Understanding Cognitive-Academic Bidirectionality in Math Learning Disabilities
Vanderbilt University
Summary
The goal of this clinical trial is to test the effects of an innovative intervention designed to improve math skills in first graders at risk for math disabilities. The main questions the trial aims to answer are: * Does combining a math word problem solving intervention with a working memory intervention improve math to a greater extent than the same math intervention without cognitive training? * Do the findings provide evidence for bidirectional effects on development? In other words, does working memory support math learning and does math learning support working memory development? Screening for eligibility will take place in two testing sessions. Students who meet the eligibility criteria will be randomly assigned to one of three groups: 1. One treatment group will receive a validated treatment for math word problem solving plus computerized working memory training. 2. Another treatment group will receive the same validated math treatment plus computerized reading instruction. 3. A control group will receive the conventional school math program, including any additional school-provided intervention. Participants in both treatment groups will receive 35 minutes of tutoring three times per week for 15 weeks. Children who are selected to participate in the study will be tested once before this project's intervention begins; twice after intervention starts; twice after intervention ends; and once near the end of second grade to see how long effects last.
Description
The focus of this clinical trial (CT) is an innovative intervention guided by cognitive-academic mutualism theory in which cognitive resources support development of academic competencies while academic learning in turn exercises and strengthens cognitive abilities. The goal of this CT is to test the effects of an innovative intervention designed to improve cognitive ability and academic skill in coordinated fashion and test bidirectionality as a mechanistic process by which effects occur, thereby evaluating the potential for cognitive-academic mutualism to expand the framework for learning di…

Interventions
- BehavioralCoordinated Treatment
Coordinated Treatment provides 15 weeks (3 35-minute sessions per week) of intervention. Each session comprises 2 components delivered contiguously by the same tutor: 15 min of working memory training, immediately followed by 20 min of math (arithmetic \& word-problem solving)intervention. Explicit transfer instruction is woven into both components.
