ABSTRACT

This article uses the case study of developing a collaborative “out-of-hours” virtual enquiry service by members of the Northern Collaboration Group of academic libraries in the north of England to explore the importance of communication and collaboration between academic library services in enhancing student learning. Set within the context of a rapidly changing UK higher education sector the article considers the benefits and challenges of collaboration and the contribution of library services to the student experience. The project demonstrated clear benefits to student learning and evidence of value for money to individual institutions as well as showing commitment to national shared services agendas. Effective communication with students, with colleagues and stakeholders in our own and other Northern Collaboration member institutions, and with OCLC, our partner organization, was a critical success factor in the development, promotion, and uptake of the new service.  相似文献

Abstract

A problem sequence is presented developing the basic properties of the set of natural numbers (including associativity and commutativity of addition and multiplication, among others) from the Peano axioms, with the last portion using von Neumann’s construction to provide a model satisfying these axioms. This sequence is appropriate for mathematically inclined students in their first or second years, and has regularly required about a week of class time. The sequence could be included as one unit within any of several appropriate courses, and could be an ideal “trial size” first attempt at guiding inquiry-based learning in the tradition of R.L. Moore.  相似文献

SMAR2T: Science and Mathematics Academy for the Recruitment and Retention of Teachers is an NSF-funded project for the alternative certification of science and mathematics teachers. Since 2003, we have recruited 4 cohorts of students for 2 different routes to postbaccalaureate teacher certification for teaching grades 5–12. Because we did not meet our target numbers for the recruitment of the 1st cohort, we examined our recruitment strategies and their effects. In this paper, we discuss strategies used to recruit for the 1st SMAR2T cohort and the outcomes of those strategies. We present ongoing recruitment efforts and data on inquiries and applicants for the 2nd cohort. Finally, we highlight the intentional and unintentional gatekeepers of our program and present implications for others engaged in designing and implementing alternative pathways certification.  相似文献

This article describes and analyzes the design dynamics of a school principal self-assessment process, provided through a three-day, state-approved Leadership Assessment Academy, which allows principals to experience and reflect on important self-assessment data that leads to a personal professional growth plan. Designing and implementing such an academy is complex and requires careful consideration of all aspects of the principalship and the requirements set forth by the state regarding principal assessment and professional growth plans. A primary challenge of this leadership academy is in providing principals with a self-assessment experience that is meaningful and accurate using carefully designed assessment techniques and technology, and that can serve as a viable alternative to the traditional paper and pencil assessment tools that require very little personal involvement in defining and producing the principal's professional growth plan.  相似文献

Previous evidence suggests that a disruptive stimulus presented during the delay interval of a delayed matching-to-sample trial increases the rate of forgetting by pigeons. However, disruptive events have generally been presented for a period of time proportional to the delay interval. Thus, the observed increase in forgetting may be the result of greater exposure to these events at longer delays than at shorter ones. This possibility was examined by comparing the effects of houselight illumination for the entire delay, half the delay, or a constant 1.5 sec of each delay on pigeons’ delayed matching-to-sample accuracy. Presenting the houselight for a period of time proportional to each delay (i.e., the entire delay or half the delay) impaired accuracy more at longer delays than at shorter delays. By contrast, when the houselight was illuminated for 1.5 sec, irrespective of delay length, there was a greater impairment in accuracy at shorter delays than at longer delays. Thus, the increased rate of forgetting previously reported in the literature may be the result of unequal application of a disrupting stimulus across delays.  相似文献
