Teachers today face ever-increasing demands in teaching to ensure that their students are to be well equipped to be competent in the 21st century. Among many demands, teachers are expected to be fluent, versatile, and professional in using technology based on the taken-for-granted beliefs that technology has a good and innovative influence on education. However, while it is hard to hear that innovation has completed, it is easy to see teachers still find the effective integration of technology in their practices complicated. The purpose of the study is to investigate the formation of the gap between what has been commonly claimed regarding technology use and what has been seen by educators in the classrooms. By drawing Foucault’s theory of discourse and power, this research will examine a set of claims produced in the process of promoting an educational policy “SMART education” in South Korea. The study ultimately aims to demystify taken-for-granted assumptions related to SMART education which invisibly urge teachers to accept and conform regardless of what teachers find in their classrooms.
