Sustainable Engineering Assessment Using Rubric-Based Analysis of Challenge Question Responses

Abstract

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.
