Abstract

In pharmacology multimedia computer-assisted learning programs (CALs) have proved to be viable educational alternatives to experiments that traditionally use animals. Keeping such programs up-to-date and compatible with an increasing range of delivery platforms is expensive and resource intensive. A new project (RECAL) initiated in 2004 set out to develop a creative solution to this problem.

The key approach was to disaggregate existing CALs into smaller-sized learning objects (LOs) and separate these from the runtime environment enabling teachers to modify programs to suit local curriculum needs, and facilitating reuse and collaboration. This process, which comprises four steps (product research/ analysis; data transcription; LO handling; and authoring/LO re-assembly), has now been further developed, streamlined, automated where possible and documented to assist other educational software developers.

To-date nineteen existing CAL programs have been processed, generating approximately 2000 revitalised and meta-tagged LOs stored in a standards-compliant custom built digital repository. Authorised users can freely download and modify LOs (e.g. translate text into different languages) and upload new LOs for sharing and repurposing within the pharmacology academic community. Handing content control, creation and ownership back to the community should ensure sustainability and expansion of the repository.
