Education students present research at Faculty’s Annual Postgraduate Research Conference
A total of 145 postgraduate students and 55 staff members attended the University of the Free State’s (UFS) Faculty of Education Annual Postgraduate Research Conference Social Media.

“Exploring Grade 12 learners’ substance abuse and its influence on their academic performance”, “The role of the School Management Team in addressing Homophobic Bullying in Xhariep public schools” and “Exploring the use of YouTube videos in the teaching and learning of fractions in Grade 4.” 

These were some of the interesting research titles that were presented at this year’s University of the Free State’s (UFS) Faculty of Education Annual Postgraduate Research Conference. The two-day conference, now in its fifth year, took place from 6-7 October with the theme “Changing the Educational Landscape in Africa through ongoing research”. The conference is one of the faculty’s main events supporting its postgraduate students and ensuring time for completion for each one of them. 

A total of 145 postgraduate students and 55 staff members attended the conference where the faculty’s postgraduate students get exposure to present their research in front of an academic audience.

Prof Loyiso Jita, the Dean of the Faculty of Education, delivered the keynote address and spoke at length about the graduation rates of master’s and doctoral students in the faculty. He challenged the presenters to hold themselves and each other accountable for progression in their studies and to produce high-quality research that will position them and the university in good stead nationally and internationally. 

New teaching approach   

In the study “Exploring the use of YouTube videos in the teaching and learning of fractions in Grade 4”, MB Tsoaela (PhD student), explores the teaching and learning of fractions using YouTube videos in Grade 4. In trying to answer the main research question, “How do Grade 4 educators teach fractions utilising YouTube videos?” The researcher states that: “The use of YouTube videos is a very new way of learning in the South African context. This new teaching approach has proven to be exciting for young learners in Grade 4 because it has many options like animations, colourful videos, and pictures. Even though YouTube learning is exciting and fun, its implementation has challenges such as teachers wanting to use a chalkboard. Another challenge is the current load shedding.” 

Psychosocial implications of school violence

Another PhD student, MDL Stack, investigated how to design an assessment for Higher Education that ChatGPT is unable to provide an answer that will pass without human intervention in his research paper titled “Investigating an assessment design that prevents students from using ChatGPT as the sole basis to pass assessment in Higher Education at undergraduate level”. He argued that “ChatGPT has presented significant challenges to lecturers when they set assessments at tertiary level. 

“There is enormous potential for students to attempt to use ChatGPT to write and pass assessments designed at undergraduate level,” the researcher writes. 

Another research paper looked at the psychosocial implications of school violence on teachers in Motheo District public schools in the Free State, arguing that school violence against teachers continues to be a phenomenon that is increasingly disturbing, while having serious implications on South African and global societies. Many teachers suffer social and psychological stress but not much has been done to understand learner-induced violence against teachers.

Exposure for students  

Prof Matseliso Mokhele-Makgalwa, the acting Vice-Dean Research and Postgraduate Studies, says the purpose of the conference is to give exposure to master’s and PhD students to present their work in front of an academic audience (staff and students) as well as for them to get comments and feedback from experts and fellow students on their on-going research studies. 

“The conference is about sharing the ongoing research being done by our master’s and doctoral students and/or reporting on their preliminary and final outcomes of the students who are about to graduate. By presenting their work, they disseminate key findings, build relations with other students and staff, and create inter- and multi-disciplinary networks for future collaborations,” says Mokhele-Makgalwa.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
