Study Details
Setting
The study was conducted in nine elementary schools in an urban school district in Tennessee.
Study sample
The sample for this study included a total of 120 students in the second, third, and fourth grades: 40 low-performing students with learning disabilities, 40 low-performing students without learning disabilities, and 40 average-performing students. This report reviews findings for only the 40 students with learning disabilities. The study design was a randomized controlled trial conducted in nine elementary schools. Teachers who had one or more students with learning disabilities in their math class were recruited to participate in the study. The recruitment efforts resulted in a sample of 40 teachers who were randomly assigned to either PALS or comparison conditions (20 teachers per group). Each of the 40 teachers was asked to identify three students to participate in the study: one low-performing student with a learning disability (identified in accordance with state regulations), one low-performing student who did not have a learning disability, and one average-performing student. Teachers were not informed of their treatment assignment until after they had selected students to participate in the study. There was no attrition of schools, teachers, or students.
Intervention Group
PALS was conducted twice weekly in math classes for 25- to 30-minute sessions for 23 weeks. Students were trained to be PALS tutors and tutees in five 30-minute sessions during the week prior to the start of the intervention. Pairs changed every two weeks. Any student who had not been a tutor for the past four weeks was assigned a tutoring role so that within every six-week interval, each student served as a tutor for at least two weeks.
Comparison Group
Comparison teachers conducted math classes using their normal approach (business-as-usual).
Outcome descriptions
The mathematics domain was assessed with two mathematics achievement measures at pretest and posttest. The Tennessee Mathematics Operations Test–Revised samples problems across the first through sixth grades from the Operations portion of the Tennessee state curriculum, whereas the Tennessee Mathematics Concepts and Applications Test samples problems from the Concepts/Applications portions of the curriculum. For a more detailed description of these outcome measures, see Appendix B.
Support for implementation
PALS teachers were trained at a full-day workshop at which they learned both about PALS procedures and how to train their students on PALS. At the end of the workshop, teachers were given a PALS manual that included scripted lessons to be used when conducting student training.
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.
For more, please see the WWC Glossary entry for improvement index.
An outcome is the knowledge, skills, and attitudes that are attained as a result of an activity. An outcome measures is an instrument, device, or method that provides data on the outcome.
A finding that is included in the effectiveness rating. Excluded findings may include subgroups and subscales.
The sample on which the analysis was conducted.
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 number of students included in the analysis.
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.
