UTL-CL: A Declarative Calculation Language Proposal for a Learning Tracks Analysis Process

In this paper, we propose a track analysis process about the activity in learning systems that helps teachers to benefit of the experience and the knowledge of the community in the usage analysis.We also propose a language for calculation of teachers' observation needs. This language will be implemented in tracks' analysis tools, which support teachers to establish their tracking needs in order to improve the pedagogical scenario that they designed.
