Transnumeration and Data Visualization: A Look at Graphic Analyses of Data Mediated by Gapminder

This article reports on part of a study to explore the possibilities of graphical data analysis mediated by using technological resources. The research considers transnumeration and data visualization to present analyses about the use of Gapminder in a statistics class for teachers in initial training. The qualitative methodology and data analyses result from participatory observation and access to class activities performed by the future teachers. The results elucidate that the use of Gapminder allowed participants to select representations, including dynamic representations, of statistical data and to interact with graphic representations, resulting in the technology serving as a resource that facilitated their interpretations and understandings about real problems.
