Here is my Yule time gift to my fellow reading nerds:

I am honored that a version of my blog post about my shift in thinking on phonemic awareness has been published in the latest Nomanis. Do check out this newer version for the research goods. And a big thank you to Tiffany Peltier for pushing my thinking on the matter and sharing much of the research that I cite in that piece. Check out her blog for sound guidance on phonemic awareness instruction.

Along with this criticism against phonological awareness practice without letters, two recent pieces have addressed critiques against David Kilpatrick’s “phonemic proficiency hypothesis” and against advanced phonemic awareness in general as well:

  • Tim Shanahan’s blog post, “RIP to Advanced Phonemic Awareness,” in which he lays out the state of research alongside of a conversation directly with David Kilpatrick, and two important takeaways emerge: 1) Kilpatrick no longer uses the terminology “advanced phonemic awareness” himself, and instead uses “phonemic proficiency”; and 2) Kilpatrick’s “phonemic proficiency” hypothesis remains just that, and still needs to actually be tested. Oh, and also, read the comments on this post. A number of researchers add their thoughts on this, and Kilpatrick himself jumps in to address some of their points.
  • In addition to that post, a pre-print pushes the conversation yet further in “They Say You Can Do Phonemic Awareness Instruction “In the Dark”, But Should You? A Critical Evaluation of the Trend Toward Advanced Phonemic Awareness Training.” In this piece, the “empirical and theoretical basis for advanced phonemic awareness training” is evaluated and they find that “at present, there is no evidence that targeting phonemic awareness separate from print differentially benefits reading skills over integrating phonemic awareness activities with letters.”
  • UPDATE 2/10/22: David Kilpatrick, Louisa Moats, and others posted a response to the Clemen’s et al. pre-print and gave some pretty poignant critiques that tell us we should wait to read the peer-reviewed version before drawing any firm conclusions. Main takeaway: phonemic proficiency is about orthographic mapping, not decoding.
  • UPDATE 2/25/22: Clemen's et al. posted a rebuttal to Kilpatrick et al.'s response
  • UPDATE 10/1/23: I think it's important to highlight that the Clemens et al. remains a pre-print and has not yet been published after peer review, to my knowledge. This further suggests the pre-print should be taken with a strong grain of salt. If and when it does make it through peer review, please let me know so I can update it here.

To continue on the phonological tip, David Share, most well known for his “self-teaching” hypothesis of reading, also has a recent piece, Common Misconceptions about the Phonological Deficit Theory of Dyslexia that provides some further food for thought on the relation of phonology to print and to dyslexia. There’s a lot of interesting tidbits in this paper — one of the takeaways I had was the insight that dylexia only becomes “‘visible’ in literate societies.” In a pre-literate world, we didn’t need to recall “addresses, telephone numbers, the days of the week or months of the year, foreign names and places,” for example, so spoken-language phonological weaknesses may have existed, but don’t surface until the sub-lexical work needed for print. In other words, the “phonemic awareness” problem children with dyslexia have isn’t just about phonemic awareness, it is related to a phonological issue that only becomes most evident in the demands of phonemic awareness required for reading with an alphabetic system.

He also has a great passage on learning the “infrastructure of the orthography”:

“In addition to learning the specific symbol-sound mappings of the orthography being learned, the learner must “get inside words”, go below the level of meaning and penetrate their sound structure. This phonological analysis or “meta-linguistic” awareness is an inescapable pre-requisite for literacy learning enabling the learner to exploit the combinatoriality of writing, decipher novel letter strings, match up spellings and pronunciations, and begin the process of building the orthographic lexicon by unitizing or chunking sub-lexical symbols into higher-order meaning units—the key to rapid automatic word recognition. It follows that any difficulties that a novice reader may have in processing speech sounds (e.g., hearing loss) or difficulties (in the absence of hearing impairment)) in processing the nuances of phonology (speech sound disorder, dyslexia) will almost invariably impair learning to read. Here, the evidence is incontrovertible and goes well beyond phonological awareness to early pre-literate spoken language competencies in processing (receptive and expressive) the sounds of speech as discussed earlier. Phonology, therefore, is necessarily a major source of variability in reading ability and hence a core deficit (or at least one core deficit) among struggling readers whether dyslexic or non-dyslexic.” [bold added]

There’s much more to say on phonemic awareness — David Share has another recent piece in ILA, Is the Science of Reading Just the Science of Reading English? well worth unpacking, but I’ll leave that for a separate post.

Also worth spending your time investigating — I highly recommend watching all three of Mark Seidenberg and Molly Farry-Thorn’s Miniseries on Phonemes and Phoneme Awareness. I found the first two especially enlightening and clarifying.

Enjoy geeking out in between some grog, coquitos, and COVID minimal family time, and wishing you a most restful and restorative break.

I have somewhat eclectic book reading habits, and I take pleasure in reading haphazardly (i.e. whatever I happen to come across). After growing bored with Moby Dick recently, I happened across a copy of Siddhartha Mukerjee’s The Emperor of All Maladies: A Biography of Cancer.

The book is compellingly written, narrating an expansive overview of the history of the treatment of cancer, while at the same time painting portraits of individual researchers, clinicians, and patients that draws the reader in. It makes oncology research and clinical practice sound exciting, which is no small feat.

In another post, I wrote about the riches of Speech-Language Pathology and what this domain of research and practice has to offer for all educators.

I'd also like to highlight that relatedly, the American Speech-Language-Hearing Association (ASHA) and it's publications has a lot to offer to those of us getting into the Science of Reading.

Let me just give you a recent example: the “JSLHR Research Symposium Forum: Advances in Specific Language Impairment Research and Intervention” offers some really interesting and useful open access research. Here's some tidbits:

  • There's a useful overview of dyslexia and DLD/SLI from Suzanne Adlof that stresses the need to screen and diagnose language for students who have demonstrated word reading problems because DLD and dyslexia often co-occur

“Considering the frequent comorbidity of dyslexia and SLI, all school-aged children who are identified with word reading problems should receive a thorough language evaluation.” —Suzanne Adlof

  • Spaced retrieval practice has gotten a lot of attention from ResearchEd type folks over the last few years (as it should), and so this piece on its benefits to word learning for students with SLI will be further reaffirming.

  • I found this one by Pamela Hadley on “Exploring Sentence Diversity at the Boundary of Typical and Impaired Language Abilities” especially useful, as while I am fully invested in explicit sentence-level instruction, I sometimes struggle to know exactly what to investigate and unpack in a sentence beyond the basics. In this paper, Hadley provides a neat way to think of linguistic development at the sentence-level:

”...as a series of four developmental steps: words, verbs, childlike sentences, and adult sentences.”

What she also highlights is how important verbs are as a developmental stage, given the complexity of the function of verbs in a sentence:

“Verbs carry information about the number of participants in an event and the semantic roles of those participants.”

And much more in there to think about!
