The Greek Ministry of Education has initiated the project "Digital School" since September 2011. One of the actions of the Digital School concerns the development of digital interactive books (in html) for all school courses. These interactive books are enriched with digital components with activities which are embedded in them. The Course Management System "eClass" was selected as the platform to support the project and to provide the place for communication and collaboration among the teachers participating in the project. It is supported that teaching with such interactive books offers some advantages such as offering to the students more opportunities for engaging and interacting with the books content, multiple representations of the content information, which are expected to result to the better imprint in the students' memory. We envisage that this kind of interaction with the content of the books of Religion will create favorable conditions for the teaching approach of the course of Religion and it will be an initiative for renewal of its teaching strategies.
