The Speech Language Pathologist-Teacher Tango


Image source: http://www.freedigitalphotos.net/ 

Because of my interest in the language-literacy nexus and school success, I was very interested to read the following in a recent post on the Speech Language Literacy Lab blog: 

Service delivery models have changed substantially over the last few years. While small pull-out groups are appropriate in many situations, keeping students in their classrooms is more of a priority than it has been in the past. As SLPs, we are often told by administrators that we should be "pushing-in" to general education, and providing services in the classroom. 

This post called to mind some thought-provoking conversations I had with various UK colleagues during my recent visit there. Professor Courtenay Norbury (Royal Holloway, London) was lamenting the fact that Speech Language Therapists in the UK are increasingly providing a secondary consultation service to teachers and classrooms, spending very little time working 1:1 with those children whose poor language skills pose serious and imminent threats to school success, both academically and socially. Courtenay and I discussed the fact that classrooms are educational, not therapeutic environments, and teachers (or indeed teaching assistants) cannot be expected to provide the kinds of specialised, individually-tailored intervention that children with significant language difficulties need, in order for them to engage with the curriculum and form social connections with peers. If SLTs (SLPs in Australia and the USA) are operating more at Tier 1 in a Response to Intervention (RTI) framework, with occasional Tier 2 work and virtually no Tier 3 interventions, this has serious implications for (a) the extent to which such children have their educational trajectories altered, and (b) the development and maintenance of professional SLP skills in ameliorating complex expressive and receptive language disorders in young children. Courtenay observed that a consultation-only model is a sure-fire route to redundancy of the specialist knowledge and skills that sit within the SLP profession.

Some commentators have referred to SLPs providing their 1:1 services to children in "homeopathic doses" -  a charge that most clinicians would recoil from, yet it is hard to argue the other corner if a sufficient intervention frequency and intensity cannot be demonstrated. It will also be difficult to establish the efficacy of SLP interventions if they are conducted in ways that promote classic Type II errors, if not statistically, then certainly in the minds of administrators and policy makers. Remember the dinosaurs?

The other conversation that stands out for me in relation to SLPs and teachers working together on the issue of early literacy instruction is the one I had with Professor Bill Wells at the University of Sheffield. When I commented during a presentation that teachers have, in recent years, received uneven pre-service preparation on the linguistic basis of the transition to literacy, Bill rightly asked me whether I thought SLPs learn enough about how reading should be taught during their pre-service education. While I can't call on any empirical data to answer this question, my guess is that an audit of SLP curricula would reveal similar gaps and unevenness to that which has been reported in teaching curricula concerning linguistic precursors to reading.

So - if we are wanting SLPs and teachers to meet in the middle, then it really will take two to tango.

Dancing Tango

Faculties of Education need to ramp up their curricula with respect to linguistic precursors to literacy (vocab., phonemic awareness, narratives, syntactic complexity and so on) and Speech Language Pathology curricula are going to need to cover historical, epistemological, and pedagogical approaches to reading instruction. If this isn't done, too much time will be lost in trying to deal with turf issues and find a common language between professions. If it is done, however, the children who really need them might have better chances of receiving those Tier 2 and 3 services that genuinely impact on their language, academic, and social struggles.

I am absolutely all for SLPs and teachers working collaboratively at Tier 1, sharing knowledge, both of theory and of individual children. At Tiers 2 and 3, however, SLPs need to be able to offer targetted services to children whose language needs will never be met in the context of the mainstream classroom. Advocacy for this needs to come both from the education sector and from SLP/SLT peak bodies. Failure to do so will "dumb down" the skill-base of the SLP profession and will entrench developmental disadvantage for those children whose language skills are not adequate to meet the rapidly changing academic and social demands of the classroom.

Re-visiting the Language House

In a blog-post back in December last year I shared an image of a "Language House"  that I often use in professional development sessions with teachers.

As a result of a recent very enjoyable after-dinner discussion with Sally, a Speech-Language Pathologist  in Madison, Wisconsin, I've slightly modified this, to take in the importance of such "houses" being built on solid ground - in this case, the social contexts and purposes for language use in the real world.

I have pasted the updated image below - I think it will make our house both more solid and better able to resist a metaphorical force-10 gale, whether academically or socially.

