What is the difference between traditional learning and interactive teaching/ learning?
The simple answer is that in traditional learning a teacher provides instruction and the learners receive it passively. In interactive teaching and learning, there is a dialogue (in the classroom, with the teacher; in ODL a mental dialogue and engagement with the materials) and learners learn actively, eg doing learning activities rather than just listening or reading, applying what they learn, relating what they learn to their own experiences and previous knowledge.
