Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

  • Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
  • An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
  • Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
  • Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

  • NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
  • NLM should emphasize continuity plans to address project coordinator turnover.
  • NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

This study examines the conditions under which task performance is accomplished more efficiently by a single individual or a group. 116 participants, ranging in age from high school level through holders of Master’s degrees, 58 women and the same number of men, were presented with a computer game based on educational software, arranged in five levels of difficulty. A comparison was made of the speed in which objectives were attained when performed individually and when divided among groups of two to four partners, controlling for the type of coordination required. Cases of expedient and inexpedient division of labor were identified, as were factors affecting feasibility, among them the number of simultaneous tasks to be performed, complexity level, number of participants and the intensity of coordination required among them. Basic principles, pertaining to the functional division of roles in learning activities and in educational administration, are discussed.  相似文献

This study examines the hypothesis that the more support beginning mathematics teachers perceive and the better they evaluate the management of their school, the higher their teaching quality is. Indicators of teaching quality were how the teachers, who were in their third year in the profession, regarded themselves able to cope with the challenges of mathematics instruction and generic tasks like classroom management and how satisfied they were with their job. Indicators of support were the level of appraisal and autonomy the teachers reported. School management indicators were the administrative leadership of the principal and the climate of trust as perceived by the teachers. Our results reveal that teacher support plays an important role in the quality of beginning mathematics teachers. All quality indicators improved significantly if beginning teachers reported more appraisal and autonomy. A climate of trust plays an important role for the extent of autonomy perceived. Administrative leadership was significantly related to the amount of appraisal the teachers reported. Our results provide important information on how to steer a school so that the quality of beginning mathematics teachers is maximized.  相似文献

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010 Baker, R. S. J. d., Goldstein, A. B. and Heffernan, N. T. 2010. “Detecting the moment of learning”. In Proceedings of the 10th Annual Conference on Intelligent Tutoring Systems 2534. In V. Aleven, J. Kay, & J. Mostow (Eds.),pp.Heidelberg, Germany: Springer.[Crossref] [Google Scholar], 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time.  相似文献

Community colleges have become increasingly reliant on diversifying their revenue sources, and turning to private fund raising has become a common strategy for many of them. Although fund raising has been a common practice in higher education since its inception, it has only emerged in the two-year college sector in the past several decades. The current study sought to identify donors at a case study, suburban community college, specifically exploring giving patterns over time and testing the conceptual framework of a pyramid of giving that overlays institutional involvement and commitment with giving levels. Major infrastructure inconsistencies prevented much of the framework testing, but data were capable of creating an initial donor and giving profile for a typical community college. This profile demonstrated that board members and employees were the most loyal and consistent in making contributions, but that these gifts often were stable over time and did not increase to become major gifts. Also, private business and industry gifts were often given at the same level as individual gifts, perhaps illustrating the responsiveness and cooperation between community colleges and the local workforce.  相似文献

This essay explores the relations between T. S. Eliot's concept of tradition and the ‘modern materialism’ of Walter Benjamin, Jacques Lacan and Louis Althusser, and considers the implications of this resonance for both Eliot's critical legacy and the Marxist tradition. Initially surveying the critical controversy surrounding the canonical figure of Eliot and recent attempts to reconcile his avant-garde poetics with his reactionary social thought, the essay traces the roots of Eliot's tradition in a Nietzschean critique of historicism and its development into a theory of culture. Eliot's persistent drive towards impersonality echoes (and problematises) the efforts of Benjamin, Lacan and Althusser to construct a model of the social process that incorporates the unconscious. Rather than ultimately determining a set of political positions, the ‘missed encounter’ between Eliot's tradition and ‘modern materialism’ draws to light the Hegelian historicisms that haunt materialist theories of culture.  相似文献

This exploratory study examined the influence of national and organizational culture on the use of various performance improvement interventions. Data on intervention use were collected from practitioners in the United States and South Asia. Results revealed that orientation programs, organizational communication, instructor‐led training, and performance appraisals were among the most used interventions in both the United States and South Asia. Findings also indicated that factors such as organization size, location of headquarters, learning and development budget, and reporting structure are related to the use of interventions. Practitioners in South Asia predominantly had expertise in disciplines such as human resources, while those in the United States had experience in instructional design and human performance technology. These differences may influence the development and implementation of instructional and noninstructional interventions.  相似文献

Few data exist on gender-typed and gender-segregated play in hunter-gatherer societies, despite their unique demographic and cultural features which may influence children’s gendered play. Using naturalistic observations of Hadza (N = 46, 41% female) and BaYaka (N = 65, 48% female) hunter-gatherer 3- to 18-year-olds from Tanzania and the Republic of Congo, we showed that access to playmates was negatively associated with playing in mixed-gender groups. Young boys did not engage in more rough-and-tumble play than girls, but adolescent boys participated in this type of play more than adolescent girls. Children were also more likely to participate in work-themed play which conformed to gender norms within their society. Findings are discussed within the context of gendered division of labor, child autonomy, and demography.  相似文献
