Quantifying the reuse of learning objects

Abstract

This paper reports the findings of one case study from a larger project, which aims to quantify the claimed efficiencies of reusing learning objects to develop e-learning resources. The case study describes how an online inquiry project Diabetes: A waste of energy was developed by searching for, evaluating modifying and then integrating as many pre-existing learning objects as possible into a learning design. Development times for the reuse approach were recorded and compared to estimates for the de novo development of an equivalent project. Outcomes suggest that considerable savings can be made using the reuse approach; we estimate a threefold increase in time to develop the Diabetes projec..
