Because Trucks are Not Bicycles

October 14, 2020 by Zach Silverzweig

Research Breakdown! Let's take a look at Galletly & Knights fantastic paper and learn how trucks are not bicycles, apples are not oranges, and that not all languages are the same either. This is the first Research Breakdown, taking the the science of reading and make it more accessible to everyone.

This article is a summary and simplification of Orthographic Complexity as an Important Variable in Reading Research by Susan Galletly and Bruce Knight. 

Reading Accuracy is a Precursor to Reading Fluency

In order to read, and understand what we read, we need to take the cryptic marks made on paper and recognize them as the spoken words we use every day. Reading accuracy is the ability to do exactly that, for any given word we come across. Without an ability to read words accurately, higher level skills such as meaning making and critical analysis of a text are hobbled. 

For English readers, a certain level of reading accuracy needs to be achieved by around third grade or it becomes a huge roadblock to progress, both in school and life. And so, in many ways, reading accuracy is a gateway skill. Which makes sense: if you can't read words accurately, how can you hope to read texts fluently?

English is Harder to Read than Other Languages

Language researchers have taken a deep look at all the various languages across the world and found helpful ways to determine the relative complexity of reading a given language. The most important dimension (when it comes to learning to read) is not word length or number of syllables, it's something much more basic.

English is Nastily Opaque

Do the words we write clearly map back to the sounds we speak? If they do, as in Spanish or Italian, we say the language is "transparent." If not, then a language is considered "opaque." Where does English fall on this scale? Off the charts. 

Transparent languages have less than 50 letters and letter combinations to produce their sounds, English has 219 for the consonants and another 342 for the vowels.

Letters in transparent languages typically make one sound, and that sound is typically made only by that one letter. In English, most sounds can be made by multiple different letters (or their combinations) and most letters can make multiple sounds.

Why English is So Confusing for Beginning Readers

Still, the above may seem a bit abstract. So let's get specific here and talk about all the ways in which the English language is incredibly confusing for beginning readers:

  • Many of the common words don't follow any rules and must be taught as complete exceptions
  • The names of letters are not often unhelpful: several consonants don't even include their sounds (CGHQRYW), others don't start with that sound (FLMNSX), and the vowels use their less common long pronunciations as their names
  • Many letters are sometimes silent
  • There are lots of ways to make the same sound: /sh/ as in SHARK, ACTION, MISSION, SOCIAL, CHEF, SURE
  • There are lots of ways to say lots of letters: [o] as in OX, GO, OR, NOW, TOO, BOOK, BOY, COME, WORD
  • For many letters, there are lots of ways to say them and the sounds can also be made by lots of other letters. [a] as CAT, GATE (same sound as EIGHT), ANY (same as END), AISLE (same as ICE, MY), etc. There are 11 more examples like this just for the letter A!

To sum it up, English is considered to be the most complex written language of any with an alphabet. It is so complex, that when these researchers look at language complexity, they remove English because it is off the charts confusing. If you include English in the graph, every other language looks basically the same. It's really, really hard to learn to read.

[English] is not a result of the careful application of this and other principles but a pastiche of different tendencies at different time periods, with chaos a constant companion.

Venezky, 2004

How English Stacks Up Against Other Languages 

So, English is really confusing. Not just as an anecdote, but in the view of language scientists across the world. English complexity means that early readers can't trust what they see to make the sound they expect. This means, quite simply, that it is harder to learn. There is just more a child needs to understand and more they need to keep in their little, growing brains to read effectively. 

And it's hard. In First Grade, an English student has a typical reading accuracy of only 34%. Compare this to, say, well, just about any other language with an alphabet.

Reading Accuracy (%) in First Grade, By Language

British Journal of Psychology. 94. 143-174. 10.1348/000712603321661859.

The stats are incredible: the weakest German readers can read complex, three syllable words better than the strongest English readers can read simple one syllable words; students have higher reading accuracy in Hebrew after first grade than English reading accuracy in grade five, even if English is their native language. 

The science clearly demonstrates that the difference in the table above is not related to age or socio-economic factors, it is a simple function of the complexity of the language. 

What's the Impact of a Difficult, "Opaque", Complex Language?

English being an opaque language makes a huge difference in the learning process. Let's compare it with transparent languages:

  • Students of transparent languages typically achieve reading accuracy and phonemic awareness in one year of study
  • Fewer students of these languages experience delays in reading accuracy, and most of those that do can be corrected with a little training
  • Students with severe mental disabilities can still learn to master reading accuracy and spelling in transparent languages
  • In transparent languages, weaknesses in early reading skills (RAN, Phonemic Awareness) don't translate into roadblocks to reading

Additionally, the impact of this complexity falls heaviest to the lowest performing students. The following graph shows the gap between reading skills in a transparent language, Welsh, compared to English:

english is harder for lower literacy levelsAs you can see, the bottom quarter of kids learning to read English can barely perform, while the bottom quarter of Welsh kids average almost as high scores as the second quartile of English readers.

These serious challenges in the language itself then cascade into a whole host of additional problems faced by educators when dealing with a complex language.

In contrast, teaching a transparent language allows for:

  • Simpler, uncontroversial early reading curricula (no Whole Language vs Phonics, a.k.a. "Reading Wars")
  • Instruction takes significantly less time
  • Teacher training takes significantly less time
  • Virtually all children can read and write within two years of school, allowing for continued progress to higher level skills
  • Classes are more consistent, with every child reading, so the teacher can focus on more grade-level appropriate learning

The Wrap Up

We hope you enjoyed this tear down of the work of Galletly and Knight. We covered about a third of this fantastic paper. If these topics interest you, definitely check out the original work here

Hopefully the main point comes across loud and clear: English is extremely difficult to master because of the way we write it. Most languages can be learned in a tiny fraction of the time it takes to learn English. 

We think there might be a better way to go about solving our literacy crisis: go after the root cause and fix the language itself. It's a big idea, rooted on the shoulders of the research that came before us.

We'll be back soon with another Research Breakdown! Until then, ciao!
