The Science of Reading and Chesterton's Fence

 Image source

It’s January 2021 and as I’m sure you've noticed, the world’s best and brightest microbiologists, virologists and immunologists are working around the clock to throw everything that science has at a microbe that at the time of writing has caused 1.98 million deaths, wreaked havoc in people’s lives and damaged global economies. This is not a blogpost about COVID (collective sigh of relief) but it is a blogpost about science, and how we humans have a peculiar tendency to work against our own best interests in some aspects of improving life on earth. 

One of the ways in which we make life hard for ourselves is by destroying things because we don’t understand their value or original purpose. In 1929, English writer, philosopher and polymath Gilbert Keith Chesterton* (1874-1936) wrote a book called The Thing, in which he stated (emphasis mine):  

In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it. 

Now I know many readers of this blog will be familiar with the history of reading instruction and will see parallels here in how reading “reform” occurred during the twentieth century. Whole Language advocates (later followed by their balanced literacy descendants) wandered into the field (literally and metaphorically) and saw some fences and gates, such as explicit teaching of how speech and print map to each other, could not see their point, and so ordered their removal. And removed they were. This is a classic example of what Chesterton described as “first order thinking”, as noted by the team at Farnam Street. Resonance with the history of reading instruction will become even stronger as you read on (emphasis is mine):  

When we seek to intervene in any system created by someone, it’s not enough to view their decisions and choices simply as the consequences of first-order thinking because we can inadvertently create serious problems. Before changing anything, we should wonder whether they were using second-order thinking. Their reasons for making certain choices might be more complex than they seem at first. It’s best to assume they knew things we don’t or had experience we can’t fathom, so we don’t go for quick fixes and end up making things worse. Second-order thinking is the practice of not just considering the consequences of our decisions but also the consequences of those consequences. 

Everyone can manage first-order thinking, which is just considering the immediate anticipated result of an action. It’s simple and quick, usually requiring little effort. By comparison, second-order thinking is more complex and time-consuming. The fact that it is difficult and unusual is what makes the ability to do it such a powerful advantage. Second-order thinking will get you extraordinary results, and so will learning to recognize when other people are using second-order thinking

First order thinking in reading instruction yielded the apparent simplicity of a field without what seemed like an unnecessary fence in the middle of it. Decades later, we can see the forethought of those who put the fence there, as well as the downstream havoc created by its impulsive and reactive removal. Examples of this havoc are a current teaching workforce who were themselves subjects of the Whole Language experiment and were not taught to spell, were not taught the rules of grammar and lack an explicit understanding of how spoken and written language work. Sure, some have picked these things up along the way, but hit-and-miss is hardly a strategy for teaching children, let alone preparing a workforce and guarding against the loss of cultural capital that is encoded in spoken and written language.

Since the 1980s, many teachers, academics, clinicians and policy makers have struggled valiantly to explain to decision-makers why this first-order thinking was so gravely flawed. There’s been three national inquiries (the USA in 2000, Australia in 2005 and the UK in 2006) all one way or another stating that the fence should not have been removed and recommending its reinstatement. 

There’s been the ongoing march of reading science, affirming the need for this fence if all children, not merely a fortunate subgroup are to learn to read. There’s been ground-up action by parents, despairing of the distress and shame experienced by their struggling offspring. 

And still in 2021, we see first-order thinking manifesting itself in statements such as “there is no science of reading**”. Back to Farnam Street (emphasis mine):  

Chesterton went on to explain why this principle holds true, writing that fences don’t grow out of the ground, nor do people build them in their sleep or during a fit of madness. He explained that fences are built by people who carefully planned them out and “had some reason for thinking [the fence] would be a good thing for somebody.” Until we establish that reason, we have no business taking an ax to it. The reason might not be a good or relevant one; we just need to be aware of what the reason is. Otherwise, we may end up with unintended consequences: second- and third-order effects we don’t want, spreading like ripples on a pond and causing damage for years. 

So – why do we continue to be plagued by first-order thinking in reading instruction? It’s not uncommon to hear claims such as “there is no science of reading”, “every child learns differently”, and “teachers should be trusted to use a range of approaches”. Reading instruction has been the subject of close human inquiry for decades (at least), and over time, brick-by-brick, we’ve amassed a body of knowledge about what reading is, how best to teach it so that all children, not just a lucky subset succeed, and how to identify and support those who struggle. 

