Motivation and self-teaching with morphology

Listen to three of the most important voices in literacy, Linnea Ehri, Peter Bowers and Kenn Apel, talk about the important role of morphology in reading, vocabulary, spelling and sight word development. 

Linnea Ehri updates her theory of orthographic mapping to emphasize the role that morphology plays not just in the four initial phases but when words are stored in sight word memory directly - without needing to be sounded out. The spelling of morphemes is critical to developing sight words and becomes the predominate way that words enter sight word memory. She points out that morphemes - the meaningful core of every word - have consistent spelling patterns that help readers resolve sound-symbol conflicts and is critical for learning so-called irregular words like go, goes, gone, do, does, done and say, says and said.

Ehri credits Peter Bowers and Sue Hegland, author of Beneath the Surface of Words, for helping her understand the role of morphology in orthographic mapping. Pete and Kenn Apel then enter the discussion, clarifying what morphology is and how it influences spelling, word meaning and vocabulary growth.
