Through his lifelong teaching practice, Confucius accumulated a set of highly valuable educational methods.
First, Confucius advocated combining "learning" and "thinking," putting forward the insightful view: "Learning without thinking leads to confusion; thinking without learning leads to peril." He promoted being "fond of learning" and "learning without satiety," learning from people, from events, and from books. One should "learn and practice it regularly" and "review the old to understand the new." He believed that "when walking with three people, there must be a teacher among them" and that one should "not be ashamed to ask subordinates." He also held that a person who does not study diligently but merely engages in bitter contemplation gains nothing. He once said: "I once spent all day without eating and all night without sleeping, in order to think—it was of no benefit; it is better to learn." However, learning without analysis and thinking makes it difficult to understand and digest, leading to a state of confusion and helplessness. Confucius particularly emphasized independent thinking, earnestly questioning and pondering closely, tracing things to their roots, and asking "why" multiple times when encountering matters. He said: "When encountering matters, a person who does not ask 'what about this, what about that'—I can do nothing with such a person!" He criticized those "who eat their fill all day without using their minds," calling them intellectual sluggards, and taught his students to "listen more and reserve judgment on doubtful points," daring to discover problems in order to cultivate their thinking ability.
Second is teaching according to aptitude and guiding students step by step with skill. Confucius was adept at tailoring his teaching to students' actual conditions, addressing differences in intellectual ability. He said: "To those above average, one may talk about profound subjects; to those below average, one may not talk about profound subjects." In other words, for those with above-average intelligence, one can discuss advanced knowledge, while for those below average, one cannot. He taught different content based on students' varying aptitudes. He often gave different answers to the same question depending on the student. When Ran Qiu (a timid disciple who tended to shrink from action) was hesitant, Confucius taught him to seize the moment and act immediately upon hearing something; when Zhong You (Zi Lu, a bold and impulsive disciple) was overly daring, Confucius feared he might invite trouble through rashness and taught him to step back first and consult his elders before acting. Confucius was also skilled at understanding students' different temperaments and interests, guiding them step by step. He believed that a person should not only know the importance of learning but also take delight in it: "Those who know it are not equal to those who love it; those who love it are not equal to those who delight in it." Only by cultivating an interest in learning can one develop self-motivation, thereby generating enthusiasm for learning and never tiring of it.
Confucius often taught his students through vivid examples from daily life, using philosophical metaphors. For instance, he likened time to a flowing stream with "It passes on like this, never ceasing day or night," encouraging his disciples to cherish time. He also used "When the year grows cold, the pine and cypress are the last to wither" to symbolize moral integrity, teaching his students to endure hardship with perseverance and resilience. This teaching method was well-received by his disciples and achieved excellent results. Yan Hui (Confucius's most beloved disciple) once exclaimed, "The Master is good at leading one forward step by step."
Third, he was skilled in using the heuristic teaching method, paying attention to cultivating students' thirst for knowledge and learning initiative. He advocated: "Do not enlighten one who is not eager to learn; do not inspire one who is not trying to speak. When I have shown one corner of a subject and he cannot infer the other three, I will not repeat the lesson." This means that in educating students, one should cultivate their enthusiasm and initiative in learning, guiding them to think actively while teaching, and only when they still cannot grasp the key points after thinking should one enlighten them. Secondly, one should inspire them to express their opinions when they want to but cannot articulate them. Furthermore, one must ensure that students can draw inferences about other cases from one instance, achieving mastery through analogy; if having pointed out the east corner, they cannot infer the remaining west, south, and north corners, then there is no need to force further teaching.
Fourth, Confucius encouraged mutual discussion between teacher and students to achieve the benefit of teaching and learning from each other. The Analects records many dialogues and questions between Confucius and his disciples. He asked his students to share their aspirations, then expressed his own, and offered comments on each—an excellent method of positive education. Confucius also genuinely welcomed students to offer him feedback. His favorite disciple, Zi Lu (a straightforward and outspoken disciple), often criticized him. Once, when Gongshan Furao (a steward of the Ji family in the State of Lu) invited Confucius, and he was about to go, Zi Lu bluntly criticized: "Are you at your wit's end? Why must you go to Gongshan Furao, who is in rebellion?" Although Confucius explained himself, he heeded Zi Lu's advice and did not go. Another time, Fo Xi (a steward of the Fan family in the State of Jin) invited Confucius, and he again considered going. Zi Lu criticized: "I have heard you say that a Junzi (Exemplary Person) does not go to those who do evil. Now Fo Xi is rebelling in Zhongmou, yet you want to go. How can this be?" Confucius honestly admitted his eagerness to take office and earn a salary, but ultimately accepted Zi Lu's criticism and abandoned the plan. Yan Hui (Confucius's most beloved disciple) was highly praised by Confucius, but he always obeyed Confucius's words without question and never offered objections. Therefore, Confucius reproached him, saying that Yan Hui never raised differing opinions, thus failing to bring the benefit of mutual learning between teacher and student.
Confucius also created a teaching method that, through evaluations of historical figures and commentary on current political affairs, elucidated his own political views and philosophical ideas to his students. Confucius commented on many figures, ranging from the ancient sage-kings Yao, Shun, Yu, Tang, King Wen, King Wu, the Duke of Zhou, Bo Yi, and Shu Qi (two sons of the Lord of Guzhu), down to famous individuals of the Spring and Autumn Period (770-476 BCE) such as Guan Zhong (Prime Minister of Qi State) and Zi Chan (a renowned statesman of Zheng State), and he even evaluated his own disciples. Confucius granted Guan Zhong and Zi Chan the designation of Ren (Benevolence); regarding Bo Yi and Shu Qi, who yielded the throne to each other, Confucius said they "sought Ren and attained Ren." Confucius had clear likes and dislikes, and he criticized those who were unworthy and immoral. Zang Wenzhong, a high official of the State of Lu, knew that Liu Xia Hui was a virtuous and worthy man but refused to employ him; Confucius rebuked Zang for occupying his post without doing real work. Ji Kangzi oppressed and exploited the people, forcing many to become thieves out of desperation. When Ji Kangzi asked Confucius what to do, Confucius replied: "If you yourself were not greedy for wealth, even if you rewarded people for stealing, no one would steal!" Through his evaluations of people, Confucius taught his students to distinguish right from wrong and good from evil, establishing an ideal model of character for his disciples' self-cultivation. He closely watched and cared about current events, always stating his own attitude and promoting his doctrines. When the Ji family prepared to attack Zhuanyu, Ran You (a disciple) and Zi Lu (a disciple) reported this to Confucius, who firmly opposed the Ji family's military aggression and immediately stated his view: "For rulers of states and heads of families, they do not worry about scarcity but about inequality; they do not worry about poverty but about instability. For with equality there is no poverty, with harmony there is no scarcity, and with stability there is no danger of overthrow." From these comments, one can see Confucius's breadth of vision and ambition, which also reflect his excellent teaching style of integrating theory with practice through real-life examples.
