The integration of existing educational computer-based tools is a current research trend aimed at increasing the range of learning situations that can be supported by most widely adopted Virtual Learning Environments (VLEs). Nevertheless, due to the technological and functional heterogeneity of both tools and VLEs, there is an integration cost that must be assumed and that varies depending on several design issues. This paper identifies the issues to be tackled when designing a VLE or a tool and the effects that the different alternatives may have in the integration cost. Besides, the paper discusses the advantages and drawbacks of previous research proposals when dealing with such issues. The final goal is to understand the impact of design decisions in the chances for acceptance of the adopted integration approaches.
