Data literacy: what do educators learn and struggle with during a data use intervention?

Data literacy is a prerequisite for making data-based decisions. This paper focuses on the extent to which educators develop components of data literacy during a 1-year data use intervention, as well as what they learn and struggle with concerning these data literacy components. In the data use intervention, teams of teachers, school leaders and a data expert use data to solve an educational problem at their school.

Participants and the data coach indicated that educators had learned, for example, to analyze data with Excel, and to refute misconceptions. Still, there is room for further improvement. For example, educators struggled with formulating a data use purpose that is plausible, sufficiently concrete and measurable
