This article presents results about an investigation on the integration of computer modelling environment to the exploratory learning in Physics. The study is relative to the interaction and performance of university students acting during the use of the semiquantitative computer modelling environment WLinklt in an activity of specific content in Physics: the spring-mass system. The results show that the students presented abilities to develop a model about the proposed system and to relate and make comparison among the results of the model simulation with their previous expectation to modify the model and to explain the behaviour presented by the variables after a simulation. Regarding the dificulties these were related to the delimitation of the system to be studied, the inability of understanding the influence of a variable on the other and what is the causal agent of the system and to the understanding of the function of a connection among two variables and the involved concepts. Therefore, these results are fundamental for the design and development of future researches aiming at promoting, in the practice, the integration of semiquantitative computer modelling environments in the classroom, more specifically for the study of topics of Physics.
