to show a greater progress, especially inperiods where the largest amount of instruction was given. Although it wasfound that the low, medium and high ability groups remain in the sameorder, as far as their means are concerned, these findings do not confirmthe existence of a Matthew effect for reading comprehension, vocabularyand spelling. For decoding efficiency no clear differential effect could befound: the gap between the poor and good performers did not widen overtime for this skill. 相似文献

The primary goal of this article is to demonstrate the close relationship between 2 classes of dynamic models in psychological research: latent change score models and continuous time models. The secondary goal is to point out some differences. We begin with a brief review of both approaches, before demonstrating how the 2 methods are mathematically and conceptually related. It will be shown that most commonly used latent change score models are related to continuous time models by the difference equation approximation to the differential equation. One way in which the 2 approaches differ is the treatment of time. Whereas there are theoretical and practical restrictions regarding observation time points and intervals in latent change score models, no such limitations exist in continuous time models. We illustrate our arguments with three simulated data sets using a univariate and bivariate model with equal and unequal time intervals. As a by-product of this comparison, we discuss the use of phantom and definition variables to account for varying time intervals in latent change score models. We end with a reanalysis of the Bradway–McArdle longitudinal study on intellectual abilities (used before by McArdle & Hamagami, 2004) by means of the proportional change score model and the dual change score model in discrete and continuous time. 相似文献

ABSTRACTThis article discusses a public service review and redesign that resulted in a blended service desk combining reference and circulation functions, staffed by nonlibrarians. The redesign implements a number of organizational structures that encourage service excellence, as found in the business literature and in examples of nonlibrary organizations that excel in customer service. The article identifies key organizational structures that have been shown to support or hinder good service and discusses the process of implementing these structures in practice and the results of an assessment process designed around determining success. 相似文献

This paper reports on the effects of art education in secondary schools on the cultural participation of Dutch students 10–20 years after leaving school. We draw our conclusion from a sample survey among 1034 students from 31 schools, half of whom took art as a subject of examination. Art examination subjects were more often chosen by students who were already active in the arts, come from culturally active families, and who more often chose languages and other humanities in their examination package. However, in spite of their affiliation with art prior to choosing an examination package, training in the arts during secondary school was found to add to their participation in cultural activities ten to twenty years later. The effects are restricted to the same art discipline as the art lessons attended, and apply to both receptive [enjoying art of artists] and productive [producing art] cultural participation. 相似文献

This article has 3 objectives that build on each other. First, we demonstrate how to obtain maximum likelihood estimates for dynamic factor models (the direct autoregressive factor score model) with arbitrary T and N by means of structural equation modeling (SEM) and compare the approach to existing methods. Second, we go beyond standard time series analysis (T large and N = 1) and conventional SEM (N large and T = 1 or small) by integrating both approaches. The resulting combined model offers a variety of new modeling options including a direct test of the ergodicity hypothesis, according to which the factorial structure of an individual observed at many time points is identical to the factorial structure of a group of individuals observed at a single point in time. Third, we illustrate the flexibility of SEM time series modeling by extending the approach to account for complex error structures. We end with a discussion of current limitations and future applications of SEM-based time series modeling for arbitrary T and N. 相似文献

The first purpose of this study was to determine to what degree infant teachers and therapists in Dutch therapeutic toddler classes perceive job stress. Another purpose was to identify the sources of job stress. Further, this study examined whether infant teachers, physical, occupational and speech therapists have to cope with different degrees of job stress and, finally, the influence of staff characteristics on the degree of job stress was investigated. Sixty-two infant teachers and 88 therapists working in therapeutic toddler classes completed a questionnaire for job stress. Most job stress was perceived to be a result of lack of non-contact time. Nine sources of job stress were identified. The four disciplines responded differently to the sources of stress. Regression analysis showed profession to be the strongest predictor of job stress. 相似文献
