Enhancing Chlorination Fundamentals for Water Treatment Technology IV Course Using On-Line Multi-Media

Abstract

The current paper demonstrates the use of on-line multi-media, i.e. "chlorination of natural waters" and "dissociation of weak acids" from Merlot database, to enhance teaching and learning for Water Treatment Technology IV course material. This database focuses on fundamental concepts for chlorination as one of the most prominent disinfection treatment technology processes in the world and in South Africa. The course is part of the curriculum for the bachelor of technology degree in civil engineering, water specialisation at the University of South Africa (Unisa). The evaluation of these Merlot learning objects shows that accessibility, interaction usability, learning goal alignment, adaptation and motivation may be achieved during learning.
