Orthographic Mapping: Weak or Robust Theory?
from The Reading Instruction Show
In this podcast, I try to make sense of orthographic mapping, a term invented by Linnea Ehri and introduced in Chapter 15 (Ehri, 2014). We’ll start with her definition: “Orthographic mapping occurs when, in the course of reading specific words, readers form connections between written unit, either single graphemes or larger spelling patterns, and spoken units, either phonemes, syllables, or morphemes. These connections are retained in memory along with meanings and enable readers to recognize words by sight. An important consequence of orthographic mapping is that the spellings of words enter memory and influence vocabulary learning, the processing of phonological constituents in words, and phonological memory” (Ehri, 2014, pp. 5-6) This is written with all the stunning clarity of a Rorschach inkblot. Let’s do a bit of unpack-O-rating.
