Students learned significantly more when they used Carnegie Learning’s hybrid algebra program — a blend of online and classroom instruction — reports a two-year Education Department study, which used a randomized control group.
There were no significant results in the first year, reports Ed Week‘s Inside School Research.In the second year, students who used Cognitive Tutor Algebra I improved by 8 percentile points. That’s double the amount of math learning most high school students achieve in a year, said Steve Ritter, a founder and the chief scientist of Carnegie Learning, in Pittsburgh.
The improvements were similar across students of different ethnic and socioeconomic background, and high, regular, and low initial math ability, Ritter said. The researchers found similar improvements among participating middle school students—higher-performing math students typically take algebra in 8th grade rather than in high school—though the middle school sample was not large enough to show significant effects in the same way as the high school students.
Usually students worked with the individualized tutorial program for two days a week and spent three days learning in the classroom.
