A TechnoEthical Framework for Teachers (TEFT) is introduced to aid educators in selecting and employing educational technologies in ethically sound and pedagogical sensitive ways in their classrooms. TEFT views technology through three key technoethical lenses or perspectives: instrumental, sociomaterial and existential. The instrumental lens is most familiar to teachers and focuses on the policies and laws governing teachers' and students' uses of technology. The sociomaterial perspective attends to technology's built-in biases and how it translates behaviour in prescribed or circumscribed ways. The existential lens considers how students' and teachers' entanglements with technology condition how they experience the world and transform their ways of knowing, doing, being and becoming. Taken together, these three approaches provide teachers with a theoretically robust view of the ethical implications of using technology in the classroom.
