the technology of e-learning:
1. 1st generation: used text books. phone and e-mails. behaviorist. freedom in time and place.
2. 2nd generation: used cognitive theory, restrict for time or place. used computer assisted instruction (CD). the teacher is only for evaluation and guidnes.
3. 3rd generation: gives opportunity for students to recreate knowledge: collaborative and critical thinking. used audio, video and telecommunications.
