Engineers are responsible to many stakeholders, including the public and their employer. One such responsibility is considering and accounting for the potential impacts and risks associated with a technology that they create. A relatively new, and potentially risky, technology that has been on the rise over the past two decades is social media. The advent of social media, such as Facebook and Twitter, and its integration into our daily lives raises questions about the duty engineers bear for its responsible usage and design versus the responsibilities users have as they use the technology. This paper analyzes qualitative interview data from a study on engineering students’ perceptions of engineering ethics and social responsibility to answer the following research question: In what ways do students change (or not change) how they talk about engineers’ social and professional responsibilities to the technologies they create when framed in the context of social media? Our findings show that mentioning social media as a specific application of engineering ethics rendered visible the relationship between engineers, users, and technology that students then utilized to address the broader question about engineers’ responsibility to the technologies they create. In this study, a total of 33 students from three U.S. universities were interviewed longitudinally, once in the first year of their degree and again in the fourth year. In the interviews, the students were asked about their views on the social and professional duties engineers have for the technologies they create, framed in the context of social media. Analysis of student responses involved open and axial coding of relevant interview portions performed by two researchers to identify common themes and longitudinal changes between student interviews. These themes included: communication between the engineer and user, collective responsibility, benefits to society, high quality engineering, and misinformation. While students typically maintained elements of their views across both interviews, it was also common to see students change their responses to include new themes or exclude themes present in their initial interview. The students tended to believe that engineers have a responsibility to think through potential uses (or misuses) of their technology, but also believe that the users share some responsibility to use the technology appropriately. When social media was mentioned specifically, some students believed that the users were entirely responsible for how the technology is used, occasionally contradicting their views of engineering ethics when probed without the context of social media. This paper highlights the central tension between user responsibility and engineer responsibility. By illuminating students’ views, it will support educators in opening a dialogue with their students about who is ultimately responsible for the design and use of new technologies. 

Ethics and social responsibility are often viewed as key areas of concern for many engineering educators and professional engineers. Thus, it is important to consider how students and professionals understand and navigate ethical issues, explore how such perceptions and abilities change over time, and investigate if certain types of interventions and experiences (e.g., coursework, training, service activities, etc.) impact individual participants. The breadth of engineering as a profession also raises questions about how ethics and social responsibility are understood across a wide range of disciplines, subfields, and industry sectors. Recognizing a need for more empirical research to address such questions, our research team carried out a five year, longitudinal, mixed-methods study to explore students’ perceptions of ethics and social responsibility. This study relied on repeated use of quantitative measures related to ethics, along with qualitative interviews to explore how students’ perceptions of these issues change across time, between institutions, and in response to participation in certain experiences. Additionally, we are now initiating a follow-on study where we will collect survey and interview data from our previous participants now that most of them are in full-time job roles and/or pursuing graduate degrees, as well as from a new group of early career engineers to enlarge our sample. In this paper, we first give an overview of key research findings from our ongoing research that have been published or are under review. The second major part of this paper delves into some specific theoretical and methodological questions and challenges associated with our research. This paper will likely be of interest to educators and researchers who are involved with developing and/or evaluating ethical capabilities among engineering students.
