All 23 grade 10 learners taking part in the University of the Free State’s (UFS) Creative Clubs Programme were awarded medals at the Bloemfontein regional Eskom Expo for Young Scientists (EYS) competition from 3 to 5 August 2023.

The learners, who attend Bloemfontein township schools, had been working on their projects for over a year as part of the Creative Clubs Programme, which is run by the UFS Faculty of Education. Guided by veteran Expo facilitators Dr Angela Stott and Coretha van den Heever, they attended 30 sessions on the UFS South Campus, with a total of 140 hours of face-to-face contact time, coupled with many hours of individual work at home, to prepare for the competition.

Their hard work paid off handsomely, with all 23 learners (who worked on 21 projects) achieving medals: six bronze, seven silver, and eight gold. Additionally, five of the learners won best-in-category awards, three won SA Youth Water prizes, and three were shortlisted for the international EYS competition.

“As an introvert, I found it difficult to explain my project to people, but I’ve developed communication skills and confidence through Expo,” said 15-year-old Nicolas Hugo, from Kagisho Secondary School, whose project won a gold medal. Nicolas studied water pollution levels at two inflow sites in the Bloudam catchment area, as well as the dam itself and its outflow, showing the astounding cleaning effectiveness of water reeds.

In addition to his gold medal he won the prize for the best project in his category, a special award in the category of water projects, and for the Best Development Project.

The UFS has a strong commitment to community engagement, and has been working with township schools throughout the province via school-university partnerships for over a decade. The 2023 Bloemfontein EYS competition celebrated the legacy of these partnerships not only through the 23 learners who were directly involved in the UFS programme over the past year, but also through the participation of 14 learners from two schools (Senakangwedi and Setjhaba Se Maketse) in Botshabelo as a direct result of the UFS’s work in those schools in the past. Before UFS ended its partnership with these schools, learners who had been involved in Expo programmes conducted by Dr Stott established science clubs in their schools. These clubs have continued to operate years after UFS exited the schools and the founding learners matriculated. This year these clubs yielded the winning project, Solar Power Stand, by Simthembile Hlahliso and Kabelo Sekoere from Senakangwedi High School.

Many of the learners said they have learned important skills through this process. “I didn’t know how to use a computer, but now I’m so good,” said Sylvia Hlangabeza, who won a gold award.

“I’m so proud of her, I cried,” said Sylvia’s proud mother.

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS
2015-12-07


Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.


Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
