• The Design and Evaluation of Interactivities in a Digital Library

      Budhu, Muniram; Coleman, Anita Sundaram; Wilson, Bonita (CNRI, 2002-11)
      The US National Science Foundation has established a program to create a National Science, Mathematics, Engineering and Technology Education Digital Library (NSDL). One of the subsidiary NSDL libraries under development is the National Civil Engineering Educational Resources Library (NCERL). The first phase of NCERL is the creation and collection of digital resources in three areas of civil engineeringâ geotechnical (soil), rock, and water engineering (GROW). The concept of interactivities guides the design, development, and evaluation efforts of the GROW digital collection. This article describes the salient features of GROW, defines and discusses interactivities as an emerging, integral part of teaching and learning in civil engineering education. Interactivities take place at three distinct levels: the information resource, the collection, and the context. Very simply, the concept of interactivities can be defined as the emphasis on structured representations of interactive multimedia resources. Additionally, resources are designed with rich learning tasks and organized in pedagogical collections supplemented with contextual information. Preliminary evaluation of GROW-NCERL using interactivities is briefly described.
    • Hybrid approaches for measuring use, users, and usage behaviors: A paper submitted to the NSF NSDL Webmetrics Workshop, Costa Mesa, CA, Aug. 2-3, 2004.

      This paper was submitted as part of the requirements and statement of interest for participation in the NSF funded NSDL Webmetrics Workshop in Aug. 2004. It documents GROW's experience with regards to development of webmetrics software and intention to include webmetrics strategies as a part of evaluation. GROWâ s evaluation strategy was articulated in conjunction with the library design and development framework (Budhu & Coleman, 2002). A digital library is a complex thing to evaluate and the â interactivesâ evaluation framework we proposed uses hybrid methods to study distinct layers and objects in the digital library (resource itself, the interface, the search engine, etc.) and understand users and evaluate educational impact. Our Interactives Evaluation strategy has been shared with users and stakeholders at various venues such as the Harvill conference and the NSDL Participant Interaction Digital Workshop, February 2004
