Technology integration has become increasingly important in high school education in recent years. As technology becomes more prevalent in society, it is essential that high school students can use technology in their everyday lives. Technology integration can help high school students become more independent learners and help them better understand and retain information. The purpose of this study is to explore high school teachers' perceptions of technology integration on students' learning. The study will use a mixed-methods approach, collecting data through one-one-one interview using Zoom as a communication platform, and focus groups. The data will be analyzed to examine teachers' beliefs about technology integration and its impact on students' learning. The case study was conducted in a small high school in an urban school district on the Eastern coast of the United States. Ten teachers were interviewed and asked to participate in a focus group. The study's results will be used to improve high school teachers' understanding of technology integration and its impact on students' learning.
