Competency theory predicts a miscalibration between students' self-assessments of their information literacy skills and their actual skill level. This study investigates whether such a disparity is evident among incoming freshmen who test as non-proficient on a standardized test of information literacy. In addition, this study analyzes Information Literacy Test scores and library anxiety test scores to provide preliminary data on whether library anxiety is related to information literacy skill attainment. Findings reveal that the relationship between information literacy skills and self-assessments predicted by competency theory are evident in the domain of information literacy. This study did not find an association between information literacy skill scores and total library anxiety scores. However, a significant negative correlation between information literacy scores and the subscale “knowledge of the library” indicates that as information literacy scores rise, anxiety scores related to a lack of knowledge of the library fall. The findings suggest that traditional information literacy instruction may not be effective with non-proficient students, who are unlikely to see themselves as needing or benefiting from such instruction.  相似文献

Major troubling contours of neoliberalism and high-stakes education have common features. Consequently, the author discusses how multicultural education can serve as praxis for collective empowerment in a globalized context. The author asserts that equitable representation and localized multicultural knowledge production are the foundation of a transformative democracy and engaged citizenry.  相似文献

This paper examines the role of ethics in research with potentialapplicability to chemical and biological warfare. It focuses uponbiological warfare research, and examines the ethical dilemmas faced bythose working with dual-use potential technologies. It discusses thenormative, legal and ethical prohibitions against participation inchemical and biological warfare programmes from a Western perspective.It examines the motivations of individuals participating in CBW researchand concludes with recommendations for increasing awareness aboutethical and normative prohibitions. An appendix lists the results of asurvey of ethical codes in relevant scientific disciplines conducted viathe Internet.  相似文献

Mexican immigrant farm-worker mothers’ class, race, citizenship status, and jurisdictional status of their town in a Northern California community rendered them invisible. However, when the school board decided to close the elementary school the mothers mobilized. Drawing on these mothers’ fototestimonios we examine how they, as cultural citizens, resisted local practices of educational inequity. They wanted to ensure an education for their children. The fototestimonios reveal how farm-worker mothers: (1) negotiated as a collective with the school board; (2) sought negotiation and schooling alternatives; and (3) expressed cultural citizenship through collective efforts to be included within the US polity.  相似文献

Scripted lesson plans and/or professional development alone may not be sufficient to encourage teachers to reflect on the quality of their teaching and improve their teaching. One learning tool that teachers may use to improve their teaching is Lesson Study (LS). LS is a collaborative process involving educators, based on concepts of iteration and revision, to improve instruction. The initial use of an adapted version of LS referred to as a microteaching lesson study (MLS) is described in this article. Our purpose is to illustrate the process of MLS used by a group of researchers when developing lesson plans for teaching students with learning disabilities. We describe MLS, and then (1) share an application of MLS used by a research team in developing a writing intervention, and (2) discuss how the MLS format was mirrored with K‐12 teachers during professional development training.  相似文献

Circulating tumor cells (CTCs) are important biomarkers for monitoring tumor dynamics and efficacy of cancer therapy. Several technologies have been demonstrated to isolate CTCs with high efficiency but achieve a low purity from a large background of blood cells. We have previously shown the ability to enrich CTCs with high purity from large volumes of blood through selective capture in microvortices using the Vortex Chip. The device consists of a narrow channel followed by a series of expansion regions called reservoirs. Fast flow in the narrow entry channel gives rise to inertial forces, which direct larger cells into trapping vortices in the reservoirs where they remain circulating in orbits. By studying the entry and stability of particles following entry into reservoirs, we discover that channel cross sectional area plays an important role in controlling the size of trapped particles, not just the orbital trajectories. Using these design modifications, we demonstrate a new device that is able to capture a wider size range of CTCs from clinical samples, uncovering further heterogeneity. This simple biophysical method opens doors for a range of downstream interventions, including genetic analysis, cell culture, and ultimately personalized cancer therapy.  相似文献
