Latest / The Reading Instruction Show / Orthographic Mapping: Weak or Robust Theory?
Transcript
- 0:00This is The Reading Instruction Show. I'm your
- 0:03host, Dr. Andy Johnson. Topic of today's podcast
- 0:07is orthographic mapping. Let's see if we can
- 0:13learn a thing or two. Now, orthographic mapping
- 0:18is a term invented by Linnea Erie. So let's start
- 0:23with her definition. Quote, orthographic mapping
- 0:27occurs when in the course of Reading specific
- 0:31words, readers form connections between written
- 0:35unit, either single grapheme or larger spelling
- 0:38patterns, and spoken units, either phonemes,
- 0:42syllables, or morphemes. These connections are
- 0:45retained in memory, along with meanings, and
- 0:49enable readers to recognize words by sight. An
- 0:52important consequence of orthographic mapping
- 0:55is that the spellings of words enter memory and
- 1:00influence learning, the processing of phonological
- 1:04constituents in words, and phonological memory
- 1:08unquote. 2014, page 5 and 6. Now this is written
- 1:15with all the stunning clarity of a Rorschach
- 1:19inkblot test. So let's do a little on Packer
- 1:2218 here. Orthography has to do with symbols representing
- 1:29sounds and the arrangement of letters. The written
- 1:34language that you read is an orthographic system.
- 1:39You're putting sound symbols together to create
- 1:43words. Other written language systems use symbols
- 1:47to represent things. These are called logographic.
- 1:53A logo is a symbol representing a thing. So here
- 1:58you're putting symbols together to create meaning.
- 2:03Now mapping in a cognitive sense refers to how
- 2:07things are stored or connected in long -term
- 2:10memory. And orthographic mapping, as stated above,
- 2:15and I'll try to make it a little clearer, orthographic
- 2:19mapping, according to Airy, is the cognitive
- 2:22process by which readers store written words
- 2:25in long -term memory. Airy calls these stored
- 2:30words sight words. And readers are said to be
- 2:34able to effortlessly retrieve these and use them
- 2:38to recognize words during reading. Orthographic
- 2:43mapping makes letter -sound connections and bonds
- 2:47these to the spelling, punctuation, and meaning
- 2:50of words in long -term memory according to the
- 2:54theory of Linnea Erie. And the last term is upward
- 3:01lexical repurposing. Upward lexical repurposing.
- 3:05is when important -sounding words are combined
- 3:09to make non -things sound like important things.
- 3:14And research is showing that upward lexical repurposing
- 3:17significantly enhances one's ability to get grants,
- 3:22book contracts, consulting jobs, and large speaking
- 3:25fees. And orthographic mapping is an example
- 3:29of this. So it all makes sense, yes? If knowledge
- 3:34was stored in long -term memory in the form of
- 3:38words, orthographic mapping might make a bit
- 3:42of sense. But knowledge is stored in the form
- 3:46of associative networks, not words. Things in
- 3:52long -term memory are connected to and organized
- 3:55around related things. Any mapping that takes
- 4:01place is primarily semantic mapping. For example,
- 4:07when you hear the word cat or see the word cat
- 4:10in print, you automatically associate it with
- 4:14cat things. Soft, purry, paws, kitty, pet. These
- 4:19things are closely related to cat. The neural
- 4:23pathways leading to these things are activated.
- 4:28things come to mind. Now what is not activated
- 4:32when you hear the word cat? You don't automatically
- 4:37think of short a words or cvc words or the at
- 4:41phonograms. You don't think about letter sounds
- 4:44or letter patterns. You think of things. Clearly
- 4:50we have access to semantic information when we
- 4:54see the word cat in print. Yes, there is orthographic
- 5:00information on the page and some form of orthographic
- 5:05mapping is stored in the head, but semantic information
- 5:10takes precedent over orthographic information.
- 5:16And if we just walked around recognizing individual
- 5:19words floating in space, then the theory of orthographic
- 5:24mapping would make a bit of sense. But semantic
- 5:30connections between words in long -term memory
- 5:33are much stronger than any orthographic connections.
- 5:39And reading is primarily a meaning -making process,
- 5:42not a word recognition process. So orthographic
- 5:48mapping may be a thing, but semantic mapping
- 5:52is much more of a thing. Now let's take a look
- 5:57at orthographic facilitation. Orthographic facilitation
- 6:02means seeing the spelling of words as you are
- 6:05learning them. Now this is another example of
- 6:10upward lexical repurposing. Airy said, orthographic
- 6:16facilitation improves vocabulary, learning, and
- 6:20spelling. In a 2017 study with 45 first grade
- 6:25students, she compared their memory of two novel
- 6:31sets of words. Now the first set, and I'm just
- 6:34giving you a brief overview, the first set contained
- 6:39just pictures of the novel word and along with
- 6:42a spoken definition. The other set contained
- 6:46pictures with the names of the word printed underneath.
