Supporting peer assessment in learning management systems is an important educational issue. The widespread Moodle platform relies on a plugin called Workshop for providing such peer evaluation functionality. In a previous work, we proposed an extension of the plugin with student modeling capabilities, based on a Bayesian Network approach. In the current paper we aim to experimentally validate this Enhanced Workshop module, by using it in the context of an Introduction to Computer Programming course. An experience report of the peer assessment process is provided, focusing on the support offered by the module. The results are also analyzed, exploring the relationship between student models and grades.
