The spelling's the thing: Knowledge of derivational morphology in orthography and phonology among older students

Abstract

ABSTRACTThis study examines the ability of good and poor spellers at grades six and ten to generate orthographic and phonetic derivatives for three predominant vowel alternation patterns characteristic of internal derivational morphology. Results support the hypothesis that a productive knowledge of these patterns in orthography precedes a productive knowledge of these patterns in phonology. Further, orthographic (visual) information was found to be superior to phonetic (aural) information in accessing the appropriate derivational morphological rules. An order is identified for the acquisition of a productive knowledge of the three vowel alternation patterns in both orthography and phonology. Based on these results and analyses, instructional implications for both spelling and vocabulary are offered.
