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.”

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
