Due to the impact of biomedical technologies on human wellbeing, biomedical engineering presents discipline-specific ethical issues that can have global, economic, environmental, and societal consequences. Because ethics instruction is a component of accredited undergraduate engineering programs in the US, we developed an ethics assignment that provided biomedical engineering students with a framework for ethical decision-making and challenged them to critically reflect on ethical issues related to contemporary medical devices. Thematic analysis performed on student reflections (n = 73) addressed two research (...) questions: (i) _what_ considerations do biomedical engineering undergraduates describe when asked to critically reflect on ethical issues related to contemporary medical devices; and (ii) _how_ do students describe their participation in bioethical discussions? Students described design, economic factors, and empathy most frequently as considerations. Further, students reported confidence in their ability to engage in ethical discussion upon assignment completion. Overall, our analysis builds understanding of student attitudes and engagement to help inform future ethics curriculum development. (shrink)
