This paper explores the dynamics of purposeful leadership and parental involvement, two central components of effective schools. The results of four cases studies are presented that consider the ways in which principals work with parents in schools that have a shared, consistent mission. The case studies reveal that principal‐parent interactions are the result of unique processes in each school and are negotiated and institutionalized over time. 相似文献

西部民族地区的稳定关系全国经济发展及人民生活,维护社会公正、和谐应成为政府工作的中心。由于社会稳定属于社会管理职能,本文从社会管理方面的风险出发,通过问卷调查法制定了民族地区社会稳定风险评估体系,并运用层次分析法,对西部民族地区社会稳定的风险进行测定。结果显示政治风险在二级指标中权重最大,政治风险中比重大的是腐败及对政策的满意度。最后,有针对性地提出了维护社会稳定的预警机制。 相似文献

Our study investigates perspectives of mathematics teacher educators related to the usage of their mathematical knowledge
in teaching “Methods of Teaching Elementary Mathematics” courses. Five mathematics teacher educators, all with experience
in teaching methods courses for prospective elementary school teachers, participated in this study. In a clinical interview
setting, the participants described where and how, in their teaching of elementary methods courses, they had an opportunity
to use their advanced mathematical knowledge and provided examples of such opportunities or situations. We outline five apparently
different viewpoints and then turn to the similar concerns that were expressed by the participants. In conclusion, we connect
the individual perspectives by situating them in the context of unifying themes, both theoretical and practical. 相似文献

The emergent perspective (Yackel and Cobb, 1996) is a powerful theory for describing cognitive development within classrooms.
Yackel and Cobb have shown that the formation of social and sociomathematical norms, and opportunities for learning are intertwined.
The present study is an attempt to extend the range of application of the emergent perspective to middle high school classrooms.
The learning environments we consider are rich in the sense that (i) the tasks in which students are engaged are open-ended
problem-situations (ii) the activities around the tasks are multiphased, consisting of small group collaboration on problem
solving, reporting and reflection in a classroom forum with the teacher (iii) the tools used are multi-representational software.
We identify here some practices rooted in such rich environments from which several sociomathematical norms stemmed. The present
study shows that socio-mathematical norms do not rise from verbal interactions only, but also from computer manipulations
as communicative non-verbal actions.

This article is a systematic reflection on a sequence of episodes related to teaching probability. Our central claim is that
reducing problems to a consideration of the sample space, which consists of equiprobable outcomes, may not be in accord with
learners’ initial ways of reasoning. We suggest a “desirable pedagogical approach” in which the solution builds on the set
of outcomes as identified by learners and serves as a bridge towards mathematical convention. To explore prospective high
school mathematics teachers’ ideas related to addressing a potential learner’s mistake and their reactions towards the suggested
approach, we presented them with two tasks. In Task I, participants (n = 30) were asked to suggest a pedagogical remedy to a frequent mistake found in dealing with a standard probability problem,
whereas in Task II, they were asked to solve a probabilistic problem, which they had not encountered previously. We discuss
participants’ mathematical solutions to Task II in reference to their pedagogical approaches to Task I. The presented disparity
serves in extending the convincing power of the suggested pedagogical approach. 相似文献

We present a view of knowledge construction processes, focusing on partially correct constructs. Motivated by unexpected and
seemingly inconsistent quantitative data based on the written reports of students working on an elementary probability task,
we analyze in detail the knowledge construction processes of a representative student. We show how the nested epistemic actions
model for abstraction in context facilitates following the emergence of a learner’s partially correct constructs (PaCCs).
These PaCCs provide added insight into processes of knowledge construction. They are also used in order to analyze and explain
students’ thinking in situations where some of the students’ answers were unexpected in light of their earlier answers or
inconsistent with earlier answers. In particular, PaCCs are explanatory tools for correct answers based on (partially) faulty
knowledge and for wrong answers based on largely correct knowledge. 相似文献

Maternal Working Models of Attachment, Marital Adjustment, and the Parent-Child Relationship 总被引:2,自引:0,他引:2
This study examined the connection between maternal working models, marital adjustment, and the parent-child relationship. Subjects were 45 mothers who were observed in problem-solving interactions with their 16–62-month-old children ( M = 33 months). Mothers also completed the Attachment Q-set, the Adult Attachment Interview, and a marital adjustment scale. As predicted, maternal working models were related to the quality of mother-child interactions and child security, and there was a significant relation between marital adjustment and child security. Maternal working models and marital adjustment were also associated interactively with child behavior and child security. Among children of insecure mothers, child security scores were higher when mothers reported high (vs. low) marital adjustment. No relation between child security scores and mothers' marital adjustment was found among children of secure mothers. These results suggest that maternal working models influence parenting and child adjustment well beyond infancy, to which period the few existing studies of adult attachment have been restricted. The results also suggest that interactions between maternal working models and the marital adjustment on child behavior and attachment security need to be more closely examined. 相似文献
