| Abstract (English): |
This document analyzes the work of a group of university students in their attempts to comprehend the concept of derivative. In particular, we focus on analyzing the type of students' cognitive reorganization that they show as a result of using EXCEL as a problem solving tool. The cognitive changes developed by the students are identified through the connections they establish between systems of numeric, graphic and algebraic representations. The work of the students was oriented through the discussion of problems that involve phenomena of the rate of change and linear approximation as fundamental ideas to the understanding the derivative concept.

| Abstract (Spanish): |
Los diferentes medios tecnológicos que se utilizan actualmente en la actividad matemática como calculadoras de álgebra simbólica y software para computadoras, permiten; el manejo simultáneo de diferentes representaciones, la exploración numérica y gráfica de funciones, y la manipulación algebraica etc. El potencial de la tecnología y el papel desempeñado por el profesor en el diseño e implementación de actividades dentro del salón de clase; pueden contribuir a la formación de conexiones entre las ideas matemáticas de los estudiantes.
