QUESTION: What are reusable learning objects and how are they used?

Basically, reusable learning objects (RLOs) are chunks of instruction. They're composed of pieces of information--for instance, facts, concepts, processes, or procedures. Typically, RLOs contain about five to nine of these components, which can be delivered in the form of text, graphics, audio, video, and so forth. Each RLO teaches a discrete piece of knowledge or a component skill and includes practice and assessment.

Once created, reusable learning objects can be used in innumerable online courses. They may also be used for print-based instructional media, PowerPoint presentations, job aids, wall charts, or other training materials. One of the most significant benefits of an RLO strategy is the storage of learning objects in a central database. Once a course component has been electronically linked to an RLO, it is automatically updated as the RLO is revised. That ensures that information is consistently up-to-date.

Being able to reuse learning objects also makes financial sense. Warren Longmire, an instructional designer of e-learning, says that reusing content is good business because its value increases each time it's reused. That's not only because course designers don't have to reinvent the wheel each time they put together a course, but also because they may be able to sell content to others for use in their customized courses.
