The focus of this chapter is the results of a 3-year implementation of a one-on-one laptop program in a Midwestern school district. Using a mixed methods quasi-experimental design including classroom observations; perception data from students, teachers, and parents; ‘and achievement scores from state-mandated and supplementary assessments of writing and problem-solving, we found that a technological innovation can serve as a change agent in making learning more problem-based and constructivist in nature. Further, the combination of the student “owned” laptops and the transformed classroom environment resulted in sustained gains in writing and problem-solving relative to comparison students. Implications for practice and research in technology integration are drawn from the results.
