1) The document proposes a theoretical framework based on activity theory to holistically study ICT in schools. It argues ICT must be studied within the broader sociocultural context and activities it is situated in, not in isolation.
2) The framework uses an activity system as the unit of analysis, where an individual's goal-directed activity is mediated by tools and signs within the sociocultural setting. This allows observing how settings and cognition shape and are shaped by ICT tools.
3) Adopting this framework allows considering how ICT mediates activities in learning environments and how its use integrates into discourse and develops higher-order thinking, rather than just focusing on ICT itself.
