Resumen

En este artículo se presentan resultados destacados de un estudio que investigó los efectos del uso de un artefacto computacional en el razonamiento covariacional de los estudiantes y su relación con la transposición informática del concepto de covariación en dicho artefacto. La metodología consistió en un estudio de casos múltiples de la génesis instrumental de profesores de matemáticas en formación en situaciones de covariación con GeoGebra. El uso instrumentado de herramientas para apoyar la cuantificación de la variación articuladas dinámicamente con representaciones de funciones contribuyó a una interpretación covariacional del gráfico y a la coordinación de la covariación continua. Por otro lado, las restricciones estuvieron relacionadas con la representación de la variación con segmentos dinámicos en situaciones de variación negativa y con la influencia de esquemas basados en una visión de función como correspondencia y una visión estática del gráfico.
