Study Details

Setting

This study was supplemental tutoring for first graders at risk for math difficulties. It took place in an urban district in the Southeastern part of the United States. Researchers recruited 40 schools and 233 first-grade classes across four years.

Study sample

Of the 401 first grade students included in the sample, 49 percent of the sample was female. 70 percent of the sample was black, 20 percent was white, 6 percent was Hispanic, and 4 percent was Other. 14 percent of the sample had an identified disability and 86 percent were eligible for subsidized lunch. Students whose teachers identified them as not speaking English were excluded from the study.

Intervention Group

Galaxy Math + speeded practice is the intervention condition. Galaxy Math included a number sense intervention for 25 minutes that focused on understanding magnitude, equal sign understanding, number-after principle, addition and subtraction subsets, number families, magnitude comparisons, number line representations, and inverse relationship between addition and subtraction. The speeded practice included flashcards where students had to meet or beat their scores on addition and subtraction flashcards that coincided with what was being worked on in the 25 minute Galaxy Math lesson. Tutoring occurred for 16 weeks, 3 times per week, 30 min per session.

Comparison Group

Students in the comparison condition received business as usual instruction and did not receive any tutoring from the research team.

Support for implementation

Tutors received an initial two-day training and participated in weekly meetings, where they received support during the 16-week intervention period. In these weekly meetings, tutors provided an update on each student and discussed challenges with other tutors and researchers. The group also reviewed upcoming topics and materials.