Language skills and the social gradient



I have recently returned from a very busy 5-week overseas trip as part of my sabbatical leave this semester. This trip enabled me to visit a small handful of researchers and academic departments whose interests intersect with mine with respect to language development/disorders, early literacy instruction, and psychosocial aspects of being an adolescent with a language-learning disability. I spent most of my time in the UK, but also had some time in the USA, the latter predominantly dealing with issues pertaining to language competence of young people in the youth justice system.

My trip provided some wonderful opportunities to reflect on contemporary issues and challenges pertaining to the language-learning impairment field, and to consider ways in which current research agendas in various centres are tackling different aspects of some of the “big questions” of our time.

For me, one of the most compelling issues for researchers, policy makers, and practitioners is the social gradient that exists with respect to early language exposure, and to language skills and academic success during the school years (and no doubt beyond, but data is lacking on this).


Many readers of this blog would be familiar with the work of Hart and Risley in the USA in the mid 1990s. In a nutshell, these workers recruited 42 families who were stratified across three layers of socio-economic status (SES) spectrum – parents from professional backgrounds, those from working class backgrounds, and those who were recipients of state welfare. At the outset of the study, these families had an infant who was 9 months old, and over a period of 36 months, Hart and Risley tape-recorded an hour per month of child-directed parental language. Their quantitative findings are summarised in the figure below, however it is must be noted that there were important qualitative differences across the SES spectrum too. Most notably, children of professional parents tended to experience parental language that was more encouraging, and they also received more expansions and elaborations on their utterances.



Although Hart and Risley’s work in this area is probably the most well-known, it’s important to note that similar findings have been reported by other workers as well, e.g. Hoff (2003), Locke et al. (2002), Spencer et al. (2012), and Weisleder and Fernald (2013). Also, it must be remembered that of course some families who are struggling economically never-the-less have the human and social capital to provide linguistically enriching environments for their children. Conversely, some high-income families struggle in this regard. So SES correlates with, rather than determines the nature of the verbal input that children receive. Studies such as these are not about "parent-blame", irrespective of the fact that the tabloid media will mis-use them in that way from time-to-time. Rather, this line of inquiry is simply about being data-driven and then considering applications of the data - as should be the case in all social sciences research 

In our work on young offenders, we have reported high rates of language impairment on formal testing, and of course young offenders as a group overwhelmingly come from low SES backgrounds. However we have also examined the language skills of non-offending controls from similar SES backgrounds and have found that in spite of being an average of two years younger, the controls out-performed their offending peers across the board on language measures.

So – low SES alone does not account for poor language skills in vulnerable young people; nor, incidentally, are such differences accounted for on the basis of nonverbal IQ. Other factors, such as chaotic family structure, disrupted education, and developmental comorbidities such as behavioural difficulties all need to be considered.

Perhaps language is not quite as robust to the effects of environmental disruption / deprivation as we might previously have believed. 

What is inescapable, however, is the fact that there is a social gradient with respect to early language exposure and at least mid-range language outcomes such as academic achievement. Schools, teachers, clinicians and policy makers all know that some schools cater to communities that are economically and socially disadvantaged and this disadvantage manifests as lower achievement overall on tasks that require strong verbal skills. And it’s hard to think of many aspects of an academic curriculum that don’t require strong verbal skills.   

However inescapable such a conclusion may be though, it raises many more questions than it answers, for example:

        What is the basis of this gradient? Exactly what is it about being poor, and/or less well educated, that reduces the quantity and quality of language experiences made available to young children? Is this purely a social-environmental phenomenon that can be “rectified” by changing the behaviour of key adults in a child’s immediate networks?

     Is it possible that what looks like a social phenomenon actually reflects an underlying, genetically transmitted disadvantage with respect to oral language skills? I am no expert on genetics (far from it!), but of course we must recognise that many human characteristics are genetically influenced, if not determined – e.g. height, body morphology, eye colour, skin tones, and so on. There is an established link between genetic factors and  language skills.  Is this link enough, however to account for a stratification of society with respect to capacities for acquiring and using language?

