Math & Comprehension Focus

Math Difficulties

On average, students who received instruction in Visualizing and Verbalizing and On Cloud Nine Math achieved significant improvements in math. They made large (statistically significant) standard score changes on all measures. The 20-point percentile increase in Comprehension and significant growth in Computation puts these students within the normal range (25th–75th percentile). (Of the 734 students, the TOMA Computation subtest was computed out of 305 students, the TOMA Story Problems subtest out of 333 students, the GORT Comprehension subtest was out of 694, and the PPVT was out of 700, as a result of missing pre- or retest data.)
