The Effectiveness of a Color‐Coded, Onset‐Rime Decoding Intervention with First‐Grade Students at Serious Risk for Reading Disabilities

Abstract

This study was an investigation into the effectiveness of a color‐coded, onset‐rime–based decoding intervention with first‐graders at serious risk for reading disabilities using a single‐subject multiple probe design. Students increased their ability to decode instructional words on average 73% over baseline. For novel words from instructed rime patterns, scores increased by an average of 56%. Transfer at the vowel level to uninstructed rime patterns was limited, with scores improving by an average of 29%. Students maintained decoding gains at 1‐week and 1‐month maintenance. While acknowledging the difficulty in predicting reading disabilities based on first‐grade performance, the effectiveness of the early intervention is a promising step in finding an instructional approach that is successful with the most at risk or disabled students who often do not respond to effective remedial programs.
