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.”

Researcher uses NRF funding for studies to conserve plant and animal life
2017-04-18

Description: Butterfly Tags: Butterfly

It is difficult to survey all different types of
plants and animals and is therefore necessary to
choose one representative group. Butterflies are
relatively cheap and easy to sample. They are
known to be linked to specific habitats and to
respond to human pressures, such as farming.

Earth is the only planet we know of that contains life. The variety of different plants and animals is remarkable: from the giant whales that swim our oceans, to the tiny mosses that grow on the shaded sides of rocks.  Many of these plants and animals are important to humans. For example, trees provide us with oxygen to breathe, bees pollinate our crops and owls control pests. More importantly though, we can tell a lot about society from the way it cares for nature. Humans are the custodians of the planet and the way we care for nature reflects the way we value life.

Dr Falko Buschke, Lecturer at the Centre for Environmental Management at the University of the Free State, is interested in understanding how the distribution of biodiversity [the variety of living things in nature] in time and space influences the way we should conserve and manage nature.

Earth is losing biodiversity faster than at any time in human history
The planet is losing biodiversity faster than at any time in human history. “There is an urgency to conserve plants and animals before they are lost forever. Nature is complex, so the way we study it should embrace this complexity. We should not rely on limited data on one type of species from one place and assume that it will also apply elsewhere. Instead, it is important that biodiversity research is comprehensive in the types of plants and animals while also considering that ecological and evolutionary processes vary through time and across geographic space,” he said.

To conduct his research, Dr Buschke uses a variety of research tools, including biological data surveyed directly from nature, spatial data from satellite remote sensing and geographic information systems databases, and data generated though custom-built computer simulations.

"There is an urgency to conserve
plants and animals before they
are lost forever."

Field work in the eastern Free State
Although parts of the eastern Free State are considered a global priority for biodiversity conservation, it is mainly privately owned commercial farmland. This means that it is important that plants and animals can survive despite living side by side with agricultural production.

“My project investigates whether the sandstone outcrops, known as inselbergs (island-mountains), are safe havens for plants and animals. Because it is difficult to survey all the different types of plants and animals, it is necessary to choose one representative group. That is where butterflies come in. Butterflies are relatively cheap and easy to sample. They are known to be linked to specific habitats and to respond to human pressures, such as farming,” he said. “Once this butterfly data is collected, it can be linked to satellite information on plant growth patterns. This will provide a clearer picture of whether plants and animals can persist side-by-side with commercial agriculture”.

Dr Buschke has just begun surveys that will carry on until the end of this year. “This 12-month project is funded under the Foundational Biodiversity Information Programme through the South African National Biodiversity Institute (SANBI) and the National Research Foundation (NRF).
