School districts all over America are embracing technology because they view technology as a stimulate to improve teaching and learning. Leading to additional investments in technology initiatives for academic improvement. The one-to-one laptop program is an initiative that continues to gain attention and peek momentum in the educational community. Even with widespread adoption, many teachers continue to face challenges with the use of technology in the classroom. Research has shown that teacher self-efficacy is a significant indicator of technology use; there is limited evidence on how a one-to-one laptop program can influence teacher self-efficacy. The purpose of this qualitative study was to describe the teacher perceptions and experiences of teachers who participated in a one-to-one laptop program at the high school level. The study was framed through the construct of self-efficacy by Bandura and constructivist theory by Dewey.
