Evaluating learning resources for reusability: the "dner & learning objects" study

The DNER&LO study gathered data about 27 elearning projects, mapping the categories of content being produced, and approaches to reusability and interoperability. Eighteen were chosen for closer study and evaluation, based on availability of content, and on covering a wide range of content categories. Appropriate reusability evaluation criteria were developed specifically for the study, in four areas: aggregation level; reusability; subject specificity; and vertical reusability. Developing the criteria definitions in the light of real, varied content illuminated the present lack of a widely used, authoritative elearning terminology. Although the projects were planned before reusability was a widely promoted goal, they showed high levels of awareness of, and willingness to plan for, reusability and interoperability. The content itself, evaluated according to the criteria, showed good potential for reuse, or for being made reusable. Any gaps between the awareness levels of developers and actual reusability of content supported the idea that planning, and budgeting from the start for the complex process of developing reusable resources is imperative, if the potential of learning technology for sharing resources is to be fulfilled. Gaining support from sources such as the UK’s CETIS is one way to ensure available expertise is utilised.