        If the social gradient is biologically determined, is there any point trying to intervene to improve the life-chances of children with “deficient” language skills? A nihilistic view of the world would suggest that such interventions are unlikely to be beneficial and/or economically justified. The evidence on interventions such as Head Start (the USA) and Sure Start (the UK) is not exactly bursting with reasons for excitement over the benefits of targeting “at-risk” communities and providing a verbal “top-up” prior to school entry.

        If a child comes from an economically disadvantaged community/family/school and has oral language skills that place him/her in a clinical range on standardised language measures, do we simply attribute the language profile to social circumstances? Can such a child also have what would, under other circumstances be referred to as a “specific language impairment” (SLI)? If the answer to the last question is “yes”, how do we determine which poor children have “language impairments”, Vs having language skills that are commensurate with their position on the social gradient, albeit woefully inadequate when it comes to academic and social success at school?

These are all big questions facing child language researchers, policy makers, and practitioners in speech-language pathology as well as education. These questions are also central to the current terminology debate concerning children with language difficulties.

My view is that while it is important for researchers to vigorously investigate and classify the various aetiological pathways that lead to compromised language skills, we cannot forsake the academic and social outcomes of large numbers of children simply because we know they are “poor”.  In fact, evidence would suggest that such children may derive particular benefits from rigourous application of evidence in the early years’ classroom. For example, a pilot investigation we recently conducted in Victoria suggests that targeting teacher knowledge and practice with respect to early oral language and literacy development has a direct and beneficial effect on the performance of children in disadvantaged schools. A larger scale investigation is now attempting to replicate this finding, and I hope I can report positive outcomes via this blog in due course.

If learning to read is a “linguistic task”, what’s wrong with Whole Language?

Although it is some years since I have worked clinically, my initial qualification was in Speech Language Pathology and I have always had a particular interest in, and passion for language – both spoken and written. I love spending time with infants and toddlers and observing their amazing emergent grasp of the linguistic code – surely one of the greatest wonders of being human. My research activities in recent years have had a strong focus on “vulnerable” learners and I’ve had the enormous privilege of spending a lot of time in primary schools, interacting with teachers about (in particular) the teaching of reading in the early years.

A large focus of the presentations I give to teachers is explaining the linguistic basis of learning to read. This entails discussion of the fact that unlike learning to talk and understand, learning to read and write is biologically “unnatural” – i.e. humans are pre-programmed in an evolutionary sense for the former, but not the latter. This concept is often quite a revelation for teachers and I see many “ah hah!” moments in the course of these discussions.
I often use an analogy of a child having to “cross a bridge” in the early years of school – from talking and listening on one side, to reading and writing on the other. If I’m feeling particularly prosaic on a given day, I might mention the crocodile-infested waters underneath….

While some fortunate children will metaphorically “skip” across the bridge and suddenly find themselves on the other side without having had much awareness that they were even on a bridge, many will find the experience one that requires conscious focus, guidance and support from adults, and carefully-paced milestones. Complex genetic and social factors no doubt account for such variability, but classrooms need to cater to all children, not just the very able.
Proponents of Whole Language-based approaches to the teaching of reading argue that reading is as natural as talking, and so simply requires immersion in text-rich experiences, in order for children to find themselves on the far side of the bridge.

This argument fails a number of reality checks however, the first of which is that children’s acquisition of oral language, while strongly “pre-programmed” in an evolutionary sense, still requires enormous environmental input and interaction, in the form of exposure, simplification, repetition, imitation, expansions, recasts, and so on. There is something of a “dose-response” relationship between early language exposure and verbal skills in early childhood, such that this is a phenomenon that sits on a social gradient (see references below).  
Secondly, decades of cognitive psychology research tells us that the acquisition of skilled reading draws heavily on the child’s psycholinguistic knowledge about how their language works. Now of course we can’t sit down and interview a four-year old about her psycholinguistic knowledge, but we can extrapolate important information from spontaneous language samples and from the 1:1 administration of formal language measures.
By “psycholinguistic knowledge”, we are referring to the child’s grasp of grammatical rules (e.g. in English, the fact that in order to make a noun plural, we generally add an “s”), knowledge of narrative structure (the logical and sequential way in which experiences are organised and presented for the benefit of a listener), vocabulary use and comprehension, and knowledge of grammatical conventions to link words and express increasingly complex (e.g. embedded) ideas. Knowledge of the sound system (phonology / phonemic awareness) is critical, as it is the means by which a child can segment and blend sounds to manipulate and integrate word components. Finally, knowledge of pragmatics teaches the child the subtle and sometimes confusing social conventions around how language is used in a variety of communicative contexts.  We typically learn many of these rules through the process of breaking them, and then receiving some kind of corrective input from a nearby adult, such as a parent or teacher.

