This document discusses the roles of educational technology in learning. It can serve as a delivery vehicle for instructional lessons or as a teacher itself. Technology tools like word processors, databases, and spreadsheets are productivity tools. The rise of the internet in the mid-1990s brought communications and multimedia to the classroom, providing opportunities for learner-technology interaction and meaningful learning. From a constructivist perspective, technology can serve as a tool for knowledge construction, an information vehicle for exploring knowledge, and a social medium for learning through conversation and as an intellectual partner for reflection. When used effectively, research shows technology increases learning, understanding, achievement, and motivation while encouraging collaboration and developing critical thinking and problem-solving skills.
