We present the design of an online environment providing mechanisms for the exploitation of school ICT infrastructure by empowering teachers to discover and comment on educational activities (patterns, scenarios, experience reports) that can be implemented in their schools. To this end, our design approach will make explicit the linking between the patterns, the learning scenarios and other contextual information. The online environment will not only serve as a repository of educational activities but will help schools to analyze their infrastructure, to select proper scenarios that effectively exploit it and, potentially, to enrich these scenarios by commenting on them.
