Abstract

This paper presents a rationale for designing opportunities for students to reason about the relationship between sources of data and their resulting structures. Students completed a survey about their personal information). Responses were entered into TinkerPlots and attribute names were disguised (i.e., A, B, C, etc.). The students’ task was to examine data from several attributes to analyze their structures and then propose which source (question) from the survey was the best match for a particular attribute. We describe how students reasoned and supported their arguments with a focus on how they used different perspectives in describing data as a pointer, case-value, classifier, and aggregate (Konold et al., 2004). Additionally, we propose a new perspective, data as measurement, used by students to make connections between the data and its source.
