Development of An Interactive Computer Based Learning Strategy To Assist in Teaching Water Quality Modelling

The following paper presents a computer based learning strategy to assist in introducing and teaching water quality modelling to undergraduate civil engineering students. As part of the learning strategy, an interactive computer-based instructional (CBI) aid was specifically developed to assist students to set up, run and analyse the output from a commercially available water quality model (WQMAP) for a hypothetical raw sewage spill. The CBI aid comprised a Hypertext Markup Language (HTML) module with helpful text and still graphics, and links to on-screen recorded motion movie clips showing on-screen actions and voice narrations during the instructors absence. An anonymous class questionnaire to assess the students ’ perceptions of the developed approach found that most students felt they were able to complete the project with minimum supervision, and have acquired a basic understanding of water quality modelling as a result of the activity. Additionally, almost all of the students found the CBI aid helpful and easy to follow
