Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months.  相似文献

This article reports on a video project done in an academic library where faculty were included in the production and marketing of the library instruction videos. The videos allowed the librarian to provide a shorter presentation and spend most of her time working individually with each student. The results showed that 97% of the students watched the videos and were able to benefit from the content. The implementation of the videos was a success due to the collaboration of the professors teaching the three courses and the buy-in of the course coordinator; both factors were essential in the success of the video project.  相似文献

The National Institutes of Health (NIH) library instruction program provides training services to staff, clinicians, and researchers across NIH and several Department of Health and Human Services (HHS) operating divisions. The audience, training needs, and training topics are diverse and constantly changing. The NIH library has developed several new services and class topics to meet the needs of its NIH and HHS communities. Context, strategies, and future directions for the NIH library instruction program are described.  相似文献

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed.  相似文献

ABSTRACT

Open education resources represent a great opportunity to reduce textbook costs, but many of them have not been evaluated for quality. Librarians and former students in an introduction to engineering course collected and evaluated open education resources to supplement the course textbook in future semesters. Both searching for and evaluating these resources created opportunities for the librarians to evaluate information literacy skills of these students and to provide instruction to improve these skills.  相似文献

The library literature evaluating the efficacy of online tutorial methods and delivery tools is a valuable resource for librarians looking for information to inform their choices for developing asynchronous online instruction. This literature, however, examines a wide variety of delivery tools, methods, and student populations. As a result, it is difficult to draw definitive conclusions about any one tutorial tool or method. This article compares selected research and concludes that the consensus in the literature suggests that applying adult learning principles to library tutorials has a larger impact on effective online instruction than the individual tool.  相似文献

This case study presents the development and implementation of a personal librarian program for a cohort-based, executive-style higher education administration doctoral program. Librarians and the program director collaborated to create a student-centered program based on individual research needs. The personal librarian program was designed to build a close relationship between the librarian and individual students; to help identify their research knowledge gaps; and to identify resources to meet each individual students' research needs.  相似文献

作为个体的私有资产,知识拥有者不愿意分享知识的同时,常常会表现出推脱型知识隐藏行为。深入探究引发员工推脱型知识隐藏行为的前因和机制,探寻控制这种反生产工作行为的有效措施,将助益企业的知识管理。基于工作要求的视角,分析了工作不安全感对推脱型知识隐藏的差异化影响作用以及任务互依性的适用范围,同时基于JDR理论的“损耗路径”假设,探讨了工作压力的中介作用。通过三时点问卷调查的方式,对收集的308份有效样本数据进行实证分析,结果发现:认知工作不安全感与推脱型知识隐藏之间存在U形的曲线关系;情感工作不安全感正向影响推脱型知识隐藏;任务互依性正向调节情感工作不安全感和推脱型知识隐藏之间的关系;工作压力在情感工作不安全感和推脱型知识隐藏之间存在中介作用。研究结论丰富了工作不安全感的研究视角,阐述了任务互依性不适用的条件和工作要求促发员工反生产工作行为的作用机制,为企业在知识管理中遇到的问题提供了有价值的启示。  相似文献

新中国成立后的17年(1949—1966年)间图书馆学成人教育是新中国图书馆学教育的重要构成部分。文章将这一时期图书馆学成人教育划分为三个阶段,采用历史研究法对各个阶段图书馆学成人教育的相关政策、课程设置、师资队伍、教育管理、教学方法及成就等进行回顾和评论。认为新中国17年图书馆学成人教育发展为新中国培养一大批专业人才,新时期图书馆学成人教育要向继续教育和高层次教育转变。  相似文献
