• Resumen

  • 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.
