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 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.

Crystals and crystallography form an integrated part of our daily lives, from bones and teeth, to medicines and viruses, new catalysts, jewellery, colour pigments, chocolates, analysing rocks on the moon and Mars, electronics, batteries, metal blades in airplane turbines, panels for solar energy and many more.

In spite of this, not many people know much about X-ray crystallography, although it is probably one of the greatest innovations of the 20th century, spanning the sciences. That is why this discipline is actively researched by a number of tertiary institutions around the globe as well as the Inorganic Chemistry Group of the Department of Chemistry at the University of the Free State (UFS).

Research by the Inorganic Chemistry Group includes:
•    clever design of model medicines to better detect cancer and study heart, bone and brain defects;
•    production of new compounds for making new and better automobile fuels and decrease carbon dioxide in the atmosphere;
•    generation and purification of new South African mineral resources for metals widely used in turbines which use wind energy.

A group of UFS students have received acknowledgement for their research at six international venues in the past few months.

Posters in Cameroon
Twelve postgraduate students, together with Prof André Roodt, Head of the Inorganic Chemistry division at the UFS, delivered three oral presentations, nine posters, one plenary and one keynote lecture abroad.

Four UFS students - Nina Morogoa, Pheello Nkoe, Alebel Bilay, and Mohammed Elmakki - who delivered posters at the First Pan African Conference on Crystallography in Dschang, Cameroon, received prizes for their presentations.

School and conference in Croatia

Students Orbett Alexander and Dumisani Kama were selected to attend the intense and demanding Third European Crystallographic School in Bôl, Croatia. Both Kama, Alexander and Prof Roodt gave oral presentations at the 24th Croatian-Slovenian Crystallographic Meeting at Brac Island, Croatia.

Kama, together with Dr Ferdi Groenewald, Dr Carla Pretorius and Pennie Mokolokolo, also attended the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The ESRF is a centre of excellence for fundamental and innovation-driven research. The storage ring at this laser facility can generate X-rays 100 billion times brighter than typical medical and laboratory X-ray sources.

Research in Switzerland

Kama and Mokolokolo also spent one month on research visits at the University of Zurich in Switzerland. Both Kama and Alexander were invited to present their research orally to the Institute of Inorganic Chemistry in Zurich, headed by Prof Roger Alberto.

In Basel, Switzerland, Dr Ferdi Groenewald, Dr Renier Koen, and Dr Truidie Venter all presented their research at the 30th European Crystallographic Meeting.

Prof Roodt said: “It is incredibly important that our postgraduate students get the chance to interact, discuss, and be taught by the best in the world and realise that hard work on basic and applied chemistry processes leads to broader recognition. The delegates to these international venues came from more than 60 countries and took note of our students work. With these young researchers, our future at the UFS and at Inorganic Chemistry is in good hands”.
