Our main aim is to categorise the different uses teachers and students make of ICT as a teaching and learning tool in technology-rich classrooms. A questionnaire about possible uses was developed following the guidelines provided by the literature review. A sample of teachers (n=278) who teach in highly technological classrooms participated in the study. Four types of educational ICT use in the classroom turned out of the exploratory factor analysis: teachers' technology use of content, teachers' technology use of interaction, students' technology use of content, and students' technology use of interaction. Useful ideas for researchers and teachers are provided.
