Patterns for Collaborative Learning in E-learning: Analysis Level Directed by Cases of Use and Sequence Diagrams

This paper aims to present patterns for collaborative learning directed by cases of uses and sequence diagrams for re- use of learning objects. A proposal is based taking the theory from the UML model and proposing an extension to model a collaborative learning with: cases of use (CLUC)and sequence diagrams for collaborative learning (CLSD). This paper is based on the MACOBA model which proposes by the construction levels of collaborative learning objects(CLO). The work is centered in the analysis level in one second part which responds to model what must make the object of learning. In this way the elements will appear to model the collaborative learning in promotion of re-use in the analysis phase.
