Setting
The study was conducted in 47 schools in 24 states (Alabama, Arkansas, California, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Massachusetts, Michigan, Minnesota, Missouri, Montana, New Mexico, Ohio, Oklahoma, Oregon, Pennsylvania, Tennessee, Texas, Virginia, Washington, and Wisconsin). The authors did not report whether all schools and states were represented in the middle school (grades 6–8) sample.
Study sample
The initial study sample included 2,397 students (1,319 treatment and 1,078 comparison) in grades 3–10 during the 2001/02 school year from 125 classrooms (67 treatment and 58 comparison) in 47 schools in 24 states. The middle school analysis sample in this review included 475 grade 6–8 students (235 treatment, 240 comparison) in 25 classrooms (13 treatment, 12 comparison). Of the students, 43% were male (43% treatment, 43% comparison), and 49% female (48% treatment, 51% comparison). Of the total student gender, 7% were reported as unspecified (8% treatment, 6% comparison). Of the students, 0% were Asian (0% treatment, 0% comparison), 1% African-
American (1% treatment, 0% comparison), 9% Hispanic (9% treatment, 9% comparison), 0% Native American (0% treatment, 0% comparison), 44% White (38% treatment, 49% comparison), and 46% were reported as unspecified (51% treatment, 42% comparison).
Intervention Group
Students were taught by teachers using Accelerated Math during the spring semester of the 2001/02 school year. A progress-monitoring software program, Accelerated Math can be used with teachers’ existing math curriculum. The program tracks students’ daily activities, provides immediate feedback to students and teachers, alerts teachers’ to students struggling with certain assignments, and monitors student achievement. Teachers assigned to the Accelerated Math treatment group were asked to use the program with their existing math curriculum.
Comparison Group
Teachers assigned to the comparison group did not use Accelerated Math but continued their usual math curriculum and practices.
Outcome descriptions
Using a computer adaptive test of math achievement (STAR Math), students were pretested in January 2002 and posttested in May 2002.
Support for implementation
Intervention teachers participated in a one-day training session conducted by Renaissance Learning. The training was designed to familiarize teachers with Accelerated Math and to guide them in integrating it into curriculum and instruction. Of 68 treatment group teachers in the full sample, 66 attended the training.
