Educational technology assists students and teachers, but little information is available for high school education. The problem this study explored was whether there were inconsistencies in the use of educational technology in high school classrooms between public and private institutions, what factors may be influencing any discrepancies, and if educational technology was perceived to provide a differentiated and UDL-compliant learning environment for students. The purpose of this qualitative case study was to explore teachers' perceptions of using ed-tech in their classes for creating a differentiated and UDL-compliant learning environment. An additional aim was to investigate differences in educational technology implementation between public and private high schools in South Florida. Using connectivism as the framework, 16 active classroom teachers within an urban county in South Florida, equally divided between public and private high schools, were given a questionnaire through Google Forms and interviewed via Zoom. The semi-structured question interviews were recorded, and transcribed, and the data were analyzed with MAXQDA. Patterns emerging through evidence-based thematic coding revealed differences in teacher perceptions, availability, and equity in educational technology between public and private institutions. Teachers perceived technology as a double-edged sword but found ed-tech could be used to create a differentiated and UDL-compliant learning environment. This study recommends more ed-tech equity between institutions, training, time, and monitoring software. Building on similar studies performed at collegiate levels, this research provides vital and absent information for high school students, teachers, and administrators assisting in bettering the profession and ultimately helping students reach maximal academic potential.
