Dyslexia is a specific learning difficulty that among other things, can impact on an individual’s ability to break words down into their component phonemes, a crucial skill involved in reading, writing and spelling. People with dyslexia may be highly intelligent and creative individuals but still struggle with basic literacy skills.
With the right help, these challenges can be overcome, but because no two dyslexic students present the same set of symptoms, it is sometimes difficult for educators to identify the most effective teaching solutions.
That’s one of the reasons why researchers have attempted to group commonly observed forms into different categories, to make finding treatment easier and ensure dyslexic children of all types don’t fall behind their peers.
However, knowing how to identify dyslexia early on is just as important as being familiar with the different types. A child with dyslexia may be quite bright, but his written work will often not reflect the extent of his vocabulary.
He may present symptoms such as reversed numbers and letters, find it hard to remember the spelling of common words, especially sight words, and can struggle with reading, copying work and following instructions. He may also be disruptive in class and in some instances even adopt an anti-academic attitude as a way of dealing with the feelings of frustration and low self-confidence that result when children with learning difficulties are labelled as lazy, slow or even “not good” at reading.
But there are ways teachers and parents can help dyslexic children achieve confidence in an academic environment. One of the most effective approaches is via a touch-typing course that provides opportunities to overlearn the spelling of common vocabulary and other words that reinforce sound-letter correspondence.
Taking a multi-sensory approach also makes it easier for written assignments to be completed on a computer, which is helpful for dyslexic children who also struggle with dyspraxia. More importantly, when a child can learn at a pace that’s just right for them, they feel more in control of their learning and build positive associations with reading, which are then carried over into the classroom.
Even adults with dyslexia can benefit from a typing and spelling course, and it’s never too late to learn. One TTRS user didn’t become a reader until after he retired from work! For more information, get in touch with the TTRS team or sign up for a free trial.
6 Types of dyslexia
Depending on the theory, you will find different types of dyslexia discussed. It’s important to note that there are no official subtypes of dyslexia and different schools of thought have taken different approaches to dividing them up. Additionally, a learning difficulty can vary greatly from individual to individual and people may show symptoms from multiple types or be of the same type and have different symptoms.
Did you know that 75% of people who have dyslexia experience difficulty in breaking speech into individual sounds? Every language has a set of commons sounds that it reuses over and over again to form words. People with dyslexia have no trouble producing and processing the sounds they need to speak their native language. The difficulty comes with identifying the individual sounds that make up a word.
It may not seem like sounds are important in reading, but one of the first steps children must take in learning how to read is decoding words. This involves sounding them out one letter or group of letters at a time, which is a particularly challenging activity in English as there are various ways of spelling the same sounds.
To illustrate the point, here’s a tongue in cheek alternative spelling of “fish” from the pen of George Bernard Shaw: Take the f sound from tough, the i sound from women, and the sh sound from nation, and there you have it - the way to spell fish is “ghoti.” If you struggle to hear the sequence of sounds that come together to form a word, you won’t necessarily know a word when you see it or be able to spell it when it comes time to write it down.
Some individuals also experience Surface Dyslexia, which can cause them to take longer to process language when they move beyond the decoding stage. Not all words are spelled as they sound in English and sometimes we meet a word that gives us no clues as to how it is pronounced.
This can happen to all native speakers in English, which is why we memorize irregular spelling so a word can be recognized when it is next encountered. But children with Surface Dyslexia have trouble seeing the whole word. This causes comprehension difficulties and greatly increases processing time required for reading.
Symptoms often include trouble reading and remembering what has been seen on a page. That’s because of all types of dyslexia, Visual Dyslexia impacts on visual processing, meaning the brain doesn’t receive the full picture of what the eyes are seeing. This can have severe implications for learning to form letters and also mastering spelling, a process in which remembering the correct letter sequences in words is key.
The “primary” label refers to dyslexia when it is a result of a genetically inherited condition. This means if a child has a parent with dyslexia, they are more likely to have the learning difficulty themselves. Primary Dyslexia can cause difficulties processing sounds, letters and numbers, which negatively impacts on a child’s abilities in spelling, reading and math. Dyslexia not only runs in families, but tends to be seen more often in males, particularly those who are left-handed.
Due to infections, and sometimes poor nutrition in the womb, some babies experience brain development issues which can cause neurological impairment and result in dyslexia. Of the many types of dyslexia, Secondary or Developmental has been shown to respond best to treatment, including targeted phonics work through computer programmes.
Trauma Dyslexia also referred to as Acquired Dyslexia
When an adult or child has a brain injury from trauma or disease, they can sometimes develop difficulties with language processing, which result in dyslexia.
There are other types too. For example Balance Theory focuses on people’s behaviour in reading to suggest several types. Perceptual Dyslexia, is when people have trouble recognizing whole words, which causes slow reading.
Linguistic Dyslexia is when they read quickly but make mistakes and Mixed reflects both conditions. Individuals may also present Auditory, Spatial or even Math Dyslexia.
Teaching solutions for dyslexia
Teachers can help dyslexic students in the classroom by being aware of learning difficulties and providing extra time for students to process and learn new material. For example, children can benefit greatly by specifically learning how to read sight words.
These are service words and prepositions that are commonly found in classroom reading materials. Nonetheless, they can be difficult words for dyslexic children to remember as they are less amenable to mnemonic devices. Teaching sight words through extensive repetition via a computer spelling programme is often the best solution.
Allowing students to type assignments when possible is another good strategy. It can help reduce the time a dyslexic child needs to complete assignments by removing the mechanics of writing from the task, and giving them access to Spell Checkers.
You may also try to teach specific strategies for spelling. Above all, provide plenty of praise. Developing literacy skills is a challenge and your students will need the encouragement. Learn more about teaching students with dyslexia.
Learning solutions for dyslexia
Approaches may vary depending on the symptoms, but most dyslexics respond well to technology that breaks learning down into bite-size units. It allows them to proceed through a course at their own pace, learning one step at a time and repeating modules until they are ready to move on.
The Touch-type Read and Spell Course has been successfully used to help children and adults with dyslexia learn to type in a unique way while strengthening their phonics, reading and spelling skills, and improving their self-esteem as it helps them to feel and be successful.
