The work presented in this paper discusses the supported forms of the communication tools and the adaptation framework of an asynchronous communication tool in the context of a web-based learning environment, named e-Study (elektroniki spoudi). The purpose of this environment is to support the needs of both instructors and students by means of up to date information regarding developments in the cognitive domain, co-operation, tutorials, “hands on” practice in terms of simulated experiments, access to digital libraries and generally any field related information sources. Moreover, it provides support for distance, collaborative learning and at the same time takes under consideration educational requirements of its users. The learning environment e-Study is based on the e-class platform developed by GUNET and uses reliable open-source components. This system can be used for the development of services that allows the educational collaboration between students and instructors with dynamic content and asynchronous dialogue introduction. For this purpose extra features have been added to the system, in order to assist certain laboratory exercises conduction in a modern and more efficient way. The benefits of such undertaking are multiple. Clearly, communication and interaction between instructors and learners are enhanced, thus raising the quality of the learning process while at the same time ensuring the proliferation of knowledge in general.
