Dr Monique de Milander, Lecturer in Exercise and Sport Sciences at the UFS, is leading research on attention-deficit hyperactivity disorder (ADHD) and visual and motor control difficulties.

 

Research done by the University of the Free State (UFS) has shown that Grade 1 learners not only experience visual problems, but also developmental coordination disorder. Teachers and parents can help to identify this.

In the first study published in the South African Journal of Child Health (https://doi.org/10.7196/SAJCH.2021.v15i1.1705), Dr Monique de Milander, Lecturer in Exercise and Sport Sciences at the UFS, led research on attention-deficit hyperactivity disorder (ADHD) and visual and motor control difficulties.

“Visual problems are often overlooked and are seen as a hidden disability. Thus, children are labelled as ADD/ADHD, but in fact, they have learning-related visual problems. Our eyes connect the world with the brain, and we receive 80-90% of information from our eyes. Consequently, visual problems lead to poor vision, and these visual problems will interfere with children’s ability to learn in the classroom,” she explains.

During the study, ADHD symptoms were found to be significantly associated with half of the visual functioning difficulties. These skills include fixation – the ability to fixate on a stationary object with both eyes – in addition to fixating with the eyes independently. 

Ocular alignment of the right eye was indicated as a problem – the ability of the two eyes to work together in order to view an object clearly. Therefore, the eyes must move in a coordinated manner. Visual tracking was the skill that the children struggled with the most in both screening tests; thus, to follow a moving object. This was found for both eyes – the right eye on an X shape, and the left eye on a circle. 

She added that science suggests that although children at the age of five or six can perform a variety of manipulative skills such as catching, throwing, kicking, and hitting, the manipulative skills that require visual tracking or the ability to intercept moving objects, develop somewhat later (eight years) due to the sophisticated visual-motor requirements. 

Furthermore, although maturation plays a role in achieving these skills, children need opportunities to practise the skills in a variety of settings. Parents and teachers should encourage children to take part in physical activities and sports, in addition to proper instruction on how to perform the manipulative skills.

How will these visual difficulties be identified?

It is important to note that children can fixate, visually pursue objects, and reach accurate decisions about the size and shape of an object; however, some refining still has to take place. In other words, the perceptual abilities of the young child are not yet complete. Some examples of visual perception problems in a young child, as indicated by perceptual motor skills involving the eyes, are as follows: 
    
1. Using control to intercept a ball 
2. Interchanging letters and numbers
3. Poor perception of moving objects
4. Poor figure-ground perceptual abilities
5. Distance perception
6. Anticipating timing

What is the next step after identifying visual difficulties?

The first aspect to take into consideration is the age of the child since we now know that their perceptual abilities need to be refined. If the problem continues, screening tests can be done. If the child is at risk, it is recommended that the parent see an optometrist who specialises in visual problems.

How does one assist a child with ADHD in the classroom?

Five tips for teaching students with ADHD:
1. Change activities frequently to accommodate short attention span
2. Use a positive behaviour modification programme to keep student focused on task
3. Incorporate 3-5 min of conscious relaxation at the end of the physical education period
4. Give brief instructions
5. Use activities that promote cooperation among all students

In another study led by Dr De Milander and published in the South African Journal of Childhood Education (https://sajce.co.za/index.php/sajce/article/view/930), the early identification of learners with developmental coordination disorder was researched.


In children experiencing poor motor skills (fine and gross motor coordination difficulties), without evidence of a neurological disorder and which cannot be linked to a general medical difficulty such as cerebral palsy or a pervasive development disorder, the low motor skills are significant – to such an extent that it interferes with their social competence, academic performance, and physical development, leading to problems with completing daily activities, Dr De Milander explains.

The characteristics of developmental coordination disorder are:

• Experiencing problems getting dressed and tying shoelaces
• Finding it difficult to run, skip, or jump
• Experiencing problems with visual perception 
• Poor pencil grip
• Slow and hesitant movement
• Poor spatial concepts about in front, behind, next to, below, and above 
• Unable to catch or kick a ball
• Finding it difficult to work in group context

She gives the following advice: Children should be motivated and challenged to participate in simple, yet enjoyable and relaxing physical activities. The focus should be on the child's strengths and not his/her weaknesses. Allow the child to play regularly in sandboxes and with clay. Improve the child’s ball skills by catching and throwing. Motor skills must be learnt through simple mastery steps. Improve the child's movement skills and make participation in movement activities enjoyable and challenging. Concentrate on reaction skills and play in which the child can participate. In extreme cases, specialised treatment by an occupational therapist and a kinderkineticist is important.

