abstract = {Summary: The aim of this study is to analyse the different representations, resources and solutions shown by first-year engineering students working on a set of problems involving the concept of the definite integral using Derive software. Three student profiles emerge from an analysis of their problem-solving approaches: students who used the software as a means of validating and verifying their pen-and-paper work, students who used the tool to graphically represent the functions using them to calculate the approximated areas, and students who combined both pen-and-paper and tool approaches to solve problems, but often made mistakes when connecting the concepts that arose in studying the definite integral with some of the previously studied basic ideas (and procedures). It can be concluded that, in some cases, the use of Derive software helped students to identify and use ideas that are needed for a fuller understanding of their initial approaches to solving problems.},
