• Resumen

  • Several representational forms are now used to communicate important mathematical ideas. These different representations fundamentally affect how people interpret and use those ideas. However, graphical representations of data are no longer the typical static representations taught in secondary classrooms. Technological advances have given rise to nontraditional, multi-dimensional graphical representations that could not be displayed on a two-dimensional sheet of paper. Here, Angotti explores a dynamic time-series graph, one of such representation that can be found at http://www.gapminder.org. Gapminder was created by a team of developers to create beautiful, interactive graphs of otherwise lifeless numbers. Their goal is increased use and understanding of statistics and data that specifically focus on social, economic, and environmental development both locally and globally. Gapminder is free and can be run online or downloaded and installed as a stand-alone from computers that do not have network access.
