Usability Evaluation of Learning Object Indexation: The ARIADNE Experience
نویسندگان
چکیده
This paper investigates usability problems of indexation tools for Learning Objects. Such tools are used to describe and deploy learning objects with their metadata in Learning Object Repositories (LOR’s). Metadata is provided to facilitate the search and management of learning objects. The complexity of manually indexing learning objects results in a bottleneck for the introduction of such objects (Duval and Hodgins, 2003), (Kabel, et al., 2003). In this paper, we present the results of a usability evaluation aimed at determining some usability issues in two ARIADNE indexation tools. Results show that metadata semantics is significantly influenced by usability perspectives (such as the user interface, functionalities provided, domain knowledge, etc). The findings and recommendations of this study are generalised for other indexation tools.

Web services for the ARIADNE Knowledge Pool System
This paper presents an architecture based on web services for learning object repositories (LOR). This architecture enables to facilitate the indexation process by integration of a LOR into applications where learning objects are either produced or consumed. Also, it is designed to provide interoperability with other LORs.

The challenge of finding appropriate learning objects is one of the bottlenecks for end users in Learning Object Repositories (LORs). This paper investigates usability problems of search tools for learning objects. We present findings and recommendations of an iterative usability study conducted to examine the usability of a search tool used to find learning objects in ARIADNE Knowledge Pool Sy...
متن کاملThe effects of discipline on the application of learning object metadata in UK higher education: the case of the Jorum repository
Metadata can support multiple roles in the provision of e-learning, including the description, management, retrieval and re-usability of learning objects and learning designs, as well as the delivery of on-demand and personalised learning experiences to users. For this purpose, a variety of educational or learning object metadata standards and schemas have been developed, including the Dublin C...
متن کاملTowards Interoperable Learning Object Repositories: The Ariadne Experience
In this paper, we present an approach for producing interoperable metadata by mapping metadata structures of application profiles into standard metadata structures. As a study case, we map the ARIADNE metadata structure into the LOM structure. We use XSLT to transform ARIADNE XML instances into IEEE LOM Instances. Finally, we validate the resulting LOM XML instances. The major contribution of t...
متن کاملLearning object repositories are useful, but are they usable?
Learning Object Repositories seems to be the solution to facilitate the sharing and reusing of learning material. As useful as they may appear, Learning Object Repositories are not in widespread use among faculty around the world. There are indications that the amount of work and time required to use the Repositories is the main reason for the reluctance of teachers. This work analyzes the tool...
