From Deborah Meier’s The Power of Their Ideas (cited in Vilardi and Chang, Writing-Based Teaching):

“For the kinds of changes necessary to transform American education, the work force of teachers must do three tough things more or less at once: change the way they view learning itself, develop new habits of mind to go with their cognitive understanding, and simultaneously develop new habits of work — habits that are collegial and public in nature, not solo and private, as has been the custom in teaching.”
