摘要：We give the results of a pilot study carried out at UNEXPO (Venezuela) with Calculus I students, the aim of which was to determine the concept of area and definite integral held by those students after they had undergone instruction using as curricular material a set of Laboratory Practices (LP) designed with DERIVE CAS (Computer Algebra System). At the end of the instruction period, the students were given a questionnaire adapted from those used by Orton (1983), Mundy (1984) and Calvo (1997) in their research work. Taking into account, among other things, the answers given by the students, we chose two of them who were then interviewed. Analysing the results obtained, we can conclude that the instruction programme used allows students to progress slightly in their use of graphic and numerical aspects of the concept of definite integral
