This study evaluated the representations of nature of science (NOS) in U.S. state science standards, and examined the changes in these representations from documents advanced in the 1980s through 2016. Drawing from the consensus perspective on NOS and prior studies focusing on the analysis of textual content, documents were inspected for 10 target NOS aspects: the empirical, tentative, inferential, creative, theory-driven, and social NOS, in addition to the myth of “The Scientific Method,” the nature of scientific theories and laws, and the social and cultural embeddedness of science. Ninety-eight state documents from 48 states were analyzed and multiple editions were collected from 34 states. Additionally, relevant materials from the Next Generation Science Standards (NGSS) were assessed for their coverage of the same NOS aspects. Collected materials were scored as whole documents, including over 11,000 pages of text in total, on each target aspect, which reflected the treatment (naïve vs. informed) of NOS in text and the manner of presentation (explicit vs. implicit). Overall, surprisingly, state standards documents have improved very little with respect to their NOS coverage over the last 30 years. NOS standards documents remain silent on a majority of key aspects of NOS, and the number of aspects showing explicit, informed representations has held constant. The NGSS performed well compared to many contemporary documents, but they failed to address all target NOS aspects in a desirable manner. Further analysis raised concerns with the degree that states fully adopt and disseminate standards in manner consistent with the NGSS despite stated intentions, which may negatively impact NOS coverage in instructional resources and classroom enactments. To improve NOS representations in standards, recognizing the role these documents play in shaping instructional materials and teaching in the science classroom, exemplars from analyzed materials were highlighted with informed and explicit representations of multiple aspects. 相似文献

The purpose of this study was to examine the amount of time spent actively engaged in reading sounds, words, and connected text for students at‐risk for reading difficulties in the first formal grade of reading instruction, kindergarten. Observational data of 109 kindergarten students at high‐risk for later reading difficulties were collected during general education reading instruction across the school year. Findings revealed students read orally for just over 1 minute during their reading instruction with approximately equal time spent reading sounds, words, or connected text. Implications of these results for early reading instruction and intervention for students at‐risk for reading difficulties or disabilities are presented. 相似文献

Two-generation human capital programs seek to promote the education of parents and children simultaneously. This study examines relations between family participation in CareerAdvance, which recruits parents of Head Start children into a workforce training program, and children’s Head Start attendance. The sample included 293 children (on average 4 years old) and their parents. After one semester, CareerAdvance children demonstrated higher rates of attendance and lower rates of absence and chronic absence (missing 10% or more of school days) than matched comparison children. These associations were similar across a range of high- and low-risk subgroups at baseline. These findings are discussed in terms of the implications of a family systems approach for improving children’s Head Start attendance. 相似文献

National shortages of math and science teachers have led to a variety of strategies and programs to attract second career
professionals into teaching. This qualitative study explores the development of professional teaching identities in six STEM
career changers in a post-baccalaureate pre-service teacher credential program in California. Findings suggest the career
changers relied upon skills developed in their previous careers to navigate through a new profession; however, returning to
the life of a student again was difficult. Additionally, the career changers in this study valued interacting with their traditional
aged peers in the program as these relationships were beneficial to their own socialization into teaching as they developed
their teacher identities. 相似文献

Children raised without a biological father in the household have earlier average ages of first sexual intercourse than children raised in father-present households. Competing theoretical perspectives have attributed this either to effects of father absence on socialization and physical maturation or to nonrandom selection of children predisposed for early sexual intercourse into father-absent households. Genetically informative analyses of the children of sister dyads ( N = 1,382, aged 14–21 years) support the selection hypothesis: This association seems attributable to confounded risks, most likely genetic in origin, which correlated both with likelihood of father absence and early sexual behavior. This holds implications for environmental theories of maturation and suggests that previous research may have inadvertently overestimated the role of family structure in reproductive maturation. 相似文献

Valuing practice over theory: How beginning teachers re-orient their practice in the transition from the university to the workplace 总被引:2,自引:0,他引:2
This paper is about the experiences of beginning teachers in turning theory learned in universities into practice in the workplace. The research is situated in the context of a pre-service teacher education programme that explicitly and deliberately seeks to bridge the theory-practice gap in teacher education. The paper argues that, despite long-standing awareness of the theory-practice gap as a central issue faced by beginning teachers, attempts by teacher educators to address this issue remain thwarted. The argument draws on interview and focus group data collected via a study of 1st year graduate teachers of an Australian pre-service teacher education programme. The theoretical perspective of symbolic interactionism is used to focus on the meanings that graduates have of their experiences of turning theory into practice. The data suggest that prospective teachers during pre-service training value both the theory that they learn on campus and the practice that they observe in schools. However, once they become practitioners, they privilege the latter. Upon entry to the workplace, graduates come to associate good practice with that of the veteran teacher, whose practice and cache of resources they seek to emulate. 相似文献
