This paper gives a general presentation of a method for designing, scripting and automatically generating Collectives Educational Activities (CEAs) for distance learning. The CEAs are generated in XML (Extensible Markup Language) and can be integrated in a plate form, as a service. We first present a model which describes the content aggregation. Then, we present briefly the methodology for designing, scripting and generating the CEAs. Finally, we present the tools helping the teachers to design, build and generate the CEAs.
