Digital technologies have raised important ethical questions. Although often the focus is how ethical issues arise from ways people have used these technologies, there is growing interest in ethical values associated with the design and development of digital systems and devices. The study of values in, or values embodied in technology, has grown in importance as engineers and computer, and data scientists have acknowledged that sound ethical practice is a responsibility alongside technical. This module introduces students to the latter. After providing a background to this way of thinking — about ethics as a dimension of technology design and development – it introduces students to Values at Play, one particular approach to putting these ideas into practice. Students are encouraged to apply this learning to their own projects.