Bear in mind too that all of these psycholinguistic milestones need to be mastered in both the receptive (comprehension) and expressive (spoken) modalities. Further, children need to master the understanding and use of literal language as well as figurative, or idiomatic language. Everyday communication would be quite boring if we only ever said exactly what we mean. Instead, we make our exchanges more interesting and entertaining (but often more confusing!) by using linguistic devices such as metaphor, sarcasm, and humour.
As children's grasp of oral language develops, they acquire the ability to think and talk about language and how it works, i.e., metalinguisitic abilities, and these can then be drawn on in the early years classroom and in everyday life, e.g. to explain why a joke is funny. 

Oral language, then, is one of those deceptively complex processes that by virtue of its pervasive presence in our lives can appear simple, or even inconsequential, as a developmental achievement.  
It is neither.
So when educators argue the virtues of Whole Language as a reading instruction approach, they are conveniently lumping together a raft of linguistic microskills that the child is (a) still acquiring and refining and (b) needs to draw on in order to cross the bridge from talking and listening on this side, to reading and writing on the other. To the untrained eye, however these skills are not observable or accessible.
The fact that “Whole Language” has the word “language” in its name is both unfortunate and misleading, because learning to read IS a linguistic task, but Whole Language does not deliver, unpack, decipher and value-add the linguistic goods that all children need to acquire in order to learn to read. The fact that some (fortunate) children will learn to read in Whole Language classrooms simply attests to the enormous variability that teachers in early years settings need to address.
My driving motivation is to provide all children with access to the life-changing opportunities that await their arrival on the other side of the bridge. I'm sure this is the driving motivation of all who are invested in early years education, however examination of the research evidence shows uneven results.
That Whole Language is an approach that fosters passion about children's literature is laudable. However, direct instruction by teachers who understand the psycholinguistic properties of the language of instruction is key to shepherding more children to the other side of the reading bridge, safe from those crocodile-jaws of early academic failure.

Reading Recovery and Cassandra's Curse




Last week, I attended an excellent, though quite depressing seminar organised by Learning Disabilities Australia, entitled Reading Recovery and the Failure of the New Zealand National Literacy Strategy, presented by Professors Bill Tunmer and James Chapman (both of Massey University). A summary of the content of the presentation can be found in this paper.

The seminar was very well attended, with senior policy folk from the state and Catholic sectors present, as well as a number of education and speech pathology academics and practitioners, teachers, tutors, and other interested parties. The questions and comments from the floor were many and I think people would have stayed on for hours continuing the discussion if that had been possible. 

So why did I find it depressing? The first depressing aspect was the 
established evidence on Reading Recovery's failure to deliver (as per PIRLS data) on the stated aims of its developer, the late Dame Marie Clay (1993), to 

".....help children acquire efficient patterns of learning to enable them to work at the average level of their classmates and to continue to progress satisfactorily in their own school's instructional program. When recognized training accompanies the use of procedures contained in this book, success rates are consistently high and surprising."

The second depressing aspect was the fact that policy makers (and as a consequence many, though by no means all, teachers) have been slow to acknowledge and act on the irrefutable data that Reading Recovery is not delivering on its promises. That it is in particular, leaving behind children who come from low socio-economic status families and schools is especially disappointing and unforgivable. 

