See section 3 for a description of the application of steps two through four of Marsh's (2012, p. 5) data use framework. It is applied specifically to provide data literacy training for pre-service and in-service teachers. The first day of the intervention was primarily focused on scoring the traditional and performance assessments and entering the raw data into Excel datasets. The second day was focused on analysis and interpretation of the traditional and performance assessment data, and making decisions on their basis.
