The Effect of Tablet Computers on Student Achievement: Analyzing the Crucial Role of Teaching Effectiveness in a Randomized Trial

This study examines the effect of one-to-one tablet computer infrastructure on students' learning achievement in German and mathematics, as well as the role of perceived teaching quality in this process. Drawing upon data from the tabletBW project, the research investigates how equipping students with tablets is associated with their performance in reading comprehension, orthography, and mathematics, and how this association is moderated by students' perceptions of teaching quality (encompassing student support, cognitive activation, and classroom management). The study's hypotheses suggest small positive effects of tablets on student achievement and moderate associations between high-quality technology-enhanced teaching (TET) and student achievement. Furthermore, it posits a synergistic interaction between technology (i.e., one-to-one tablet infrastructure) and the quality of TET.
