Learning Morphological and Phonological Spelling Rules: An Intervention Study

Abstract We looked at the effects of teaching 7- and 8-year-old children morphological and phonological distinctions. Some of those given morphological training and some of those given phonological training were also taught how to represent these distinctions in writing. All 4 intervention groups did better than the control group in a standardized test of reading after the intervention. There were gains in children's use of morphological spelling rules but not in their use of conditional phonologically based spelling rules. The improvement in the use of morphological rules in spelling was confined to groups trained in morphology. Training in phonology also had a beneficial effect on the use of morphology in reading. The results are interpreted within the framework of a dual-route model of learning to read and spell.