- 6:51followed by a spoken definition. After two weeks,
- 6:56children were shown the pictures and asked to
- 6:59remember the word associated with it and the
- 7:02meaning of the word. And it turns out that when
- 7:06the printed word was included in the original
- 7:10exposure with the picture, children remembered
- 7:14the pronunciation of it slightly better. Aerie
- 7:20reasoned that since pronunciation was the most
- 7:24difficult part of vocabulary learning, something
- 7:27I questioned, she reasoned that orthographic
- 7:30facilitation thereby enhanced vocabulary learning.
- 7:36Now, again, in case you missed that, students
- 7:39were able to remember the pronunciation of a
- 7:43word when it was presented with letters, with
- 7:47the word printed. And based on that, they were
- 7:51able to remember the pronunciation. And based
- 7:54on that, she says, ah, it facilitates vocabulary
- 7:56learning. This is an example of a research -based
- 8:01conclusion. You can technically say that orthographic
- 8:06facilitation is a research -based strategy. There's
- 8:10research to indicate it does something, but the
- 8:15research is not very good. and the something
- 8:18it does is not really indicative of something
- 8:22else. Remember the pronunciation of a word has
- 8:27very little to do with acquiring the word. Children
- 8:33learn between 3 ,000 and 4 ,000 words a year.
- 8:37By the end of elementary school they know approximately
- 8:4125 ,000 words and by the end of high school approximately
- 8:4550 ,000 to 80 ,000 words. And how much orthographic
- 8:49facilitation was taking place here? Children
- 8:54learned the vast majority of words with no orthographic
- 8:58facilitation. They learned them by hearing them
- 9:02used in conversation or by seeing the words in
- 9:07print. In the study above, when children had
- 9:11letter clues as they were learning the pronunciation
- 9:14or sound of the word, they were better able to
- 9:17remember the sound of the word when compared
- 9:21to having no letter clues. Yes, absolutely. Seeing
- 9:26sound symbols as you're learning the sound of
- 9:30a new word provides another modality for remembering
- 9:34the sound of the word. And if you have a visual
- 9:39representation of that sound while you're learning
- 9:41the pronunciation, chances are that you're better
- 9:46able to remember the pronunciation. Most people
- 9:49could have told you that up front. So, orthography
- 9:54and vocabulary learning. This is a 2008 study,
- 10:00Rosenthal and Airy, and there were two experiments
- 10:02in this article. The first one was conducted
- 10:05with 20 second grade students. They were given
- 10:08two sets of low frequency CVC nouns, 12 words
- 10:14total. One set was taught with the word given
- 10:17orally and a picture, and again with the word
- 10:20printed on the picture. The other set was given
- 10:24the word orally, but picture, but no word on
- 10:27it. Vocabulary learning was determined by assessing
- 10:32students' ability to remember the pronunciation
- 10:36of the words and their meaning. It was found
- 10:41that these students could remember the pronunciation
- 10:45and meaning of words better when it was accompanied
- 10:48by seeing the spelling of the word. The second
- 10:52experiment was similar but was conducted with
- 10:5532 fifth grade students and 20 words. And after
- 10:59one day, vocabulary learning was assessed with
- 11:02an oral close task, remembering the word definitions
- 11:06and meaning, and to see if they could spell the
- 11:08words. Seeing the word while learning it improved
- 11:12their memory of spelling, pronunciation, and
- 11:15meaning of these 20 words. The results were followed
- 11:21by four pages of general discussion in this research
- 11:25article to draw logical conclusions based on
- 11:28the data. And the authors concluded that, quote,
- 11:31elementary school students learned and remembered
- 11:34the pronunciation and meanings of new vocabulary
- 11:37words better when they were exposed to written
- 11:40forms of the word during study periods than when
- 11:43they only heard and repeated the words, unquote.
- 11:49And this is why you must evaluate A sample size
- 11:54of 20 in one experiment asks students to remember
- 11:5812 words, and 32 in the other group asks students
- 12:02to remember 20 words. But one could hardly generalize
- 12:07to elementary school students in general based
- 12:10on this. But the larger point is that this is
- 12:15a remembering experiment, not a vocabulary learning
- 12:20experiment. Yes, if you provide an additional
- 12:26variable, seeing the spelling of the word, this
- 12:30will likely enhance students' ability to remember
- 12:33the pronunciation and meaning of the word. But
- 12:37it doesn't mean that orthography provided a mnemonic
- 12:43device that tied the spelling of words to the
- 12:46pronunciation and memory. It does not mean that
- 12:49spelling became bonded to word pronunciations
- 12:52and meaning as Airy tries to explain. It just
- 12:56means that this group of students remembered
- 12:59things better when you included spelling. And
- 13:04I would posit that if you had students do a little
- 13:08dance as they learned one set of words, the dance
- 13:11set would show similar results. And this does
- 13:16not mean that word learning is tied to dance.
- 13:20It just means that when you present multiple
- 13:23forms of data with a thing, or if you're more
- 13:27engaged with the thing while learning, that thing
- 13:30is more easily remembered. This has been The
- 13:35Reading Instruction Show. I'm your host, Dr.
