A Web-Based Learning Module for Teaching GIS within the Context of Environmental EngineeringThere is a growing need for teaching Geographical Information Systems (GIS) in engineeringdisciplines, such as environmental. However, there has been limited focus on GIS inundergraduate programs, since it’s difficult to fit a GIS class into the large number of classrequirements already included in engineering curricula. The purpose of this research is theevaluation of web-based learning module created by a multidisciplinary team at a Midwesterntechnological research university, which allows instructors to integrate GIS instruction intoexisting courses. This module is one part of a large scale National Science Foundation fundedproject in which GIS modules are being developed for several areas in civil engineering. Theprincipal goals of this evaluation are to determine the overall effectiveness of the module,identify the factors that mediate the effectiveness, and to determine ways in which the modulecan be made more effective.Data were collected from 56 students, 28 in an experimental group and 28 in a control group.Students in an experimental group participated in a laboratory session, which utilized themodule, to solve a problem on urban ozone events and census tract analysis; whereas students ina control group attended a class lecture covering the same information. Students in theexperimental group completed a questionnaire and students in both groups completed a quiz overthe material.Quantitative analysis was carried out on the quantitative portion of the scale for the experimentalgroup, and for both groups on the quiz. A qualitative analysis was applied to the open-endedquestionnaire items for the experimental group. Students in the experimental (learning system)section scored significantly higher on the quiz. Students in the learning systems group rated thelaboratory session as significantly more effective for learning, and more motivational than theclass texts. They also rated the lab significantly more applicable to real world engineering thanboth their text books and class lecture. The qualitative analysis revealed a number of ways thesystem can be further improved to make the module more effective.
