Creating effective learning environments remains a critical challenge in education, particularly in addressing the persistent inequalities in student outcomes. Despite the potential of teacher professional development (PD) programs to enhance classroom instruction and student achievement, traditional one-off PD workshops often yield limited effects. This study aims to evaluate an innovative approach to PD through the ‘High Touch High Tech’ (HTHT) model, combining technology-driven personalized learning with teacher-facilitated, project-based classroom experiences.
The study draws on the Technology Acceptance Model (TAM) to explain the adoption and use of the HTHT approach by teachers and students. TAM posits that perceived ease of use and perceived usefulness are key factors that drive the acceptance and effective integration of technology, and this research explores how these factors influenced teachers’ engagement with digital adaptive learning tools and how students benefited from the personalized learning experience.
Using a clustered randomized controlled trial in Uruguay, we assess the HTHT model’s impact on teacher effectiveness and both cognitive and non-cognitive outcomes. Our study involved 99 schools, 114 teachers, and 2,002 5th-grade students across treatment and control groups.
Findings show a significant increase (47%) in individualized use of the digital learning platform among students in the HTHT intervention. Students in the treatment group demonstrated improved math performance (0.33 SD, p < 0.001), with gains linked to higher completion rates of episodes in the digital platform. Importantly, students benefitted equally from the HTHT interventions, regardless of their individual student characteristics (initial achievement, gender, father’s education) and school characteristics (school types, school quintile).
This study contributes to the discourse on how technology and innovative teaching practices can improve educational outcomes, highlighting the synergistic value of integrating technology with active learning strategies. The potential of HTHT as a scalable model for improving student outcomes in diverse contexts will be discussed.
