Comment on Ellen Glanz's words from the last two paragraphs.

Glanz has since returned to teaching at Lincoln-Sudbury. Before her stint as a student, she would worry that perhaps she was demanding too much. "Now I know I should have demanded 11 more," she said. Before, she was quick to accept the excuses of students who came to class unprepared. Now she says, "You are responsible for learning it." But a crackdown is only a small part of the solution. 12 The larger issue, Glanz said, is that educators must recognize that teachers and students, though physically in the same school, are in separate worlds and have an on-going power struggle. "A first step toward ending this battle is to convince students that what we attempt to teach them is gen uinely worth knowing," Glanz said. "We must be sure, 'ourselves, that what we are teaching is worth knowing."​
