Description

In the studies contributing to the WWC report, the program was delivered in low-dosage, repeated circle-time sessions rather than as a separate curriculum block. Teachers implemented sessions "for approximately 20 minutes during circle time," and "The Red Light, Purple Light sessions took place twice a week for 8 weeks." Teachers implementing the sessions received a 3-hour in-person training and a developer-provided kit of materials; comparison teachers received no program training.

Design Implications
