Print-to-Speech or Speech-to-Print? That is the Question
Teacher question:
I know you typically don’t talk about specific programs, but I really would like to know your thoughts. I had always wanted more training in a structured literacy program/approach. I always thought Wilson, and specifically OG approaches, were the gold standards. More recently, I began reading about programs labeled as speech to print. Proponents of speech to print methods claim it is much faster to teach kids to read (and spell) than OG based approaches. Is there research to support this? Are these studies comparing programs based on OG (that mainly follow a more print to speech approach) and programs that are more specifically speech to print? Thank you!
You’re right that I don’t comment on specific programs. However, I do talk about research on programs or the consistency of certain parts of a program with research.
Let’s start with the claim that Orton-Gillingham (OG) and programs derived from it being the “gold standard.” To me a gold standard program would consistently result in positive learning outcomes and would outperform competing methods. Outperformance would be demonstrated by direct research comparisons, or by meta-analyses summarizing disparate but relevant studies. Gold standard approaches would result, on average, in more learning. If OG is the gold standard, it should reliably do better than other explicit decoding programs.
The National Reading Panel (NRP, 2000) analyzed the effectiveness of phonics across 38 studies that evaluated 18 different curricula. Our conclusion was that phonics added a valuable ingredient to literacy teaching, and that programs with explicit systematic phonics outdistanced those that did not.
What about different types of phonics teaching?
We made some of those comparisons, too. Synthetic phonics (reading words from individual letters and sounds), for instance, had higher average effects than analytic phonics (focused on syllables, morphemes, and use of known words as analogies). This difference wasn’t statistically significant, however. That means those different approaches did equally well.
We didn’t compare individual phonics programs with each other.
There were usually only 1 or 2 studies of each program. Not enough evidence for meaningful comparisons of Phonics Programs A and B. An exception was OG. There were enough of those studies to compute a meaningful estimate of effectiveness, it could have been compared with the rest of the set.
I didn’t push for such an analysis because I feared the results would be misleading. OG often failed but usually with severely disabled – hospitalized – populations. It was clear that OG exerted no miracle impact on those learners, but would any other program have done so? It would be impossible to say.
Over 20 years, more research has accumulated, and OG now has merited its very own meta-analysis (Stevens, Austin, Moore, Scammacca, Boucher, & Vaughn, 2021). That study found OG to be effective but with rather modest benefits – lower effectiveness than for the average phonics study that NRP considered.
So much for being the gold standard! Orton-Gillingham procedures are no more effective than any other explicit systematic phonics instruction – despite the religious fervor of some of its advocates.
Of course, those true believers, argue against these data:
“They didn’t look at the right version of OG.”
“I do it a little differently than others and it really works well for my kids.”
“The newer trainers aren’t as good as the past ones, so they probably studied teachers who weren’t well trained.”
Those complaints aside, there is no reason to think those kinds of things affect OG any more or less than any other program. If it’s that hard to find a potent version, then we shouldn’t expect widespread success. We lack direct comparisons of OG with other phonics approaches, but it looks like it works about as well any (though often it does not do as well as those).
Which moves us on to the second point – the one about speech to print approaches to phonics.
I’ve oft grumbled about the lack of evaluation of individual features of complex instructional programs. Research may affirm the benefits of a program without revealing its active ingredients.
You’d think with all the interest in phonics there would be many such studies exploring the implications of sound tracing, analytic/synthetic approaches, grapheme-phoneme sequences, inclusion of morphological analysis, decodable text, emphasis on consistency versus flexibility, print-to-speech/speech-to-print approaches, dosage variation, and so on.
Unfortunately, there are few research comparisons of print-to-speech and speech-to-print. There is relevant information about that difference, just nothing definitive yet.
Historically, phonics programs tended to emphasize print-to-speech. Kids are taught to identify letters, to link sounds to those letters, and then to sound out words by sounding each letter. That sequence mirrors the process readers must use during reading: look at the letters and use that information to generate a phonological representation.
It seems reasonable to teach students explicitly what we eventually want them to do. However, advantageous curriculum designs do not necessarily mirror their end points so closely. Engaging in a process like reading and learning to read are not the same thing.
Perhaps the opposite – starting with phonemes and pronunciations and connecting those to letters and printed words – might be a good idea. It’s possible that trying to spell and write words does more to enhance phonemic awareness and it may somehow make the phonology more prominent or easy to perceive (Wasowicz, 2021).
The earliest evidence I know of on this was reported by Jeanne Chall (1967). In her qualitative review of research on phonics, she concluded that programs with spelling, writing, and/or dictation did better than those without.
I followed up on that in my reading-writing relationship research in the 1980s. I found spelling and decoding to be closely related, even when a lot of other variables were available to suck up the variance (Shanahan, 1984). Later, Ginger Berninger and her colleagues followed up on that and with an even more ambitious effort they found the same thing (Berninger, Abbott, Abbott, Graham, & Richards, 2002).
Marilyn Adams (1990) and Linnea Ehri (1997) both theorized on that possibility as well, and Steve Graham reported a meta-analysis on spelling instruction that found spelling to improve reading – probably because of its contribution to decoding (Graham & Santangelo, 2014).
That’s all fascinating, but it’s indirect. It suggests value, it doesn’t prove it.
Not everyone agrees with that assessment. Louisa Moats (1998, 2005, 2010), for example, has several publications that treat this as a settled matter, claiming speech-to-print to be most effective. Her reasoning hasn’t convinced me, and yet the preponderance of current data are on her side. (I suspect that adding speech-to-print is effective including adding spelling to traditional phonics instruction, but it is too early to claim it to be a proven fact).
Perhaps the closest thing we have to a direct test of the proposition is a meta-analysis of 11 studies (Weisler & Mathes, 2011). It concluded that instruction that integrated encoding into decoding instruction led to significantly higher reading achievement. Still not the strongest evidence – because it combined investigations that compared encoding with decoding (Christensen & Bowey, 2005) along with those that compared encoding instruction with things like extra math lessons (Graham, Harris, & Chorzempa, 2002).
At some point – any decoding program must focus on print-to-speech, since that is what we do in reading. However, I think there are real benefits to be derived from activities like invented spelling, spelling instruction, word construction from sounds, and so on – in any phonics program. Speech-to-print activities appear to increase learning. My advice: get a phonics program that includes such activities or layer them into a traditional print-to-speech program (including OG).
