Project: Data-based decision-making in schools: Examining the process and effects of teacher support

This project focused on the idea of data-based decision-making (DBDM) at the classroom level, focusing on how teachers use assessment data to adapt their instruction to students’ individual needs. The present project investigated this idea directly and evaluated the effectiveness of teacher support on the different steps of this process. This project utilized longitudinal data of N = 120 teachers and their N = 2458 students, which were used to assess the relations between teachers’ log-file-based data analysis activities, teachers’ self-reported frequency of instructional decision-making, and students’ learning progress in reading by means of latent mediation analyses.
