ab: Summary: This paper focuses on children creating representations on paper
for situations that change over time. We articulate the distinction
between homogeneous and heterogeneous spaces and reflect on
children’s tendency to create hybrids between them. Through classroom
and interview examples we discuss two families of tasks that seem to
facilitate children’s development of homogeneous spaces: (1) making
selected features directly visible, instead of requiring intermediate
steps and calculations; for example, to be able to directly compare
different sets of data combined in a single graph, and (2) exploring
well-defined figural components that can be used in graphing, such as
line segments or sequencing from left to right, that are introduced as
a resource.
