Students with dyspraxia (DCD) can also have comorbid language impairments (SLI). While these developmental disorders are distinguished by the domain of principal deficit, they are both associated with significant learning difficulties. Studies that followed 7-year olds with dyspraxia found that they struggled with reading and comprehension by the time they were 10 years old. I wanted to know whether the combination of motor coordination difficulties plus language impairments lead to worse learning outcomes compared to those with only motor coordination difficulties or language impairments. I looked at three groups of students: 1) those with SLI but no dyspraxia; 2) those with dyspraxia but normal language skills; 3) those with dyspraxia + language impairments.

There were two key findings. First, visual-spatial memory was the single best test to successfully distinguish a student with dyspraxia from those with language impairments. If you have a student with dyspraxia but normal language skills, their memory profile is the same as those with dyspraxia + language impairments: they will have marked difficulties in visual-spatial working memory. The second finding was that despite relative strengths in language, those with dyspraxia but no language impairments performed as poorly as the group with dyspraxia + language impairments. This means that for a student with dyspraxia their working memory abilities determine their learning difficulties. Any strength in language that they have is not able to sufficiently support their learning. If their working memory is not addressed, then any additional strengths they have, such as in language, will not provide a sufficient platform for learning.

In the last few years, there have been various claims in the media on how simple exercises like jumping jacks and balancing can make children smarter.  In the UK, it was a matter of heated debate when a psychologist suggested that such exercise can actually improve reading skills. So is there any basis to these claims?

Well, yes and no. Let’s first look at the evidence for whether motor skills improve as a result of these exercises. If the exercise is simple like skipping, then you notice improvement in skipping skills very quickly. However, if the exercise is relatively complicated like hockey-puck shooting, then there is very little improvement, even after over 1000 practices!

What about learning? In a recent study, I asked students with learning difficulties and motor problems to take part in a 13-week exercise program. In addition to Brain Gym, they also did different balancing exercises, as well as trained their fine and gross motor skills.

You will probably not be surprised to learn that these students had better motor skills compared to the group that did not take part in this exercise program. However, these increased motor skills did not result in better reading and math scores! These students were still struggling in their academic attainments.

What does this mean? While I am certainly not discouraging exercise, this study, and a growing number like this, illustrate that it’s not enough to ask students to do some jumping jacks and skipping if we actually want to help them do better in the classroom.