It is important to know that children do not outgrow these disorders as previously believed; therefore, many children still experience these difficulties as adolescents. Thus, if your child is experiencing any problems, take cognisance of the problem and address it as soon as possible. Professionals such as kinderkineticists are available in private practice and at various schools to assist your child in improving a variety of deviations. The kinderkineticist can evaluate your child through a standardised test to determine the problem, and then suggest an intervention to address the specific problem, as well as to prevent secondary problems such as low self-esteem, physical inactivity, overweight and obesity, etc., which are associated with these disorders.

For help, visit the website of the South African Professional Institute for Kinderkinetics (https://kinderkinetics.co.za/) where you will be able to find a kinderkineticist in your area.

Kinderkinetics is a profession aimed at promoting and optimising the neuromotor development of young children (0-13 years) through science-based physical activity.  All programmes within this profession have a preventative, stimulating, developing, and rehabilitative nature. In summary, it has the following goals:

• Promoting functional growth and proper motor development in young children.
• Focusing on certain movement activities to promote/facilitate sport-specific skills.
• Implementing appropriate rehabilitation programmes for children with growth and/or developmental disabilities in order to maintain an active, healthy lifestyle.

Researcher takes home gold at international Famelab competition

Recently, University of the Free State (UFS) Centre for Environmental Management master’s student, Tshiamo Legoale, was announced the FameLab International champion at the Cheltenham Science Festival in the United Kingdom. She is probing methods to use wheat as a gold hyper-accumulator – or, as she puts it, “grow gold from wheat”. The young researcher made South Africa proud by winning both the audience’s and the judges’ vote.

Coming back home a hero
“Winning was a surprise to me, because all 31 contestants had wonderful research. They all had really good presentations. I’m very grateful for all the support that I received from home. Social media showed me a lot of love and support. When I felt unconfident, they gave me ‘likes’ and that boosted my confidence a bit,” said Legoale about her win.

As South Africa celebrates Youth Month in June, Tshiamo represents hope for thousands of young South Africans to overcome difficult circumstances and follow careers in science.

The human impact is crucial, because Legoale’s win is not only scientific. It is also social and political. As a young female scientist in South Africa, she represented one of three African countries making it to the finals of FameLab, which has grown to one of the largest science communication competitions internationally.

With this in mind, Legoale says it may, in the end, be necessary to balance the needs of communities with the desire to increase yield. “Are we looking to make a fortune or are we looking to put food on the table?” she asks. “These are all things we consider when we conduct such research.”

World-class research from Africa
In South Africa, an estimated 17.7 million tons of gold is wasted. “All this gold was mined out previously, but tiny amounts remain in the dumps,” Legoale explains.

Her research focuses on the uses of wheat as a gold hyper-accumulator, which essentially means wheat plants are used to harvest gold from mine dumps. Simply put, the wheat is planted in the dumps, where enzymes found in the roots react with the gold and the plant absorbs it. The gold is then absorbed by every part of the plant, except the seeds, which means the next harvest can be used for food if need be.

“South Africa's world-champion young scientist, Tshiamo, represents all that is good about this country – brilliant, bright, and set for a fine future. I'm so proud that British Council SA, together with our partners SAASTA and Jive Media Africa, can help her along the way. Huge congratulations to her from all of us – it is a big win for Africa on the world stage,” said Colm McGivern, British Council South Africa Country Director.

The research represents a win on multiple levels. First, there are the obvious potential socio-economic benefits: food production, job creation, and phytomining is more economical than other contemporary mining methods.

Then there is safety. It is a more environmentally friendly practice than methods like heap leaching, carbon-in-leach or carbon-in-pulp. It is also safer for miners themselves, who will not be exposed to dangerous chemicals like mercury, which has been responsible for a great deal of toxicity in mine dumps. And it is safer for those living in the surrounds.
