Abstract
Knowledge management, particularly, tacit knowledge management, is a significant guarantee for the development of sustainable educational systems in the e-learning field. The transfer of instructor's tacit knowledge is a key point in promoting the capitalization and exchange of teaching best practices which ensures quality in the learning process. Instructors should be able to share and integrate their teaching know how efficiently within their professional communities of practice. Given the highly interactive nature of Web 2.0 technologies and the benefits of Cloud Computing, managing and sharing of teaching best practices within a knowledge management system for diverse communities represents an interesting opportunity and a real challenge. The aim of this paper is to present a Cloud-based Knowledge Management System that manages gathering and sharing of best teaching practices in e-learning. The proposed system promotes teaching experience exchange and supports the creation and management of communities of practice in a Cloud environment.
