Christa Faber
Innovative Methods in Assessment Practices award winner for the Qwaqwa Campus, Christa Faber.

By working with students and being part of their development into successful young adults, Mathematics and Applied Mathematics Lecturer on the Qwaqwa Campus, Christa Faber, soon realised that she would like to proceed with her own studies, and she set her sights on just that. Obtaining her honours degree in Mathematical Statistics at age 40 inspired Faber to continue pursuing an education. She will be receiving her Master of Higher Education Studies degree during the December graduations.

Teaching has always been her passion, Faber shared fondly. She commenced her teaching career as a Mathematics teacher in a small town, Molteno, in the Eastern Cape. After four years of teaching, she worked as a Mathematics supply teacher in the United Kingdom for two years. Upon her return, she continued her teaching career in Harrismith, where she was appointed as a Science teacher at Harrismith High School, before receiving an offer to assist the UFS Qwaqwa Campus as a Statistics facilitator in 2003. She never looked back.

As a researcher, Faber has spent the past eight years using technology as an educational tool to determine whether it can be used to improve students’ performance and understanding of basic statistics. “I believe students learn best when they expect to be successful and see the value of the course for their personal development,” she said.

Faber conducted an experiment on how an online assessment tool (OAT) could be incorporated into the Statistics module to enhance student engagement, and consequently, the performance of students in a rural setting. The transition from face-to-face teaching to online learning has been a topic across all institutions of higher learning, with students’ response to learning on blended platforms being of great importance.

The learning experiment, conducted pre-COVID, showed the benefits that online assessment tools could have on the performance and engagement of students at a rural university. Faber said she considers it important to know how students engaged in key online and general learning practices as a way of managing and developing rural university education. For the experiment, a pragmatic parallel mixed methods design was used to divide students into two groups to compare the performances of those with online assessment tool interventions and those without.

The intervention recently won Faber the Innovative Methods in Assessment Practices award for the Qwaqwa Campus at this year’s Centre for Teaching and Learning awards. The purpose of the category was to showcase how assessment strategies, tools, and assessment activities are used to assess students in new, original, or inventive ways. She said she was grateful to receive recognition for a research project inspired by her passion for teaching and learning, combined with the use of online assessment technology, to enhance students’ learning experience in the field of statistics. “My ongoing research supports the promotion of student engagement in statistics education, as well as in the general educational field.”

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
