This article considers CD-ROM instruction in the context of the research path in the library of the interdisciplinary academy. The article also identifies key components of postmodernism (arguing that the library is a site of postmodernism) and barriers to research imposed by library collections and services. How CD-ROMs magnify these barriers to research and offers an instructional method using the active teaching and learning method known as critical pedagogy to empower the researcher. In addition, logistical and content components of the critical pedagogy based CD-ROM workshop are outlined. 相似文献

In the developing world, a common trend is to have north–south collaborations constituting most of the continuous professional development (CPD) activities for librarians. The emerging drift highlighted in this article is a north–south–south initiative aimed at rebuilding the University of Juba Library through capacity-building of the library staff. This article will illuminate the process of equipping library staff with cataloging skills in the absence of previous library training. This endeavor is a result of the collaborative efforts of Makerere University Library (MakLib) in Uganda and the University of Bergen Library (UoBL) in Norway under the Juba Library Automation Project (JULAP). JULAP's main objective is to rebuild the University of Juba Library with the components of library automation and training of library staff. This article will concentrate on the practical training of the library staff in cataloging and the hands-on training on the Koha integrated library system to lay the groundwork for computerized library services for the University of Juba. This article will also highlight the challenges and lessons learned so far while articulating strategies for the future. 相似文献
