Improving the Academic Performance of First-Grade Students With Reading and Math Difficulty

Vanderbilt University·interventional·Posted Jun 19, 2019·Updated Mar 23, 2026

In Brief

A clinical study evaluating Reading Intervention, Math Intervention, and 1 other intervention for Reading Learning Disability and Math Learning Disability. Completed, enrolled 385 participants across 1 site.

Detailed 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.

Interventions

Reading Interventionbehavioral

Reading intervention provides 15 weeks (3 30-minute sessions per week) of explicit instruction to build skill on letter-sound associations, decoding, sight words, \& contextualized reading.

Math Interventionbehavioral

Math intervention provides 15 weeks (3 30-minute sessions per week) of explicit instruction on number knowledge \& counting strategies to build arithmetic skill.

Coordinated Interventionbehavioral

Coordinated intervention provides 15 weeks (30-minute sessions per week) of explicit instruction addressing the similar skills as in the reading intervention arm \& similar objectives as the math intervention arm.
