In this course, students learn about STS (Science, Technology and Society) through case studies. What is this called science? How can we manage the conflicts between S&T and Society? Who are the experts? These questions appear in various issues around us, such as the pandemic of COVID-19, environmental problems, disasters, and emerging technologies. In this course, we learn about, and discuss cases from STS perspectives. Students are required to do their own case analysis in their final report.
