自我决定能力被认为是残障学生课程和学习指导的核心组成要素之一,培养自我决定能力的发展是促进残障学生在毕业后获得更好发展的一种教学策略。相关研究美国已成体系而国内始露头角。本研究阅读美国残障人士自我决定相关文献并进行以下五个方面的分析:自我决定概念起源与发展、相关政策法规、理论模型、教学模型、教育教学实践。根据文献分析美国自我决定研究的发展趋势,并思考在我国促进残障人士自我决定能力发展的可能性与必要性,且提出四点建议。 相似文献

采用经典的A:B:C:D范式,设计两类难度不同的图片任务,依据关系-表征复杂性模型从等级复杂性和水平复杂性角度分析任务难度.在此基础上,选取5~9岁115名儿童探讨两类任务上类比推理的特点和发展趋势.表明:(1)儿童类比推理呈现多样化特点,主要有:充分意义上掌握了类比推理、部分完成了类比推理、位置关系类比推理、不能类比推理和不确定情况类比推理,其中部分完成了类比推理是复杂任务上所特有的.(2)简单、复杂两类任务上,随着年龄增长,5-9岁儿童充分意义上掌握类比推理的人次比例不断上升,不能类比推理的人次比例不断下降.此外,复杂任务上,随年龄增长,部分完成类比任务的人次比例降低.结果表明,在简单任务上,前运算阶段儿童已具备了类比推理能力;但在复杂任务上,儿童到了具体运算阶段才具备类比推理能力. 相似文献

在使用项目反应理论进行量尺化的语境下, 参数标定方法是垂直量尺化结果的一个至关重要的影响因素。目前的参数标定研究就部分标定方法的相对性能获得了较一致的结果, 就如何实现更佳量尺化也提出了很多新的标定方法。除了在既有框架内继续探索, 以形成完整的研究体系, 未来的研究应结合相关学科, 在深入了解学业增长的性质的基础上探究标定方法的性能, 并应考察特定的标定方法和特定的研究条件、量尺化语境之间的最佳匹配关系。 相似文献

以北京市某中学和某小学11~14岁之间294名学生为被试, 其中超常儿童131人, 普通儿童163人。采用推箱子任务, 结合横向比较和纵向追踪数据, 从认知能力、元认知能力和认知效率三个维度来考察超常儿童与普通儿童问题解决能力的发展差异。结果发现超常儿童在问题解决能力的三个维度上均优于普通儿童, 两类儿童问题解决能力的发展模式不一致:超常儿童的问题解决能力发展先快后慢, 快速发展期在11~12岁半之间; 普通儿童的问题解决能力发展先慢后快, 快速发展期在12岁半~14岁之间。超常儿童与普通儿童的问题解决能力差异随年龄增大逐渐减小。 相似文献

Prospective longitudinal studies have shown strong predictions from conduct disorders (CDs) in childhood to antisocial personality disorder (ASPD) and violence in adults. However, little is known of the childhood antecedents of serious violence nor whether these may vary depending on the context in which the violence occurs. In this study, 54 men aged 21-40 years serving prison sentences for violent crime were assessed. Standardized interviews of ASPD and violence were conducted independently of interviews covering retrospective recall of childhood psychiatric disorders and adverse experiences. Analyses of the predictors of overall violence suggested a pathway involving childhood CD and adult ASPD associated with interparental discord, and an additional pathway associated with experiencing interparental violence in childhood. Different results were however obtained when account was taken of the context of the violence. The CD-ASPD pathway was associated with social violence, but not with partner violence. Partner violence was predicted by retrospective reports of having been exposed to interparental violence during childhood but not by reports of childhood CD or adult ASPD. Thus developmental pathways to serious violence may be different depending on the social domain in which the violence occurs. 相似文献

Research has not systematically assessed and validated preferences for staff in adults with developmental disabilities. Three adults with developmental disabilities (aged 32 to 43 years) identified preferred and nonpreferred staff using verbal and pictorial preference assessments. During break-point analyses with progressive-ratio schedules, all 3 had higher break points when working for positive social interaction with their preferred staff mamber than with their nonpreferred staff member. 相似文献

Biological Sensitivity to Context 总被引:2,自引:0,他引:2
ABSTRACT— Conventional views suggest that exaggerated biological reactivity to stress is a harmful vestige of an evolutionary past in which threats to survival were more prevalent and severe. Recent evidence, however, indicates that effects of high reactivity on behavior and health are bivalent rather than univalent in character, exerting both risk-augmenting and risk-protective effects depending on the context. These observations suggest that heightened stress reactivity may reflect increased biological sensitivity to context, with potential for negative health effects under conditions of adversity and for positive effects under conditions of support. From an evolutionary perspective, the developmental plasticity of the stress-response systems, along with their structured, context-dependent effects, suggests that variation in these systems has been adaptively patterned to increase the capacity of children to match their stress-response profiles to anticipated developmental environments. Taken together, these theoretical perspectives generate a novel hypothesis: that there is a curvilinear, U-shaped relation between early exposures to adversity and the development of stress-reactive profiles, with high-reactivity phenotypes disproportionately emerging within both highly stressful and highly protected early social environments. 相似文献
