Abstract In this paper we describe the particularities of Latin American museum visitors as learners through an exploratory study that took place at Universum, Museo de las Ciencias, a science museum located in Mexico City. The exploration of the learning experiences of Latin American family groups was carried out by means of a case study approach and from a socio‐cultural theory perspective. This inquiry of 20 family groups reveals that nuances of the concept of “family,” in the Mexican context, are important in studying family learning in museum settings. The prominent roles of the extended family and interactions within family groups are discussed as intrinsic traits of a family’s museum learning. In addition, the outcomes of this study highlight the impact that the Latin American notion of educación has on museum education and research, as it encompasses issues that relate to the perpetuation of socio‐cultural values, child‐rearing, and ultimately, cultural identity. 相似文献

Since the late 1800s library and information science (LIS) publications have discussed community assessment as a process for librarians to acknowledge the distinct needs and interests of their communities and respond by meeting those needs. The varied publications on the topic do not authorize any community assessment model or conceptual framework as the professional standard. This literature review examines community assessment publications, primarily in LIS. Instructional resources and publications provide a variety of suggestions for methods of conducting community assessments, while case studies illustrate the successes and challenges of various methods. Librarians must continue community engagement and advance cultural awareness in community assessment. 相似文献

School Context and Charter School Achievement: A Framework for Understanding the Performance “Black Box” 总被引:1,自引:1,他引:0
This article explores the relationship between charter school racial composition, school environments, and student achievement. We offer an original framework for understanding school context and its influence on schooling outcomes. We conclude that policymakers could better attend to the persistent educational inequality that has shaped U.S. schooling if when designing school choice plans they took account of student racial composition even in a postdesegregation environment. 相似文献

The dropout rate among Spanish university students is very high compared to the European mean, creating a pressing need for the introduction of policies and programmes aimed at increasing rates of persistence. In this article, we study this problem by combining students’ perceived learning outcomes with their dropout intentions, and we propose a research model that considers subjective factors that might impact this decision. The model is estimated for two degree courses: Business Administration and Nursing. The estimation method uses structural equations based on the partial least squares algorithm. This allows the construction of indices for the variables of interest, enabling us to make comparisons between courses and over time. To reduce dropout intentions, efforts need to be focused on obtaining better cognitive outcomes, as well as on achieving a higher level of student satisfaction with their university experience. 相似文献

Grades often decline during the high school transition, creating stress. The present research integrates the biopsychosocial model of challenge and threat with the implicit theories model to understand who shows maladaptive stress responses. A diary study measured declines in grades in the first few months of high school: salivary cortisol (N = 360 students, N = 3,045 observations) and daily stress appraisals (N = 499 students, N = 3,854 observations). Students who reported an entity theory of intelligence (i.e., the belief that intelligence is fixed) showed higher cortisol when grades were declining. Moreover, daily academic stressors showed a different lingering effect on the next day's cortisol for those with different implicit theories. Findings support a process model through which beliefs affect biological stress responses during difficult adolescent transitions. 相似文献

Research Findings: To extend findings that are mainly based on North American studies with English speakers, we studied 989 Chilean mothers from households of low socioeconomic status and their prekindergarten children, posing 2 questions: (a) Do mothers’ self-reported practices about literacy development predict early literacy outcomes over and above child characteristics and maternal education? (b) Do these maternal practices mediate the relation between maternal education and these child outcomes? Confirming previous studies, exposure to texts and non-present talk predicted vocabulary, and teaching practices predicted child code-related skills. Contrary to previous studies, exposure to texts also predicted child code-related skills. We also found that maternal practices partially mediated the relation between maternal education and early literacy skills. Practice or Policy: Findings suggest the need to target children before prekindergarten with interventions that increase the studied maternal practices and to do so in family, day care, and health care settings with special emphasis on families with incomplete elementary education. The broad effect of exposure to texts on early literacy outcomes and the low social value on reading in Chilean culture suggest that teacher preparation programs need to include ways to engage children in literature as a frequent experience. 相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow 总被引:1,自引:0,他引:1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors. 相似文献

Not every child seems equally susceptible to the same parental, educational, or environmental influences even if cognitive level is similar. This study is the first randomized controlled trial to apply the differential susceptibility paradigm to education in relation to children's genotype and early literacy skills. A randomized pretest–posttest control group design was used to examine the effects of the Intelligent Tutoring System Living Letters. Two intervention groups were created, 1 receiving feedback and 1 completing the program without feedback, and 1 control group. Carriers of the long variant of the dopamine D4 receptor gene (DRD4 7‐repeat) profited most from the computer program with positive feedback, whereas they performed at the lowest level of early literacy skills in the absence of such feedback. Our findings suggest that behind modest overall educational intervention effects a strong effect on a subgroup of susceptible children may be hidden. 相似文献

A Small‐Scale Randomized Efficacy Trial of the Identity Project: Promoting Adolescents’ Ethnic–Racial Identity Exploration and Resolution 下载免费PDF全文

Adolescents’ ethnic–racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small‐scale efficacy trial involved an ethnic–racially diverse sample of adolescents (N = 215; Mage = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group. Differences between conditions in ERI exploration at Time 2 were consistent with desired intervention effects; furthermore, higher levels of ERI exploration at Time 2 predicted increases in ERI resolution at Time 3 only for youth in the treatment condition. Findings provide preliminary evidence of program efficacy. 相似文献

This work is based on the assumption that if the classroom is a space in which manifestations of critical autonomous thinking appear systematically, then it promotes that same kind of thinking by the students, in other contexts. But what count as manifestations of critical autonomous thinking, and how can we observe them? As Robert Young's Habermasian work on indoctrination and conversational genres seemed a promising conceptual framework for understanding classroom situations in this respect, we took it as a starting point for exploring answers to these questions. Our exploration, both through fieldwork and theoretical reflection, led us to some findings, among which are (1) the existence of new genres which refine the conceptual categories originally formulated by Young; (2) that analysis of function is not enough, requiring also a contents dimension with which one can study what critical autonomous thinking is promoted about, in particular classroom situations; and (3) that classroom situations can be more contradictory and fragmented than presupposed by the very idea of genre. 相似文献
