Dyslexia – Decoding
On average, students with a prior Dyslexia diagnosis who received Seeing Stars instruction achieved significant improvements in reading. They made large (statistically significant) standard score changes on seven of nine measures. (Vocabulary was not a targeted measure of instruction.) The 20-point percentile increase in Word Recognition put these students well within the normal range (25th–75th percentile). The large average standard score change in Paragraph Reading Accuracy should also be noted.
