'Serious game' kan statistiekkopseer verlig
Aug 29, 2017 - Wanneer dit by die leer en begrip van statistiek kom, beskou talle studente die vak as ’n afskrikwekkende uitdaging wat hulle nie net gedemotiveer laat nie, maar ook gefrustreerd –soms selfs voordat hulle met die module op universiteit begin. Toe die akademiese ondersteuningsdepartemente van die Noordwes-Universiteit (NWU) se kampus in…
Serious game aims to alleviate statistics headache
Aug 29, 2017 - 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
Aug 29, 2017 - 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
Aug 29, 2017 - 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…
