Research Findings: Two longitudinal studies are reported examining the effects of full-time day care in Mapuche and non-Mapuche families in Chile. First, the Magellan-Leiden Childcare Study (MLCS) used a sample of 95 mothers with children younger than 1 year old (n = 36 in day care). Second, we partially cross-validated our results in a large and representative sample of 10,723 mothers and their children from the Chilean Encuesta Longitudinal de la Primera Infancia (Early Childhood Longitudinal Survey). In both studies, the quality of care for children provided at home was measured with the Home Observation for Measurement of the Environment. In the MLCS study, additional indicators of the mother–child relationship were measured. Day care was not negatively associated with the mother–child relationship and maternal sensitivity, compared to maternal care, or with the quality of the home environment. Positive changes in attachment security were found in Mapuche children who attended day care centers. Practice or Policy: We were able to confirm that type of care was not differentially associated with quality of the home environment. 相似文献
TACTICS (French and Spanish acronym standing for Collaborative Work and Learning in Science with Information and Communications Technologies) is an ongoing project aimed at investigating a distributed community of learning and practice in which information and communications technologies (ICT) take the role of collaborative tools to support social construction of knowledge. This community is composed of researchers, graduate students, and high-school teachers and their students, from six schools and four universities in Canada and Mexico. It set out in fall 2000 to develop a community around the general topic of integrating concepts in science school subjects. Once a prototype community is established, it can become a terrain where different aspects could be studied. Subsequently, researchers could gradually take a back seat allowing as well as ensuring the autonomy of the school members involved and, thereby, the viability of the learning community. The set up of the proposed prototype distributed science learning community was therefore an essential yet far from trivial first step. This paper discusses the process of setting up the community and the lessons learned. 相似文献
Research consistently shows that teaching behaviour is a highly-important indicator of learning environments. Based on a teacher effectiveness model with six observable teaching behaviour domains (safe learning climate, efficient classroom management, clarity of instruction, activating teaching, teaching–learning strategies, and differentiation), the present paper examines the psychometric quality of the My Teacher questionnaire for capturing student perceptions of teaching behaviour in the Spanish secondary-education context. Additionally, this study validated the model of teaching behaviour and student engagement and its relevance in Spain. 7114 students of 410 teachers attending 56 public and private Spanish schools constituted the sample. The six teaching behavioural dimensions model were confirmed in the Spanish context. Regarding student academic engagement, the presence of two domains (behavioural and emotional engagement) were confirmed. Furthermore, results of a multiple-group structural equation modeling path analysis, examining the relationship between teaching behaviour and student engagement across different teaching experiences, revealed differential effects of teaching behaviour influences on students’ engagement. The percentage of explained variance was larger for emotional engagement than for behavioural engagement. Furthermore, teachers’ teaching experience explained differences in the relationship between perceived teaching behaviour and engagement. Two domains (learning climate and activating teaching) appeared to be the two most-important teaching domains for students’ behavioural engagement while, for emotional engagement, the most important domains for student engagement were learning climate and teaching learning strategies.
There are many studies about the experiences of higher education students, but few analyse their representations of the governance and the management of their institutions. Our study will describe, analyse and compare students' representations of institutional evaluation at three institutions in Portugal and Brazil. Our results, based on an open questionnaire which sought to collect students' views on institutional evaluation, show that students' views are neither homogeneous nor do they simply reproduce the dominant external perspectives on the subject. A significant amount of students thought that evaluation is a legitimate exercise, resulting from a political decision, which is useful to improve the quality of universities and the relationship between students and academic staff. Some students also recognize that evaluation will lead to institutional comparisons, functioning as a mechanism of control, regulation, monitoring, and possibly of standardization. It is also noted to be ‘an impossibility’, since it can never comprehend the existing diversity of institutional performance. 相似文献

We solve the problem of petroleum products distribution through oil pipelines networks. This problem is modelled and solved using two techniques: A heuristic method like a multiobjective evolutionary algorithm and Mathematical Programming. In the multiobjective evolutionary algorithm, several objective functions are defined to express the goals of the solutions as well as the preferences among them. Some constraints are included as hard objective functions and some are evaluated through a … 相似文献
ABSTRACT The contextual, purpose-driven challenges facing schools and school systems across the world call for creative and innovative responses to revitalize school practices. The process of revitalization will require new thinking, new mindsets within an adaptive school culture and new leadership roles (formal and informal). Often the perception of leadership held within a school is that it is the province of the principal; however, if we move from a top-down model of leadership we can ulitize the capacity of others within to lead the learning. To enable this to happen, teacher leaders need to work with agency and principals need to nurture and grow their formal and informal leadership roles within the school. For many teachers, the question is how they can establish and commit to leadership roles and responsibilities within the school community while remaining in a teaching position. This case study examined the practices of teachers as they experienced leadership across three cross-cultural contexts: Colombia, Canada and Australia. It presents exemplars of teacher leadership in action and provides images of teacher leadership as enacted in addition to an understanding of the factors that were important in supporting their leadership actions. 相似文献
Co-assessment is a type of participatory assessment in which the teacher and student jointly discuss, negotiate and assess the student’s task or performance. Although the literature on co-assessment is scarce, some authors highlight the benefits for students of participating in co-assessment in higher education, including learning, improved communication, and greater assessment literacy. This study has a double objective: on the one hand, to analyse the strengths and limitations perceived by students participating in co-assessment practices; on the other hand, to explore the strengths, weaknesses, opportunities and threats perceived by professors participating in the experience. The study was developed in 8 class groups with the participation of 470 students and 4 teachers. The qualitative analysis of the data obtained from the questionnaires and focus groups indicates that the students acknowledged several strengths, among which learning from mistakes was prominent. Students also noted some limitations, particularly the lack of adjusted scoring. Professors offered another perspective that complemented the vision of their students, noting that co-assessment presents opportunities as well as risks that may jeopardise its implementation. 相似文献
AbstractLatino students now make up 1 in 4 public school students in the United States and are a rapidly growing population in nontraditional settlement areas. Yet -persistent racial and ethnic disparities in educational achievement and attainment are cause for grave concern, as high school graduation and postsecondary -education are increasingly necessary for success in a 21st-century knowledge economy. This essay discusses a major shift in demographics across the nation and the resulting urgent educational challenges. 相似文献
