dc.description	To study the roles that the graphing calculator plays in solving problems about functions, a small quasi-experimental study was conducted with four pairs of undergraduate students solving problems with and without the graphing calculator. The analysis of the protocols of the sessions did not reveal major differences that could be attributed to the presence or absence of the tool but indicated differences in strategies used with each problem that could be explained in terms of the nature of the knowledge at stake and to students’ availability of that knowledge. The study suggests a model for conducting research that looks for explaining the effects of technology in learning and instruction. </p> <p>Con el fin de analizar el papel que la calculadora gráfica juega en la resolución de problemas sobre funciones, se hizo un pequeño estudio cuasi-experimental con cuatro pares de estudiantes de pre-grado variando la condición de la disponibilidad de la calculadora. El análisis de los protocolos de las sesiones revela que no hay mayores diferencias que se puedan atribuir a la presencia o ausencia de la calculadora gráfica; sin embargo, las diferencias observadas en el uso de estrategias que se usaron en cada problema pueden explicarse en términos de la naturaleza del conocimiento en juego y de la disponibilidad de tal conocimiento para los estudiantes. El estudio sugiere además un modelo para realizar investigaciones que busquen explicar los efectos de la tecnología en el aprendizaje y en la instrucción.
