Engineering education has traditionally focused on the development of technical skills and knowledge. Nowadays, the need for educating engineers in non-technical skills, such as reflective thinking, is being recognised internationally. This paper proposes that socio-cultural impacts of technology be studied together with the technology itself through the integration of social awareness modules into advanced technical courses, providing a venue for students to exercise their reflective thinking skills in the context of technologies that are of interest to them. The paper presents an exploratory study of the essays of senior year engineering students on the socio-cultural impacts of computer vision technologies. It provides insights on the themes that are of interest to the students and on the students' strengths and weaknesses relating to their reflective thinking abilities. Similar modules would apply well to other advanced courses in the engineering curriculum, to help contextualise technology and enhance the reflective abilities of engineering graduates.
