The Effect of a Data-Based Instructional Program on Teacher Practices

Abstract

Data-based instructional programs, including interim assessments, are a common tool for improving teaching and learning. However, few studies have rigorously examined whether they achieve those ends and contributors to their effectiveness. This study conducts a secondary analysis of data from a matched-pair school-randomized evaluation of the Achievement Network (ANet). Year-two teacher surveys (n=616) and interviews from a subset of ANet school leaders and teachers (n=40) are used to examine the impact of ANet on teachers’ data-based instructional practices and the mediating roles of instructional leadership, professional and achievement cultures, and teacher attitudes and confidence. Survey results showed an impact of ANet on the frequency with which teachers’ reviewed and used data, but not their instructional planning or differentiation. Consistent with the program model, ANet had a modest impact on school-mean teacher ratings of their leaders’ instructional leadership abilities and school culture, but no impact on individual teachers’ attitudes toward assessment or confidence with data-based instructional practices. Therefore, it was not surprising that these school and teacher characteristics only partially accounted for ANet’s impact on teachers’ data practices. Interview findings were consistent. Teachers described numerous opportunities to review students’ ANet assessment results and examples of how they used these data (e.g., to pinpoint skills on which their students struggled). However, there were fewer examples of strategies such as differentiated instruction. Interview findings also suggested some ways leadership, culture, and teacher characteristics influenced ANet teachers’ practices. Leaders’ roles seemed as much about holding teachers accountable for implementation as offering instructional support and, while teachers had opportunities to collaborate, a few schools’ implementation efforts were likely hampered by poor collegial trust. Teacher confidence and attitudes varied, but improved over the two years; the latter following from a perceived connection between ANet practices and better student performance. However, some teachers were concerned with the assessments being too difficult for their students or poorly aligned with the curriculum, resulting in data that were not always instructionally useful.
