Economic stress, parenting, and child adjustment in Mexican American and European American families 总被引:1,自引:0,他引:1

To assess the impact of economic hardship on 111 European American and 167 Mexican American families and their 5th-grade (M age=11.4 years) children, a family stress model was evaluated. Structural equation analyses revealed that economic hardship was linked to indexes of economic pressure that were related to depressive symptoms for mothers and fathers of both ethnicities. Depressive symptoms were linked to marital problems and hostile parenting. Paternal hostile parenting was related to child adjustment problems for European Americans, whereas marital problems were linked to child adjustment problems for Mexican Americans. Maternal acculturation was associated with both higher marital problems and lower hostile parenting. The utility of the model for describing the effects of economic hardship in Mexican Americans is noted. 相似文献

While proof is central to mathematics, difficulties in the teaching and learning of proof are well-recognised internationally. Within the research literature, a number of theoretical frameworks relating to the teaching of different aspects of proof and proving are evident. In our work, we are focusing on secondary school students learning the structure of deductive proofs and, in this paper, we propose a theoretical framework based on this aspect of proof education. In our framework, we capture students’ understanding of the structure of deductive proofs in terms of three levels of increasing sophistication: Pre-structural, Partial-structural, and Holistic-structural, with the Partial-structural level further divided into two sub-levels: Elemental and Relational. In this paper, we apply the framework to data from our classroom research in which secondary school students (aged 14) tackled a series of lessons that provided an introduction to proof problems involving congruent triangles. Using data from the transcribed lessons, we focus in particular on students who displayed the tendency to accept a proof that contained logical circularity. From the perspective of our framework, we illustrate what we argue are two independent aspects of Relational understanding of the Partial-structural level, those of universal instantiation and hypothetical syllogism, and contend that accepting logical circularity can be an indicator of lack of understanding of syllogism. These findings can inform how teaching approaches might be improved so that students develop a more secure understanding of deductive proofs and proving in geometry. 相似文献

Teachers' failure to use the microcomputer‐based laboratory (MBL) more widely may be a result of not recognizing its capacity to transform laboratory activities. This research aimed to increase understanding of how MBL activities designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 15 students. Dyads addressed 10 tasks in thermal physics using a predict–observe–explain format. Data sources included video and audio recordings of students and teacher during four 70‐minute sessions, students' computer data and written notes, semistructured student interviews, and the teacher's journal. Analysis of students' discourse identified many instances in which students' initial understandings of thermal physics were mediated in multiple ways by the screen display. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities that will likely catalyze student construction of understanding. © 2004 Wiley Periodicals, Inc.

Education and ethnicity cannot be discussed without taking language into account. This paper will argue that any discussion of ethnic minorities cannot ignore the question of language, nor can any discussion of human rights ignore the question of language rights. Unfortunately, in today's globalised world, governments and minorities are faced with conflicting pressures: on the one hand, for the development and use of education in a global/international language; on the other for the use and development of mother tongue, local or indigenous languages in education. Language complexity and ethnic plurality were largely brought about as a result of the creation of nation–states, which were spread around the world as a result of European colonialism. European languages and formal education systems were used as a means of political and economic control. The legacy that was left by the colonial powers has complicated ethnic relations and has frequently led to conflict. While there is now greater recognition of the importance of language both for economic and educational development, as well as for human rights, the forces of globalisation are leading towards uniformity in the languages used, in culture and even in education. They are working against the development of language rights for smaller groups. We are witnessing a sharp decline in the number of languages spoken. Only those languages which are numerically, economically and politically strong are likely to survive. As a result many linguistic and ethnic groups are in danger of being further marginalised. This paper will illustrate this thesis both historically and from several contemporary societies, showing how certain policies have exacerbated ethnic conflict while others are seeking to promote harmony and reconciliation. Why this should be so will be explored. 相似文献

Many primary teachers have a limited understanding of science concepts. A recent Australian government review of science teacher education strongly recommended that this problem be addressed in preservice and post‐initial teacher education programs. This paper outlines some approaches that might satisfy this recommendation. Course structure and design are initially considered. Specific techniques are then described which revolve around a constructivist approach to teaming science concepts. Although the importance of science processes is still acknowledged, it is implied that significant time needs to be devoted to reflecting upon and sharing one's own perceptions of science concepts. Some exemplar professional development courses and materials which also address the teacher's own science knowledge are considered briefly. The suggestions and examples draw heavily upon approaches taken by British teacher educators who have had to confront this issue directly because of the nature of their science syllabus. 相似文献

The Nobel Prize in Economics was awarded in 2002 for work on judgment and decision-making tasks that are the operational measures of rational thought in cognitive science. Because assessments of intelligence (and similar tests of cognitive ability) are taken to be the quintessence of good thinking, it might be thought that such measures would serve as proxies for the assessment of rational thought. It is important to understand why such an assumption would be misplaced. It is often not recognized that rationality and intelligence (as traditionally defined) are two different things conceptually and empirically. Distinguishing between rationality and intelligence helps explain how people can be, at the same time, intelligent and irrational. Thus, individual differences in the cognitive skills that underlie rational thinking must be studied in their own right because intelligence tests do not explicitly assess rational thinking. In this article, I describe how my research group has worked to develop the first prototype of a comprehensive test of rational thought (the Comprehensive Assessment of Rational Thinking). 相似文献

In this article, we focus on three aspects of students' prior experiences of learning: evoked conceptions of learning, evoked motivation and evoked self-efficacy. We show how, for a first-year undergraduate population, these three aspects of evoked prior experience relate to students' approaches to learning and their perceptions of the learning environment as well as to their previous schooling, their gender and the broad discipline area in which they are studying. In doing so, we confirm that evoked prior experiences are distinct and measurable and can be used to better understand the ways in which students experience learning in higher education. 相似文献

We explored the effect of stroke removal from Chinese characters on eye movements during reading to examine the role of stroke
encoding in character identification. Experimental sentences were comprised of characters with different proportions of strokes
removed (15, 30, and 50%), and different types of strokes removed (beginning, ending, and strokes that ensured the configuration
of the character was retained). Reading times, number of fixations and regression measures all showed that Chinese characters
with 15% of strokes removed were as easy to read as Chinese characters without any strokes removed. However, when 30%, or
more of a character’s strokes were removed, reading characters with their configuration retained was easiest, characters with
ending strokes removed were more difficult, whilst characters with beginning strokes removed were most difficult to read.
The results strongly suggest that not all strokes within a character have equal status during character identification, and
a flexible stroke encoding system must underlie successful character identification during Chinese reading. 相似文献
