The study took place in six public schools in urban and rural settings: three middle schools and one high school in Pennsylvania, one middle school in Minnesota and one middle school in Texas. The intervention took place in a class that met 5 days per week for 45 minutes per day.
The researchers randomly assigned 1,090 students across all participating schools: 619 to the intervention group and 471 to the comparison group. A total of 985 students were included in study in grades 5 through 9. Approximately 55% of the students were female. Thirty percent were Black, 6% were Asian, 5% were White, and 59% did not report race. Forty-four percent were Hispanic or Latino. Students were eligible for the study if they scored between the 25th and 65th percentile on districts’ standardized math assessment in the year before the study.
Students assigned to Computer and Team Assisted Mathematical Acceleration (CATAMA) Lab intervention attended a class using this program 5 days per week, 45 minutes per day, for a full semester or trimester (13–18 weeks). CATAMA is an elective course for students needing additional assistance in math while they continue taking their regular math class. Each class session included whole class instruction, individual and peer-assisted computer instruction and practice, and individual and small group tutoring. Class instruction primarily covered pre-algebra topics and was determined by the instructor based on students' remedial math needs and upcoming topics of instruction in their regular math classes.
Students in the comparison condition took an elective course such as music or art and did not attend the CATAMA Lab course.
Each CATAMA Lab instructor was an experienced math teacher selected by the school. Instructors received an initial day of professional development taught by a university-based Lab facilitator. During the school year, the Lab facilitator visited the Lab once per week to help the instructor become familiar with the computer software, pair students appropriately, and either model or provide feedback on instruction.
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.

The group to which the intervention group is compared, which may include a different intervention, business as usual, or no services.
The timing of the post-intervention outcome measure.

The mean score of students in the intervention group.
The mean score of students in the comparison group.
The WWC considers a finding to be statistically significant if the likelihood that the finding is due to chance alone, rather than a real difference, is less than five percent.

Study findings for this report.
Based on the direction, magnitude, and statistical significance of the findings within a domain, the WWC characterizes the findings from a study as one of the following: statistically significant positive effects, substantively important positive effects, indeterminate effects, substantively important negative effects, and statistically significant negative effects. For more, please see the WWC Handbook.
The WWC may review studies for multiple purposes, including different reports and re-reviews using updated standards. Each WWC review of this study is listed in the dropdown. Details on any review may be accessed by making a selection from the drop down list.
Tier 1 Strong indicates strong evidence of effectiveness,
Tier 2 Moderate indicates moderate evidence of effectiveness, and
Tier 3 Promising indicates promising evidence of effectiveness,
as defined in the
non-regulatory guidance for ESSA
and the regulations for ED discretionary grants (EDGAR Part 77).
