Creating Reusable Educational Components: Lessons from DLESE

Reuse of educational materials is integral to many educator tasks, from designing a course to preparing for a lab or class. This article describes a study on the reuse of educational materials in the context of the Digital Library for Earth System Education (DLESE), a community-owned and governed facility offering high-quality teaching and learning resources for Earth system education. The study noted that educational resource designers often do not develop components with reuse in mind, making it more difficult or impossible for other educators to find and use their material, and that the 'findability' and reusability of community-created digital educational resources is highly dependent on the presentational and structural design of the resources themselves. The authors recommend that all resources clearly state the creator's name and contact information, relevant copyright restrictions, the most significant date for the resource (specifying creation or revision), and the intended grade level.

What is usability in the context of the digital library and how can it be measured?

This paper reviews how usability has been defined in the context of the digital library, what methods have been applied and their applicability, and proposes an evaluation model and a suite of instruments for evaluating usability for academic digital libraries. The model examines effectiveness, efficiency, satisfaction, and learnability. It is found that there exists an interlocking relationship among effectiveness, efficiency, and satisfaction. It also examines how learnability interacts with these three attributes

This is what I'm doing and why: reflections on a think-aloud study of digital library users' information behaviour

Many user-centred studies of digital libraries include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using digital libraries to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the system(s) used or understanding aspects of users‟ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on their methodologies. In this paper, we discuss and reflect on the decisions made when planning and conducting a think-aloud study of lawyers‟ interactive information behaviour. Our discussion is framed by Blandford et al.‟s PRET A Rapporter („ready to report‟) framework – a framework that can be used to plan, conduct and describe user-centred studies of digital library use from an information work perspective

Moving data into and out of an institutional repository: Off the map and into the territory

Given the recent proliferation of institutional repositories, a key strategic question is how multiple institutions - repositories, archives, universities and others—can best work together to manage and preserve research data. In 2007, Green and Gutmann proposed how partnerships among social science researchers, institutional repositories and domain repositories should best work. This paper uses the Timescapes Archive—a new collection of qualitative longitudinal data— to examine the challenges of working across institutions in order to move data into and out of institutional repositories. The Timescapes Archive both tests and extends their framework by focusing on the specific case of qualitative longitudinal research and by highlighting researchers' roles across all phases of data preservation and sharing. Topics of metadata, ethical data sharing, and preservation are discussed in detail. What emerged from the work to date is the extremely complex nature of the coordination required among the agents; getting the timing right is both critical and difficult. Coordination among three agents is likely to be challenging under any circumstances and becomes more so when the trajectories of different life cycles, for research projects and for data sharing, are considered. Timescapes exposed some structural tensions that, although they can not be removed or eliminated, can be effectively managed

Report of the Stanford Linked Data Workshop

The Stanford University Libraries and Academic Information Resources (SULAIR) with the Council on Library and Information Resources (CLIR) conducted at week-long workshop on the prospects for a large scale, multi-national, multi-institutional prototype of a Linked Data environment for discovery of and navigation among the rapidly, chaotically expanding array of academic information resources. As preparation for the workshop, CLIR sponsored a survey by Jerry Persons, Chief Information Architect emeritus of SULAIR that was published originally for workshop participants as background to the workshop and is now publicly available. The original intention of the workshop was to devise a plan for such a prototype. However, such was the diversity of knowledge, experience, and views of the potential of Linked Data approaches that the workshop participants turned to two more fundamental goals: building common understanding and enthusiasm on the one hand and identifying opportunities and challenges to be confronted in the preparation of the intended prototype and its operation on the other. In pursuit of those objectives, the workshop participants produced:1. a value statement addressing the question of why a Linked Data approach is worth prototyping;2. a manifesto for Linked Libraries (and Museums and Archives and …);3. an outline of the phases in a life cycle of Linked Data approaches;4. a prioritized list of known issues in generating, harvesting & using Linked Data;5. a workflow with notes for converting library bibliographic records and other academic metadata to URIs;6. examples of potential “killer apps” using Linked Data: and7. a list of next steps and potential projects.This report includes a summary of the workshop agenda, a chart showing the use of Linked Data in cultural heritage venues, and short biographies and statements from each of the participants

Usability evaluation of digital libraries: a tutorial

This one-day tutorial is an introduction to usability evaluation for Digital Libraries. In particular, we will introduce Claims Analysis. This approach focuses on the designers’ motivations and reasons for making particular design decisions and examines the effect on the user’s interaction with the system. The general approach, as presented by Carroll and Rosson(1992), has been tailored specifically to the design of digital libraries. Digital libraries are notoriously difficult to design well in terms of their eventual usability. In this tutorial, we will present an overview of usability issues and techniques for digital libraries, and a more detailed account of claims analysis, including two supporting techniques – simple cognitive analysis based on Norman’s ‘action cycle’ and Scenarios and personas. Through a graduated series of worked examples, participants will get hands-on experience of applying this approach to developing more usable digital libraries. This tutorial assumes no prior knowledge of usability evaluation, and is aimed at all those involved in the development and deployment of digital libraries
