Teachers reacquaint themselves with the joy and challenge of learning something new. Teachers experience new ways of thinking, learning and expressing one's knowledge. Teachers become more collaborative with colleagues and students. Sense of professionalism and self-esteem are elevated. Thoughtful discussions about the nature of learning and the purpose of school become routine and sometimes passionate.
Teachers have ability to collaborate with teachers around the world.
New scheduling, curriculum and assessment structures emerge. This is why I like laptops - you can take them home. I m not very impressed with computers that schools have chained to desks. You can't do any single thing and solve the problem. The current bureaucracy is a dying institution.
