UFS researcher programme aids pupils with ADHD and dyslexia
Dr Carol Goldfus

Many years ago, as a secondary school teacher, Dr Carol Goldfus from the University of the Free State’s Unit for Language Facilitation and Empowerment, realised that reading comprehension ought to be the focal point of teaching. She came to the conclusion that many adolescents were unable to gain fluency in English as a foreign language despite many years of study and that there were those who struggled with the foreign language. With her postgraduate specialisation in neuroscience and the merging of neuroscience and education, she developed a reading comprehension intervention programme.

Reading remains important

Contrary to what we believe, the world is not more visual – but rather more technical, Dr Goldfus explains, and reading with understanding remains of utmost importance in the twenty first century. “Literacy does not only mean reading, but also thinking fast,” she says, “with the ability to sift through the mass of available information. Without reading proficiency, people cannot succeed in a world with so much information. In fact, the ability to identify what is important, and what not, is more crucial than before.”

““It is our duty to give
pupils worldwide the ability
to cope with a sophisticated,
alienated, and technological world.”

One brain, many languages

Reading comprehension is the epicentre of Dr Goldfus’s approach to learning, and her intervention programme may benefit any pupil who is unable to cope with the demands of the academic setting, and can be applied to any language. These pupils include children from seventh to twelth grade (12 to 18 years of age) who read without comprehension, have dyslexia, dyscalculia (problems with maths), and ADHD (Attention Deficit with or without Hyperactivity), or have dropped out of an education setting. “My intervention programme is in English as a Foreign Langue (EFL) but is not static, since it is based on principles from neuroscience and linguistics that are placed in the world of education. Although it is for EFL, it has a backwash effect on mother-tongue reading competence as well. Each programme comprises certain core principles, like developing self-esteem, monitoring comprehension and learning, and developing long-term memory storage. Without remembering, there is no learning.”

No one wants to fail

Dr Goldfus feels that it is our duty to give pupils worldwide the ability to cope with a sophisticated, alienated, and technological world. “My goal is to turn failure into excellence through an understanding of how the brain works. That is what the programme and my research can offer: creating a brain that can support learning where each pupil can fulfil his or her potential.”

Her work is so noteworthy, that Dr Goldfus received a Blue Skies Grand from the National Research Foundation of South Africa for her research: Graphomotor synchronisation to musical stimulation as a diagnostic tool for dyslexia. This proposed interdisciplinary research addresses dyslexia, a language-related disability, through the language of music and encompasses three disciplines: music cognition, physics and education.

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
