Margie's experience highlights the lack of what in education?

Correct answer: Shared joy

Margie’s experience highlights that technologically organised education can provide regular lessons and assessment while still missing the shared joy of learning with other people. She studies alone, has no classmates to talk with and never experiences the lively classroom atmosphere suggested by the old book. The title itself becomes meaningful because Margie imagines that children in the past had fun together at school. Option D is correct because shared joy includes companionship, conversation and common activities. A, B and C are not the central absence: her system still has timing, a curriculum and checking of work.
