Transdisciplinary Sustainable Product Design
Callie Babbitt and Alex Lobos
Teaching and Learning
Alex and Callie felt that traditional university-level training in their fields often concentrates within disciplines without providing the holistic knowledge required in the real world. Their idea is to build an integrated knowledge base for developing sustainable designs. They aimed to bridge this gap between the skills and experiences of students from these two disciplines and help them understand the social, economic, and environmental dimensions of sustainability and product design, while teaching them how to communicate in trans-disciplinary teams. Alex and Callie also realized that their design students needed more exposure to quantitative measures so they could evaluate the impact of their decisions on a broader scale. Working with the engineering students, the design students saw their product designs subjected to the methods and tools of quantitative analysis. Conversely, engineering students had to create solutions that applied the tools and requirements of good design.
Teaching Strategies and Tools
In their transdisciplinary product design studio course, Callie and Alex created a comprehensive learning environment for both engineering and design students. The course combines instructions and collaboration through instructor-student and peer-peer mediated interactions to provide cross-disciplinary experience. Students work in cross-functional teams to identify a sustainable product problem and create a sustainable design solution for it. This peer-to-peer mediated collaboration provides a rapid immersion for students in each other's discipline. In the process, they learn the tools and practices from each discipline from each other, with the instructors available to reinforce and scaffold learning. At the end of the quarter, students present their 3D design solutions in three-minute videos that communicate the product to an outside audience, highlighting the design innovation and sustainability concepts. In this way, students gain experience marketing their sustainable design solutions.

Experience and Results
The course has been well-received by students from both disciplines; course evaluations showed a 42 percent improvement in understanding the dimensions of sustainability and a marked improvement in incorporating sustainability concepts in their projects. Alex and Callie also observed that their problem-based, team approach often motivated students to assume roles in their teams naturally. For example, graduate students often acted as mentors to the un.dergraduates, resulting in increased synergy among the team, so students were comfortable contributing to the project based on their individual skill sets.
Conducting a transdisciplinary course has not been without challenges. Students come to the class with different backgrounds in vocabulary, tools, and techniques particular to their field. Getting them to collaborate from the same frame of reference often takes some time and adjustments. But with incremental adjustments, Alex and Callie have successfully offered this course for two quarters, and are excited that the new Golisano Institute of Sustainability building will include a dedicated Sustainable Product Innovation lab to help them further develop their transdisciplinary approach.
By collaborating on this interdisciplinary model, Alex and Callie have been able to secure corporate support from companies such as Autodesk® and AT&T®. Their students have also presented at various conferences by the Institute of Electrical and Electronics Engineers (IEEE), Industrial Designers Society of America (IDSA), and the E-Waste Symposium, and have won several international design competitions.
