In its quest to inspire excellence, the University of the Free State (UFS) is in the process of installing state-of-the-art microscopy instruments that will differentiate them as leaders in materials research.

This project to the value of R65 million will not only promote research in, among others, the fields of Chemistry, Physics, Microbiology, Geology, Plant Sciences, Zoology, and Cardiothoracic Surgery, but it will also increase the number of research articles published. 

Prof Koos Terblans, Head of the Department of Physics and Director of the Centre for Microscopy at the UFS, indicates that the university recently purchased a high-resolution transmission electron microscope (HRTEM), a scanning electron microscope (SEM), and a focused ion beam secondary electron microscope. 

“The installation of the equipment that was delivered on 1 March 2021 will take approximately three to six months,” he says. 

Research at another level

The biggest instrument, the HRTEM, allows for direct imaging of the atomic structure of samples. This powerful tool will allow researchers to study the properties of materials on an atomic scale. It will, for instance, be used to study nanoparticles, semiconductors, metals, and biological material.

The instrument will also be used to optimise heat treatment of materials, as it can heat the sample up to 1000 °C while recording live images of the sample. “With this apparatus, the UFS is the only institution in South Africa that can perform this function,” says Prof Terblans. 

He says to install the apparatus, they had to dig a hole of 2 m deep in a special room where the machine was to stand. The machine was then mounted on a solid concrete block (4 m x 3 m x 2 m) in order to minimise vibration. The instrument also acquired a special air conditioner that minimises the movement of air in the room. 

The focused ion-beam secondary electron microscope that was purchased, is used together with the HRTEM, explains Prof Terblans. It is used to cut out samples on a microscopic level to place inside the HRTEM. 

Having access to both the HRTEM and the ion-beam secondary electron microscope places the UFS at another level with its research, says Prof Terblans. 

At the forefront of microscopy 

The third machine acquired, the SEM – which is an electron microscope – allows researchers to produce images of a sample by scanning the surface of the sample with a focused beam of electrons. Prof Terblans says this machine will be used to serve researchers in the biology field with high-resolution SEM photos. 

The UFS Centre for Microscopy can, besides UFS researchers, be accessed by researchers from the Central University of Technology, the national museum, and other research facilities. 

With this injection of state-of-the-art equipment, the UFS is now more than ever at the forefront of research in South Africa.

Imagine a teaching approach that inculcates richness of culture and knowledge to individual learners, thus enhancing equity, equality, social justice, freedom, hope and fairness in terms of learning opportunities for all, regardless of learners’ diversity.

This teaching strategy was introduced by Mots’elisi Malebese, postdoctoral Fellow of the Faculty of Education at the University of the Free State (UFS), whose thesis focuses on bringing together different skills, knowledge and expertise in a classroom environment in order to enhance learners’ competence in literacy.

A teaching approach to aid Grade 4 literacy competency
Titled, A Socially Inclusive Teaching Strategy to Respond to Problems of Literacy in a Grade 4 Class, Malebese’s post-doctoral research refers to an approach that improves listening, speaking, reading, writing, technical functioning and critical thinking. Malebese, who obtained her PhD qualification in June this year, says her research confirmed that, currently, Grade 4 is a bottleneck stage, at which learners from a low socio-economic background fall behind in their learning due to the transition from being taught in their home language to English as a medium of instruction.

Malebese, says: “My study, therefore, required practical intervention through participatory action research (PAR) to create conditions that foster space for empowerment.”

PAR indoctrinates a democratic way of living that is equitable, liberating and life-enhancing, by breaking away from traditional teaching methods. It involves forming coalitions with individuals with the least social, cultural and economic power.

Malebese’s thesis was encouraged by previous research that revealed that a lack of readiness for a transitional phase among learners, teachers’ inability to teach literacy efficiently, and poor parental involvement, caused many learners to experience a wide variety of learning barriers.

A co-teaching model was adopted in an effort to create a more socially inclusive classroom. This model involves one teacher providing every learner with the assistance he or she needs to succeed, while another teacher moves around the room and provides assistance to individual learners.

“Learners’ needs are served best by allowing them to demonstrate understanding in a variety of ways, because knowledge is conveyed and accomplished through collaborative work,” Malebese said.

She believes the most important benefit of this model is assuring that learners become teachers of their understanding and experiences through gained knowledge.

Roleplayers get involved using diverse expertise in their field
Teachers, parents and several NGOs played a vital role in Malebese’s study by getting involved in training, sewing and cooking clubs every weekend and during school holidays. English was the medium of teaching and learning in every activity. A lodge, close to the school, offered learners training in mountain biking and hiking. These activities helped learners become tour guides. Storyteller Gcina Mhlophe presented learners with a gift of her latest recorded storytelling CD and books. Every day after school, learners would read, and have drama lessons once a week.

AfriGrow, an organisation that works with communities, the government and the corporate sector to develop sustainable community-driven livelihoods through agricultural and nutrition programmes, provided learners with seedlings, manure and other garden inputs and training on how to start a sustainable food garden. The children were also encouraged to participate in sporting activities like soccer and netball.

“I was aware that I needed a large toolbox of instructional strategies, and had to involve other stakeholders with diverse expertise in their field,” Malebese said.
