New Way to learn a language
Spearheading the digital expansion of the conversational Sesotho course is IDEAS Lab Director, Johann Möller (middle). With him are from the left: Prof Pule Phindane, CUT; Dr Brenton Fredericks, CUT; Bahedile Letlala, UFS Department of African Languages; and Dr Elias Malete, UFS Department of African Languages.

For many years now, the UFS has been offering a one-year course in conversational Sesotho for staff members; this can then be followed up with the one-year course in advanced conversational Sesotho. The conversational Sesotho for students in the Faculty of Education was introduced in 2018 at the UFS.

The Central University of Technology (CUT) needed a conversational course for its first-year students and approached the Department of African Languages for the development of such a course. Living as we do in a multilingual country; this additional language skill opens doors and often hearts as well.


Using instructional design principles

However, the need was identified by both CUT and UFS to present this crucial information in a way that would be more appealing to digital natives as well as to those less familiar with technology. The Department of African Languages on the UFS Bloemfontein Campus, together with relevant departments from the CUT, approached the IDEAS Lab located on the UFS South Campus, since they already have a reputation for being a specialist on broadcasting and repackaging curricular content for digital presentations. The IDEAS Lab provided technical advice and built the multimedia programme, which will help the user to hear and practice phrases in Sesotho, using instructional design principles. The course will be available to both staff and students belonging to the two universities.

Room for growth

Johann Möller, Director of the IDEAS Lab, says this pilot programme will give both institutions the opportunity to test the use of multimedia for language acquisition. He adds, “Language is extremely complex, and we would like to expand this learning aid in the future.” In fact, the original design has room for growth built into it.

To keep things simple for the user and the building team, it was decided to start out with only four potential everyday scenarios where a staff member would like to speak Sesotho: Firstly, how to greet other persons from different genders; secondly, potential scenarios one might encounter in the university environment itself; thirdly, how to deal with situations at a hospital; and finally, how to use one’s language skills at a filling station.

Pronunciation is key

Each scenario contains three to four conversations that the learner can revise, along with images and audio that illustrate the situation and assist with correct pronunciation. The system does not allow the user to progress unless they have listened to the pronunciations of the sample sentences or phrases.

Further reading material and vocabulary lists are also provided, with the result that people who are using the programme can learn at their own pace. The authoring software Articulate Storyline was used to build the individual scenarios and each conversation or lesson within it. The lessons are also not dependent on an internet connection; they can be downloaded onto a flash memory drive and used offline.

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
