Archaeological excavations in the Wonderwerk Cave, north of Kuruman in the Northern Cape.
Research fellow Dr Lloyd Rossouw from the Department of Plant Sciences at the University of the Free State (UFS) recently published an article in the Nature Ecology and Evolution journal with Dr Michaela Ecker from the University of Toronto as lead author, and Dr James Brink, research fellow at the UFS Centre for Environmental Management. The findings described in “The palaeoecological context of the Oldowan-Acheulean in southern Africa” provides the first extensive paleoenvironmental sequence for the interior of southern Africa by applying a combination of methods for environmental reconstruction at Wonderwerk Cave, which have yielded multiple evidence of early human occupation dating back almost two million years ago.
Where water once was
The Wonderwerk Cave is found north of the Kuruman hills (situated in Northern Cape) a 140m long tube with a low ceiling. The surroundings are harsh. Semi-arid conditions allow for the survival of only hardy bushes, trees, and grasses. But during the Early Pleistocene, stepping out of the Wonderwerk Cave you would have been greeted by a completely different site, the researchers found. Using carbon and oxygen stable isotope analysis on the teeth of herbivores (Dr Ecker), fossil faunal abundance (Dr Brink), as well as the analysis of microscopic plant silica remains (phytoliths) excavated from fossil soils inside the cave (Dr Rossouw), the results show that ancient environments in the central interior of southern Africa were significantly wetter and housed a plant community unlike any other in the modern African savanna.
What difference does it make?
While East African research shows increasing aridity and the spread of summer-rainfall grasslands more than a million years ago, the results from this study indicate an interesting twist. During the same period, shifts in rainfall seasonality allowed for alternating summer and winter-rainfall grass occurrences coupled with prolonged wetlands, that remained major components of Early Pleistocene (more or less the period between one and two million years ago) environments in the central interior of southern Africa. That means our human ancestors were also living and evolving in environments other than the generally accepted open, arid grassland model.
Empowering teachers: Working with head, heart and hand

The implementation of Curriculum 2005 brought about new demands in the teaching and learning of languages. In teaching languages, it is expected of teachers to focus on the development of the basic language skills which are embedded in the first four outcomes, namely listening, speaking and reading which is coupled with viewing and writing.
Although the learning outcomes are developed as an integrated whole, each one needs special attention. According to the NCS, the third learning outcome namely "reading and viewing", is stated as follows: "The learner will be able to read and view for information and enjoyment, and respond critically to the aesthetic, cultural and emotional value in texts".
Julia Ramabenyane researches The facilitative role of Grade 1 teachers in the development of reading skills in Sesotho. Empowering teachers: Working with head, heart and hand, a workshop for Grade 1 teachers, was held on 27 and 28 May in the Winkie Direko Building on our Main Campus. The aim of the workshop was to create an opportunity for teachers to better understand their role as facilitators in the development of reading skills.
In addition to the facilitation of Mrs Ramabenyane, Prof. Hasina Ebrahim (lecturer at the School of Social Sciences and Language Education), grade 1 teachers from Lesedi and Karabelo Primary Schools, as well as the HOD of Foundation Phase and three grade 1 learners from Karabelo Primary School in Rocklands, participated in the activities.
This workshop, together with other reflective group sessions, formed part of the emancipatory action research of Julia Ramabenyane's Foundation Phase PhD studies. This PhD study is titled The facilitative role of grade 1 teachers in development of readings skills in Sesotho.
