The present study explores practitioner perceptions of and observations about the adoptive parent, birth parent, and adoptee interactions that regulate open adoption relationships. Grounded in family systems theory, practitioner interviews (N = 19) were analyzed to understand the degree to which open adoption shapes the family system as well as the opportunities, challenges, and considerations experienced by individuals in open adoption. Findings reveal that open adoption relationships consist of numerous complex relationships. This complexity generates significant opportunities for connection. At the same time, the complexity of the system generates challenges. Social networking provides costs and rewards that require consideration on an individual basis. Findings offer implications for the utility of family systems theory in illuminating diverse family construction as well as open adoption communication research.  相似文献

The potential of individualization to transform learning that new technology makes possible has generated wide interest. We ask here whether individualization has been exploited to its maximum advantage. We explore its potential to provide individualized scaffolding at the meta-level of students’ reflection on their own thinking as they engaged in inquiry activity to support their reasoning about a multivariable causal system – a capability central to scientific thinking and higher-order thinking more broadly. In Study 1, middle-school pairs’ self-paced inquiry was individually guided by an adult who prompted them to question their assertions and strategies. Study 2 investigated how such scaffolding might be automated to provide individualization at scale. Delayed posttests for both studies involving new scenarios showed that gains in both inquiry and multivariable causal inference skills transferred to new content. Delayed far-transfer assessments showed that the intervention achieved its learning goals most effectively when an adult worked with a pair of students, compared to students working as a whole class (Study 1); students also learned effectively with an automated agent, but only when a human adult was also involved (Study 2). Implications are considered for developing and deploying technology that individualizes and supports self-directed, reflective meta-level thinking and learning, while remaining mindful of human social context.  相似文献

用进化策略求解多目标优岱问题时,为了保证Pareto前沿的多样性,该文提出了基于拥挤度和分散度的多样性处理方法,在分析基于拥挤距离处理多样性的基础上引入了拥挤度和分散度的概念,当两个个体具有相同的拥挤度时,通过其分散度来判断哪个个体更拥挤,这样能更好地保证解在Pareto前沿的多样性.仿真实验表明,该算法能更好地维持Pareto前沿的多样性。  相似文献

Disproportionality in disciplinary actions for certain racial groups has been well documented for several decades. In an effort to support all students, specifically those who are culturally and linguistically diverse, many have called for adopting a multitiered system of support framework that is considerate of student culture and school context. This framework applies to supporting students’ learning and behavior across settings, particularly in the classroom. To bridge existing gaps between theory and practice, this empirical study sought to evaluate whether teachers who self‐assessed their own use of culturally and contextually relevant practices would implement a class‐wide behavior plan with high levels of implementation fidelity. Results indicated that teachers who engaged in self‐assessment and training did implement the plan with high levels of implementation fidelity, particularly when given performance feedback. Additionally, students tended to display slightly higher rates of academic engagement upon consistent implementation of the plan.  相似文献

当前差分进化算法研究主要集中在常规种群上,对小种群差分进化(DE)算法的研究较少。小种群差分进化算法因种群规模小,存在多样性降低过快的问题。因此提出一种基于控制参数双峰分布的小种群差分进化算法(BiMDE)。该算法采用基于柯西双峰分布的参数调节机制处理变异缩放因子 F 和交叉概率因子 CR,并对缩放因子 F 进行矢量化设定。将 BiMDE 算法在函数集 CEC2014 上进行测试,并与 5 种最新的小种群差分进化算法进行比较。结果表明,BiMDE 算法在求解精度、收敛速度以及多样性保持上具有较大优势。  相似文献

In this study, we employ a curricular conceptual lens of the particular to explore the experience of multicultural education from the perspective of an immigrant student, Raj. Using a school-based narrative inquiry approach, we learn about Raj's experiences at the intersections of immigration and settlement, adaptation and assimilation, English-language acquisition, unemployment, poverty, family violence, and family relocation. We employ Dewey's [(1938). Experience and education. New York: Simon & Schuster] theory of experience, Connelly and Clandinin's [(1988). Teachers as curriculum planners: Narratives of experience. New York: Teachers College Press, Columbia] understanding of curriculum as experience, and Schwab's [(1969). The practical: A language for curriculum. School Review, 78, 1–23] theory of the particular as theoretical frameworks upon which to examine and analyze interactions and events.  相似文献

本从诱导效应、超共轭效应以及极化作用等几方面对烷基的电子效应作了浅析,认为烷基的诱导效应是吸电子的,其超共轭效应对正负电荷都具有稳定作用。据此,对某些基础问题的解释进行了讨论。  相似文献
