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 22-point percentile increase in Comprehension (not graphed) and significant growth in Computation puts these students within the normal range (25th–75th percentile). (Of the 681 students, the TOMA Computation subtest was computed out of 271 students, the TOMA Story Problems subtest out of 300 students, the GORT Comprehension subtest was out of 642, and the PPVT was out of 647, as a result of missing pre- or retest data.)