Is this knowledge base complete, perfect and settled? No, of course not. 

Do we know enough to be able to recommend system-wide practices that should be adopted or ceased? Yes. 

Do we systematically work from the same songbook on this? No. 

Like Chesterton’s Fence, this knowledge was not created by accident or on a whim. No one built it in their sleep. Rather this particular fence was built slowly and carefully, and like all scientific endeavours, with imperfections and the need for repair and revision along the way.  

If, however, in 2021, you claim “there is no science of reading” you are saying you don’t understand the need for the fence that was built by our predecessors and you will be prone to do wilful damage to it, or at best, to neglect its maintenance. 

 If you assert that “there is no science of reading”, then these are the kinds of first-order Chesterton’s Fence thinking errors you are making: 

1. Decades of generally rigorous research conducted by knowledgeable, well-motivated and disciplined cognitive scientists, educational psychologists, neuroscientists and so on tells us nothing about what reading is as a human skill. 

2. Because you don’t understand the science, it can be neglected or torn down. 

3. Because you don’t understand the reading fence, you can also dismiss related bodies of knowledge in human cognition, perception, learning, language and memory. 

4. We’ve learnt nothing in the last 50-plus years that can be usefully applied by teachers and so should be consistently taught to pre-service teachers when they are at university. 

5. Teaching is really just a craft, not guided by a body of scientific knowledge (metaphorical fences), but in spite of this, teachers should be afforded high professional standing in the community.

 6. We know nothing about how to identify and support struggling readers. 

7. Some children can’t be taught / were not read to enough as infants / don’t have enough books at home / don’t want to learn / will get there when they are ready. 

8. All children learn differently. 

9. Becoming a reader is no different from developing oral language and we will poison children against reading if we use formal instruction. 

10. The orthography of English is too complex for formal instruction so children should be encouraged to memorise “sight words” and guess unfamiliar words using picture and context cues. 

11. Systematic synthetic phonics instruction excludes vocabulary and other aspects of language development 

12. Phonics can only be taught properly using a commercial program, or alternatively, advocacy for phonics instruction is purely motivated by commercial forces. (Have you looked at the business models behind levelled texts lately?

13. As long as phonics is “in the mix”, children will learn to decode. 

History will be the judge of how we cooperate on the re-construction of a fence whose purpose was poorly understood by some of our predecessors, but there is no excuse, in 2021, for continuing to neglect or damage the science of reading fence, no matter how imperfect it may be. Children’s lives literally depend on being given every opportunity to become readers without the hindrance of depression and anxiety, low self-worth, behavioural comorbidities, suspensions and expulsions, and trying to access sparse, generally inadequate intervention services.  

The fence was put there to protect children but was impulsively demolished by adults who were not using second-order thinking. The grown-ups need to re-instate it and care for it properly.

GUEST BLOG: But what if there was a screening test for COVID-19?

This Guest Blog was written by Associate Professor Tanya Serry*, Co-Director of the newly-established Science of Language and Reading (SOLAR) Lab in the School of Education at La Trobe University, Australia.

While COVID-19 plays havoc with our minds, our health care workers and our economy, let’s just imagine that a COVID-19 Screening Check was available from tomorrow. We’ll call it CSC for short. In the spirit of any screening check (think breast screening, hearing screening, antenatal ultrasound screening), the CSC acts as a population-based preventative measure for early detection of the virus. While your imagination is running wild about the CSC, let’s also assume that those identified as positive on the CSC, will be eligible for early, evidence-based medical care. Let’s also assume that for most people, (say about 80%), the treatment is short, sharp and effective; well before the virus causes fever, fatigue and fear. What a huge relief and wonderful safety net that would be. What a cause for celebration.

But what if we substituted CSC for PSC: the Phonics Screening Check? Would there be as much fanfare? Unfortunately, the answer is no, even though the PSC performs a similar function as our imagined CSC, but in relation to identifying students who are not tracking as expected in learning how to decode. It’s just that reading difficulties are a slow-burn virus that can take a lot longer to declare themselves, unlike COVID-19, which has a short incubation period. More about that later.

Background to the Phonics Screening Check

The Phonics Screening Check commenced in the UK in 2012. According to the South Australian Department for Education, which had the foresight in 2018 to trial the check statewide across publicly funded schools, the check is ‘… a short, simple assessment that helps teachers to measure how well students are learning to decode and blend letters into sounds - one of the building blocks for reading.

