The high/scope preschool curriculum comparison study through age 23

This study assesses the relative effects through age 23 on young participants born in poverty of the High/Scope, Direct Instruction, and traditional Nursery School preschool curriculum models. At ages 3 and 4, 68 children were randomly assigned to the models, which were implemented independently and to high standards, in 212-hour classes 5 days a week and biweekly 112-hour home visits. For a decade, virtually no curriculum group differences in intellectual and academic performance were found. In many areas, no statistically significant differences were found at age 15 or at age 23; however, a pattern of group differences in community behavior did emerge at age 15 and became more pronounced at age 23. At age 15 the Direct Instruction group reported committing 212 times as many acts of misconduct as the High/Scope group. At age 23, compared to the other curriculum groups, the Direct Instruction group had three times as many felony arrests per person, especially those involving property crimes; 47% of the Direct Instruction group was treated for emotional impairment or disturbance during their schooling, as compared to only 6% of either of the other curriculum groups. These results are attributed to the emphasis on planning, social reasoning, and other social objectives in the High/Scope curriculum and the Nursery School curriculum, but not in the Direct Instruction curriculum. The results of this study do not consistently distinguish between the long-term effectiveness of the High/Scope and traditional Nursery School currculums, but the High/Scope curriculum model is more readily replicated because of its more precise definition. These findings argue against using Direct Instruction in preschool programs and for using a well-defined curriculum model based on child-initiated learning activities.
