Modeling is a fundamental activity within the requirements engineering process concerning the construction of abstract descriptions of system requirements that are amenable to interpretation and validation. In this paper we report on a controlled experiment aimed at assessing whether dynamic modeling of system requirements provides an accurate account of stakeholders’ requirements. The context is constituted of second year Bachelor students in Computer Science at the University of Basilicata. The data analysis reveals that there is not significant difference in the comprehension of system requirements achieved by using or not dynamic modeling.