The Check (note the word check and not test) is conducted towards the latter half of Year 1 to monitor students’ progress in learning to decode words and in particular, to achieve the early identification of children struggling with decoding. The PSC takes between four and seven minutes to administer and consists of 40 items: 20 real words and 20 pseudowords. Herein lies the rub: pseudowords; loved by some, despised by others, misunderstood by many.

Real words could be for example: ITS, SUM or THIRD while pseudowords could be OSK, PAB or DARP. You’ll see that the pseudowords are all phonologically legal and phonotactically identical (respectively). I can’t show you a picture of test items as they are not labeled for reuse. However, the reality is that every word that children encounter, real or pseudo, is new for a novice reader at least once. All the PSC is doing is determining whether Year 1 students can decode phonologically legal combinations. Perhaps in an ideal world, where there was overarching support for the concept of a PSC, the entire check could be pseudowords. That would really be the purest way of tracking students’ decoding abilities; but for now, a bridge too far. It would mean however that we would not see ill-informed comments reported in newspapers such as Apparently, puzzling over the sounds of "flisp" is going to help children learn to read and write.

So how does the Phonics Screening Check stack up against the CSC?

If we reflect on the likely support for the imagined CSC and the real-life PSC, it would go something like this:

Properties of the check

 (Imagined) CSC

(Real) PSC

Provides early detection of risk?

Yes: for COVID—19.

Yes: for ongoing difficulties learning how to decode words.

May identify some false positives?

Yes: but better safe than sorry.

Yes: but better safe than sorry.

May identify some false negatives?

Yes; it’s a possibility but managed by close progress monitoring of COVID-19 ‘symptoms’.

Yes; it’s a possibility, but managed by close progress monitoring of ‘signs’ of reading struggles.

Offers intervention options?

Yes: evidence-based treatment to significantly reduce the virus taking hold.

Yes: evidence-based treatment to boost the word decoding abilities of children .

Effective for everyone?

About 80% will benefit from the treatment. The remaining 20% are likely to need more intensive treatment.

About 90-95% will benefit from a brief but intensive Tier-2 reading intervention. The remaining 5-10% of students will need more intensive, more enduring Tier-3 treatment.

Reasons not to use it?

None identified.

None identified although there is much misinformation about its use.

 The good news

On August 2nd, a media release was circulated by the Hon Dan Tehan MP (Federal Minister for Education) headed 2020, Free phonics check for all Year 1 students. In this release, the Minister was quoted as saying “Importantly, Phonics Check results provide teachers with a useful picture of where individual students are at in their reading, so they can implement the right support for those who are struggling…”

How good is that?

Well yes, it’s good if you support the Phonics Check (like I do). And if you do support the Phonics Check, implicitly that means that you understand:

  • That the ultimate aim of reading is to gain meaning;
  • That Gough and Tunmer's (1986) Simple View of Reading (which states that reading is a product of being able to decode words and understand spoken language), is theoretically sound;
  • That novice readers (5-6 year old students) need to be taught how to “crack the code” of English.
  • That learning to decode accurately and efficiently is the first, crucial step to becoming a competent reader;
  • That not all children will learn to “crack the code” without explicit teaching, but these children do not necessarily have a learning difficulty;
  • That structured literacy using a synthetic phonics approach is the safest way to ensure that children learn to decode words;
  • That a systematic scope and sequence is superior (safer and more trustworthy) to a non-systematic approach (see here and here; and
  • That humans were not born “wired to read (and spell) and therefore need to be taught, ideally in a systematic and explicit way.

Why the backlash?

Those who challenge the value of the PSC use the straw-man argument that says “decoding alone does not a good reader make”. But that’s just not correct as shown by the evidence (see for example here and here). Take the Simple View of Reading which states, in the most elegant way, that being a competent reader comes about by being able to (i) decode well and (ii) have a solid grasp of oral language comprehension. Then there is the very important work of Professor David Kilpatrick who has demystified for us all, that critical step of moving from decoding in a rather mechanistic; sound-it-out way to developing orthographic mapping skills for fluent effortless word reading (the 70min investment in the hyperlinked YouTube video above is well worth it).   

The sound-it-out decoding part, which is all the PSC is used for, opens the door to becoming a competent reader. That’s all. In the same way that we would be fist-punching for that imagined CSC, universal acceptance of the PSC, which is at our fingertips and on our iPads, should elicit the same joy. The joy of reading, in fact
