当前国际上开发了60多种认知诊断计量模型(Fu &; Li, 2007), 各种模型各具特点, 实际应用者应根据实际情况选用恰当的模型。本研究以属性层级关系为切入点, 采用Monte Carlo模拟的研究方法, 比较了属性层级关系正确及有误两种情况下, 当前国际上常用的五种认知诊断模型的性能, 以充分考察不同认知诊断模型对属性层级关系的依赖程度, 及属性层级关系的错误界定对各认知诊断模型诊断正确率的影响, 从而为实际运用者在认知诊断模型选用上提供借鉴和参考。 相似文献

This two-study series examined the effectiveness of self-management in increase compliance with parental requests. Three boys diagnosed with Autism Spectrum Disorder and their parents participated. The intervention involved self-monitoring combined with parent-delivered reinforcement. A multiple baseline design was used. The intervention was successful in increasing rates of compliance and reducing problem behavior in training and generalization settings with each participant. Social validity was high and treatment integrity data indicated that the intervention could be readily implemented by parents. Study 2 also provided evidence of a strong treatment effect for the self-management beyond a small effect for effective instructional delivery. 相似文献

We evaluated the effects of three different methods of denying access to requested high-preference activities on escalating problem behavior. Functional analysis and response class hierarchy (RCH) assessment results indicated that 4 topographies of problem behaviors displayed by a 13-year-old boy with high-functioning autism constituted an RCH maintained by positive (tangible) reinforcement. Identification of the RCH comprised the baseline phase, during which computer access was denied by saying "no" and providing an explanation for the restriction. Two alternative methods of saying "no" were then evaluated. These methods included (a) denying computer access while providing an opportunity to engage in an alternative preferred activity and (b) denying immediate computer access by arranging a contingency between completion of a low-preference task and subsequent computer access. Results indicated that a hierarchy of problem behavior may be identified in the context of denying access to a preferred activity and that it may be possible to prevent occurrences of escalating problem behavior by either presenting alternative options or arranging contingencies when saying "no" to a child's requests. 相似文献

Chinese values in Singapore: Traditional and modern 总被引:1,自引:0,他引:1

A series of three studies was conducted to test the internal structure of the Chinese value hierarchy (CVH) in Singapore. Study 1 identified the empirically best–fit model with six factors: Prudence, Industry, Civic–Harmony, Moral Development, Social Power and Moderation. Relative magnitudes and interfactor correlations suggested that these factors could be further grouped into two superordinate clusters: (i) The Modern factor, with significantly higher magnitude, consisted of Prudence, Industry, Civic–Harmony and Moral Development; and (ii) the Tradition factor, with lower magnitude, consisted of Social Power and Moderation. Study 2 surveyed university students with differential preference for language usages: English or Chinese. Both language groups were equally high on the Modern factor, but the Chinese–language–preferred group showed a significantly higher endorsement for the Tradition factor, Chinese Worldview (CWV) and Chinese Health Beliefs (CHB). Further convergent validation for the Modern and the Tradition factors was provided by investigating their correlations with traditional Chinese beliefs and practices for the two language groups separately. Study 3 tested generation differences in CVH. University participants (Self) were compared with their parents (Parents) and friends (Friends). There were no differences between Self and Friends on both the Modern and Tradition factors, CWV and individual differences of modernity. Parents and Self did not differ on individual differences of modernity. Parents, however, were higher on the Modern factor, the Tradition factor and CWV. Results were discussed to support the concept of 'multiple modernity' (Tu, 1900) in Asian societies, and the 'revised convergence hypothesis' proposed by Yang (1988). 相似文献

Christine Korsgaard claims that an agent is less than fully rational if she allows some attitude to inform her deliberation even though she cannot justify doing so. I argue that there is a middle way, which Korsgaard misses, between the claim that our attitudes neither need nor admit of rational assessment, on the one hand, and Korsgaard's claim that the attitudes which inform our deliberation always require justification, on the other: an agent needs reasons to opt out of her concerns – not reasons to opt into them or to stay in. As long as an agent has no good reason to abandon some concern of hers, she is reasonable to harbour it, and to allow it to inform her view of what reasons she has. A rational agent must therefore have the capacity to form higher-order attitudes toward her concerns; but rationality only requires that she exercise that capacity when she has some good reason to do so. 相似文献

本研究采用文献研究法,查阅了2000年以来中学语文和历史教案共303篇,对教案中教学目标的相关信息作点计数据处理,并进行卡方检验,结果表明:⒈近几年来我国中学语文和历史教学绝大多数采用布卢姆的教育目标分类取向;⒉两者的教学目标侧重于认知领域;⒊两者在认知和情感领域的目标要求学生达到的水平偏低,在动作技能领域的目标要求学生达到的水平偏高;⒋中学历史教学目标中对动作技能领域的理解有偏差;⒌两者在认知和情感领域的教学目标陈述时用词单一或含糊,而动作技能领域教学目标的陈述较清晰。研究结果提示,提高广大一线教师有关教学目标的分类理论及科学地运用教学目标的陈述技术仍有很长的路要走。 相似文献

Learning in High-Tech and Multimedia Environments 总被引:2,自引:0,他引:2
Roxana Moreno 《Current directions in psychological science》2006,15(2):63-67
ABSTRACT— When do high-tech environments promote learning? The goal of this article is to offer one answer to this question by examining the classic distinction between media and method, in terms of their roles in promoting learning with technology. To this end, I first propose a cognitive theory of learning with media, from which a set of instructional design principles are derived. Then I review research in which the relative learning contributions of method and media are investigated, and I offer final reflections for future research. 相似文献

In resurgence, conventionally a target response is trained and then extinguished while some alternative response is reinforced. In the most common procedure, when the latter is extinguished, the former resurges. The present experiments examined resurgence after two responses were trained sequentially and subsequently extinguished. In Experiments 1 and 2, keypecking to one key was trained and then extinguished as keypecking to a different key was trained then later extinguished. In both experiments, regardless of the spatial location of the different keys, the last‐trained response resurged before the first‐trained one. The results were replicated in Experiment 3 where reinforcement rate of the first‐trained response was four times that of the second‐trained response. The results in conjunction with earlier experiments suggest that resurgence occurs hierarchically, although whether more or less recently trained target responses resurge first or later may depend on both current and historical variables. The results also raise questions about the interpretation of responding on a control key that sometimes is included in resurgence experiments to isolate resurgence from extinction‐induced responding. 相似文献
