With a plethora of technology available to support teaching and learning, preservice teachers are expected to become well-versed in technology literacy and competencies through their teacher education programs. This study examined preservice teachers' perceptions of technology competencies, based on newly issued International Society for Technology in Education (ISTE) Standards for Educators. A mixed-methods design was used to collect data at one of the national universities of education in South Korea. The preservice teachers viewed their current technology education courses as deficient: neither tailored to their technology competency levels, nor strategically aligned with each other. This study suggested that teacher education curricula should be redesigned to offer more and better opportunities for teachers to improve teaching technology skills that can be readily applied to classrooms.
