E-learning materials development is typically acknowledged as an expensive, complicated, and lengthy process, often producing materials that are of low quality and difficult to adapt and maintain. It has always been a challenge to identify proper e-learning materials that can be reused at a reasonable cost and effort. In this paper, software engineering reuse principles are applied to e-learning materials development process. These principles are then applied and implemented in a prototype that is integrated with an open-source course management systems. The reuse of existing e-learning materials is beneficial in improving developers of elearning materials productivity. E-learning material reuse is performed, in this research, based on construct's granularity rather than on unified constructs of one size.
