Locke believes that the task of teaching is to develop students' thinking and cultivate their ability to judge and summarize clearly, logically and step by step. He particularly emphasized that children should be allowed to "enhance their spiritual activities and abilities, rather than expand their spiritual possessions." Therefore, he strongly opposed the rote learning method popular in grammar schools at that time, and advocated that teaching should be pursued as a game and entertainment. In teaching, we should stimulate students' interest and let them feel the joy of learning; Students should not be intimidated by harsh methods, but should strive to maintain a "peaceful and quiet" atmosphere. He stressed: "You can't write straightforward words in a soldier's mind any more than you can write straightforward words on a vibrating piece of paper."
