Clements, Douglas H.; Sarama, Julie; Wolfe, Christopher B.; Spitler, Mary Elaine – American Educational Research Journal, 2013
Using a cluster randomized trial design, we evaluated the persistence of effects of a research-based model for scaling up educational interventions. The model was implemented in 42 schools in two city districts serving low-resource communities, randomly assigned to three conditions. In pre-kindergarten, the two experimental interventions were…

Clements, Douglas H.; Nastasi, Bonnie K. – Information Technology in Childhood Education Annual, 1999
Reviews studies examining the effects of theoretically-based Logo environments on young children's metacognitive processing and the extent to which sociocognitive processes mediate those effects. Findings suggest that Logo fosters development of metacognitive processing, in part by engendering high-level conflict resolution. Implications are…

Young Children's Representation of Replay: Developmental Staged and Effects of Mediated Computer Environments.
Peer reviewed Peer reviewed
Park, Sunhee; Clements, Douglas H. – Journal of Research in Childhood Education, 1995
Investigated development of ability to recognize, anticipate, and plan the replay of recorded action sequences. Effects of an educational intervention on this ability were evaluated for two- to five-year olds. Results suggest that representational competence is a teachable concept and that a complex mediating structure allows children to…
