"Effectiveness of Cognitive Tutor Algebra I at Scale"
Students who used a mathematics program that blends online learning and in-class instruction in algebra significantly improved their performance in the subject, finds a new federally funded study.
More than 17,000 students and 375 teachers from 147 schools in seven states participated in the two-year study by the RAND Corp. and Educational Testing Service. The randomized, controlled experiment focused on Carnegie Learning's Cognitive Tutor Algebra I.
While the first year showed no significant results, in the second year, the students who were taught algebra through the Carnegie Learning program improved by 8 percentile points.
