One-to-One Technology Device Integration in Grades 3-5 and the Beliefs & Actions of Teachers and District-Level Leaders One-to-One technology initiatives began in the 1990's and have expanded over time. It is not about distributing devices but rather how those devices transform teaching and learning. Educators need to harness the power of technology devices to engage students in learning, enhance teaching, and provide opportunities for personalized learning. The International Society for Technology in Education (ISTE) has developed student standards that provide a framework for teachers to guide them in developing content-rich lessons that are supported and enhanced by the use of technology devices. The purpose of this study was to examine how teachers in grades three through five operationalize the seven ISTE student standards in schools with one-to-one technology devices. The types of projects designed and implemented with students, as well as the actions taken by leaders to provide systems of instructional technology support, professional development opportunities and systems for learning for teachers was explored. Data was collected through interviews with third through fifth grade teachers and leaders in two districts that have implemented one-to-one student technology devices in their schools. A qualitative design was used and data was collected from interviews with twelve leaders, six teachers and a technology integration specialist from two school districts in the Capital Region of New York State that had implemented one-to-one initiatives in their districts. The data was analyzed to develop findings to answer three research questions. The findings of this study indicate that educational leaders who have implemented one-to one student technology in their district recognize that it is not about the device but more about the learning. Teachers reported that one-to-one student technology devices do not replace quality instruction but rather see the devices as a tool to increase motivation and engagement. A formal assessment to gather data to determine the effectiveness of implementing one-to-one student technology devices is needed. Conclusions from this study indicate that one-to-one student technology provide the opportunity for teachers to engage students in learning, differentiate and personalize learning, and allow students to be creators of their own learning. This study indicates that when implementing a one-to-one initiative, leaders who provide time for professional development through the creation of social networks of learning and technical support for student technology devices foster the successful implementation of a one-to-one initiative. Recommendations include supporting professional development on the ISTE standards, designing schedules that provide common time for teachers to learn about technology integration, requiring the inclusion of professional development for technology integration in district professional development plans and teacher and leader certification programs, and future studies.
