This study examined the Maryland State Department of Education Breakthrough Center (BTC) engagement in a Baltimore City turnaround high school. Utilizing a case-study design and mixed-methods research, data were collected through interviews, informal observations, and review of administrative and achievement documents. Beginning in the 2011–2012 academic year, the BTC has been working in collaboration with school personnel to improve the educational experiences and academic achievement of students. School personnel recognized that the BTC has been responsive to teachers' requests and has exhibited a flexible approach building collaborative and nonevaluative relations. Administrative and achievement data also indicated improvement in school outcome measures during the past 3 years. Nevertheless, school faculty also identified important challenges of the BTC intervention, such as the relevance of this intervention for veteran teachers, the extent to which the needs of all student populations were met, and the sustainability of the intervention.  相似文献

A bstract .  The concept of development is currently under revision in education and psychology. In this essay, Eugene Matusov, Renée DePalma, and Stephanie Drye examine a traditional notion of development and provide an alternative sociocultural view. As educators working within a sociocultural approach to learning, development, and education, the authors see psychological phenomena as rooted in participation in sociocultural activities, practices, and communities. They critique how the traditional notion of development essentializes this process, assuming development to be independent of the observer. Using a case where a child of color develops a "sitting disability" within the institutional context of schooling, they illustrate the need for introducing a sociocultural notion of development, arguing that development is a social construction emerging in communities of practice and that it is necessary to consider the role of the observer in both defining and guiding this process in a professional discourse of cases.  相似文献

With permission from Childbirth Connection, the “Executive Summary” for the Listening to Mothers II survey is reprinted, here. The landmark Listening to Mothers I report, published in 2002, described the first national U.S. survey of women''s maternity experiences. It offered an unprecedented opportunity to understand attitudes, feelings, knowledge, use of obstetric practices, outcomes, and other dimensions of the maternity experience. Listening to Mothers II, a national survey of U.S. women who gave birth in 2005 that was published in 2006, continues to break new ground. Although continuing to document many core items measured in the first survey, the second survey includes much new content, exploring earlier topics in greater depth, as well as some new and timely topics.  相似文献

Many questions submitted to Collaborative Question Answering (CQA) sites have similar questions answered before. We propose a precise approach of automatically finding an answer to such questions by automatically identifying “equivalent” questions submitted and answered, in the past. Our method is based on automatically generating equivalent question patterns by grouping together questions that have previously obtained the same answers. The generated patterns are used as seed patterns to match more questions to extract large number of equivalent patterns by a new bootstrapping-based learning method. The resulting patterns can be applied to match a new question to an equivalent one that has already been answered, and thus suggest potential answers automatically. We experimented with this approach over a large collection of more than 200,000 real questions drawn from the Yahoo! Answers archive, automatically acquiring over 16,991 groups of equivalent question patterns. These patterns allow our method to obtain over 57% recall and over 54% precision on suggesting an answer automatically to new questions, significantly improving over baseline methods.  相似文献
