Construction and learning to spell

Abstract

Little is known about the way in which children learn the rules of literacy. We argue that children’s learning about orthographic rules can be the result of their own constructions. We provide longitudinal evidence on Greek children’s understanding of the morphophonemic rules for the spelling of the /o/ and /e/ vowel sounds in stems and inflections. These sounds can be spelled with more than one phonetically acceptable grapheme. When the vowel sound represents part of an inflection or the inflection itself, the grammatical status of the word is the key to the right choice between the alternative spellings. In contrast, no such morphemic rule applies when the sound is part of the stem morpheme. The spelling of each of these vowel sounds in the stem must rely on rote learning. Our results suggest that children go through a three-step developmental sequence in learning how to spell /o/ and /e/ in inflections: initially they adopt only one spelling for each vowel sound. Later, when they add the alternative spelling to their repertoire, they overgeneralize it to inappropriate words. Eventually, they restrict the alternative spellings to the grammatically appropriate words. We argue that these overgeneralizations, which have also been found in English, French and Portuguese spelling, indicate that children at first try to extend an existing rule, based on grapheme–phoneme conversion, for the new spelling. This slight change produces new experiences for them which allow them to construct a higher-level morphophonemic spelling rule.
