Learning object metadata surrogates in search result interfaces: user evaluation, design and content
The purpose of this research was to evaluate user interaction with learning object
metadata surrogates both in terms of content and presentation. The main objectives of
this study were: (1) to review the literature on learning object metadata and user-centred
evaluation of metadata surrogates in the context of cognitive information
retrieval (including user-centred relevance and usability research); (2) to develop a framework for the evaluation of user interaction with learning
object metadata surrogates in search result interfaces; (3) to investigate the usability of metadata surrogates in search result interfaces
of learning object repositories (LORs) in terms of various presentation aspects
(such as amount of information, structure and highlighting of query terms) as a
means for facilitating the user relevance judgment process; (4) to investigate in-depth the type of content that should be included in learning
object metadata surrogates in order to facilitate the process of relevance
judgment; (5) to provide a set of recommendations—guidelines for the design of learning
object metadata surrogates in search result interfaces both in terms of content
and presentation. [Continues.
