Educational technology can play both traditional and constructivist roles in learning. Traditionally, technology delivers instructional content similarly to a teacher. However, from a constructivist perspective, technology helps learners build their own interpretations of the world by engaging them in active, meaningful learning processes. It can serve as a tool for knowledge construction, an information vehicle for exploring perspectives, and a social medium and intellectual partner for learning through discourse, reflection, and problem-solving in real-world contexts. When used from either role, research shows technology increases student learning, understanding, achievement, and motivation to learn collaboratively.
