A Computer Assisted Learning (CAL) approach was developed to enhance course material for an undergraduate Hydrology and Water Management course, through the use of multimedia courseware. The courseware can be installed under 32bit versions of Windows' operating systems. CD-ROM's were used as the courseware distribution media. A LAN version, which uses NetBEUI protocol to access Windows' workgroups, has also been activated. / Course material was first digitized and then placed in a Windows' Graphic User Interface (GUI) using Microsoft Visual Basic versions 4--5. Multimedia files, including images, sound, and movies were then added to enhance visualization. Students can navigate through the courseware in a non-linear fashion akin to multimedia hyperlink technology. The courseware contains all of the conventional course material in text format with multimedia additions so that students can follow class material on computers. Simulation and prediction tools were also added in order to aid students in problem visualization and solving. / The course instructor can update material by uploading material through an ActiveX web site. The courseware is then automatically updated when an active TCP/IP connection is detected on the client side using a similar ActiveX control. / Program performance is optimized through the use of a high-speed CD-ROM drive and at least 32 megabytes of RAM. The network version performs substantially slower than its CD-ROM equivalent since a Network bandwidth bottleneck occurs.
