Jenkins, Jade Marcus; Watts, Tyler W.; Magnuson, Katherine; Gershoff, Elizabeth T.; Clements, Douglas H.; Sarama, Julie; Duncan, Greg J. – Journal of Research on Educational Effectiveness, 2018
Prior research shows that short-term effects from preschool may disappear, but little research has considered which environmental conditions might sustain academic advantages from preschool into elementary school. Using secondary data from two preschool experiments, we investigate whether features of elementary schools, particularly advanced…

Watts, Tyler W.; Clements, Douglas H.; Sarama, Julie; Wolfe, Christopher B.; Spitler, Mary Elaine; Bailey, Drew H. – Journal of Research on Educational Effectiveness, 2017
Early educational intervention effects typically fade in the years following treatment, and few studies have investigated why achievement impacts diminish over time. The current study tested the effects of a preschool mathematics intervention on two aspects of children's mathematical development. We tested for separate effects of the intervention…

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…

Klein, Alice; Starkey, Prentice; Clements, Douglas; Sarama, Julie; Iyer, Roopa – Journal of Research on Educational Effectiveness, 2008
Research indicates that a socioeconomic status-related gap in mathematical knowledge appears early and widens during early childhood. Young children from economically disadvantaged families receive less support for mathematical development both at home and in preschool. Consequently, children from different socioeconomic backgrounds enter…

Sarama, Julie; Clements, Douglas H.; Starkey, Prentice; Klein, Alice; Wakeley, Ann – Journal of Research on Educational Effectiveness, 2008
This study used a randomized field trial design to evaluate the efficacy of a research-based model for scaling up an intervention focused on preschool mathematics. Although the successes of research-based educational practices have been documented, equally well known is the paucity of successful efforts to bring these practices to scale. The same…
