Stable Beginnings in Engineering Design.

Novel Engineering activities are premised on the integration of engineering and literacy: students identify and engineer solutions to problems that arise for fictional characters in stories they read for class. There are advantages to this integration, for both engineering and literacy goals of instruction: the stories provide ‘‘clients’’ to support students’ engagement in engineering, and understanding clients’ needs involves careful interpretation of text. Outcomes are encouraging, but mixed, in part owing to variation in how students frame the task. For instance, although students often pay close attention to the stories, interpreting and anticipating their fictional clients’ needs, they sometimes focus more on the teacher and what they think she would like to see. This variation occurs both within and across groups of students, and it motivates studying the dynamics of student framing. Here, we examine a pair of students who share a central objective of designing an optimal solution for their fictional client, and who persist in achieving their objective. We argue that the students’ stable framing of the activity involves their engagement in engineering design, and that the abilities they demonstrate in pursuit of a solution are evidence of their productive beginnings in engineering design.

Assessing students’ motivation to engage in sustainable engineering

Purpose – The purpose of this study was to design an assessment instrument to evaluate students’ attitudes toward sustainable engineering (SE). Factors that impact SE beliefs could then be explored. Design/methodology/approach – Using the definition of sustainability from the Brundtland report and expectancy value theory, students’ sentiment toward SE was evaluated using items to assess SE self-efficacy, SE value and SE affect. The survey was distributed at three diverse universities with 515 responses from students ranging from first year through graduate studies in a variety of engineering majors. The survey instrument was validated using principal components analysis, and internal reliability was established via high Cronbach’s alpha for each construct. Findings – Participation in more experiential, enriching learning experiences correlated to higher SE self-efficacy, value and affect. Extracurricular club involvement correlated with a lower self-efficacy but high SE value. Students who had participate...

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

AbstractA 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...
