The study was conducted in four “regular paced” sixth-grade math classes in a suburban middle school located in Wilmington, Delaware. The study occurred in the 2006–07 school year.
Sample characteristics are only reported for the randomized sample. Approximately 62% of this sample qualified for free or reduced-price meals, approximately 54% were female, 43% were Black, 33% were Hispanic, and 21% were White. No students were classified as special education students or English language learners. The analytic sample included 38 Accelerated Math® students and 32 DPFW students.
Intervention students used Accelerated Math® as a supplement to their class’s existing math curriculum for an entire school year. Students typically worked on pencil-and-paper math assignments generated by Accelerated Math® for the first 15–20 minutes of class each day. Accelerated Math® generated a list of problems for each student based on their prior assignment performance. In addition to the daily practice problems, teachers provided mini-review lessons and administered in-depth exercises and tests produced by Accelerated Math® as needed. The study did not specify which version of Accelerated Math® was used.
Comparison students used DPFW as a supplement to their class’s existing math curriculum for an entire school year. Students typically worked on DPFW math assignments selected by the teacher for the first 15–20 minutes of class each day. Assignments were completed with pencil and paper in a workbook. All students worked on the same problems, which were posted on the board by the teacher each day. Teachers selected problems for the class to reinforce previously worked on concepts, or to complement concepts students were currently learning. Students worked individually or in groups on math problems, and students presented their solutions to problem sets in the last 5 minutes of the assigned time.
According to the study author, one of the study teachers used Accelerated Math® prior to the study, while the other had not. Neither teacher had previously used DPFW. The teachers received training on each program prior to the study pretest; however, no details about the training were provided. A substitute teacher took over one teacher’s classrooms for 2 months during the study. The substitute was supported by the regular classroom teacher via daily telephone calls and weekly class visits.

An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
