A standardized procedure was developed for eliciting those details of a library's service policies that are important to its users and for recording the data by checking appropriate categories on a form. This inventory procedure covers the entire spectrum of user services and accommodates a wide range of policies. The inventory was originally designed for use by trained interviewers in largescale surveys of academic medical libraries. However, it is also suitable for other kinds of libraries, and the Interview Guide and Checklist can be used for a self-survey by library staff. In addition to survey use, the inventory has a variety of educational, administrative, managerial, and research applications. A method for weighting the categorical inventory data to reflect the relative desirability of different policies makes it possible to calculate scores indicating how a library's policies compare with those of an "optimal" library. An analogous inventory of the services a library provides to other libraries was developed for surveying major backup resources in the medical library system. 相似文献

This paper describes four different approaches through which an institution can provide a programme for academic staff training and development. The advantages and disadvantages of each approach are analysed with the help of a recently developed theory which seeks to explain why some innovations are successful while others fail. This analysis may contribute towards the development of institutional strategies to ensure the survival—if not the revival—of staff development in universities in the United Kingdom. 相似文献

The importance of research on misconceptions about chemical equilibrium is well recognized by educators, but in the past,
researchers’ interest has centered on student misconceptions and has neglected teacher misconceptions. Focusing on the effects
of adding more reactants or products on chemical equilibrium, this article discusses the various misconceptions held by high
school teachers. A misconception test was administered to two samples of chemistry teachers in Nanjing, China. Of the 109
teachers who participated in the test, only one understood that adding more CS2 gas to the equilibrium system CS2(g) + 4H2(g) ⇌ CH4(g) + 2H2S(g) at constant pressure and temperature can shift the equilibrium to the reactant or product side, depending upon the amount
of CS2 in the initial equilibrium system. Most of the teachers relied on Le Chatelier’s principle and thus made erroneous predictions.
The misconception test also revealed that those teachers who managed to compute equilibrium constants had a limited conceptual
understanding of chemical equilibrium. Implications of these findings for teacher education and chemistry curriculum development
are discussed. 相似文献

As it becomes increasingly difficult to demonstrate the worth of the library to the academic community, gate counts and usage statistics are no longer enough. Showing the impact the library has on the community requires planning new services with outcome measurement from the start. This article outlines a project plan for launching a faculty book delivery service at the University of Central Florida's John C. Hitt Library using Rhea Rubin's (2006) Outcome Measurement model. The article reviews the relevant literature, analyzes the current internal and external climate in which the service will be implemented, discusses the logistical aspects of the service such as cost, delivery method, and staffing, and concludes by determining the goals and outcomes of the service based on these factors. This article is the first in a series of three articles that together make up an entire project planning and management document, including planning, marketing, and assessing the service. The plan in its entirety provides an example of how to apply the Outcome Measurement model in an academic library setting. 相似文献

Problem solving is an important skill in the knowledge economy. Research indicates that the development of problem solving
skills works better in the context of instructional approaches centered on real-world problems. But students need scaffolding
to be successful in such instruction. In this paper I present a conceptual framework for understanding the effects of scaffolding.
First, I discuss the ultimate goal of scaffolding—the transfer of responsibility—and one way that scholars have conceptualized
promoting this outcome (fading). Next, I describe an alternative way to conceptualize transfer of responsibility through the
lens of distributed cognition and discuss how this lens informs how to promote transfer of responsibility. Then I propose
guidelines for the creation of problem solving scaffolds to support transfer of responsibility and discuss them in light of
the literature. 相似文献

An analysis of selected kinematic variables in national and elite male and female 100-m and 200-m breaststroke swimmers 总被引:1,自引:1,他引:1
The kinematic analysis of competition breaststroke swimming has tended to focus on the mean values of swimming speed, stroke rate and stroke length; values in individual lengths, as well as the start, turns and finish, have largely been ignored. This study includes all such variables and aims to improve the coach's holistic understanding of breaststroke racing by determining the relationships and differences between and within these selected kinematic variables. We also compare 100-m events with 200-m events to determine if there are characteristic differences between them. Competitive breaststroke swimming performances in 100-m events (males: n = 159, finishing time = 65.05 +/- 2.62 s; females: n = 158, finishing time = 74.04 +/- 3.66 s) and 200-m events (males: n = 159, finishing time = 141.47 +/- 6.15 s; females: n = 158, finishing time = 158.66 +/- 7.87 s) were collected and analysed from 12 world, international and national championships. The better 100-m and 200-m breaststroke swimmers were found to demonstrate greater competency in the kinematic variables measured, except stroke kinematics, which were unique to each individual. These findings suggest that coaches should place emphasis on all of the kinematic components in training and that they should attempt to identify the stroke rate to stroke length ratio most appropriate for the individual. Finally, characteristic differences do exist between the 100-m and 200-m events, which has implications for how swimmers might train for each event. 相似文献

Twelve Chinese academic journals, indexed by SCI and financed by the National Natural Science Foundation (NNSF), were analysed using the 2000–2003 Total Citations and Impact Factor data from JCR. It is concluded that the quality of Chinese journals is generally low and has remained so despite recent government measures aimed at improvement. Several factors are influential – particularly the Chinese government's policy of encouraging submission to foreign journals. Finance, management, and the academic degree policy are also obstacles. It is suggested that the Chinese government should reconsider its current policies so as to encourage higher quality in domestic periodicals and thus a greater recognition of Chinese journals by the international academic community. 相似文献
