Sarama, Julie; Clements, Douglas H.; Wolfe, Christopher B.; Spitler, Mary Elaine – Journal of Research on Educational Effectiveness, 2012
We used a cluster randomized trial to evaluate the effectiveness of a research-based model for scaling up educational interventions, focusing on the persistence of effects with and without a follow-through intervention. The instantiation of the Technology-enhanced, Research-based, Instruction, Assessment, and professional Development (TRIAD) model…
