For sustainable engineering to contribute to sustainability, curricular reforms are needed to train sustainability-conscious engineers. Examining student perceptions of sustainability education can provide insights for benchmarking the current quality of a curriculum and for identifying strategies for reforming a curriculum. Thus, the goal of this study was to examine student interest in, knowledge of, and experiences related to sustainability in civil and environmental engineering (CEE) at the Georgia Institute of Technology (Georgia Tech). A survey was developed and administered to students () enrolled in CEE capstone courses. The results indicated that although students are interested in sustainable development, there is potential for further enhancing sustainability learning. In addition, students reported that CEE courses strongly impacted their learning, which underscores the importance of curricular quality. Finally, although students were generally satisfied with CEE sustainability education, they cited the need for more guidance on integrating sustainability into the design process. Although this case study provides feedback to improve CEE sustainability education at Georgia Tech, it also serves as an example for other programs interested in evaluating their curricula from a student perspective.

Previous sustainability engineering education studies have suggested the importance of problem-based learning, project-based learning, team-based learning, and interdisciplinary learning. Place-based learning, interacting with outdoors, and building sustainable communities are also important aspects of sustainability education, yet relatively little has been published on how to use these pedagogical approaches in engineering education. The goal of this paper was to illustrate the implementation of all these pedagogical approaches in a graduate-level sustainability engineering education class. Fink's taxonomy of significant learning and the University of Toledo's Outdoor Classroom Garden provided the framework for this implementation. Throughout the semester, sustainability engineering students worked toward an engineering solution for how to water the University of Toledo's outdoor classroom garden. They also estimated the life-cycle cost and environmental impacts of their proposed solutions. The garden project and the design of the course provided many different learning opportunities that might be absent in a traditional civil engineering class. [ABSTRACT FROM AUTHOR]

An existing multidisciplinary course on sustainable engineering in developing societies was expanded to include sustainability issues and challenges faced in the developed world. The new course consisted of independent modules on general background, sustainability concepts and tools, sustainable water and waste systems, sustainable energy systems, sustainable agricultural and food systems, and sustainable building systems. The course included a semester-long project experience conducted in interdisciplinary teams. Projects were sourced from local businesses and institutions or from organizations involved in international development. Course evaluation included an end-of-semester self-assessment by students and an analysis of project reports. Thirteen out of 18 students surveyed (72%) agreed that their ability to consider techno-economic, environmental, and social aspects of sustainability was improved as a result of the course. An improved student understanding of aspects of sustainability and its measures was also evident in student project reports. [ABSTRACT FROM AUTHOR]

Environmental restoration is a matter of national concern. Decades of abuse by industry, agriculture, and the military have caused devastating contamination of the earth, air, and water. The Department of Energy alone will spend hundreds of billions of dollars on containment and restoration. It is imperative that restoration costs are minimized. Every dollar spent on restoration is a dollar that will not go toward research, a dollar that will not go to upgrade our nation’s infrastructure. The work presented here uses cost as a decision variable in restoration projects. Contaminated sites frequently vary from one point to another in type and level of contamination. In addition, a single piece of property may contain several distinct contaminated areas, each of which has characteristics unlike any of the other areas. Thus one should look at optimizing the selection of remediation technologies to address the variation. A methodology has been developed that will optimize the selection of remediation technologies based on cost. This methodology uses geostatistics and dynamic programming to break a site into discrete cells and then select the optimal sequence of remediation technologies. [ABSTRACT FROM AUTHOR]

A method to evaluate students' application of sustainability principles into engineering design and problem solving was developed. Students were presented with two challenge questions that each posed a scenario. Students responded to one question and their answers were scored using a rubric that combined both analytic and holistic scoring criteria to account for sustainability principles. The rubric was iteratively developed and met standard measures of reliability and validity. Based on responses from primarily civil and environmental engineering students at three institutions, it was found that male students, seniors, and participants in many diverse learning activities (extracurricular service, internships, undergraduate research, and engineering design courses) achieved higher rubric scores. Scores on the challenge questions did not correlate to students' interests in sustainable engineering, which were measured using a Likert-based survey. A challenge-question approach to formative assessment may enable instructors to adapt curricula to foster student learning of implicit sustainability issues in engineering. The rubric may be used with a diversity of content-focused challenge questions as a tool for assessing students' holistic, sustainability-focused approaches to engineering. [ABSTRACT FROM AUTHOR]

Revised Bodies of Knowledge, constituent input, and student demand are motivating the incorporation of sustainability concepts in traditional engineering curricula. While a variety of methods are in development, ranging from introductory engineering courses to capstone experiences to graduate-level treatment, the addition of new topics in an already constrained curriculum is creating a dilemma for many engineering programs. This work presents an example of how sustainability concepts were incorporated in a traditional civil engineering program administered within a constrained four-year curriculum. Using a variety of the treatments recommended in the literature, United States Air Force Academy civil and environmental engineering students learn and apply sustainability concepts at multiple points and in various frameworks during their four-year programs. Student feedback coupled with learning assessments suggest this framework may provide a more generally applicable model for incorporating sustainability concepts within engineering curricula, with particular focus on the civil and environmental engineering disciplines.
