This study explored barriers and facilitating factors affecting the development and use of learning objects in developing instructional materials and their use in supporting individualized learning. Over a two-month period, students in a graduate-level instructional design course developed instructional materials incorporating learning objects or developed learning objects in selected areas or disciplines. Qualitative analysis was conducted to explore students' experience and examine the skills and knowledge required to develop and use learning objects successfully. Through this analysis, three facilitating factors and nine barriers were identified. The authors conclude that the successful development and use of learning objects will be promoted by overcoming the barriers and strengthening the facilitating factors identified in this study.Learning objects are often seen as a way to reuse previously developed instructional materials, not only to enhance learning but also as a means to reduce development costs. Most of the literature to date, however, has focused primarily on various technical aspects related to the storage, retrieval, and reuse of learning objects. For example, much has been written about what a learning object is or is not, about issues of granularity or how large or small a learning object should be, and about metadata and how to tag learning objects to assist in locating appropriate ones for the instructional task at hand.In terms of defining a learning object, many definitions have been proposed.
