Ten schools in Grant Joint Union High School District in Sacramento, California used the I CAN Learn® Algebra and Pre-Algebra courseware during the 2000-2001 school year. A comparison of math performance of 6,157 students in traditionally-taught and I CAN Learn® classrooms showed clear advantages for I CAN Learn® students.

As part of a federal grant evaluation, Dr, Jeffery Oescher of the University of New Orleans examined students' math performance in the Grant Joint Union High School District. Grant Joint Union students who used I CAN Learn® significantly outscored traditionally-taught students on all measures of math achievement at all grade levels. As seen in Figure 1, the typical I CAN Learn® student scored five to eight percentile points higher than the typical traditionally-taught student in the Total Math Battery of the SAT-9.

Normal Curve Equivalent (NCE scores were used in statistical analyses to determine whether score differences were statistically significant. In grades 7 and 8, three separate math scores are reported for SAT-9 - Total Math Battery, Problem Solving, and Procedures. In grade 9, only a Total Math Battery is reported. Differences for the 7th and 8th grade "Procedures" subscales, the 8th grade "Problem Solving" subscale, and all three "Total Math" scales were statistically significant; that is, I CAN Learn® students demonstrated significantly greater computational and problem solving skills than other students. Further, as shown in Figure 2, these differences were found at all grade levels in which I CAN Learn® was implemented.