No-one would disagree with the importance of helping struggling learners to catch-up, and the earlier the better. That's where the consensus in this debate ends, however, and the so-called "reading wars" saga rears its ugly head. I don't intend to deconstruct this debate here (plenty of metaphorical ink has already been spilled on that one), but it is important to note that Reading Recovery is a "child" of the Whole Language movement. In essence, this approach to teaching reading, espoused in the late 1960s and 1970s by Kenneth Goodman stemmed from the attractive (though unsubstantiated) claim that children can acquire literacy skills in much the same way that they acquire oral language skills - through experiential immersion. While this idea may have had strong face validity and appeal to the educational zeitgeist, it lacked one critical ingredient - an empirically derived theoretical basis. In fact, we now know (and probably knew back then) that unlike learning to speak and understand, learning to read and write are biologically "unnatural" acts (Gough & Hillinger, 1980) requiring sustained specific instruction. As Melbourne Speech Pathologist Alison Clarke explains in 
this engaging YouTube clip phonics-based reading instruction was suddenly deemed "old fashioned" and was pretty much universally abandoned in Australian schools (and teacher-training courses) in the 1970s, in favour of Whole Language-based approaches. 

Many aspects of Reading Recovery have long perplexed me, most notably the question of what is being "recovered" for children who had not acquired the requisite skills in the first place? Secondly, I don't understand why any education system would adopt a reading instruction approach (Whole Language) that assumes a 15-20% failure rate (and need for expensive and intensive intervention) by the end of the first year of school ("failure" here referring to the lowest performing students in the class - those whom Clay argued could be brought up to the norm via Reading Recovery). Why not simply employ effective, evidence-based teaching approaches for all, and move the whole curve to the right?


Imagine a hospital administrator deciding that operating theatre infection control guidelines were "old-fashioned" and unwieldy, and so proclaiming that henceforth, we'll dispense with strict hand-washing protocols, letting practitioners use their own judgement on this, and rely instead on people's natural immunity. As a fall-back, anyway, we have postoperative antibiotics for the tail of the surgical curve who (inevitably) happen to develop a serious infection. Of course those in that tail will already be disadvantaged in other ways, e.g., being older, or having multiple comorbidities, making their immune systems compromised and their benefit from antibiotics equivocal at best, and non-existent at worst. Let's not even try to calculate the cost to the system (and society) of increased length of stay and lost social and economic productivity. 


Of course such a situation would not occur and most would read that scenario and consider it laughable. But why are health and education so different with respect to the way in which evidence is derived, critiqued, and applied?

One key factor might be that when hospitals adopt systems that don't work, patients die, and people can see that patients die. When schools adopt systems that don't work, no-one dies and practitioners are largely shielded from the detrimental effects of their practices, however pernicious these effects may be over the longer term.

However just as we can't hold individual doctors accountable for policies enacted in hospitals, we can't hold individual teachers to account for policies enacted by their schools or education sectors. We must, however, hold policy makers and those who are responsible for teacher training to account to apply evidence ethically. The Whole Language-Reading Recovery grip on teacher education and early years practice is doing a huge disservice to the most vulnerable and socially disadvantaged learners. These are the very learners who need school to 
accelerate their progress relative to more advantaged peers. The evidence presented by Tunmer and Chapman shows unequivocally that such acceleration is not occurring in NZ, and there is no evidence (of which I am aware) to indicate that it occurs here either. 

I teach medical students enrolled in an undergraduate MBBS. Putting aside for a moment differences in university entrance requirements for medicine Vs teaching, a major difference I see between these students and those in education (whom I have also taught) is their capacity and willingness to question and challenge evidence that is presented to them. In medicine, we know we would be producing graduates who are frankly dangerous to the community if they do not exit university as astute life-long consumers of new research and of edicts from "on high" (e.g. hospital administrators) that they should adopt or abandon a particular practice. Student doctors are taught to "argue their corner" and to do so using the language of evidence, not anecdote. Treating a medical condition is a matter of science (blended with positive personal qualities such as warmth and respect), not a matter of personal ideology (with a few notable exceptions, such as termination of pregnancy, where guidelines exist for how doctors should deal with their personal biases so as not to disadvantage their patient).

In the case of reading instruction however, we seem to have a terrain that has elements of religious boundary-setting around what teachers (and their educators) can and cannot be challenged over. This is ethically indefensible and if allowed to continue will simply perpetuate the widening gap between the "haves" and "have nots" in the early years classroom and beyond. There is nothing progressive, socially or educationally, about standing by and being complicit in maintaining such an unfair status quo.


Academics who have interrogated the evidence on Reading Recovery and found it to be wanting seem to have been afflicted by Cassandra's Curse - the ability to predict the future alongside the sure knowledge that they will be ignored.
