^aAdd decimal to each number (e.g., 59 is .59).

^bTreat is treatment condition, where 1=conventional instruction on word problems and 2=validated SBI on word problems.

^cThe correlation between treatment condition and the dimensions of pretreatment performance were set to zero, given random assignment to treatment.
