Summary
The main purpose of this clinical trials is to explore short-term effects of coordinated intervention versus the business-as-usual school program on the primary endpoints of post-intervention word-reading fluency and arithmetic fluency. The study population is students who begin 1st grade with delays in word reading and calculations. Students who meet entry criteria are randomly assigned to coordinated intervention across reading and math, reading intervention, math intervention, and a business-as-usual control group (schools' typical program). The 3 researcher-delivered interventions last 15 weeks (3 sessions per week; 30 minutes per session). Students in all 4 conditions are tested before researcher-delivered intervention begins and after it ends.
