Characteristics of study sample as reported by study author.
| Black | 100% |
This study took place at one suburban high school in Maryland, near the Washington, DC area. The majority of students in the high school were Black. The school is located in a suburban county with a population of approximately 764,000. The author reported that residents in this county have an Effective Buying Income (EBI) that is 17% higher than the average US EBI.
All 60 students in the sample were high school seniors. The sample of students included 26 males (43%) and 34 females (57%), all of whom were Black. No other demographic characteristics specific to the study sample were reported.
Students were randomly assigned to participate in either The Stanford Study Guide for the SAT or Davidson’s Your Personal Trainer for the SAT. Intervention group students were excused from their regular classroom three times per week for 1 hour to use the test preparation programs. During this time, students would go to the computer lab, where they worked with one of the two computer coaching programs. Students receiving the intervention spent 26 hours with the program over the course of 9 weeks.
Students in the comparison group were not offered the computerized coaching programs and continued with their curriculum in their regular classrooms. These students took the SAT at the same time as the intervention students, both at pretest and posttest.
No information was provided regarding support for implementation.
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.
