Abstract: | One hundred ninety third through sixth graders were given either 6, 16, or 26 months of reading instruction with functional color components (FCC) of parts of words. Another 160 children in the same schools did not receive FCC instruction. The results showed that: (a) FCC brought about improvement in reading scores for disability and nondisability children, (b) increasing months of FCC did not bring accelerated improvement in rate of reading, and (c) nondisability children showed greater improvement than did disability children from FCC. |
