Resumen
El objetivo de la presente investigación fue comparar las habilidades relacionadas con representaciones gráficas de la información en docentes en formación de la Universidad Nacional de Costa Rica, antes y después de la implementación de un taller de visualización de datos. Se implementó un taller sobre visualización de datos y se elaboraron dos cuestionarios para recolectar la información de la percepción sobre las habilidades del estudiantado en la visualización de datos. La percepción estudiantil fue comparada mediante la prueba tstudent para medidas pareadas y mediante la prueba de rangos de Wilcoxon-Pratt. Los análisis mostraron que las valoraciones estudiantiles sobre sus habilidades de composición gráfica (p < 0,0001), interpretación gráfica (p < 0,0001), representación óptima (p < 0,0001), relación con otras representaciones (p = 0,0004) y relación contextual (p = 0,0003) presentaron aumentos significativos luego de la implementación del taller. Se logró un progreso significativo en todas las áreas evaluadas luego de la implementación del taller, lo cual indica que el estudiantado participante adquirió herramientas fundamentales para comprender, interpretar y utilizar adecuadamente las representaciones gráficas estadísticas en diferentes contextos que involucren gran cantidad de información.
The objective of this investigation was to compare the skills related to graphic representations of information in teachers on training at the National University of Costa Rica, before and after the implementation of a data visualization workshop. A workshop on data visualization was implemented and two questionnaires were developed to collect perception information about the students’ skills in data visualization. Student perception was compared using the t-student test for paired measurements and the Wilcoxon-Pratt rank test. The analysis showed that student ratings of their graphic composition skills (p < 0.0001), graphic interpretation (p < 0.0001), optimal representation (p < 0.0001), relationship with other representations (p = 0.0004) and contextual relationship (p = 0.0003) presented significant increases after the implementation of the workshop. Significant progress was achieved in all areas evaluated after the implementation of the workshop, which indicates that the participating students acquired fundamental tools to understand, interpret and properly use statistical graphic representations in different contexts that involve a large amount of information.
