Speech or Language Impairment (SLI)—Decoding
On average, students with prior SLI diagnoses with decoding difficulties who received Seeing Stars instruction achieved significant improvements in reading. They made large (statistically significant) standard score changes on all measures. Vocabulary was not a targeted measure of instruction. Additionally, the significant increases in Symbol Imagery (orthographic processing), Word Attack, and Word Recognition led to gains in Written Language Comprehension that entered the normal range (25th-75th percentile).
