This article describes the results of a comprehensive review of the research literature from 2000 to 2011 evaluating the effects of early care and education practices on the developmental outcomes of dual language learners (DLLs) from birth through 5 years of age. Across 25 studies that met inclusion criteria, study samples consisted primarily of Latino or Spanish-speaking children 3–5 years of age enrolled in center-based programs. The analysis focused on features of the early education programs and practices (intensity and language of instruction) and research methods (sampling, research designs) in relation to child outcomes for the various types of research interventions evaluated in these studies (center-based programs, professional development, curricula, and instructional strategies). On the basis of a few large-scale scientifically sound studies, the review found at least some evidence to suggest that DLLs benefitted from attending widely available, well regulated programs such as Head Start and public pre-k, particularly with respect to improving language and literacy skills. However, because the extant research has not systematically accounted for the separate effects of language of instruction versus type of intervention, very little can be concluded about how these factors contribute to the positive main effects of these interventions.  相似文献

After students acquire a skill, mastery often requires them to choose to engage in assigned academic activities (e.g., independent seatwork, and homework). Although students may be more likely to choose to work on partially completed assignments than on new assignments, the partial assignment completion (PAC) effect may not be very powerful. The current studies were designed to replicate previous research and determine whether the amount of sunk effort was related to PAC effect strength. Together, these studies (1) provide the only current replication of PAC effect; (2) support previous research, which suggests that the PAC effect is not very powerful; and (3) extend the theoretical research on PAC effects by showing that sunk effort did not influence PAC effect strength. Discussion focuses on implications for educators and directions for future theoretical research designed to identify the causal mechanism responsible for the PAC effect.  相似文献

ABSTRACT

This study assesses acquisitions budget allocation for sustainable support of Indigenous Studies (IS) and the challenge of addressing the needs of an emergent subject area. A survey of collections librarians provided context for library allocation practices of other Canadian institutions offering IS programs. An analysis of titles purchased before and after creating an IS subject fund was performed; results reveal that there was an increase in the number of IS titles purchased annually after the fund was created. A defined subject fund allowed flexibility beyond conventional library collections structures to address the unique needs of IS as an academic discipline.  相似文献

A brief 15-item version of the California School Climate Scale (Brief-CSCS) is presented to fill a need for a measure that could be used for periodic monitoring of school personnel's general perception of the climate of their school campus. From a sample of 81,261 California school personnel, random subsamples of 2,400 teachers and 2,400 administrators were used in the analyses. Confirmatory factor analyses supported a model in which general school climate was a second-order latent factor composed of 2 first-order latent traits, organizational supports and relational supports. Measurement invariance of factor loadings for teachers and administrators was found. Additional analyses revealed that administrators held more positive perceptions of school climate than teachers, with this difference increasing from primary through high school. The implications for these findings for educational research and policy reform are outlined.  相似文献

In an attempt to better prepare future teachers to fight against social injustice, support their culturally and linguistically diverse students and wrestle with social and educational complexities around the globe, many education programs have increased the number of study abroad programs and international service learning projects. In this qualitative study, we explored seven preservice teachers’ experiences related to humanizing pedagogy after participating in a study abroad program combined with an international service-learning project in a South African rural community. Analyzing multiple data sources such as interviews and reflective journals, we discovered that the preservice teachers grappled with the political, social, economic, and educational differences they encountered during the international project and wrestled with conflicting ideas and beliefs about poverty and language. They identified their relationships with students as catalysts to address these educational issues and their need to reverse systemic inequities. They built caring relationships with students in the community and developed additive perspectives the focused on the students’ community cultural capital. The preservice teachers expressed deep critical reflection and a desire to promote a more fully human educational world where students have the opportunities to enact their agency, their creativity, and their language and culture.  相似文献
