The content of sex education in government-funded schools in the USA varies dramatically and reflects its contested nature and goals. Drawing from 50 interviews with sex educators working in the public, government-funded school system in a Midwestern US state, this study explores the processes through which sex educators decide what and how to teach. Working from the theoretical framework of argument sphere theory, and, specifically, socio-scientific controversy, we find that sex educators often resolve the competing arguments they face through processes that we call deliberative conflation and deliberative co-optation. Deliberative conflation involves the use of criteria from one or more argumentative spheres to judge evidence appropriate to a different sphere. Deliberative co-optation involves the use of discourse practices from one sphere to make arguments actually grounded in another. Both of these processes enable the reconciliation of otherwise incommensurate arguments, but they do so in ways that foster unstable and ambiguous curricular decisions. Our findings provide guidance towards improving sex education and its attendant outcomes. 相似文献

This article explores how an experienced teacher navigates the demands of curriculum to implement her inquiry-centered teaching and learning philosophy, and how administrators along the way supported her during this change. Interviews with this classroom teacher surface suggestions for twenty-first-century professional development and support, including the development of equitable, intellectual, and trusting relationships between teachers and administrators, attitudes of curiosity and availability on the part of administrators, and the use of documentation to provide evidence and visibility of meaningful teaching and learning. This article invites teachers interested in change and administrators committed to supporting competent teachers to consider the strategies proposed. 相似文献

Genetic sequence and hyper-methylation profile information from the promoter regions of tumor suppressor genes are important for cancer disease investigation. Since hyper-methylated DNA (hm-DNA) is typically present in ultra-low concentrations in biological samples, such as stool, urine, and saliva, sample enrichment and amplification is typically required before detection. We present a rapid microfluidic solid phase extraction (μSPE) system for the capture and elution of low concentrations of hm-DNA (≤1 ng ml−1), based on a protein-DNA capture surface, into small volumes using a passive microfluidic lab-on-a-chip platform. All assay steps have been qualitatively characterized using a real-time surface plasmon resonance (SPR) biosensor, and quantitatively characterized using fluorescence spectroscopy. The hm-DNA capture/elution process requires less than 5 min with an efficiency of 71% using a 25 μl elution volume and 92% efficiency using a 100 μl elution volume. 相似文献

Up until now, CEPES, the UNESCO European Centre for Higher Education, was more concerned about universities than about the academies of sciences in the countries making up the region it serves, even though both types of institutions do research. Although university teaching was traditionally linked to research as in the Humboldtian model of the university, the two functions became increasingly separate in eastern Europe. Now, as eastern and central Europe undergo transition to democracy and market economies, it is perhaps time to consider a redefinition and possibly a fusion of roles with academies and universities co‐operating closely for excellence in teaching and in research. 相似文献

Lifelong learning puts learner self-direction centre-stage. However, increased responsibility should not come at the price of over-burdening or abandonment of learners as they progress along their learning journey. This paper introduces an approach to wayfinding support for lifelong learners based on self-organisation theory. It describes an architecture which supports the recording, processing and presentation of collective learner behaviour designed to create a feedback loop informing learners of successful paths towards the attainment of learning goals. The approach is presented as an alternative to methods of achieving adaptation in hypermedia-based learning environments which involve learner modelling. The article concludes with a discussion of the questions being addressed in our ongoing research. 相似文献

This study focuses on the factors that determine study progress and numerical success rate in higher education. Study progress is influenced at three levels, namely the student level, course/institute level and government level. It is expected that various groups of economic, social, psychological and organisational factors will together influence the study progress. This study uses a multi-level and multi-disciplinary framework, in so far as it considers all of these factors at the different levels. The database contains about 9,000 students and 60 courses at the institutional level. The results show the relative importance of student level and institutional factors on study progress. 相似文献

This study presents a model of lifestyles based on the form of women's acculturation to academic life. The model rests on the assumptions of patterned behavior and values which can be termed women's culture and academic culture respectively. Since becoming academics requires women to mediate the boundary between behaviors expected of women and those expected by the overwhelmingly male academic profession, an acculturation rather than socialization model was employed.The in-depth study of the acculturative modes of professional behavior is both an exploratory and a qualitative effort to derive issues and categories from women's own perceptions. Forty-two women from diverse disciplines and institutions were interviewed. Interviewees were either advanced PhD candidates or had recently entered professional work.Three modal categories emerged from content analysis of intensive interviews. Reorientation reflected the effort of women to exemplify the norms of male academic culture. Reaffirmation required the command of both professional norms and traditional feminine roles and values. Reconstitution was an effort to reformulate professional participation into a lifestyle more compatible with women's cultural norms. 相似文献

Women at obstetric high risk more often experience negative feelings related to childbirth than women with normal outcomes. For these high-risk women, an individual birth plan does not appear to improve the overall experience of childbirth; rather, it seems to intensify the negative feelings in several aspects. The increased vulnerability in women at high risk warrants special attention to the possibility that types of care routinely offered to all women may negatively influence the experiences of high-risk women. 相似文献

Changes in respiration amplitude, respiration rate, and heart rate in response to a conditioned signal for shock were measured concurrently in kittens and adult cats. The data were analyzed with respect to qualitative and quantitative variability across trials and subjects; correlation among measures; skewness; and kurtosis. Suppression of respiration amplitude was the most reliable response across trials and subjects, with increases in respiration rate second and heart rate by far the least reliable. Correlations between each pair of measures were moderate. Respiration-amplitude responses were negatively skewed, but this deviation from normality was moderate and consistent across subjects. The measurement of conditioned respiratory suppression is a viable addition or alternative to the conditioned emotional response procedure in studies of classically conditioned fear. 相似文献
