How should we understand the development of modern technology? How have new technologies shaped our society, culture, and politics, and how have they been shaped? This class is designed to help engineers use historical thinking and methods to better understand the history of technology and their own engineering practices. We'll begin the course with an overview of major developments in the modern history of technology and continue by using topical case studies to ask questions such as whether the new technologies of the twentieth century really made homemakers' lives easier, or how the needs and experiences of students, teachers, and end-users shaped the development of computing in the 20th century. This is an inquiry- and project-based course, so rather than listening to lectures, we'll spend most of our time in class working together in groups using historical sources and scholarship to investigate big questions in the history of technology. We'll also have the opportunity to reflect critically on how historical thinking can inform our own engineering practice and on how best to narrate the history of technology to engineers.
