Pathways from maternal tobacco, marijuana, stress, and anger in pregnancy to infant reactivity and regulation (RR) at 9 months of infant age were examined in a low‐income, diverse sample beginning in the first trimester of pregnancy, with fetal growth and postnatal stress/anger as potential mediators, and infant sex as a moderator. Participants were 247 dyads (173 substance‐exposed infants). There were no direct effects of prenatal risk on RR and no moderation by sex. However, there were significant indirect effects on RR via poor fetal growth and higher postnatal anger. The study adds to the sparse literature on joint effects of tobacco and marijuana, and highlights the role of fetal growth and maternal anger as important pathways from prenatal risk to infant RR.  相似文献

Differences in preservice elementary school teachers' perceptions between divisibility by two, or 'evenness' and divisibility by another number have been observed. This led to an inquiry into participants' understanding of the parity of the whole numbers. The results reveal that the equivalence of the number properties of being 'even' and being 'divisible by two' is not taken for granted. Rather, the parity is often perceived as a function of the last digit of the number. The extent of this perception is investigated. Some pedagogical approaches are considered.  相似文献

This article presents findings of a survey aimed at assessing the attitudes of faculty towards the absorption of immigrant students from the former Soviet Union. Data were collected from 33 lecturers in four colleges for the training of technicians and practical engineers in Israel. Responses range along a continuum between the view condoning assimilation (model 1) and the view advocating a gradual process of integration (model 2). These are pre‐existing models of sociological attitude towards immigrant absorption distinguished by Eisikovitz and Beck (1991, Studies in Education, 55/56, pp. 33‐50). According to model 1, all students should be granted equal attention and immigrant students should not be given special treatment. Model 2 recognizes the special status of the immigrant student and the intrinsic problems that accompany this status and, accordingly, the need to find appropriate solutions. Although there is general agreement regarding the main difficulties faced by the immigrants (namely, language problems, financial problems and cultural adjustment), most of the respondents seem to be closer to the perception expressed by model 1 and recommend that the academic requirements, teaching methods, timetable and curriculum be the same for the immigrants as for the veteran Israeli students. Nevertheless, attitudes conforming to model 2 were also expressed as revealed in the recommendation that immigrant students be offered special assistance in preparatory frameworks which should include courses to help acquaint them with the realities of Israeli society, and that they be provided with maintenance grants, textbooks, tutoring, etc. In general, different elements are adopted from each model in accordance with the special needs and circumstances of the immigrant population enrolled in the college.  相似文献

In this paper we examine typical difficulties involved in solving a combinatorial problem, and demonstrate them throughout the solution of the Problem of the misaddressed letters. We focus on difficulties of two sorts: Those which stem from the fact that a combinatorial problem is usually an infinite set of problems, and others which are involved in finding a systematic approach to their solution.  相似文献

Children with intellectual disabilities often struggle with handwriting, but there is very little research to inform intervention approaches. In this study, we developed a teaching manual based on Handwriting Without Tears®, a comprehensive handwriting programme designed for typically developing children. Three children with intellectual disabilities participated in the study and received handwriting instruction based on the manual three times a week over a 32‐week period. Our aims were to explore whether Handwriting Without Tears® can be used as a comprehensive handwriting curriculum for children with intellectual disabilities and to evaluate improvement in handwriting skills. We found that the intervention was successfully incorporated into small group teaching sessions within the child's regular classroom, and that all three children made improvements. Our data show promising results and support the need for larger evaluation studies.  相似文献

What makes a counterexample exemplary?   总被引:1,自引:1,他引:0  
In this paper we describe two episodes of instructional interaction, in which examples are used in order to help students face their misconceptions. We introduce the notions of pivotal example and bridging example and highlight their role in creating and resolving a cognitive conflict. We suggest that the convincing power of counterexamples depends on the extent to which they are in accord with individuals’ example spaces.  相似文献

We present a story of a teacher educator’s response to a situation of contingency and describe how her experience enhanced her personal mathematical knowledge and influenced her teaching. In our analysis, we attend to different levels of awareness that support a teacher educator’s work and illuminate the qualities of a teacher educator’s knowledge, in particular, knowledge at the mathematical horizon.  相似文献

美国档案学学者马特·马里恩以教科书式的方式呈现了口述历史工作从访谈、到数据储存、再到用户获取的全过程,从档案编目理论的角度对口述历史编目工作进行了系统性梳理.《口述历史编目手册》与实际操作紧密结合,对我国的口述历史编目工作具有借鉴意义,但是就图书馆的实践层面来看,来自社会媒体、编目外包、“问题意识”缺乏等带来的多重压力下,该手册的本土化应用有待进一步探讨.  相似文献
