Characteristics of study sample as reported by study author.
The study took place within 3 school districts and across 13 different schools. Two of the school districts were considered to be located in urban fringe areas and the other one was located in a small town. The average district had 63 schools with roughly 41,000 students.
Teachers in the classrooms averaged 11 years of teaching experience (intervention = 8.56; comparison = 12.74) with just under half of the teachers holding a master's degree (33%; 24% in intervention and 44% in comparison). The teachers were mostly female with 81% in the intervention and 78% female teachers in the comparison group. Students in these classrooms were an average age of 11.7; all students were in 6th grade. Fifty-one percent of the students were female (intervention = 52%; comparison = 51%). No other characteristics were reported.
Classrooms in the intervention used the PLATE Achieve Now program. PLATO Achieve Now is a supplemental math curriculum published by PLATO Learning Inc., for teaching students pre-algebra topics in grade 6. Topics instructed include rational numbers in related organizational patterns, proportion and percent, integers, probability, statistics, problem solving, geometry, measurement, and the foundational concepts of algebra I. The program is used by students independently and helps to reinforce math skills. Students are assessed and scores from the assessment are used to place students within different sections. Students work at their own pace on activities identified by the teacher. The program recommends that students use the program at least 30 minutes per day, four days a week, for at least 10 weeks.
Comparison students received business-as-usual.
Intervention classroom teachers received training through web-based meetings and on-line self-tutorials. Teachers also received on-going support throughout the school year. The estimated annual cost, per student, to implement the program was $36. Of that amount 42% was used for license fees and the remaining 58% was used for teacher training and support, technical support, and printed materials and supplies.
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.
