This longitudinal study used latent growth curve modeling to investigate English literacy development in a sample of Spanish-speaking language minority students from third through eighth grade. This study also compared the sample’s literacy development to the entire population of California students using state standardized test data. Second, this study examined the contributions of a variety of bilingual measures of kindergarten letter knowledge, phonological awareness, word reading, and vocabulary to literacy development. Results demonstrated the present sample scored below average in literacy compared to the overall population of California students across years, but made slight gains to narrow the achievement gap. The greatest gains were obtained between fourth and fifth grade, but plateaued thereafter. Results concerning the second research questions showed that the third grade literacy intercept was predicted by kindergarten English letter knowledge, Spanish onset, Spanish word reading, and English vocabulary. However, English literacy development through eighth grade was only predicted by kindergarten English and Spanish vocabulary. Findings support arguments for educational efforts to target oral language instruction for these students in early elementary and instruction in both languages may provide the greatest benefit. Instructional implications are discussed.  相似文献

Developmentalists are often interested in understanding change processes, and growth models are the most common analytic tool for examining such processes. Nonlinear growth curves are especially valuable to developmentalists because the defining characteristics of the growth process such as initial levels, rates of change during growth spurts, and asymptotic levels can be estimated. A variety of growth models are described beginning with the linear growth model and moving to nonlinear models of varying complexity. A detailed discussion of nonlinear models is provided, highlighting the added insights into complex developmental processes associated with their use. A collection of growth models are fit to repeated measures of height from participants of the Berkeley Growth and Guidance Studies from early childhood through adulthood.  相似文献

[童话大意]一个农场主有一个忠诚的仆人,这个仆人辛辛苦苦地给他干了三年的活,而他却没有付给仆人任何工钱。后来仆人打定主意,想出去看看外面的世界,不再干下去了。他找到农场主说:"我为你勤勤恳恳地做了这么久的事,相信你会根据我的劳动付给我应得的工钱。"农场主是一个极其吝惜的守财奴,只拿出三便士给他,也就是一年一便士的工钱。可怜的仆人对钱没有多少概念,  相似文献

Although a large number of different organisations offer various forest education programmes within Germany, specific information (i.e., sectoral and programme content and provision at a state level) is lacking. This study used a survey of all 61 forest education organisations (43 respondents) in the state of North Rhine‐Westphalia, Germany, to evaluate its forest education sector, with a specific focus on the organisations, demand for its services, forest educational programmes and framework conditions. Input from expert interviews was also used to develop recommendations. The study indicates that, especially with children as the main target group, many non‐formal programmes are offered to support the formal environmental education sector and to promote leisure activities in the forest. Yet, despite a high demand for forest education, low personnel resources restrict the number of visits and activities, principally owing to limited financial resource. We also discuss the provision of innovative new educational programmes and supplementary services, combined with increased quality management, that could be beneficial to the future development of the sector in NRW.  相似文献

In this simulation study, we explored the effect of introducing covariates to a growth mixture model when covariates were also generated by a mixture model. We varied the association between the latent classes underlying the growth trajectories and the covariates, the degree of separation between the latent classes underlying the covariates, the number of covariates included, and amount of missing data in the growth data. We found that adding covariates to the growth mixture model generally hurt class recovery except where the latent classes underlying the growth trajectories and the covariates were the same or very strongly associated, and there was a large degree of separation between the classes underlying the covariates. We found that when covariates were introduced, entropy might no longer be an accurate indicator of the distinctiveness of the growth trajectory classes.  相似文献

An important goal of any sexuality education program is to support youth and young adults to develop a positive self-image and develop competence and confidence in skills needed to express sexuality and develop positive relationships. For youth and young adults with disabilities, sexuality education is offered far less often than for their same aged peers without disabilities. This article describes a three-step process for developing specially designed instruction in sexuality education using principles of instructional design to meet the unique needs of students with disabilities.  相似文献

The purposes of this study were to examine: 1) the potential muscle-specific differences in voluntary electromechanical delay (EMD) and relaxation electromechanical delay (R-EMD), and 2) the effects of intensity on EMD and R-EMD during step incremental isometric muscle actions from 10 to 100% maximal voluntary isometric contraction (MVIC). EMD and R-EMD measures were calculated from the simultaneous assessments of electromyography, mechanomyography, and force production from the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) during step isometric muscle actions. There were no differences between the VL, VM, and RF for the voluntary EMDE-M (onsets of the electromyographic to mechanomyographic signals), EMDM-F (onsets the mechanomyographic to force production), or EMDE-F (onsets of the electromyographic signal to force production) as well as R-EMDE-M (cessation of electromyographic to mechanomyographic signal), R-EMDM-F (cessation of mechanomyographic signal to force cessation), or R-EMDE-F (cessation of electromyorgraphic signal to force cessation) at any intensity. There were decreases in all EMD and R-EMD measures with increases in intensity. The relative contributions from EMDE-M and EMDM-F to EMDE-F as well as R-EMDE-M and R-EMDM-F to R-EMDE-F remained similar across all intensities. The superficial muscles of the quadriceps femoris shared similar EMD and R-EMD measurements.  相似文献

Recent political initiatives in the UK have sought to increase the role of supporters in the governance of football clubs. The Labour Party included in their 2015 general election manifesto proposals to give supporters a statutory right to representation on the board of directors of their club. In Scotland, amendments to the Community Empowerment (Scotland) Act (2015) have provided Scottish Ministers with a framework to develop legislation relating to supporter involvement in governance. To date, however, there has been limited research on supporter representation, and the practicability of legislation giving fans the right to a seat in the boardroom has not been investigated. The purpose of this paper is to address that gap in the literature. In-depth interviews were conducted with 10 directors of Scottish football clubs. Findings show that such legislation would be imprudent given the inherent difficulty of the role and the potential disruption to board dynamics.  相似文献
