Dewhurst D, Cromar S, Ellaway R. RECAL: Creating computer-based alternatives using a sustainable learning objects approach. ALTEX. 2006;23(Special Issue):54-57


Abstract

The mainstay alternatives to using animals in higher education are multimedia computer-assisted learning (CAL) programs simulating pharmacology practical classes. They are intrinsically tied to the authoring application used to create them, are not editable and, with ever changing operating systems, rapidly become obsolete – the only options then being to recreate at further expense or to abandon.

The RECAL project, funded by the Lord Dowding Fund, is developing methods and tools to break this cycle of redundancy and reinvention. The approach is to disaggregate existing CAL programs to separate the learning objects (media elements, sequencing and runtime instructions) from the runtime environment. This allows the learning objects to be changed independently of each other and thereby facilitates reuse and sharing.

Development has so far focused on a Macromedia Flash run-time tool that can read a standards-based XML parameter file, call down the appropriate resources from the repository, in which the resources are catalogued and stored, and provide the interface for the user. Over time, new run-time shells can be built for new platforms or applications.

Rendering the pedagogical design is achieved using IMS Simple Sequencing, which can describe a single learner’s navigation path(s) through a group of learning activities. A RECAL editor will allow teachers to create or adapt both the content and sequencing.

The RECAL project, by adopting principles of standards, objects and reusability, has both improved the long-term viability of CAL alternatives and facilitated their adaptation by teachers to meet local needs and processes.
