Transforming engagement: a case study of building intrinsic motivation in a child with autism 下载免费PDF全文
Jackie Dearden Anne Emerson Tom Lewis Rebecca Papp 《British Journal of Special Education》2017,44(1):8-25
This longitudinal case study of a 10‐year‐old girl with autism and severe communication impairment measures the impact of the MORE (Means, Opportunities, Reasons and Expectations) approach to enhancing engagement and communication. Through detailed observation of video data over a period of 28 months, engagement behaviours including interaction with adults and following adult directions increased, while resistant behaviours such as kicking, hitting and pushing adults away decreased. Fluctuation between different ‘states’ demonstrated that the frequency and duration of engagement was influenced by the MORE approach and an emphasis on developing intrinsic motivation. In order to enable further efficacy research, core features of the intervention and the changes in engagement over time are described. 相似文献

The analysis of covariance (ANCOVA) is a useful statistical procedure that incorporates covariate features into the adjustment of treatment effects. The consequences of omitted prognostic covariates on the statistical inferences of ANCOVA are well documented in the literature. However, the corresponding influence on sample-size calculations for precise interval estimation has not been fully evaluated. This article aims to explicate the deficiency of approximate methods for ignoring the stochastic nature of covariate variables and to present exact approaches for precise interval estimation of treatment contrasts under the assumption that the covariate variables have a joint multinormal distribution. The desired precision of a confidence interval is assessed with respect to the control of expected half-width and to the assurance probability of interval half-width within a designated value. Numerical appraisals show that the suggested approaches outperform the approximate formulas for the two precision considerations. 相似文献

The aim of the present study was to examine the spelling development of Greek‐speaking children in the early school grades. Although Greek orthography is regular for reading, it is much less transparent as far as spelling is concerned. Spelling development was investigated using a word spelling task designed to explore the effects of word length, familiarity and spelling regularity. One hundred and fifty normally developing primary school children living in Cyprus took part in the study. Results suggest that the children employed both phonological and lexical strategies in spelling Greek words. Results indicated that sub‐lexical procedures were more marked for younger children, whereas lexical processing was employed more widely by older children. The findings are interpreted in terms of stage developmental models. 相似文献

Analysis of variance is one of the most frequently used statistical analyses in the behavioral, educational, and social sciences, and special attention has been paid to the selection and use of an appropriate effect size measure of association in analysis of variance. This article presents the sample size procedures for precise interval estimation of eta-squared and partial eta-squared in fixed-effects analysis of variance designs. The desired precision of a confidence interval is assessed with respect to (a) the control of expected width and (b) the tolerance probability of interval width within a designated value. In addition, sample size calculations for standardized contrasts of treatment effects and corresponding partial strength of association effect sizes are also considered. 相似文献

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control (ILC) is proposed in this paper. The developed analog ILC method and the high-gain property tracker design methodology are first combined to significantly reduce learning epochs and overcome the initial condition shift problem and discontinuous reference input in the traditional ILC. Besides, the proposed ILC improves the transient response and decreases the rate of weighting matrices Q to R under the traditional linear quadratic tracker design. First, the off-line observer/Kalman filter identification (OKID) is used to determine the appropriate (low-) order system parameters and state estimator for the physical system with unknown system equation, so that the model-based PD-type ILC can be implemented for practical applications. Then, to improve the transient response and decrease the control effort, the proportional difference type (PD-type) ILC algorithm is combined with the high-gain property linear quadratic tracker (LQT) design to construct the high performance tracker for the model-based sampled-data systems. Furthermore, the discrete-time version high performance tracker design for the unknown stochastic sampled-data system via the iterative learning control method is proposed in this paper based on the Euler method and the digital redesign approach. Finally, some examples are given for illustrating the effectiveness of the proposed method. 相似文献

This paper offers an overview, both internationally and with a particular concentration on the UK, of how the profession‐orientated discipline of publishing studies (PS) is accommodated and established within those universities where it is offered. It presents a combination of data, gained from a survey of professionals teaching PS, desk research into courses of PS in the UK, and from Heidi and HESA. The findings offer information on the size of the field, the location, the employability of graduates and associated staffing and research support structures. While of interest to publishing studies per se, it should also be relevant to those working within other profession‐orientated disciplines; to those considering the employability of graduating students; and to those considering the value of postgraduate studies. 相似文献

This paper explores the implementation of formative assessment through the ‘autism lens’ in order to analyse why the process can be exclusionary for some learners on the autism spectrum. The central thesis of the paper is that, where teachers have no understanding of the autism learning style, they are likely to revert to a normative, ‘majoritarian’ construction of learning. Two problems may flow from this. First, majoritarian assumptions about learning could dominate the inferential process that is the foundation stone of formative assessment. This could lead teachers to mis-read what is going on inside the heads of learners on the autism spectrum, and cause them to make partial and inaccurate inferences about their learning. Second, majoritarian assumptions may also inform the interactive process that underpins formative assessment. Social interaction can be challenging for learners on the autism spectrum and can limit or exclude their participation unless sensitive modifications are made to the social and communication environment. The case is, therefore, made for teacher awareness of a ‘minoritarian’ perspective that foregrounds knowledge and understanding of the autism learning style. Arguably, this knowledge and understanding could enable teachers to adapt the formative assessment process so that it is more effective and inclusive for this group of learners. 相似文献
