1. A problem will put is half solved.

Logic: Theory of Inquiry (John Dewey, 1938: 108)

一个问题提得好，就已经解决了一半。《逻辑：提问论》 （约翰·杜威 1938：108）

2. Were all instructors to realize that the quality of mental process, not the production of correct answers, is the measure of educative growth. Something hardly less than a revolution in teaching would be worked. Democracy and education. (John Dewey)

若所有的教师都能认识到“衡量教育是否进步的尺度是精神发展的质量，而非正确答案的数量”就好了。这一认识的转变所能造成的影响不亚于一场教育革命。《民主与教育》（约翰·杜威）
