Web-based interactive computer-aided learning package on open-channel flow: Innovations, challenges, and experiences

In this paper, the development and implementation of a web-based interactive computer-aided learning package on open-channel flow is delineated. The principal purpose of the tool is to support classroom teaching for a better understanding of the basic principles and practical aspects of the theories on open-channel flow. Several up-to-date expert-system shell and web-production software are employed during its development. Various theories on open-channel flow, design, and interactive "What-if" analysis on various design parameters are performed using this package through an active and dynamic learning environment. Through evaluation of its learning effectiveness and teaching efficiency, in comparison with traditional course delivery, pertinent innovations, challenges and experiences on the possible impact the Internet is having in the field of engineering education are discussed. It is shown that, if used appropriately, web-based learning has the potential to enhance both learning effectiveness and teaching efficiency.
