Serious game aims to alleviate statistics headache
When it comes to learning and understanding statistics, many students see the subject as a daunting challenge leaving them not only demotivated but also frustrated – sometimes even before starting the module at university. When the academic support departments of the North-West University’s (NWU's) campus in Vanderbijlpark set out to identify…
Teachers without borders: reaching out to educators
The 21st century is a challenging time and it is important that both teachers and school learners become self-directed learners. The North-West University's (NWU's) research focus area for Self-directed Learning (SDL), under the directorship of Prof Elsa Mentz, focuses especially on indigenous knowledge for self-directed learning in the science…
Special Economic Zone in Mahikeng: viable but not a cure-all
A Special Economic Zone (SEZ) in Mahikeng, with an agro-processing focus, could hold economic benefits for the city and the North West Province - provided there is sufficient policy and planning support. This is according to a study done by the TRADE research entity at the North-West University (NWU) at the request of the North West…

The CRB focuses on adding value to the SA national mineral and chemical resource base found in the North-West and Southern Gauteng provinces. This can be divided into two key knowledge areas, i.e. metal-based resources (such as the platinum group metals and chromium) and carbon-based resources (such as petrochemicals, plant oils and…
