Singh, U. G; De Villiers, M. R. (Ruth) (Unisa Press, 2012)

Open distance learning (ODL) is characterised by increasing numbers of students who are geographically dispersed. Assessment (marking) can be complex --efficient means of assessment are required, but this should not ...
A qualitative study on software application usage and user behaviour at South African Digital Doorway sites

Gush, Kim; De Villiers, M.R. (Ruth) (2011)

Digital Doorways are rugged multi-terminal computer systems for promoting self-directed, unassisted or peer-assisted leaning in low-income communities where computer infrastructure is limited. Users develop the necessary ...
Learning with an e-learning tutorial: Cognition and the value of errors

De Villiers, M.R. (Ruth); Becker, Daphne; Adebesin, Tawakkaltu Funmilola (2012)

E-learning tutorials provide engaging learning activities and feedback assupplementary study material for distance learners. Relations is an interactive, CD-based, multi-media tutorial, custom-built to foster mathematical ...
Evaluation of a Collaborative Learning Environment on a Facebook Forum

De Villiers, M.R. (Ruth); Pretorius, Marco Cobus (2013)

An academic group and discussion forum were established on Facebook for a cohort of postgraduate students studying ‘Concepts and Principles of eLearning’. The Forum had a constructivist, student-centric ethos, in which ...
Virtual Reality Training Applications for the Mining Industry

Van Wyk, Etienne; DeVilliers, Ruth (2009)

Virtual reality is a rapidly growing technology which utilises the ever-increasing power of computers to simulate real-world and imaginary environments and situations with a high degree of realism and interactiveness. Safety ...
Software usage in unsupervised digital doorway computing environments in disadvantaged South African communities: Focusing on youthful users

GUSH, KIM; De Villiers, M.R. (Ruth) (2011)

A framework for usability evaluation of an offline e-learning tutorial and its application in usability testing

Nyang’or, J.O.; De Villiers, M.R. (Ruth); Ssemugabi, Samuel (2013)

The design of e-learning environments should take into account principles of learning and principles of usability. To achieve this, e-learning applications should undergo usability evaluation and subsequent refinement. The ...
A comparative analysis of the meaning of ‘learnability’ for child and adult users

Chimbo, Bester; Gelderblom, J.H.; De Villiers, M.R. (Ruth) (2011)

The learnability principle relates to improving the usability of software, as well as the user’s performance and productivity. The latter suggest that the principle was formulated mainly with the adult user group in mind. ...
Design-based research – the educational technology variant of design research: Illustrated by the design of an m-learning environment

De Villiers, M.R. (Ruth); Harpur, P.A (2013)
