The document discusses two views of educational technology - the traditional view where technology serves as a source and presenter of knowledge, and the constructivist view where technology serves as a learning tool. From the constructivist perspective, technology engages learners in active and collaborative learning, provides opportunities for learner-technology interaction to facilitate knowledge construction, and is used as a tool, information vehicle, social medium, and intellectual partner to support learning through knowledge representation, information access, discourse, and reflection.
